1. A patient taking lisinopril should be monitored for which electrolyte
imbalance?
A. Hypernatremia
B. Hyperkalemia
C. Hypokalemia
D. Hypocalcemia
ACE inhibitors decrease aldosterone, leading to potassium retention and risk of
hyperkalemia.
2. Which medication requires peak and trough level monitoring?
A. Ibuprofen
B. Metformin
C. Vancomycin
D. Amlodipine
Vancomycin has a narrow therapeutic range and requires monitoring to
prevent toxicity.
3. A patient on warfarin should have which lab monitored regularly?
A. aPTT
B. Platelet count
C. INR
D. Hemoglobin A1c
INR evaluates warfarin effectiveness and bleeding risk.
4. Which side effect is common with opioid therapy?
,A. Diarrhea
B. Hypertension
C. Constipation
D. Tachycardia
Opioids decrease GI motility, commonly causing constipation.
5. The antidote for acetaminophen overdose is:
A. Flumazenil
B. Naloxone
C. Protamine
D. Acetylcysteine
Acetylcysteine replenishes glutathione and prevents liver damage.
6. Which medication should be taken with food to reduce GI irritation?
A. Levothyroxine
B. NSAIDs
C. Alendronate
D. Sucralfate
NSAIDs can irritate the stomach lining and should be taken with food.
7. A patient taking digoxin should be monitored for:
A. Hyperglycemia
B. Bradycardia
C. Hypertension
D. Hypernatremia
Digoxin slows heart rate; bradycardia may indicate toxicity.
8. Which lab value indicates therapeutic heparin therapy?
A. INR 2–3
B. Platelets >400,000
C. aPTT 1.5–2.5 times control
, D. Hemoglobin >15
Heparin effectiveness is monitored using aPTT.
9. The antidote for opioid overdose is:
A. Flumazenil
B. Naloxone
C. Vitamin K
D. Atropine
Naloxone reverses opioid effects by displacing them from receptors.
10. Which medication class commonly causes a dry cough?
A. Beta blockers
B. Calcium channel blockers
C. ACE inhibitors
D. Diuretics
ACE inhibitors increase bradykinin, leading to a persistent cough.
11. Which drug should be held if potassium is 5.8 mEq/L?
A. Furosemide
B. Spironolactone
C. Hydrochlorothiazide
D. Metoprolol
Spironolactone is potassium-sparing and can worsen hyperkalemia.
12. Metformin should be held prior to:
A. Surgery only
B. Blood transfusion
C. IV contrast studies
D. Vaccination
Metformin increases risk of lactic acidosis with contrast dye.
