A 63-year-old woman is brought to the emergency department because of severe abdominal pain and vomiting for 3 hours. She had previous episodes of abdominal pain that lasted for 10–15 minutes and resolved with antacids. She lives with her daughter and grandchildren. She divorced her husband last year. She is alert and oriented. Her temperature is 37.3°C (99.1°F), pulse is 134/min, and blood pressure is 90/70 mm Hg. The abdomen is rigid and diffusely tender. Guarding and rebound tenderness are present. Rectal examination shows a collapsed rectum. Infusion of 0.9% saline is begun and a CT of the abdomen shows intestinal perforation. The surgeon discusses the need for emergent exploratory laparotomy with the patient and she agrees to it. Written informed consent is obtained. While in the holding area awaiting emergent transport to the operating room, she calls for the surgeon and informs him that she no longer wants the surgery. He explains the risks of not performing the surgery to her and she indicates she understands but is adamant about not proceeding with surgery. Which of the following is the most appropriate next step in management?
Q12
A 22-year-old man is brought to the emergency department by his friends 30 minutes after falling down a flight of stairs. His friends report that they were at a college party, where he drank large amounts of alcohol. He is aggressive and restless. Examination shows tenderness to palpation and swelling of his right lower leg. An x-ray of the right leg shows a lower tibial shaft fracture. The physician recommends overnight observation and surgery the following morning. The patient refuses the suggested treatment and requests immediate discharge. Otherwise, he says, he will call his lawyer and sue the entire medical staff involved in his care. Which of the following is the most appropriate response by the physician?
Q13
A 32-year-old man is brought to the emergency department by the police for examination. The police have reason to believe he may have swallowed a large number of cocaine-containing capsules during an attempt to smuggle the drug across the border. They request an examination of the patient to determine if this is actually the case. The patient has no history of any serious illnesses and takes no medications. He does not smoke, drinks, or consume any drugs. He appears upset. His vital signs are within normal limits. Despite the pressure by the police, he refuses to undergo any further medical evaluation. Which of the following is the most appropriate next step in the evaluation of this patient?
Q14
Two days after hospital admission, a 32-year-old woman with breast cancer is visited by the attending physician in the presence of medical students. She has limited English proficiency. The attending physician describes the situation to the patient in English, and the patient nods understandably. Subsequently, the attending physician pulls down the patient’s hospital gown and exposes her breasts. The patient is clearly shocked and upset.

Q17
A 44-year-old female patient comes to the physician’s office with her husband with complaints of abdominal pain. For the past 4 months, she has experienced cramping right upper quadrant pain that starts after meals. The physician performs a right upper quadrant ultrasound that shows round echogenic masses in the gallbladder. The physician offers an elective cholecystectomy to the patient to improve her symptoms and explains the procedure in detail to the patient including potential risks and complications. The patient acknowledges and communicates her understanding of her diagnosis as well as the surgery and decides to proceed with the surgery in one month. The patient signs a form indicating her consent to this procedure. Which of the following must also be communicated to the patient at this time?
Q18
An 8-year-old boy is brought to the emergency department 3 hours after being bitten by his neighbor's dog. He was chasing the dog with a stick when it attacked him. He has fed the dog on multiple occasions and it has never bitten him before. His father saw the dog 2 hours after the incident and its behavior seemed normal. There is no personal or family history of serious illness in the family. The last vaccination the boy received was against varicella 2 years ago; he has never been immunized against rabies. He is not in acute distress. Vital signs are within normal limits. Examination shows a 2 cm (0.8 in) puncture wound on his left calf; there is minimal erythema around the wound. The remainder of the examination shows no abnormalities. A complete blood count is within the reference range. The wound is irrigated and washed with saline and chlorhexidine solution. Which of the following is the most appropriate next step in management?
Q19
An 18-year-old man comes to the physician with his parents for a routine health maintenance examination. He noticed a swelling on his back 7 months ago. He has a history of using intravenous heroin but has not used illicit drugs for the past 2 months. There is no personal or family history of serious illness. Vital signs are within normal limits. Examination shows a 2-cm soft, lobulated, mobile swelling on the right side of his upper back. The mass slips away from the fingers when its edges are palpated. Healed track marks are present in the bilateral cubital fossae. The patient is told that the mass on his back is most likely a lipoma, a benign mass consisting of fat tissue that does not require any further treatment. He is aware of the diagnosis and informs you that he wants it removed for cosmetic reasons. Four months ago, he had asked another physician to remove it but the physician refused to perform the procedure since he did not consider it necessary. The patient is counseled regarding the potential benefits and risks of the excision and that there is a chance of recurrence. His parents ask the physician not to perform the excision. However, the patient insists on undergoing the procedure. Which of the following is the most appropriate next step in management?
Q20
A 68-year-old man comes to the emergency department because of sudden onset abdominal pain for 6 hours. On a 10-point scale, he rates the pain as a 8 to 9. The abdominal pain is worst in the right upper quadrant. He has atrial fibrillation and hyperlipidemia. His temperature is 38.7° C (101.7°F), pulse is 110/min, and blood pressure is 146/86 mm Hg. The patient appears acutely ill. Physical examination shows a distended abdomen and tenderness to palpation in all quadrants with guarding, but no rebound. Murphy's sign is positive. Right upper quadrant ultrasound shows thickening of the gallbladder wall, sludging in the gallbladder, and pericolic fat stranding. He is admitted for acute cholecystitis and grants permission for cholecystectomy. His wife is his healthcare power of attorney (POA), but she is out of town on a business trip. He is accompanied today by his brother. After induction and anesthesia, the surgeon removes the gallbladder but also finds a portion of the small intestine is necrotic due to a large thromboembolism occluding a branch of the superior mesenteric artery. The treatment is additional surgery with small bowel resection and thromboendarterectomy. Which of the following is the most appropriate next step in management?

Question 11: A 63-year-old woman is brought to the emergency department because of severe abdominal pain and vomiting for 3 hours. She had previous episodes of abdominal pain that lasted for 10–15 minutes and resolved with antacids. She lives with her daughter and grandchildren. She divorced her husband last year. She is alert and oriented. Her temperature is 37.3°C (99.1°F), pulse is 134/min, and blood pressure is 90/70 mm Hg. The abdomen is rigid and diffusely tender. Guarding and rebound tenderness are present. Rectal examination shows a collapsed rectum. Infusion of 0.9% saline is begun and a CT of the abdomen shows intestinal perforation. The surgeon discusses the need for emergent exploratory laparotomy with the patient and she agrees to it. Written informed consent is obtained. While in the holding area awaiting emergent transport to the operating room, she calls for the surgeon and informs him that she no longer wants the surgery. He explains the risks of not performing the surgery to her and she indicates she understands but is adamant about not proceeding with surgery. Which of the following is the most appropriate next step in management?
A. Consult hospital ethics committee
B. Obtain consent from the patient's daughter
C. Obtain consent from the patient's ex-husband
D. Continue with emergency life-saving surgery
E. Cancel the surgery (Correct Answer)
Explanation: ***Cancel the surgery***
- The patient is **alert and oriented** and has indicated she understands the risks of refusing surgery, demonstrating **decision-making capacity**. An adult with intact capacity has the right to refuse medical treatment, even if it is life-saving.
- While the decision may seem medically unwise, **patient autonomy** is a fundamental ethical principle that must be respected once capacity is confirmed.
*Consult hospital ethics committee*
- An ethics committee consultation is typically reserved for situations where there is **uncertainty about a patient's capacity**, a conflict among healthcare providers, or a difficult ethical dilemma where principles of patient care are in clear conflict.
- In this case, the patient's capacity seems clear, and her refusal is unequivocal.
*Obtain consent from the patient's daughter*
- The patient's daughter cannot provide consent for her mother if the mother is **competent and able to make her own decisions**. **Surrogate decision-makers** are only legally authorized when the patient lacks capacity.
- The patient's expressed wishes directly override any potential preferences of her next-of-kin.
*Obtain consent from the patient's ex-husband*
- As the patient is divorced, her ex-husband has **no legal standing** to make medical decisions on her behalf.
- Even if they were still married, a spouse can only act as a surrogate if the patient lacks decision-making capacity.
*Continue with emergency life-saving surgery*
- Performing surgery against a **competent patient's explicit refusal** would be an act of **battery** and a violation of her **autonomy**.
- Even in life-threatening situations, a patient with capacity has the right to refuse treatment.
Question 12: A 22-year-old man is brought to the emergency department by his friends 30 minutes after falling down a flight of stairs. His friends report that they were at a college party, where he drank large amounts of alcohol. He is aggressive and restless. Examination shows tenderness to palpation and swelling of his right lower leg. An x-ray of the right leg shows a lower tibial shaft fracture. The physician recommends overnight observation and surgery the following morning. The patient refuses the suggested treatment and requests immediate discharge. Otherwise, he says, he will call his lawyer and sue the entire medical staff involved in his care. Which of the following is the most appropriate response by the physician?
A. You can leave the hospital after signing a self-discharge against medical advice form.
B. If you don't consent to treatment, I'll be forced to obtain consent from your parents.
C. I understand that you want to go home, but I'll have to keep you here as long as you are intoxicated. (Correct Answer)
D. Have you ever felt you should cut down on your drinking?
E. I can't force you to stay here, but I'll have to inform your dean of this incident.
Explanation: ***I understand that you want to go home, but I'll have to keep you here as long as you are intoxicated.***
- An **intoxicated patient may lack decision-making capacity** to refuse medically necessary treatment for a serious injury.
- Before accepting a refusal of treatment or allowing AMA discharge, physicians must **assess the patient's capacity** to make informed decisions.
- Signs of impaired capacity include **acute intoxication, aggressive behavior, and restlessness**, all present in this patient.
- Temporarily holding a patient who lacks capacity and has a serious medical condition requiring urgent care is **legally and ethically justified** to prevent harm—this is NOT false imprisonment.
- Once the patient regains capacity (i.e., sobers up), his decision-making ability can be reassessed, and if he still refuses, AMA discharge can be offered.
*You can leave the hospital after signing a self-discharge against medical advice form.*
- While competent adults have the right to refuse treatment and leave AMA, this option is **premature** because it fails to address the patient's **impaired decision-making capacity** due to acute intoxication.
- A valid refusal requires **capacity to understand the risks and consequences** of leaving—offering AMA discharge without capacity assessment is inappropriate and potentially negligent.
*I can't force you to stay here, but I'll have to inform your dean of this incident.*
- Threatening to inform the patient's dean is a **breach of confidentiality** and an unprofessional response.
- Healthcare providers are bound by **patient confidentiality (HIPAA)**, and sharing this information without consent is unethical and illegal.
*If you don't consent to treatment, I'll be forced to obtain consent from your parents.*
- Since the patient is a **competent adult (age 22)**, his parents cannot give or withhold consent for his medical treatment.
- Parental consent is only required for **minors** or adults who have been legally declared **incompetent** through a court process.
*Have you ever felt you should cut down on your drinking?*
- While addressing alcohol use disorder is important, asking a **CAGE screening question** in this acute, high-stress situation is **inappropriate timing** and poor prioritization.
- The immediate priority is addressing the patient's **acute medical needs and impaired capacity**, not initiating a substance abuse screening.
Question 13: A 32-year-old man is brought to the emergency department by the police for examination. The police have reason to believe he may have swallowed a large number of cocaine-containing capsules during an attempt to smuggle the drug across the border. They request an examination of the patient to determine if this is actually the case. The patient has no history of any serious illnesses and takes no medications. He does not smoke, drinks, or consume any drugs. He appears upset. His vital signs are within normal limits. Despite the pressure by the police, he refuses to undergo any further medical evaluation. Which of the following is the most appropriate next step in the evaluation of this patient?
A. Examine the patient without his consent
B. Request a court order from the police
C. Obtain an abdominal X-ray
D. Refuse to examine the patient
E. Explain the risk of internal rupture to the patient (Correct Answer)
Explanation: ***Explain the risk of internal rupture to the patient***
- The primary responsibility of the physician is to the **patient's well-being**, not to law enforcement. Before any action, the patient must be fully informed of the **potential life-threatening risks**, such as capsule rupture and overdose, associated with concealing drugs internally, especially if they are asymptomatic.
- This approach respects the patient's **autonomy** while ensuring they understand the gravity of their situation, potentially motivating them to reconsider their refusal for medical evaluation for their own safety.
*Examine the patient without his consent*
- Examining an **adult patient without their consent** is a violation of ethical principles and could constitute **assault and battery**, regardless of police requests or suspected criminal activity.
- The patient's **competence** to refuse care is not questioned, and there is no immediate indication of a medical emergency that would override his refusal, as his vital signs are stable and he is not in distress.
*Request a court order from the police*
- While a court order might compel some medical procedures in specific legal contexts, it generally does not override a competent patient's right to refuse medical care, especially when they are **asymptomatic** and not in immediate danger.
- The physician's immediate ethical duty is to the patient's health and safety, not to facilitate legal processes that could infringe on patient rights without clear medical necessity.
*Obtain an abdominal X-ray*
- An abdominal X-ray is a medical procedure that requires patient consent. Performing it without consent would be a breach of **medical ethics** and patient rights, even if requested by police.
- Although an X-ray could confirm the presence of foreign objects, it should not be performed before **informed consent** is obtained or before the patient understands the potential risks they face due to the suspected objects.
*Refuse to examine the patient*
- While the patient initially refused examination, simply refusing to examine him at all would be negligent as it indicates a failure to address the potential medical emergency presented by suspected internal drug smuggling.
- The physician has a duty to at least **educate the patient** about the severe health risks involved, allowing him to make an informed decision about further medical evaluation.
Question 14: Two days after hospital admission, a 32-year-old woman with breast cancer is visited by the attending physician in the presence of medical students. She has limited English proficiency. The attending physician describes the situation to the patient in English, and the patient nods understandably. Subsequently, the attending physician pulls down the patient’s hospital gown and exposes her breasts. The patient is clearly shocked and upset. Her unease grows as the attending physician starts to palpate her breasts and she pulls up her gown in disbelief. Which of the following actions is most likely to improve similar miscommunications in the future?
A. Limiting encounters with such patients to noneducational visits
B. Asking a family member who knows English to interpret physician requests
C. Hiring a qualified medical interpreter in patients’ native languages (Correct Answer)
D. Employing medical staff with above-average familiarity with a language other than English
E. Providing written forms in different languages to bridge communication gaps
Explanation: ***Hiring a qualified medical interpreter in patients’ native languages***
- A **qualified medical interpreter** ensures accurate and complete communication, preventing misunderstandings about procedures, consent, and patient rights.
- This upholds the ethical principles of **respect for autonomy** and **beneficence** by ensuring the patient is fully informed and can provide true consent.
*Limiting encounters with such patients to noneducational visits*
- This action does not address the underlying communication barrier and could lead to **suboptimal care** if educational opportunities are linked to better understanding or patient engagement.
- It also raises ethical concerns about **equity** in patient care and limits learning opportunities for medical students.
*Asking a family member who knows English to interpret physician requests*
- While seemingly helpful, family members often lack **medical terminology knowledge**, may filter information, or may be reluctant to translate sensitive details, leading to **inaccurate interpretation**.
- This can also place an **undue burden** on family members and compromise patient confidentiality.
*Employing medical staff with above-average familiarity with a language other than English*
- While beneficial, "above-average familiarity" does not equate to the **professional linguistic and cultural competence** of a trained medical interpreter.
- This approach carries the risk of **misinterpretation** due to lack of specific medical vocabulary or understanding of subtle cultural nuances.
*Providing written forms in different languages to bridge communication gaps*
- Written forms can be a useful adjunct but are insufficient on their own, especially for complex discussions, immediate questions, and ensuring **comprehension of nuanced consent issues**.
- They do not address the need for **dynamic, real-time interactive communication** required during examinations or detailed medical explanations.
Question 15: A 32-year-old woman is brought to the emergency department by her husband because of an episode of hematemesis 2 hours ago. She has had dyspepsia for 2 years. Her medications include occasional ibuprofen for headaches. After initial stabilization, the risks and benefits of upper endoscopy and alternative treatments, including no therapy, are explained thoroughly. She shows a good understanding of her condition and an appreciation of endoscopic treatment and its complications. She decides that she wants to have an endoscopy to find the source of bleeding and appropriately manage the ulcer. Her medical records show advance directives that she signed 3 years ago; her sister, who is a nurse, has a durable power of attorney. Regarding obtaining informed consent, which of the following is the most accurate conclusion for providing endoscopic treatment for this patient?
A. There are reasons to believe that she may not have decision-making capacity
B. Endoscopic treatment may be performed without further action
C. Her sister must sign the consent form
D. Documentation of her decision prior to treatment is required (Correct Answer)
E. Her decision to have an endoscopy is not voluntary
Explanation: **Documentation of her decision prior to treatment is required**
- The patient has been fully informed, understands her condition, and has expressed a clear desire for the procedure, demonstrating **decision-making capacity**.
- To ensure ethical and legal compliance, her **informed consent** must be accurately documented in her medical record before any invasive treatment, including endoscopy, is performed.
*There are reasons to believe that she may not have decision-making capacity*
- The patient has clearly demonstrated **understanding of her condition, treatment options, and potential complications**, which indicates preserved decision-making capacity.
- Despite the acute medical situation, her ability to articulate her preference after a thorough discussion confirms her competence for informed consent.
*Endoscopic treatment may be performed without further action*
- While the patient has consented verbally, this does not negate the need for proper **documentation of informed consent** before initiating the procedure.
- Legally and ethically, a verbal agreement alone is insufficient; a signed consent form or detailed chart note confirming her understanding and decision is essential.
*Her sister must sign the consent form*
- Her sister, holding a **durable power of attorney**, would only be authorized to make medical decisions if the patient were deemed to lack **decision-making capacity**.
- Since the patient clearly demonstrates the ability to make her own medical decisions, her sister's consent is not required and would override the patient's autonomy.
*Her decision to have an endoscopy is not voluntary*
- The scenario explicitly states that the risks and benefits were **thoroughly explained**, and she shows a "good understanding" and "appreciation of endoscopic treatment."
- Her decision to "want to have an endoscopy" despite knowing the alternatives suggests a **voluntary and informed choice**, not coercion.
Question 16: A 16-year-old girl presents to the emergency room with her 8-month-old daughter for evaluation of "turning blue when she cries." The baby is found to have a congenital heart defect with right-to-left shunting, resulting in cyanosis and requiring surgical intervention. However, the mother wants to go to another hospital for a second opinion. Which of the following is the most appropriate next course of action?
A. Perform the surgery.
B. Consult the mother's parents because she is a minor.
C. Contact child protective services.
D. Allow the mother to take the patient for a second opinion. (Correct Answer)
E. Obtain a court order to perform the surgery.
Explanation: ***Allow the mother to take the patient for a second opinion.***
- As the baby's mother, the 16-year-old has the **legal right to make medical decisions** for her child, including seeking a second opinion, even if she is a minor.
- The baby is currently in a **stable condition** (requiring intervention but not in immediate, life-threatening distress), which allows for the mother to seek further consultation without putting the child at undue risk.
*Perform the surgery.*
- Performing surgery without the mother's **informed consent** would be a violation of her parental rights, even given the necessity of the procedure.
- While surgery is eventually needed, the scenario suggests the baby is not in acute extremis, allowing for the **brief delay** to obtain a second opinion.
*Consult the mother's parents because she is a minor.*
- In most jurisdictions, a minor parent (even if under the age of majority) is considered an **emancipated minor** solely for the purpose of making medical decisions for their own child.
- Therefore, the **grandparents' consent is not legally required** or even primary for the baby's medical care.
*Contact child protective services.*
- Seeking a second opinion, especially when the child's condition is not immediately life-threatening, does not constitute **medical neglect** or endangerment that would warrant CPS involvement.
- Involving CPS without proper cause can be **disruptive and traumatizing** for a family.
*Obtain a court order to perform the surgery.*
- A court order is typically sought when parents are **refusing necessary life-saving treatment** for their child without reasonable medical justification, or if parents are unavailable.
- In this case, the mother is not refusing treatment but merely seeking another medical opinion, which is a **reasonable request** that does not necessitate legal intervention at this point.
Question 17: A 44-year-old female patient comes to the physician’s office with her husband with complaints of abdominal pain. For the past 4 months, she has experienced cramping right upper quadrant pain that starts after meals. The physician performs a right upper quadrant ultrasound that shows round echogenic masses in the gallbladder. The physician offers an elective cholecystectomy to the patient to improve her symptoms and explains the procedure in detail to the patient including potential risks and complications. The patient acknowledges and communicates her understanding of her diagnosis as well as the surgery and decides to proceed with the surgery in one month. The patient signs a form indicating her consent to this procedure. Which of the following must also be communicated to the patient at this time?
A. The patient’s consent was not necessary for this procedure
B. The patient must give consent again before the procedure
C. The results of the procedure must be disclosed to her husband
D. A family member must also provide consent for this procedure
E. The patient has the right to revoke her consent at any time before the procedure (Correct Answer)
Explanation: ***The patient has the right to revoke her consent at any time before the procedure***
- **Informed consent** is an ongoing process, and a patient retains the right to withdraw consent at any point, even after signing, as long as they are **competent** to do so.
- This upholds the principle of **patient autonomy**, ensuring the patient maintains control over their medical treatment decisions.
*The patient’s consent was not necessary for this procedure*
- All surgical procedures require **informed consent** from a competent adult patient to be ethically and legally performed.
- Performing surgery without valid consent could be considered **battery**, even if the procedure is medically indicated.
*The patient must give consent again before the procedure*
- While patient consent is a continuous process, re-signing the same form is not always legally or ethically required immediately prior to the procedure if the initial consent was **valid** and no new information has emerged.
- However, the healthcare team should always re-verify the patient's understanding and willingness to proceed on the day of surgery, which is often a verbal confirmation, not necessarily a new signed document.
*The results of the procedure must be disclosed to her husband*
- This information is protected under **patient confidentiality** and **HIPAA**, meaning medical information cannot be shared with family members without the patient's explicit permission.
- Even though the husband accompanied her, the patient's consent is solely hers, and she has the right to control who accesses her medical information.
*A family member must also provide consent for this procedure*
- For a **competent adult patient**, only the patient herself can provide consent for her medical procedures.
- Family members are only involved in consent if the patient is deemed **incapacitated** or a minor, neither of which is indicated here.
Question 18: An 8-year-old boy is brought to the emergency department 3 hours after being bitten by his neighbor's dog. He was chasing the dog with a stick when it attacked him. He has fed the dog on multiple occasions and it has never bitten him before. His father saw the dog 2 hours after the incident and its behavior seemed normal. There is no personal or family history of serious illness in the family. The last vaccination the boy received was against varicella 2 years ago; he has never been immunized against rabies. He is not in acute distress. Vital signs are within normal limits. Examination shows a 2 cm (0.8 in) puncture wound on his left calf; there is minimal erythema around the wound. The remainder of the examination shows no abnormalities. A complete blood count is within the reference range. The wound is irrigated and washed with saline and chlorhexidine solution. Which of the following is the most appropriate next step in management?
A. Observe the dog for 10 days
B. Euthanize the dog and test for rabies
C. Administer rabies immune globulin
D. Administer rabies vaccine
E. Administer rabies vaccine and immune globulin (Correct Answer)
Explanation: ***Administer rabies vaccine and immune globulin***
- This is the **standard post-exposure prophylaxis (PEP)** for previously unvaccinated individuals with a potential rabies exposure per CDC guidelines.
- **Both components are required**: the vaccine provides active immunization while rabies immune globulin (RIG) provides immediate passive antibody protection during the window before vaccine-induced immunity develops.
- The dog should be observed for 10 days; if it remains healthy, the vaccine series can be discontinued after day 10, but **initial administration of both vaccine and RIG should not be delayed**.
- Rabies has a nearly 100% fatality rate once symptoms develop, making immediate complete prophylaxis critical.
*Administer rabies vaccine*
- Vaccine alone is appropriate only for **previously vaccinated** individuals requiring booster doses after exposure.
- For unvaccinated patients like this child, vaccine alone provides **insufficient immediate protection** since it takes time to generate antibody response.
- RIG must be given to provide immediate passive immunity while the vaccine series takes effect.
*Observe the dog for 10 days*
- Dog observation is an important **component** of management to determine if the vaccine series can be discontinued early.
- However, observation alone without initiating PEP is **dangerous** and violates standard rabies management protocols.
- PEP should begin immediately while the dog is observed; if the dog remains healthy for 10 days, rabies can be ruled out and vaccination stopped.
*Euthanize the dog and test for rabies*
- Euthanasia is reserved for animals that are **unavailable for observation**, become symptomatic, or when the owner refuses observation.
- Since this is a neighbor's dog with known location and normal behavior, observation is the preferred approach.
- Immediate euthanasia is unnecessary and would eliminate the opportunity to discontinue PEP if the dog remains healthy.
*Administer rabies immune globulin*
- RIG alone provides only **temporary passive immunity** lasting approximately 21 days.
- Without the vaccine to stimulate active immunity, the patient remains vulnerable once passive antibodies wane.
- Complete PEP requires both RIG for immediate protection and vaccine for sustained immunity.
Question 19: An 18-year-old man comes to the physician with his parents for a routine health maintenance examination. He noticed a swelling on his back 7 months ago. He has a history of using intravenous heroin but has not used illicit drugs for the past 2 months. There is no personal or family history of serious illness. Vital signs are within normal limits. Examination shows a 2-cm soft, lobulated, mobile swelling on the right side of his upper back. The mass slips away from the fingers when its edges are palpated. Healed track marks are present in the bilateral cubital fossae. The patient is told that the mass on his back is most likely a lipoma, a benign mass consisting of fat tissue that does not require any further treatment. He is aware of the diagnosis and informs you that he wants it removed for cosmetic reasons. Four months ago, he had asked another physician to remove it but the physician refused to perform the procedure since he did not consider it necessary. The patient is counseled regarding the potential benefits and risks of the excision and that there is a chance of recurrence. His parents ask the physician not to perform the excision. However, the patient insists on undergoing the procedure. Which of the following is the most appropriate next step in management?
A. Refer to the hospital ethics committee
B. Ask the patient to follow up in 6 months
C. Request parental consent
D. Perform the excision (Correct Answer)
E. Refer him to a methadone clinic
Explanation: ***Perform the excision***
- An **18-year-old** is considered an adult and has the **autonomy** to make his own medical decisions, even if his parents disagree, especially for an elective procedure.
- The patient has been **counseled** on the risks and benefits, indicating informed consent, and his desire for removal is for valid cosmetic reasons despite being benign.
*Refer to the hospital ethics committee*
- An ethics committee review is generally reserved for **complex ethical dilemmas** without clear legal precedents or for disputes that cannot be resolved through standard communication.
- In this case, the patient's right to **autonomy** is straightforward, and the situation does not present unusual ethical challenges beyond a disagreement between an adult patient and his parents.
*Ask the patient to follow up in 6 months*
- This option disregards the patient's expressed desire for the procedure and his **autonomy** in making medical decisions.
- While the mass is benign and delaying treatment might be medically acceptable, it fails to address the patient's **cosmetic concern** and preference.
*Request parental consent*
- The patient is **18 years old**, making him a legal adult, and therefore, parental consent is **not legally required** for his medical treatment.
- Seeking parental consent despite the patient's age would undermine his **autonomy** and his legal right to make independent decisions.
*Refer him to a methadone clinic*
- While the patient has a history of intravenous heroin use, he states he has not used illicit drugs for 2 months, and his request is for a **non-opioid-related cosmetic procedure**.
- Referring him to a methadone clinic without him expressing a need or desire for substance abuse treatment is **inappropriate** and unrelated to his current chief concern.
Question 20: A 68-year-old man comes to the emergency department because of sudden onset abdominal pain for 6 hours. On a 10-point scale, he rates the pain as a 8 to 9. The abdominal pain is worst in the right upper quadrant. He has atrial fibrillation and hyperlipidemia. His temperature is 38.7° C (101.7°F), pulse is 110/min, and blood pressure is 146/86 mm Hg. The patient appears acutely ill. Physical examination shows a distended abdomen and tenderness to palpation in all quadrants with guarding, but no rebound. Murphy's sign is positive. Right upper quadrant ultrasound shows thickening of the gallbladder wall, sludging in the gallbladder, and pericolic fat stranding. He is admitted for acute cholecystitis and grants permission for cholecystectomy. His wife is his healthcare power of attorney (POA), but she is out of town on a business trip. He is accompanied today by his brother. After induction and anesthesia, the surgeon removes the gallbladder but also finds a portion of the small intestine is necrotic due to a large thromboembolism occluding a branch of the superior mesenteric artery. The treatment is additional surgery with small bowel resection and thromboendarterectomy. Which of the following is the most appropriate next step in management?
A. Decrease the patient's sedation until he is able to give consent
B. Contact the patient's healthcare POA to consent
C. Proceed with additional surgery without obtaining consent (Correct Answer)
D. Ask the patient's brother in the waiting room to consent
E. Close the patient and obtain re-consent for a second operation
Explanation: ***Proceed with additional surgery without obtaining consent***
- In an **emergency situation** where immediate intervention is required to save a patient's life or prevent serious harm, and the patient **lacks capacity** to consent, explicit consent for additional necessary procedures is not required. The surgeon can proceed based on the principle of **implied consent** in emergencies.
- The discovery of **necrotic small bowel due to thromboembolism** is a life-threatening condition requiring urgent surgical intervention in an already sedated patient, making it an emergency.
*Decrease the patient's sedation until he is able to give consent*
- Decreasing sedation to obtain consent in this critical situation would cause a **dangerous delay** in treating a life-threatening condition (bowel necrosis) and could lead to worsening outcomes or death.
- The patient is **acutely ill** and likely in a state where he cannot grasp information and make decisions, even with reduced sedation, thus true informed consent would be difficult to obtain quickly.
*Contact the patient's healthcare POA to consent*
- Contacting the POA who is out of town would introduce **significant and potentially fatal delays** in treating a rapidly progressing, life-threatening condition.
- While POAs are crucial for non-emergent decision-making, the **principle of preserving life** takes precedence in an acute emergency when a delay would cause irreversible harm.
*Ask the patient's brother in the waiting room to consent*
- The brother is **not the designated healthcare POA** and there is no indication he has legal authority to make medical decisions for the patient.
- Relying on a non-POA family member for consent in an emergency, when the patient's legally appointed surrogate is known, is generally **not the appropriate first step** unless no other option exists and the brother can confirm the patient's wishes from prior discussions, which is not stated.
*Close the patient and obtain re-consent for a second operation*
- Closing the patient and then re-opening for another surgery would expose the patient to **two separate anesthetic events and surgical procedures**, significantly increasing morbidity and mortality risks compared to continuous surgery.
- This option would also introduce an **unacceptable delay** in addressing the acute bowel necrosis, which requires immediate intervention.
