The lesion is pearly with visible telangiectasia and a central ulceration. What is the most appropriate initial management for this lesion? - A\) Cryotherapy - B\) Mohs micrographic surgery - C\) Topical chemotherapy - D\) Electrodesiccation and curettage\ **Correct Answer**: B) Mohs micrographic surgery\ **Educational Objective**: Determine the appropriate initial treatment for basal cell carcinoma with high-risk features.\ **Rationale**: Mohs micrographic surgery is the preferred treatment for basal cell carcinoma, especially on the face and other high-risk areas, due to its high cure rate and ability to preserve healthy tissue. Cryotherapy and topical chemotherapy are generally reserved for superficial basal cell carcinomas, and electrodesiccation and curettage are less suitable for nodular forms. 3. **Atopic Dermatitis Case**\ **Question**: A 5-year-old child presents with pruritic, erythematous lesions on the flexural surfaces of the arms and legs, as well as on the face. The child has a history of asthma and allergic rhinitis. What is the most appropriate first-line treatment for managing this child's atopic dermatitis? - A\) Topical calcineurin inhibitors - B\) Systemic corticosteroids - C\) Topical emollients and corticosteroids - D\) Antihistamines\ **Correct Answer**: C) Topical emollients and corticosteroids\ **Educational Objective**: Understand the first-line treatment for atopic dermatitis in children.\ **Rationale**: The first-line treatment for atopic dermatitis includes topical emollients to maintain skin hydration and topical corticosteroids to manage inflammation. Topical calcineurin inhibitors can be used in cases that are resistant to corticosteroids, but they are not the first choice. Systemic corticosteroids and antihistamines are not typically used as initial treatments for atopic dermatitis. **Anesthesia Questions** 1. **General Anesthesia Case**\ **Question**: A 45-year-old patient undergoing elective surgery has a history of hypertension and is currently taking medication for it. The anesthesiologist plans to administer general anesthesia. Which of the following is a key consideration to minimize the risk of perioperative cardiovascular complications? - A\) Avoid using nitrous oxide - B\) Monitor blood pressure continuously during the procedure - C\) Use only local anesthesia instead of general anesthesia - D\) Administer preoperative antibiotics\ **Correct Answer**: B) Monitor blood pressure continuously during the procedure\ **Educational Objective**: Understand the importance of continuous blood pressure monitoring in patients with a history of hypertension undergoing general anesthesia.\ **Rationale**: Continuous blood pressure monitoring is crucial for managing cardiovascular risks in patients with hypertension undergoing general anesthesia, allowing for prompt adjustments in anesthesia and medication to maintain hemodynamic stability. 2. **Regional Anesthesia Case**\ **Question**: A patient undergoing a lower abdominal surgery is planned for a spinal block. The anesthesiologist needs to ensure that the block is effective. Which of the following tests can be used to assess the adequacy of the spinal anesthesia? - A\) Sensory level testing with a pinprick - B\) Measurement of end-tidal CO2 - C\) Assessment of heart rate variability - D\) Evaluation of intraoperative urine output\ **Correct Answer**: A) Sensory level testing with a pinprick\ **Educational Objective**: Recognize the appropriate test to evaluate the effectiveness of spinal anesthesia.\ **Rationale**: Sensory level testing with a pinprick is used to assess the extent of sensory blockade achieved by a spinal block, ensuring that the anesthesia covers the intended dermatomes for the surgery. Other tests are not used to evaluate the sensory effects of regional anesthesia. 3. **Postoperative Pain Management Case**\ **Question**: A patient reports severe pain following a major abdominal surgery despite receiving a patient-controlled analgesia (PCA) pump with morphine. What is the most appropriate next step in managing this patient's pain? - A\) Increase the dose of morphine in the PCA pump - B\) Switch to oral acetaminophen - C\) Add a non-opioid adjunct, such as a local anesthetic or NSAID - D\) Recommend physical therapy for pain relief\ **Correct Answer**: C) Add a non-opioid adjunct, such as a local anesthetic or NSAID\ **Educational Objective**: Understand the role of adjunctive therapies in managing severe postoperative pain.\ **Rationale**: Adding a non-opioid adjunct, such as a local anesthetic or NSAID, can provide additional pain relief and reduce opioid consumption, improving overall pain management. Simply increasing the opioid dose or switching to acetaminophen may not be sufficient for managing severe pain, and physical therapy is typically not an immediate solution for acute postoperative pain. **Multisystem Questions** 1. **Sepsis and Organ Dysfunction Case**\ **Question**: A 65-year-old diabetic patient is admitted to the ICU with fever, hypotension, and confusion. Laboratory results show elevated lactate levels and renal impairment. Which of the following interventions is most critical in the early management of sepsis? - A\) Administer broad-spectrum antibiotics - B\) Initiate high-dose insulin therapy - C\) Perform urgent dialysis - D\) Start vasopressor therapy immediately\ **Correct Answer**: A) Administer broad-spectrum antibiotics\ **Educational Objective**: Recognize the importance of early antibiotic administration in the management of sepsis.\ **Rationale**: Administering broad-spectrum antibiotics is a critical initial step in the management of sepsis to address the underlying infection. Vasopressors and insulin therapy may be necessary later depending on the patient\'s response and other conditions, but antibiotics are crucial for controlling the infection. 2. **Autoimmune Disorder Case**\ **Question**: A 40-year-old woman presents with joint pain, skin rash, and persistent fever. She also reports fatigue and recent weight loss. Laboratory tests show elevated antinuclear antibodies (ANA) and anti-double-stranded DNA antibodies. What is the most likely diagnosis? - A\) Rheumatoid arthritis - B\) Systemic lupus erythematosus (SLE) - C\) Sjögren\'s syndrome - D\) Dermatomyositis\ **Correct Answer**: B) Systemic lupus erythematosus (SLE)\ **Educational Objective**: Identify the most likely diagnosis based on clinical presentation and laboratory findings.\ **Rationale**: The combination of joint pain, skin rash, fever, and elevated ANA and anti-double-stranded DNA antibodies is characteristic of systemic lupus erythematosus (SLE). Other conditions such as rheumatoid arthritis and Sjögren\'s syndrome have different clinical and serological profiles. 3. **Metabolic Syndrome Case**\ **Question**: A 50-year-old male patient with a history of hypertension, diabetes, and obesity presents with symptoms of intermittent claudication. His physical examination shows diminished pulses in the lower extremities. Which of the following conditions is he at increased risk for? - A\) Coronary artery disease - B\) Hyperthyroidism - C\) Osteoporosis - D\) Pulmonary embolism\ **Correct Answer**: A) Coronary artery disease\ **Educational Objective**: Understand the increased risk of coronary artery disease in patients with metabolic syndrome.\ **Rationale**: Metabolic syndrome, characterized by hypertension, diabetes, and obesity, significantly increases the risk of coronary artery disease. Intermittent claudication indicates peripheral arterial disease, which is also associated with a higher risk of cardiovascular events. 4. **Endocrine and Cardiovascular Case**\ **Question**: A 60-year-old patient with well-controlled diabetes and hypertension presents with sudden onset of chest pain and shortness of breath. The ECG shows ST elevation in the inferior leads. What is the most appropriate initial diagnostic test to assess for myocardial infarction? - A\) Echocardiography - B\) Cardiac troponin levels - C\) Chest X-ray - D\) Complete blood count (CBC)\ **Correct Answer**: B) Cardiac troponin levels\ **Educational Objective**: Identify the key diagnostic test for myocardial infarction.\ **Rationale**: Cardiac troponin levels are crucial for diagnosing myocardial infarction as they are specific markers of cardiac muscle injury. While an ECG can suggest myocardial infarction, troponin levels provide definitive confirmation. Other tests such as echocardiography and chest X-ray are used for further evaluation but not for initial diagnosis. 5. **Gastrointestinal and Renal Case**\ **Question**: A 55-year-old patient with a history of chronic alcohol use presents with abdominal pain, jaundice, and elevated bilirubin levels. He also has ascites and renal impairment. What is the most likely diagnosis? - A\) Hepatic cirrhosis - B\) Acute pancreatitis - C\) Chronic kidney disease - D\) Hepatitis B infection\ **Correct Answer**: A) Hepatic cirrhosis\ **Educational Objective**: Recognize the signs and symptoms of hepatic cirrhosis and its complications.\ **Rationale**: Hepatic cirrhosis due to chronic alcohol use commonly presents with abdominal pain, jaundice, ascites, and renal impairment (hepatorenal syndrome). Acute pancreatitis and hepatitis B infection could present similarly but would require additional clinical and laboratory evidence for confirmation.
