Question 1: A 55-year-old male with type 2 diabetes has a BP of 145/92 mmHg on
three visits. What is the target BP per ACC/AHA guidelines?
A. < 150/90 mmHg B. < 140/90 mmHg C. < 130/80 mmHg D. < 120/70 mmHg
CORRECT ANSWER: C. < 130/80 mmHg
Rationale: ACC/AHA guidelines recommend a BP target of < 130/80 mmHg for patients
with diabetes to reduce cardiovascular risk.
Question 2: A 60-year-old female presents with crushing chest pain radiating to her
jaw. ECG shows ST elevation in leads II, III, and aVF. Which coronary artery is most
likely occluded?
A. Left anterior descending B. Left circumflex C. Right coronary artery D. Left main
coronary
CORRECT ANSWER: C. Right coronary artery
Rationale: ST elevation in leads II, III, and aVF indicates an inferior myocardial infarction,
which is most commonly caused by occlusion of the right coronary artery.
Question 3: Which medication is contraindicated in a patient with heart failure with
reduced ejection fraction (HFrEF) and a history of angioedema?
A. Lisinopril B. Metoprolol succinate C. Spironolactone D. Sacubitril/valsartan
CORRECT ANSWER: A. Lisinopril
Rationale: ACE inhibitors like lisinopril are contraindicated in patients with a history of
angioedema due to the risk of recurrence.
Question 4: A patient with atrial fibrillation has a CHA2DS2-VASc score of 3. What is
the recommended management?
A. Aspirin only B. No antithrombotic therapy C. Oral anticoagulation D. Clopidogrel
CORRECT ANSWER: C. Oral anticoagulation
Rationale: A CHA2DS2-VASc score of 2 or more in men, or 3 or more in women,
indicates a high risk for stroke, warranting oral anticoagulation.
Question 5: Which ECG finding is characteristic of Wolff-Parkinson-White (WPW)
syndrome?
,A. Short PR interval and delta wave B. Prolonged QT interval C. ST segment elevation D.
Deep Q waves
CORRECT ANSWER: A. Short PR interval and delta wave
Rationale: WPW syndrome is characterized by a short PR interval, a widened QRS
complex, and a slurred upstroke of the QRS known as a delta wave.
Question 6: A 45-year-old male presents with a tearing chest pain radiating to the
back. BP is 190/110 mmHg in the right arm and 160/90 mmHg in the left. What is the
most likely diagnosis?
A. Myocardial infarction B. Aortic dissection C. Pulmonary embolism D. Esophageal
rupture
CORRECT ANSWER: B. Aortic dissection
Rationale: Tearing chest pain radiating to the back with asymmetric blood pressures in
the arms is highly suggestive of an aortic dissection.
Question 7: Which class of antihypertensive medications is first-line for a patient
with hypertension and benign prostatic hyperplasia (BPH)?
A. ACE inhibitors B. Beta-blockers C. Alpha-1 blockers D. Calcium channel blockers
CORRECT ANSWER: C. Alpha-1 blockers
Rationale: Alpha-1 blockers, such as doxazosin or terazosin, treat both hypertension
and BPH symptoms by relaxing smooth muscle in the blood vessels and prostate.
Question 8: A patient taking digoxin presents with nausea, vomiting, and visual
changes (yellow halos). What is the most likely cause?
A. Hypokalemia B. Digoxin toxicity C. Hypercalcemia D. Renal failure
CORRECT ANSWER: B. Digoxin toxicity
Rationale: Nausea, vomiting, and visual disturbances like yellow-green halos are
classic signs of digoxin toxicity.
Question 9: Which lipid-lowering medication works by inhibiting HMG-CoA
reductase?
A. Ezetimibe B. Atorvastatin C. Fenofibrate D. Niacin
CORRECT ANSWER: B. Atorvastatin
Rationale: Statins, such as atorvastatin, lower cholesterol by competitively inhibiting
HMG-CoA reductase, the rate-limiting enzyme in cholesterol synthesis.
Question 10: A 65-year-old male with a history of MI is prescribed a beta-blocker.
Which of the following is a common adverse effect of non-selective beta-blockers?
A. Hypokalemia B. Bronchospasm C. Hyperglycemia D. Tachycardia
,CORRECT ANSWER: B. Bronchospasm
Rationale: Non-selective beta-blockers block beta-2 receptors in the lungs, which can
cause bronchoconstriction and bronchospasm, especially in patients with asthma or
COPD.
Question 11: A patient presents with a dry, hacking cough that started after
beginning a new antihypertensive medication. Which drug is the most likely
culprit?
A. Amlodipine B. Losartan C. Lisinopril D. Hydrochlorothiazide
CORRECT ANSWER: C. Lisinopril
Rationale: ACE inhibitors like lisinopril can cause a dry cough due to the accumulation
of bradykinin in the lungs.
Question 12: What is the primary mechanism of action of nitroglycerin in the
treatment of angina?
A. Increases heart rate B. Decreases myocardial oxygen demand via venodilation C.
Increases myocardial contractility D. Blocks calcium channels
CORRECT ANSWER: B. Decreases myocardial oxygen demand via venodilation
Rationale: Nitroglycerin primarily causes venodilation, which reduces preload and
subsequently decreases myocardial oxygen demand.
Question 13: A 30-year-old female presents with palpitations, weight loss, and heat
intolerance. Labs show suppressed TSH and elevated free T4. What is the most
likely diagnosis?
A. Hashimoto's thyroiditis B. Graves' disease C. Subacute thyroiditis D. Thyroid cancer
CORRECT ANSWER: B. Graves' disease
Rationale: Symptoms of hyperthyroidism with suppressed TSH and elevated free T4
indicate primary hyperthyroidism, most commonly caused by Graves' disease in young
females.
Question 14: Which finding on physical exam is specific to Graves' disease?
A. Cold, dry skin B. Exophthalmos C. Delayed deep tendon reflexes D. Bradycardia
CORRECT ANSWER: B. Exophthalmos
Rationale: Exophthalmos (proptosis) is a classic and specific sign of Graves' disease,
caused by autoimmune infiltration of the extraocular muscles and orbital fat.
Question 15: A patient with type 1 diabetes presents with Kussmaul respirations,
fruity breath odor, and a blood glucose of 450 mg/dL. What is the primary
treatment?
, A. Oral hypoglycemics B. IV fluids and regular insulin C. Subcutaneous glargine insulin
D. IV glucagon
CORRECT ANSWER: B. IV fluids and regular insulin
Rationale: Diabetic ketoacidosis (DKA) is treated with aggressive IV fluid resuscitation
and a continuous IV infusion of regular insulin.
Question 16: Which oral antidiabetic medication carries a black box warning for
causing or exacerbating heart failure?
A. Metformin B. Pioglitazone C. Sitagliptin D. Glipizide
CORRECT ANSWER: B. Pioglitazone
Rationale: Thiazolidinediones like pioglitazone cause fluid retention and carry a black
box warning for causing or exacerbating congestive heart failure.
Question 17: A 50-year-old female presents with fatigue, weight gain, and cold
intolerance. TSH is elevated and free T4 is low. What is the most likely diagnosis?
A. Primary hyperthyroidism B. Primary hypothyroidism C. Secondary hypothyroidism D.
Subclinical hypothyroidism
CORRECT ANSWER: B. Primary hypothyroidism
Rationale: An elevated TSH with a low free T4 indicates primary hypothyroidism, where
the thyroid gland fails to produce adequate thyroid hormones.
Question 18: Which medication should be avoided in a patient with a history of
medullary thyroid cancer?
A. Metformin B. Liraglutide C. Glipizide D. Acarbose
CORRECT ANSWER: B. Liraglutide
Rationale: GLP-1 receptor agonists like liraglutide carry a black box warning and are
contraindicated in patients with a personal or family history of medullary thyroid
carcinoma or MEN 2.
Question 19: A patient with type 2 diabetes and chronic kidney disease (eGFR 35
mL/min) would benefit most from which medication to slow CKD progression?
A. Glipizide B. Empagliflozin C. Pioglitazone D. Sitagliptin
CORRECT ANSWER: B. Empagliflozin
Rationale: SGLT2 inhibitors like empagliflozin have been shown to significantly slow the
progression of chronic kidney disease and reduce cardiovascular events in patients with
diabetes and CKD.
Question 20: Which laboratory test is most appropriate for monitoring long-term
glycemic control in a patient with diabetes?
