Cardiovascular & Hematologic Pharmacology
1. A 62-year-old African American male with hypertension and stage 3
chronic kidney disease (CKD) presents for follow-up. His BP is 148/90
mmHg. Which antihypertensive regimen is MOST appropriate as first-
line therapy given his comorbid conditions?
• A) Hydrochlorothiazide 25 mg daily
• B) Lisinopril 10 mg daily
• C) Metoprolol 50 mg daily
• D) Amlodipine 5 mg daily
Correct Answer: B
Rationale: ACE inhibitors (like lisinopril) are first-line for
hypertension, especially in patients with CKD due to their
renoprotective effects (reducing intraglomerular pressure). While
thiazides are first-line for general HTN, they are less effective in
advanced CKD (eGFR <30). Beta-blockers are not first-line without
another compelling indication. CCBs are options but do not provide the
same renal protection as RAAS blockade.
2. A patient with non-valvular atrial fibrillation (CHADS-VASc score of
4) is currently taking warfarin. He asks about switching to apixaban
,(Eliquis) to avoid dietary restrictions. What is a primary advantage of
apixaban over warfarin?
• A) No requirement for routine INR monitoring
• B) Reversal agent is widely available over-the-counter
• C) Lower cost than warfarin
• D) Safe to use in mechanical heart valves
Correct Answer: A
Rationale: Direct Oral Anticoagulants (DOACs) like apixaban have
predictable pharmacokinetics and do not require routine INR
monitoring. DOACs are contraindicated in mechanical heart valves.
Vitamin K is the reversal agent for warfarin; andexanet alfa is expensive
and used for specific DOACs. Warfarin is generally much cheaper.
3. Which medication is associated with the adverse effect of a persistent,
dry, hacking cough that resolves upon discontinuation?
• A) Losartan
• B) Lisinopril
• C) Metoprolol
• D) Amlodipine
Correct Answer: B
Rationale: Angiotensin-converting enzyme (ACE) inhibitors (lisinopril,
enalapril) commonly cause a dry cough due to the accumulation of
bradykinin in the lungs. ARBs (losartan) have a significantly lower
incidence of cough. Beta-blockers cause fatigue/bradycardia; CCBs
cause edema.
,4. A patient is prescribed furosemide (Lasix) 40 mg BID for heart
failure. Which laboratory finding requires the most immediate
intervention?
• A) Sodium 135 mEq/L
• B) Creatinine 1.1 mg/dL
• C) Potassium 2.9 mEq/L
• D) BUN 18 mg/dL
Correct Answer: C
Rationale: Loop diuretics cause significant renal excretion of
potassium, leading to hypokalemia. A potassium of 2.9 mEq/L increases
the risk of fatal cardiac arrhythmias (especially if the patient is also on
digoxin) and requires immediate repletion.
5. A patient on Digoxin presents with nausea, vomiting, blurred vision
(yellow halos), and a heart rate of 45 bpm. Which electrolyte imbalance
most likely precipitated this toxicity?
• A) Hypernatremia
• B) Hypokalemia
• C) Hypercalcemia
• D) Hypomagnesemia
Correct Answer: B
Rationale: Hypokalemia increases the binding of digoxin to the sodium-
potassium ATPase pump, leading to toxicity even at normal serum
levels. Low potassium enhances the toxic effects of digoxin on cardiac
conduction and automaticity.
, 6. Which of the following is the antidote of choice for a patient with life-
threatening bleeding due to apixaban (Eliquis)?
• A) Protamine Sulfate
• B) Vitamin K
• C) Andexanet alfa
• D) Naloxone
Correct Answer: C
Rationale: Andexanet alfa (Andexxa) is a recombinant modified human
factor Xa decoy protein that binds and sequesters apixaban and
rivaroxaban. Protamine reverses heparin. Vitamin K reverses warfarin.
Respiratory & Immunology
7. According to the 2026 GINA guidelines, what is the preferred reliever
medication for an adult with mild intermittent asthma?
• A) Low-dose ICS-formoterol (as needed)
• B) Albuterol (SABA) as needed
• C) Oral montelukast daily
• D) High-dose ICS daily
Correct Answer: B
Rationale: While guidelines are shifting toward ICS-formoterol for mild
persistent asthma, for intermittent asthma (symptoms <2 days/week),
as-needed short-acting beta-agonist (SABA) such as albuterol remains
the standard rescue therapy. However, the search results emphasize that
for persistent asthma, ICS-formoterol is preferred to reduce severe
exacerbations.
