Q5
A 62-year-old woman is brought to the physician by her daughter for the evaluation of weight loss and a bloody cough that began 3 weeks ago. Twenty years ago, she had a major depressive episode and a suicide attempt. Since then, her mental status has been stable. She lives alone and takes care of all her activities of daily living. The patient has smoked 1 pack of cigarettes daily for the past 40 years. She does not take any medications. An x-ray of the chest shows a central solitary nodule in the right lung; bronchoscopy with transbronchial biopsy shows a small cell lung cancer. A CT scan of the abdomen shows multiple metastatic lesions within the liver. The patient previously designated her daughter as her healthcare decision-maker. As the physician goes to reveal the diagnosis to the patient, the patient's daughter is waiting outside her room. The daughter asks the physician not to tell her mother the diagnosis. Which of the following is the most appropriate action by the physician?
Q6
Following the death of an 18-year-old woman, the task force determines a fatal drug interaction as the cause. The medical error is attributed to the fatigue of the treating resident. The report includes information regarding the resident’s work hours: The resident received the patient at the 27th hour of his continuous duty. Over the preceding month, he had been on duty a maximum of 76 hours per week and had provided continuity of care to patients up to a maximum of 30 hours on the same shift. He had only had 1 day per week free from patient care and educational obligations, and he had rested a minimum of 12 hours between duty periods. Regarding this particular case, which of the following is in violation of the most recent standards set by the Accreditation Council for Graduate Medical Education (ACGME)?
Q7
A 26-year-old woman presents to the emergency department for shortness of breath. She was walking up a single flight of stairs when she suddenly felt short of breath. She was unable to resolve her symptoms with use of her albuterol inhaler and called emergency medical services. The patient has a past medical history of asthma, constipation, irritable bowel syndrome, and anxiety. Her current medications include albuterol, fluticasone, loratadine, and sodium docusate. Her temperature is 99.5°F (37.5°C), blood pressure is 110/65 mmHg, pulse is 100/min, respirations are 24/min, and oxygen saturation is 85% on room air. On physical exam the patient demonstrates poor air movement and an absence of wheezing. The patient is started on an albuterol nebulizer. During treatment, the patient's saturation drops to 72% and she is intubated. The patient is started on systemic steroids. A Foley catheter and an orogastric tube are inserted, and the patient is transferred to the MICU. The patient is in the MICU for the next seven days. Laboratory values are ordered as seen below.

Q8
A 56-year-old man suffered seizure-like activity followed by a loss of consciousness within minutes after surfacing from a recreational 55-foot dive with some friends. His friends laid him on his side and called emergency services. Past medical history is significant for paroxysmal atrial fibrillation status post failed catheter ablation. Current medications are low-dose metoprolol, a daily baby aspirin, and a daily multivitamin. When the emergency response team arrived, they found the patient with altered mental status. His blood pressure was 92/54 mm Hg and heart rate was 115/min. On physical examination, his skin appears mottled and his breath sounds are shallow. Which of the following is the next best step in the management of this patient?

Medical Ethics US Medical PG Practice Questions and MCQs
Question 1: A patient was referred by a doctor to a radiologist for a CT scan and the doctor was given money for the referral. What is this unethical act called?
A. Criminal negligence
B. Commission
C. Medical maloccurrence
D. Fee splitting (Correct Answer)
E. Dichotomy
Explanation: ***Fee splitting***
- **Fee splitting** occurs when a healthcare provider (e.g., a doctor) receives payment for referring a patient to another healthcare provider or service (e.g., a radiologist).
- This practice is considered unethical and often illegal because it creates a financial incentive for referrals, potentially leading to unnecessary services or choices not based on the patient's best interest.
*Criminal negligence*
- **Criminal negligence** involves a reckless disregard for the safety of others, leading to harm, often in situations where a duty of care was owed.
- It is characterized by actions or inactions that demonstrate a gross deviation from the standard of care, resulting in injury or death, which is not the case in this scenario.
*Commission*
- In a medical context, **commission** generally refers to an action taken by a healthcare provider. While the act of referring a patient is a commission, it does not specifically define the unethical monetary exchange.
- The term "commission" alone does not convey the unethical nature of receiving money for a referral.
*Dichotomy*
- **Dichotomy** in medical ethics refers to the division of fees between two healthcare providers for services actually rendered (e.g., a surgeon and assistant surgeon splitting a surgical fee).
- While also ethically questionable in many contexts, dichotomy involves splitting fees for work performed, whereas fee splitting involves payment specifically for making a referral without providing additional services.
*Medical maloccurrence*
- **Medical maloccurrence** is a broad term that refers to an untoward event or bad outcome that occurs during medical care but does not necessarily imply negligence or wrongdoing.
- It describes an adverse event that may happen despite appropriate care, which is distinct from an unethical financial arrangement.
Question 2: An 11-year-old girl is experiencing symptoms of fever and sore throat, and a throat swab was taken for culture. After the culture, which bag should be used to discard the swab?
A. Blue bag
B. Red bag (Correct Answer)
C. White bag
D. Yellow bag
E. Black bag
Explanation: ***Red bag***
- This bag is designated for disposal of **infectious medical waste**, including items contaminated with blood, body fluids, or cultures.
- The throat swab, potentially containing pathogenic microorganisms, falls under this category of **biohazardous waste**.
*Blue bag*
- This bag is typically used for **reusable linen** or certain types of **non-infectious waste** in healthcare settings.
- It is not appropriate for discarding items that have been in contact with patient samples, like a throat swab.
*White bag*
- White bags are generally used for **general waste** or **non-hazardous office waste**, which is not infectious.
- A throat swab from a patient with a suspected infection is considered hazardous and infectious, making a white bag unsuitable.
*Yellow bag*
- Yellow bags are used for the disposal of **clinical waste** such as anatomical/pathological waste, pharmaceutical waste, or items requiring incineration.
- While some infectious waste may go in yellow bags, the red bag is more specifically designated for contaminated infectious waste like used swabs.
*Black bag*
- Black bags are used for **general non-hazardous waste** that does not pose any infectious or chemical risk.
- A used throat swab from a patient with suspected infection is biohazardous and must not be disposed of in a black bag.
Question 3: Which of the following is most appropriate for managing a blood spill?
A. Chlorhexidine
B. Formaldehyde
C. Ethyl Alcohol
D. Sodium Hypochlorite (Correct Answer)
E. Hydrogen Peroxide
Explanation: ***Sodium Hypochlorite***
- **Sodium hypochlorite** (bleach) is a widely recommended disinfectant for cleaning up blood spills due to its broad-spectrum antimicrobial activity.
- It effectively **inactivates viruses**, bacteria, and fungi, including bloodborne pathogens like HIV, HBV, and HCV.
- **CDC recommends** a 1:10 dilution of household bleach for blood spill decontamination with appropriate contact time.
*Chlorhexidine*
- **Chlorhexidine** is primarily an antiseptic used for skin disinfection before medical procedures.
- While it has antimicrobial properties, it is not the preferred agent for decontaminating surfaces from large blood spills due to its less potent virucidal action compared to bleach.
*Formaldehyde*
- **Formaldehyde** is a potent disinfectant and sterilant, often used in histology and for sterilizing medical equipment.
- However, it is highly toxic, a known carcinogen, and has a strong irritating odor, making it unsuitable for routine blood spill cleanup in clinical settings.
*Ethyl Alcohol*
- **Ethyl alcohol** (ethanol) is an effective antiseptic for skin and small surface disinfection, particularly against bacteria and some viruses.
- Its efficacy against non-enveloped viruses and spores is limited, and it evaporates quickly, which makes it less reliable for disinfecting large blood spills that require sustained contact time.
*Hydrogen Peroxide*
- **Hydrogen peroxide** has antimicrobial properties and is used for surface disinfection in some healthcare settings.
- However, it is less effective than sodium hypochlorite against certain bloodborne pathogens, requires higher concentrations for virucidal activity, and can be corrosive to some surfaces.
- It may be unstable in storage and loses potency over time, making it less reliable for blood spill management protocols.
Question 4: Swab is discarded in which color bin
A. White bag
B. Yellow bag (Correct Answer)
C. Red bag
D. Blue bag
E. Green bag
Explanation: ***Yellow bag***
- Items in the **yellow bag** include **infectious/clinical waste** that may or may not be contaminated with human waste and may contain chemicals or pharmaceutical waste.
- As **swabs** are used for collecting biological samples that may contain infectious agents, they are classified as **infectious waste** and must be disposed of in a yellow bag for appropriate incineration.
*White bag*
- **White bags** are typically used for the disposal of **amalgam waste**, which includes teeth with amalgam fillings (unless the tooth is a biopsy sample), removed amalgam fillings, and encapsulated dental amalgam.
- This category is distinct from general clinical waste, which swabs fall under.
*Red bag*
- **Red bags** are used for **anatomical waste**, which includes body parts, organs, and visible blood.
- **Swabs** do not fall into this category, as they are not anatomical waste, even if they contain blood.
*Blue bag*
- **Blue bags** are designated for the disposal of **pharmaceutical waste** that is not cytotoxic or cytostatic.
- This typically includes expired or unused medications, not general clinical waste like swabs.
*Green bag*
- **Green bags** are used for **general/non-infectious waste** such as disposable items not contaminated with body fluids.
- **Swabs** used for biological sample collection are considered infectious waste, not general waste, so they do not belong in green bags.
Question 5: A 62-year-old woman is brought to the physician by her daughter for the evaluation of weight loss and a bloody cough that began 3 weeks ago. Twenty years ago, she had a major depressive episode and a suicide attempt. Since then, her mental status has been stable. She lives alone and takes care of all her activities of daily living. The patient has smoked 1 pack of cigarettes daily for the past 40 years. She does not take any medications. An x-ray of the chest shows a central solitary nodule in the right lung; bronchoscopy with transbronchial biopsy shows a small cell lung cancer. A CT scan of the abdomen shows multiple metastatic lesions within the liver. The patient previously designated her daughter as her healthcare decision-maker. As the physician goes to reveal the diagnosis to the patient, the patient's daughter is waiting outside her room. The daughter asks the physician not to tell her mother the diagnosis. Which of the following is the most appropriate action by the physician?
A. Ask the patient if she wants to know the truth
B. Encourage the daughter to disclose the diagnosis to her mother
C. Withhold the diagnosis from the patient
D. Disclose the diagnosis to the patient
E. Clarify the daughter's reasons for the request (Correct Answer)
Explanation: ***Clarify the daughter's reasons for the request***
- The patient's **autonomy** and right to know her diagnosis are paramount unless she clearly indicates otherwise or lacks decision-making capacity.
- Before proceeding, understanding the daughter's concerns allows the physician to address them while upholding the patient's rights and ensuring empathetic communication.
*Ask the patient if she wants to know the truth*
- While patient preference is crucial, directly asking this question without first addressing the daughter's request can create an immediate conflict and potentially undermine trust.
- It might put the patient in an awkward position if she feels pressured by her daughter's presence or wishes.
*Encourage the daughter to disclose the diagnosis to her mother*
- Disclosing complex medical diagnoses, especially those with serious prognoses, is the physician's responsibility, given their expertise and ethical obligations.
- Shifting this burden to the daughter can cause her undue stress and may not guarantee that the information is conveyed accurately or empathetically.
*Withhold the diagnosis from the patient*
- Withholding a diagnosis from a **competent patient** violates their **autonomy** and ethical principles of informed consent.
- The patient has no apparent cognitive impairment, lives independently, and has the right to make decisions about her own care.
*Disclose the diagnosis to the patient*
- While ultimately the correct action if the patient wishes to know, it's not the *most appropriate initial* action in light of the daughter's explicit request.
- Proceeding without understanding the daughter's concerns first could lead to immediate family conflict and complicate future care discussions.
Question 6: Following the death of an 18-year-old woman, the task force determines a fatal drug interaction as the cause. The medical error is attributed to the fatigue of the treating resident. The report includes information regarding the resident’s work hours: The resident received the patient at the 27th hour of his continuous duty. Over the preceding month, he had been on duty a maximum of 76 hours per week and had provided continuity of care to patients up to a maximum of 30 hours on the same shift. He had only had 1 day per week free from patient care and educational obligations, and he had rested a minimum of 12 hours between duty periods. Regarding this particular case, which of the following is in violation of the most recent standards set by the Accreditation Council for Graduate Medical Education (ACGME)?
A. The number of days per week this resident was free from patient care and educational obligations
B. The duty hour during which this resident received the patient (Correct Answer)
C. The minimum rest hours this resident had between duty periods
D. The maximum number of hours allowed for continued patient care
E. The maximum number of hours per week this resident was on duty
Explanation: **The duty hour during which this resident received the patient**
- The ACGME prohibits interns (first-year residents) from admitting new patients after **16 hours of continuous duty**.
- This resident received the patient at the **27th hour** of continuous duty, clearly exceeding the ACGME's maximum patient care shift limit for interns.
*The number of days per week this resident was free from patient care and educational obligations*
- The ACGME requires residents to have a minimum of **one day in seven free from patient care duties**, averaged over four weeks.
- The resident having "only 1 day per week free" meets this general standard.
*The minimum rest hours this resident had between duty periods*
- The ACGME requires a minimum of **10 hours free of duty** between scheduled duty periods.
- The resident rested a minimum of **12 hours**, which exceeds the ACGME minimum.
*The maximum number of hours allowed for continued patient care*
- The ACGME limits continuous duty for interns to **16 hours** and for other residents to **24 hours plus 4 hours for continuity of care activities**, for a total of 28 hours.
- While the resident was on duty for 27 hours before receiving the patient, the violation specifically concerns the **admission of a new patient past the 16-hour mark**, not necessarily the total continuous care hours for an entire rotation.
*The maximum number of hours per week this resident was on duty*
- The ACGME mandates a maximum of **80 duty hours per week**, averaged over a four-week period.
- The resident's schedule of "a maximum of 76 hours per week" falls within this established limit.
Question 7: A 26-year-old woman presents to the emergency department for shortness of breath. She was walking up a single flight of stairs when she suddenly felt short of breath. She was unable to resolve her symptoms with use of her albuterol inhaler and called emergency medical services. The patient has a past medical history of asthma, constipation, irritable bowel syndrome, and anxiety. Her current medications include albuterol, fluticasone, loratadine, and sodium docusate. Her temperature is 99.5°F (37.5°C), blood pressure is 110/65 mmHg, pulse is 100/min, respirations are 24/min, and oxygen saturation is 85% on room air. On physical exam the patient demonstrates poor air movement and an absence of wheezing. The patient is started on an albuterol nebulizer. During treatment, the patient's saturation drops to 72% and she is intubated. The patient is started on systemic steroids. A Foley catheter and an orogastric tube are inserted, and the patient is transferred to the MICU. The patient is in the MICU for the next seven days. Laboratory values are ordered as seen below.
Hemoglobin: 11 g/dL
Hematocrit: 33%
Leukocyte count: 9,500 cells/mm^3 with normal differential
Platelet count: 225,000/mm^3
Serum:
Na+: 140 mEq/L
Cl-: 102 mEq/L
K+: 4.0 mEq/L
HCO3-: 24 mEq/L
BUN: 21 mg/dL
Glucose: 129 mg/dL
Creatinine: 1.2 mg/dL
Ca2+: 10.1 mg/dL
AST: 22 U/L
ALT: 19 U/L
Urine:
Color: amber
Nitrites: positive
Leukocytes: positive
Sodium: 12 mmol/24 hours
Red blood cells: 0/hpf
Which of the following measures would have prevented this patient's laboratory abnormalities?
A. Nitrofurantoin
B. Avoidance of systemic steroids
C. Sterile technique
D. TMP-SMX
E. Intermittent catheterization (Correct Answer)
Explanation: ***Intermittent catheterization***
- The patient developed a **urinary tract infection (UTI)**, as evidenced by positive nitrites and leukocytes in the urine, in the context of indwelling Foley catheterization. **Intermittent catheterization** can reduce the risk of UTIs compared to continuous indwelling catheters.
- The patient's presentation with **acute asthma exacerbation** necessitated intubation and subsequent transfer to the MICU where a Foley catheter would have been placed to monitor urine output during this critical period.
*Nitrofurantoin*
- **Nitrofurantoin** is an antibiotic used to treat UTIs. While appropriate for treatment, it would not have prevented the development of the infection itself.
- It works by interfering with bacterial enzyme systems and cell wall synthesis, thus *treating* an infection rather than *preventing* its occurrence due to catheterization.
*Avoidance of systemic steroids*
- The patient was started on **systemic steroids** for a severe asthma exacerbation, which was a necessary and appropriate treatment to reduce airway inflammation.
- While systemic steroids can have side effects, they are crucial for managing **severe asthma exacerbations** and are not directly linked to the development of the UTI in this scenario.
*Sterile technique*
- **Sterile technique** is always crucial during catheter insertion to minimize the immediate introduction of bacteria. However, even with perfect sterile technique during insertion, the presence of an indwelling foreign body (Foley catheter) over several days significantly increases the risk of bacterial colonization and subsequent UTI, which intermittent catheterization helps to mitigate.
- The issue here was the *duration* and *type* of catheterization, not necessarily a failure of initial sterile technique.
*TMP-SMX*
- **TMP-SMX (trimethoprim-sulfamethoxazole)** is an antibiotic often used to treat UTIs, similar to nitrofurantoin.
- As a treatment, it would not have prevented the development of the catheter-associated UTI.
Question 8: A 56-year-old man suffered seizure-like activity followed by a loss of consciousness within minutes after surfacing from a recreational 55-foot dive with some friends. His friends laid him on his side and called emergency services. Past medical history is significant for paroxysmal atrial fibrillation status post failed catheter ablation. Current medications are low-dose metoprolol, a daily baby aspirin, and a daily multivitamin. When the emergency response team arrived, they found the patient with altered mental status. His blood pressure was 92/54 mm Hg and heart rate was 115/min. On physical examination, his skin appears mottled and his breath sounds are shallow. Which of the following is the next best step in the management of this patient?
A. Obtain a noncontrast head CT and administer tissue plasminogen activator (tPA).
B. Obtain an electrocardiogram and bolus amiodarone.
C. Insert 2 large bore IVs and start high volume fluid resuscitation.
D. Secure the patient’s airway and administer 100% oxygen and rapid transport for recompression in a hyperbaric chamber. (Correct Answer)
E. Give a loading dose of phenytoin followed by 12-hour infusion.
Explanation: ***Secure the patient’s airway and administer 100% oxygen and rapid transport for recompression in a hyperbaric chamber.***
- The patient's symptoms (seizure-like activity, altered mental status, mottling post-dive) are highly suggestive of **decompression sickness (DCS)**, specifically arterial gas embolism.
- **Securing the airway** and administering **100% oxygen** are critical initial steps to improve gas exchange and reduce nitrogen partial pressure, while **rapid transport for hyperbaric recompression** is the definitive treatment to reduce bubble size and facilitate gas elimination.
*Obtain a noncontrast head CT and administer tissue plasminogen activator (tPA).*
- While a head CT might eventually be considered to rule out other intracranial pathology, his presentation after diving makes **decompression sickness** the primary concern, requiring immediate oxygen and recompression.
- **tPA** is indicated for acute ischemic stroke, and administering it without confirming the cause and ruling out hemorrhagic stroke in a hypotensive patient with possible DCS would be inappropriate and potentially harmful.
*Obtain an electrocardiogram and bolus amiodarone.*
- The patient's tachycardia (HR 115/min) and history of paroxysmal atrial fibrillation could suggest a cardiac arrhythmia, but his overall presentation with hypotension, mottling, and neurological symptoms post-dive points away from an isolated cardiac event as the primary problem.
- While an ECG is standard, **amiodarone bolus** is not the immediate priority for a patient with suspected severe DCS and shock; addressing the dive-related injury is paramount.
*Insert 2 large bore IVs and start high volume fluid resuscitation.*
- Although the patient is hypotensive, **high volume fluid resuscitation** alone is not the definitive treatment for decompression sickness, and the priority is oxygenation, airway management, and recompression.
- While IV access is important for supportive care, it is secondary to securing the airway, administering oxygen, and arranging definitive treatment for a gas embolism.
*Give a loading dose of phenytoin followed by 12-hour infusion.*
- The patient experienced "seizure-like activity," but treating this as primary epilepsy with **phenytoin** without addressing the underlying cause (likely gas embolism from diving) would delay appropriate care.
- Seizures secondary to DCS require treatment of the DCS rather than just symptomatic seizure control.
Question 9: A hospital committee is established in order to respond to a national report on the dangers of wrong site surgery. The committee decides to conduct an investigation using a method that will hopefully prevent wrong site surgery from occurring prior to having any incidents. Therefore, the committee begins by analyzing systemic, design, process, and service issues. Which of the following components is a part of the analytical process being used by this committee?
A. Simplification
B. Failure modes (Correct Answer)
C. Root causes
D. Safety culture
E. Plan-Do-Study-Act cycles
Explanation: ***Failure modes***
- The committee's proactive approach of analyzing systemic, design, process, and service issues to prevent future incidents aligns with **Failure Mode and Effects Analysis (FMEA)**, which identifies potential failure modes before harm occurs.
- FMEA specifically focuses on identifying **potential points of failure** in a process and evaluating their causes and potential effects.
*Simplification*
- While simplifying processes can be a result of improvement efforts, it is not an analytical component used for proactively identifying potential failures.
- Simplification is a strategy to reduce complexity, not a method for analyzing risks.
*Root causes*
- **Root cause analysis (RCA)** is typically performed **after an incident has occurred** to determine what went wrong, rather than proactively identifying potential failures.
- The question states the committee aims to prevent wrong-site surgery "prior to having any incidents."
*Safety culture*
- A strong **safety culture** is an essential foundation for preventing errors, but it is an organizational characteristic rather than an analytical method for identifying specific failure points.
- It influences behaviors and attitudes, but doesn't provide a systematic way to analyze process failures.
*Plan-do-study-act cycles*
- **PDSA cycles** are iterative improvement cycles used to test changes on a small scale and learn from them.
- While integral to continuous improvement, PDSA is an implementation and evaluation framework, not a primary analytical tool for identifying hypothetical system failures.
Question 10: A 45-year-old male comes into the trauma bay by EMS transport with a known history of gross contamination of an unknown dry/powder chemical from a research laboratory accident. Currently his vital signs are stable but he is in obvious discomfort with diffuse skin irritation. What should be done for this patient during the primary survey?
A. Brush off the gross amount of unknown chemical and then remove all of the patient's clothes (Correct Answer)
B. Sedate and intubate the patient for concern of poor airway protection
C. Cover the patient's skin burns with topical mineral oil
D. Dilute the unknown substance load by washing the patient off in a chemical burn shower
E. Take a sample of the unknown substance and send it to the lab for stat identification
Explanation: ***Brush off the gross amount of unknown chemical and then remove all of the patient's clothes***
- **Decontamination** is the critical first step in managing exposure to dry chemicals, beginning with **brushing off** the powder to prevent further absorption and skin irritation.
- **Removing all clothing** is essential as contaminated clothes can harbor the chemical, continuing exposure and hindering proper decontamination.
*Sedate and intubate the patient for concern of poor airway protection*
- While airway protection is crucial, the patient's current vital signs are **stable**, and there's no immediate indication of respiratory distress or altered mental status to warrant **sedation and intubation** at this stage.
- Focusing on **decontamination** first addresses the immediate source of harm, while continuous monitoring will determine if airway intervention becomes necessary.
*Cover the patient's skin burns with topical mineral oil*
- Applying **mineral oil** or any other occlusive agent to chemical burns without prior decontamination can **trap the chemical** against the skin, potentially increasing absorption and worsening the injury.
- The immediate priority is to **remove the chemical**, not to treat the irritation with a potentially harmful substance.
*Dilute the unknown substance load by washing the patient off in a chemical burn shower*
- For **dry powder chemicals**, directly washing with water can be detrimental as some substances react violently with water, generating heat or forming corrosive solutions, and potentially spreading the chemical to unaffected areas.
- The standard procedure for dry chemicals is to **brush off** the powder *before* considering irrigation.
*Take a sample of the unknown substance and send it to the lab for stat identification*
- While identifying the substance is important for specific treatment, this step is **not part of the primary survey** and should not delay immediate decontamination.
- The priority in the primary survey is to **address life-threatening conditions** and prevent further harm, which in this case means removing the chemical from the patient.
