QUESTION 1
A 65-year-old patient with heart failure with reduced ejection fraction
(HFrEF) is currently on Lisinopril and Furosemide. The addition of which
medication has been shown to further reduce mortality in this
population?
A. Digoxin
B. Metoprolol succinate
C. Diltiazem
D. Verapamil
ANSWER: B. Metoprolol succinate. Beta-blockers such as metoprolol
succinate, bisoprolol, and carvedilol have demonstrated a mortality
benefit in HFrEF. Digoxin reduces hospitalizations but not overall
mortality, and non-dihydropyridine calcium channel blockers like
diltiazem and verapamil have negative inotropic effects that can
worsen heart failure.

Which type of insulin is characteristically cloudy and requires gentle
rolling prior to administration to resuspend the active ingredient?
A. Insulin Glargine
B. Insulin Aspart
C. NPH Insulin
D. Insulin Lispro
ANSWER: C. NPH Insulin. NPH is a suspension of zinc insulin crystals
with protamine, which gives it a cloudy appearance. The other options
are rapid-acting or long-acting insulin analogs that form clear solutions.
QUESTION 3
A patient is started on Warfarin for atrial fibrillation. Which laboratory
value is used to monitor the therapeutic effect and guide dosing?
A. Activated Partial Thromboplastin Time (aPTT)
B. Platelet count
C. International Normalized Ratio (INR)
D. Bleeding time
ANSWER: C. International Normalized Ratio (INR). Warfarin’s effect on
vitamin K-dependent clotting factors is measured by the prothrombin
time, standardized internationally as the INR. The aPTT is used to
monitor unfractionated heparin therapy.

A patient presents with tinnitus, hyperventilation, and respiratory
alkalosis after an intentional overdose. Which medication is the most
likely culprit?
A. Acetaminophen
B. Ibuprofen
C. Aspirin
D. Morphine
ANSWER: C. Aspirin. Salicylate poisoning directly stimulates the
medullary respiratory center, causing hyperventilation and primary
respiratory alkalosis, along with tinnitus. Acetaminophen overdose
leads to hepatotoxicity, while ibuprofen overdose typically causes GI
symptoms and metabolic acidosis.
QUESTION 5
A patient presents to the emergency department with acute severe
hypertension and confusion. Which medication is contraindicated
because it can increase intracranial pressure?
A. Labetalol
B. Nitroprusside
C. Sodium nitroprusside
D. Hydralazine
ANSWER: D. Hydralazine. Direct arteriolar vasodilators such as
hydralazine and sodium nitroprusside can dilate cerebral vasculature
and reflexively increase intracranial pressure. Labetalol, a combined

alpha- and beta-blocker, preserves cerebral autoregulation and is safer
in such settings.
QUESTION 6
Flumazenil is a specific reversal agent used for overdose of which class
of medications?
A. Opioids
B. Benzodiazepines
C. Barbiturates
D. Antipsychotics
ANSWER: B. Benzodiazepines. Flumazenil competitively antagonizes the
benzodiazepine binding site on the GABA-A receptor. Naloxone
reverses opioids, and there is no direct reversal agent for barbiturates
or antipsychotics.
QUESTION 7
Which antidiabetic medication carries a boxed warning for lactic
acidosis, making it contraindicated in patients with significant renal
impairment?
A. Glipizide
B. Sitagliptin
C. Metformin
D. Pioglitazone
