A 40-year-old woman presents to her physician's home with a headache. She describes it as severe and states that her symptoms have not been improving despite her appointment yesterday at the office. Thus, she came to her physician's house on the weekend for help. The patient has been diagnosed with migraine headaches that have persisted for the past 6 months and states that her current symptoms feel like her previous headaches with a severity of 3/10. She has been prescribed multiple medications but is generally non-compliant with therapy. She is requesting an exam and urgent treatment for her symptoms. Which of the following is the best response from the physician?

A 42-year-old woman presents to the emergency department with abdominal pain. Her pain started last night during dinner and has persisted. This morning, the patient felt very ill and her husband called emergency medical services. The patient has a past medical history of obesity, diabetes, and depression. Her temperature is 104°F (40°C), blood pressure is 90/65 mmHg, pulse is 160/min, respirations are 14/min, and oxygen saturation is 98% on room air. Physical exam is notable for a very ill appearing woman. Her skin is mildly yellow, and she is in an antalgic position on the stretcher. Laboratory values are ordered as seen below. Hemoglobin: 13 g/dL Hematocrit: 38% Leukocyte count: 14,500 cells/mm^3 with normal differential Platelet count: 257,000/mm^3 Alkaline phosphatase: 227 U/L Bilirubin, total: 11.3 mg/dL Bilirubin, direct: 9.8 mg/dL AST: 42 U/L ALT: 31 U/L The patient is started on antibiotics and IV fluids. Which of the following is the best next step in management?

A 51-year-old man with a recent diagnosis of peptic ulcer disease currently treated with an oral proton pump inhibitor twice daily presents to the urgent care center complaining of acute abdominal pain which began suddenly less than 2 hours ago. On physical exam, you find his abdomen to be mildly distended, diffusely tender to palpation, and positive for rebound tenderness. Given the following options, what is the next best step in patient management?

A 67-year-old man presents to the emergency department for squeezing and substernal chest pain. He states that he was at home eating dinner when his symptoms began. The patient has a past medical history of diabetes, hypertension, and dyslipidemia. He is currently taking atorvastatin, lisinopril, insulin, metformin, metoprolol, and aspirin. Six days ago he underwent percutaneous coronary intervention. His temperature is 99.5°F (37.5°C), blood pressure is 197/118 mmHg, pulse is 120/min, respirations are 17/min, and oxygen saturation is 98% on room air. Physical exam reveals an uncomfortable elderly man who is sweating. An ECG is ordered. Which of the following is the best next step in management for this patient?

An orthopaedic surgeon at a local community hospital has noticed that turnover times in the operating room have been unnecessarily long. She believes that the long wait times may be due to inefficient communication between the surgical nursing staff, the staff in the pre-operative area, and the staff in the post-operative receiving area. She believes a secure communication mobile phone app would help to streamline communication between providers and improve efficiency in turnover times. Which of the following methods is most appropriate to evaluate the impact of this intervention in the clinical setting?

A 65-year-old man is admitted to the hospital because of a 1-month history of fatigue, intermittent fever, and weakness. Results from a peripheral blood smear taken during his evaluation are indicative of possible acute myeloid leukemia. Bone marrow aspiration and subsequent cytogenetic studies confirm the diagnosis. The physician sets aside an appointed time-slot and arranges a meeting in a quiet office to inform him about the diagnosis and discuss his options. He has been encouraged to bring someone along to the appointment if he wanted. He comes to your office at the appointed time with his daughter. He appears relaxed, with a full range of affect. Which of the following is the most appropriate opening statement in this situation?

Question 1: A 40-year-old woman presents to her physician's home with a headache. She describes it as severe and states that her symptoms have not been improving despite her appointment yesterday at the office. Thus, she came to her physician's house on the weekend for help. The patient has been diagnosed with migraine headaches that have persisted for the past 6 months and states that her current symptoms feel like her previous headaches with a severity of 3/10. She has been prescribed multiple medications but is generally non-compliant with therapy. She is requesting an exam and urgent treatment for her symptoms. Which of the following is the best response from the physician?

A. It sounds to me like you are in a lot of pain. Let me see how I can help you.
B. Do not come to my house when you have medical problems. You should make an appointment.
C. Your symptoms seem severe. Let me perform a quick exam to see if everything is alright.
D. Unfortunately, I cannot examine and treat you at this time. Please set up an appointment to see me in my office. (Correct Answer)
E. You should go to the emergency department for your symptoms rather than coming here.

Explanation: ***Unfortunately, I cannot examine and treat you at this time. Please set up an appointment to see me in my office.*** - This response appropriately **maintains professional boundaries** by declining an unscheduled visit to the physician's private residence. - While house calls are not inherently unethical, this situation is problematic because: the physician is unprepared, lacks proper medical equipment and documentation resources at home, and the patient's symptoms (3/10 severity, chronic migraine) do not constitute an emergency. - This response is **empathetic yet firm**, redirecting the patient to appropriate care settings where proper examination, documentation, and treatment can occur. - Setting this boundary prevents establishing an inappropriate precedent for future unscheduled home visits. *It sounds to me like you are in a lot of pain. Let me see how I can help you.* - While showing empathy, agreeing to treat the patient at home without preparation creates problems: **lack of proper medical equipment, diagnostic tools, and documentation resources**. - This action **blurs professional boundaries** and sets an inappropriate precedent for future unscheduled patient interactions at the physician's home. - The patient's severity (3/10) and chronic nature of symptoms do not justify an urgent unscheduled home examination. *Do not come to my house when you have medical problems. You should make an appointment.* - This response is **unprofessional and lacks empathy**, potentially damaging the patient-physician relationship. - While the message about boundaries is appropriate, the **harsh tone** fails to provide compassionate guidance for the patient's concerns. *Your symptoms seem severe. Let me perform a quick exam to see if everything is alright.* - Despite acknowledging the patient's concern, performing an unscheduled exam at home is **inappropriate** due to lack of preparation, proper equipment, and resources for thorough assessment. - This decision could lead to **inadequate care and documentation issues**, as the physician would be practicing in an unplanned setting without proper resources. *You should go to the emergency department for your symptoms rather than coming here.* - While this directs the patient to a medical facility, the patient has **3/10 severity** chronic migraine symptoms that do not constitute an emergency, making the ED an **inappropriate over-triage**. - This response may come across as dismissive and could strain the patient-physician relationship, though it does maintain appropriate boundaries.

Question 2: A 42-year-old woman presents to the emergency department with abdominal pain. Her pain started last night during dinner and has persisted. This morning, the patient felt very ill and her husband called emergency medical services. The patient has a past medical history of obesity, diabetes, and depression. Her temperature is 104°F (40°C), blood pressure is 90/65 mmHg, pulse is 160/min, respirations are 14/min, and oxygen saturation is 98% on room air. Physical exam is notable for a very ill appearing woman. Her skin is mildly yellow, and she is in an antalgic position on the stretcher. Laboratory values are ordered as seen below. Hemoglobin: 13 g/dL Hematocrit: 38% Leukocyte count: 14,500 cells/mm^3 with normal differential Platelet count: 257,000/mm^3 Alkaline phosphatase: 227 U/L Bilirubin, total: 11.3 mg/dL Bilirubin, direct: 9.8 mg/dL AST: 42 U/L ALT: 31 U/L The patient is started on antibiotics and IV fluids. Which of the following is the best next step in management?

A. Nasogastric tube and NPO
B. Supportive therapy followed by elective cholecystectomy
C. FAST exam
D. Emergency cholecystectomy
E. Endoscopic retrograde cholangiopancreatography (Correct Answer)

Explanation: ***Endoscopic retrograde cholangiopancreatography*** - The patient's presentation with **fever**, **jaundice**, **abdominal pain**, **hypotension**, and **tachycardia** (Reynolds' pentad) indicates **acute cholangitis**. - **ERCP** is the best next step for **biliary decompression** and stone extraction in severe obstructive cholangitis to reduce morbidity and mortality. *Nasogastric tube and NPO* - While **NPO** (nothing by mouth) is standard for acute abdominal pain, a **nasogastric tube** is not typically indicated as a primary intervention for cholangitis unless there's associated vomiting or gastric distention. - This step addresses symptoms but does not treat the underlying **biliary obstruction** and infection. *Supportive therapy followed by elective cholecystectomy* - **Supportive therapy** with antibiotics and IV fluids is already initiated but is insufficient for severe cholangitis requiring **urgent biliary drainage**. - **Elective cholecystectomy** is performed after the acute infection has resolved, but not as an immediate intervention for an unstable patient with acute cholangitis. *FAST exam* - A **Focused Assessment with Sonography for Trauma (FAST)** exam is primarily used to detect **free fluid** (hemoperitoneum) in trauma patients. - It is not indicated for the diagnosis or management of **biliary obstruction** or cholangitis in a non-trauma setting. *Emergency cholecystectomy* - **Emergency cholecystectomy** is generally reserved for complications like **gangrenous cholecystitis** or perforation, or after initial stabilization in acute cholecystitis. - For **acute cholangitis**, the priority is **biliary decompression** first, which is typically achieved through ERCP, before considering cholecystectomy.

Question 3: A 51-year-old man with a recent diagnosis of peptic ulcer disease currently treated with an oral proton pump inhibitor twice daily presents to the urgent care center complaining of acute abdominal pain which began suddenly less than 2 hours ago. On physical exam, you find his abdomen to be mildly distended, diffusely tender to palpation, and positive for rebound tenderness. Given the following options, what is the next best step in patient management?

A. Serum gastrin level
B. Urgent CT abdomen and pelvis (Correct Answer)
C. H. pylori testing
D. Abdominal radiographs
E. Upper endoscopy

Explanation: ***Urgent CT abdomen and pelvis*** - The sudden onset of severe abdominal pain, diffuse tenderness, and **rebound tenderness** in a patient with a history of peptic ulcer disease (PUD) suggests a **perforated ulcer**, which is a surgical emergency. - A CT scan is the **most sensitive imaging modality** for detecting **free air** (pneumoperitoneum) and can confirm the diagnosis with >95% sensitivity, helping to localize the perforation and identify complications such as abscess formation. - CT also helps evaluate alternative diagnoses in the acute abdomen and provides detailed anatomic information for surgical planning. *Serum gastrin level* - This test is primarily used in the diagnosis of **Zollinger-Ellison syndrome**, a rare condition characterized by gastrinomas leading to severe, refractory PUD. - It is not indicated in an acute emergency setting with signs of perforation, as it would delay critical diagnostic imaging and management. *H. pylori testing* - **_H. pylori_ infection** is a common cause of PUD, but testing for it is part of routine initial management or follow-up for chronic disease. - Testing would not address the immediate life-threatening complication of suspected perforation and would delay definitive diagnosis. *Abdominal radiographs* - An upright chest X-ray or abdominal radiograph can detect **free air under the diaphragm** in cases of perforation and is a reasonable initial imaging test. - However, plain radiographs have lower sensitivity (75-80%) compared to CT scan and may miss smaller perforations or provide insufficient information about the location and extent of injury. - In modern practice with readily available CT, cross-sectional imaging is preferred for its superior diagnostic accuracy in evaluating the acute abdomen. *Upper endoscopy* - **Upper endoscopy** is a valuable diagnostic and therapeutic tool for stable PUD but is **absolutely contraindicated** in cases of suspected or confirmed hollow viscus perforation. - Introducing an endoscope with air insufflation could worsen the perforation and lead to further contamination of the peritoneal cavity, increasing morbidity and mortality.

Question 4: A 67-year-old man presents to the emergency department for squeezing and substernal chest pain. He states that he was at home eating dinner when his symptoms began. The patient has a past medical history of diabetes, hypertension, and dyslipidemia. He is currently taking atorvastatin, lisinopril, insulin, metformin, metoprolol, and aspirin. Six days ago he underwent percutaneous coronary intervention. His temperature is 99.5°F (37.5°C), blood pressure is 197/118 mmHg, pulse is 120/min, respirations are 17/min, and oxygen saturation is 98% on room air. Physical exam reveals an uncomfortable elderly man who is sweating. An ECG is ordered. Which of the following is the best next step in management for this patient?

A. Stress testing
B. Angiography (Correct Answer)
C. Cardiac troponins
D. Creatine kinase-MB
E. Myoglobin

Explanation: ***Correct: Angiography*** - This patient presenting with **acute chest pain 6 days post-PCI** is at high risk for **stent thrombosis or acute in-stent restenosis**, which represents a life-threatening emergency. - Given the **clinical instability** (severe hypertension 197/118, tachycardia 120/min, diaphoresis) and classic ACS symptoms in the immediate post-PCI period, **urgent coronary angiography** is the best next step in management. - While ECG and troponins are important diagnostic tools, this patient requires **immediate intervention** to evaluate the recent PCI site and potentially perform emergent revascularization. - In the setting of suspected **acute stent thrombosis**, time to reperfusion is critical, and angiography allows both diagnosis and treatment. *Incorrect: Cardiac troponins* - While troponins are essential biomarkers for myocardial injury and should be obtained, they are a **diagnostic test** rather than definitive management. - Waiting for troponin results would delay definitive management in a patient with clear clinical evidence of ACS. - In this high-risk post-PCI patient with active symptoms, management should not wait for biomarker confirmation. *Incorrect: Stress testing* - Stress testing is **absolutely contraindicated** in patients with active chest pain and suspected acute MI. - It could precipitate further myocardial ischemia, arrhythmias, or cardiac arrest. - Stress testing is reserved for risk stratification in stable patients or after ACS has been ruled out. *Incorrect: Creatine kinase-MB* - CK-MB is less sensitive and specific than troponins for myocardial injury, as it can be elevated in skeletal muscle conditions. - It has a shorter elevation window and has largely been replaced by troponins in modern practice. - Like troponins, it would not change the immediate management need in this clinically unstable patient. *Incorrect: Myoglobin* - Myoglobin lacks cardiac specificity (present in both cardiac and skeletal muscle) and has poor diagnostic accuracy for MI. - Its rapid rise and fall make it unreliable, and it generates many false positives. - It has no role in guiding management decisions in suspected ACS.

Question 5: An orthopaedic surgeon at a local community hospital has noticed that turnover times in the operating room have been unnecessarily long. She believes that the long wait times may be due to inefficient communication between the surgical nursing staff, the staff in the pre-operative area, and the staff in the post-operative receiving area. She believes a secure communication mobile phone app would help to streamline communication between providers and improve efficiency in turnover times. Which of the following methods is most appropriate to evaluate the impact of this intervention in the clinical setting?

A. Plan-Do-Study-Act cycle (Correct Answer)
B. Failure modes and effects analysis
C. Standardization
D. Forcing function
E. Root cause analysis

Explanation: ***Plan-Do-Study-Act cycle*** - The **Plan-Do-Study-Act (PDSA) cycle** is a structured, iterative model used for continuous improvement in quality and efficiency, making it ideal for evaluating the impact of a new intervention like a communication app. - This cycle allows for small-scale testing of changes, observation of results, learning from the observations, and refinement of the intervention before full implementation. *Failure modes and effects analysis* - **Failure modes and effects analysis (FMEA)** is a prospective method to identify potential failures in a process, predict their effects, and prioritize actions to prevent them. - While useful for process improvement, FMEA is typically performed *before* implementing a change to identify risks, rather than to evaluate the impact of an already implemented intervention. *Standardization* - **Standardization** involves creating and implementing consistent processes or protocols to reduce variability and improve reliability. - While the communication app might contribute to standardization, standardization itself is a *method of improvement* rather than a method for *evaluating the impact* of an intervention. *Forcing function* - A **forcing function** is a design feature that physically prevents an error from occurring, making it impossible to complete a task incorrectly. - An app that streamlines communication does not act as a forcing function, as it facilitates a process rather than physically preventing an incorrect action. *Root cause analysis* - **Root cause analysis (RCA)** is a retrospective method used to investigate an event that has already occurred (e.g., an adverse event) to identify its underlying causes. - This method is used *after* a problem has manifested to understand *why* it happened, not to evaluate the *impact* of a new intervention designed to prevent future problems.

Question 6: A 65-year-old man is admitted to the hospital because of a 1-month history of fatigue, intermittent fever, and weakness. Results from a peripheral blood smear taken during his evaluation are indicative of possible acute myeloid leukemia. Bone marrow aspiration and subsequent cytogenetic studies confirm the diagnosis. The physician sets aside an appointed time-slot and arranges a meeting in a quiet office to inform him about the diagnosis and discuss his options. He has been encouraged to bring someone along to the appointment if he wanted. He comes to your office at the appointed time with his daughter. He appears relaxed, with a full range of affect. Which of the following is the most appropriate opening statement in this situation?

A. Your lab reports show that you have an acute myeloid leukemia
B. What is your understanding of the reasons we did bone marrow aspiration and cytogenetic studies? (Correct Answer)
C. You must be curious and maybe even anxious about the results of your tests.
D. I may need to refer you to a blood cancer specialist because of your diagnosis. You may need chemotherapy or radiotherapy, which we are not equipped for.
E. Would you like to know all the details of your diagnosis, or would you prefer I just explain to you what our options are?

Explanation: ***"What is your understanding of the reasons we did bone marrow aspiration and cytogenetic studies?"*** - This **open-ended question** allows the patient to express their current knowledge and perceptions, which helps the physician tailor the discussion. - It establishes a **patient-centered approach**, respecting the patient's existing understanding and preparing them for further information. *"You must be curious and maybe even anxious about the results of your tests."* - While empathic, this statement makes an **assumption about the patient's feelings** rather than inviting them to share their own. - It is often better to ask directly or use more open-ended questions that allow the patient to express their true emotions, especially given their **relaxed demeanor**. *"I may need to refer you to a blood cancer specialist because of your diagnosis. You may need chemotherapy or radiotherapy, which we are not equipped for.”"* - This statement immediately introduces **overwhelming and potentially alarming information** (referral, chemotherapy, radiotherapy) without first establishing the diagnosis or assessing the patient's readiness to receive it. - It prematurely jumps to treatment and logistics, potentially causing **unnecessary distress** before the patient has processed the core diagnosis. *"Would you like to know all the details of your diagnosis, or would you prefer I just explain to you what our options are?""* - While it attempts to assess the patient's preference for information, this question is a **closed-ended "either/or" choice** that might limit the patient's ability to express nuanced needs. - It also prematurely introduces the idea of "options" without first explaining the diagnosis in an understandable context. *"Your lab reports show that you have an acute myeloid leukemia"* - This is a **direct and blunt delivery of a serious diagnosis** without any preparatory context or assessment of the patient's existing knowledge or emotional state. - Delivering such news abruptly can be shocking and overwhelming, potentially **hindering effective communication** and rapport building.
