ADVANCED PATHOPHYSIOLOGY, PHARMACOLOGY &
ASSESSMENT
1. A 65-year-old patient with heart failure presents with dyspnea, orthopnea,
and bilateral crackles. Which medication is most appropriate for acute
symptom relief?
A. Lisinopril
B. Furosemide
C. Metoprolol
D. Digoxin
Correct Answer: B. Furosemide
Rationale: Loop diuretics like furosemide reduce fluid overload and provide rapid
symptom relief in acute heart failure exacerbation.
2. A patient taking ACE inhibitors develops a persistent dry cough. What is the
best alternative?
,A. Amlodipine
B. Losartan
C. Hydrochlorothiazide
D. Atenolol
Correct Answer: B. Losartan
Rationale: ARBs like losartan are used when ACE inhibitors cause cough due to
bradykinin accumulation.
3. Which lab finding is most consistent with diabetic ketoacidosis?
A. Hypoglycemia
B. Metabolic alkalosis
C. Anion gap metabolic acidosis
D. Respiratory acidosis
Correct Answer: C. Anion gap metabolic acidosis
Rationale: DKA causes ketone accumulation leading to high anion gap metabolic
acidosis.
4. Which medication is contraindicated in pregnancy?
A. Amoxicillin
B. Methotrexate
C. Prenatal vitamins
D. Cephalexin
Correct Answer: B. Methotrexate
Rationale: Methotrexate is teratogenic and contraindicated in pregnancy due to
fetal toxicity.
5. A patient presents with wheezing, hypotension, and urticaria after a bee
sting. First-line treatment?
,A. Diphenhydramine
B. Epinephrine IM
C. Albuterol
D. Prednisone
Correct Answer: B. Epinephrine IM
Rationale: Epinephrine is first-line for anaphylaxis due to rapid reversal of
airway and vascular compromise.
CARDIOVASCULAR SYSTEM
6. Which ECG finding is consistent with acute myocardial infarction?
A. PR prolongation
B. ST elevation
C. U waves
D. QT shortening
Correct Answer: B. ST elevation
Rationale: ST elevation indicates acute transmural myocardial injury.
7. First-line therapy for stable angina?
A. Nitroglycerin
B. Aspirin only
C. Morphine
D. Atropine
Correct Answer: A. Nitroglycerin
Rationale: Nitroglycerin relieves angina by reducing myocardial oxygen demand.
8. Which condition increases risk for atrial fibrillation?
, A. Hypothyroidism
B. Hypertension
C. Hypokalemia only
D. Hypercalcemia
Correct Answer: B. Hypertension
Rationale: Hypertension leads to atrial remodeling and increased AF risk.
9. A patient with AFib should be anticoagulated based on:
A. CHADS2-VASc score
B. APGAR score
C. Wells score
D. Glasgow score
Correct Answer: A. CHADS2-VASc score
Rationale: This score determines stroke risk in atrial fibrillation patients.
10.Which drug class reduces mortality in heart failure?
A. Calcium channel blockers
B. ACE inhibitors
C. NSAIDs
D. Antihistamines
Correct Answer: B. ACE inhibitors
Rationale: ACE inhibitors reduce afterload and improve survival in heart failure.
RESPIRATORY SYSTEM
11.Most common cause of COPD?
