Question 1 of 5
Patient presents with CAD and EF 40%. Which treatment improves survival with class I indication for revascularization?
Correct Answer: B
Rationale: For CAD with EF 40%, CABG is a class II indication, as it may improve survival but lacks the stronger class I evidence seen in lower EF ranges (35-50%) or specific anatomic criteria.
Question 2 of 5

Question 4 of 5
A 72 yo male presents with obtundation, a 3 cm mass in his right upper lobe of his lung, dehydration, and a calcium of 16.4 mg/dl. The most likely cause of his hypercalcemia is:
Correct Answer: B
Rationale: Elevated PTHrP is the most likely cause of hypercalcemia in this patient with lung cancer, as it is commonly secreted by malignancies like squamous cell carcinoma.
Question 5 of 5
A 22-y male with cystic fibrosis with F508 del mutation presents for evaluation of worsening shortness of breath, wheezing, and cough productive of dark sputum. He was treated a month ago for similar symptoms with a course of antibiotics and tapering prednisone. Medications include lumacaftor/ivacaftor, inhaled tobramycin and albuterol, along with his usual oral medications. Vital signs are normal. Physical exam is notable for diffuse wheezing bilaterally. WBC count is normal with 15% eosinophils. CXR shows scattered infiltrates. What is the most likely diagnosis?
Correct Answer: C
Rationale: In cystic fibrosis, wheezing, eosinophilia (15%), and infiltrates suggest allergic bronchopulmonary aspergillosis (ABPA), a common complication. Elevated eosinophils and response to prior steroids support this over bacterial infections like Burkholderia or MAC.
