Rationale: Lisinopril, an ACE inhibitor, blocks angiotensin II formation, reducing blood
pressure.
Question 2: A patient is prescribed warfarin. What is the priority nursing assessment?
A) Blood glucose levels
B) INR levels
C) Platelet count
D) Hemoglobin A1c
Rationale: Warfarin requires INR monitoring to assess anticoagulation effectiveness.
,Question 3: What is a common adverse effect of metformin?
A) Hypertension
B) Gastrointestinal upset
C) Hyperkalemia
D) Bradycardia
Rationale: Metformin commonly causes GI side effects like nausea and diarrhea.
Question 4: A patient receives 10 units of regular insulin. When should the nurse expect the
peak effect?
A) 30 minutes
B) 2–4 hours
C) 6–8 hours
D) 12 hours
Rationale: Regular insulin peaks at 2–4 hours post-administration.
Question 5: What is the antidote for heparin overdose?
A) Vitamin K
B) Protamine sulfate
C) Naloxone
D) Flumazenil
Rationale: Protamine sulfate reverses heparin’s anticoagulant effects.
Question 6: A patient on morphine reports constipation. What should the nurse recommend?
A) Increase opioid dose
B) Stool softener or laxative
C) Discontinue morphine
D) Monitor without intervention
Rationale: Opioids cause constipation, requiring a stool softener or laxative.
Question 7: What is the therapeutic use of albuterol?
A) Pain relief
B) Bronchodilation for asthma
C) Blood pressure control
D) Blood glucose management
Rationale: Albuterol, a beta-2 agonist, relieves bronchospasm in asthma.
Question 8: A patient is prescribed fluoxetine. What should the nurse monitor for?
A) Hypoglycemia
B) Serotonin syndrome
C) Hyperkalemia
D) Hypotension
Rationale: Fluoxetine, an SSRI, can cause serotonin syndrome with overdose or interactions.
Question 9: How many mL should a nurse administer for a 500 mg dose of medication if the
concentration is 250 mg/mL?
A) 1 mL
B) 2 mL
C) 3 mL
D) 4 mL
Rationale: 500 mg ÷ 250 mg/mL = 2 mL.
, Question 10: What is a contraindication for administering ibuprofen?
A) Hypertension
B) Active peptic ulcer disease
C) Asthma without NSAID sensitivity
D) Diabetes
Rationale: Ibuprofen can worsen peptic ulcer disease due to GI irritation.
Question 11: A patient on digoxin reports nausea and blurred vision. What should the nurse
suspect?
A) Hypokalemia
B) Digoxin toxicity
C) Dehydration
D) Allergic reaction
Rationale: Nausea and blurred vision are signs of digoxin toxicity.
Question 12: What is the primary indication for furosemide?
A) Pain management
B) Diuresis for edema or hypertension

D) Hypotension
Rationale: Prednisone, a corticosteroid, causes weight gain due to fluid retention.
Question 15: A patient receives atropine in an emergency. What is its primary action?
A) Reduces pain
B) Increases heart rate
C) Lowers blood pressure
D) Reverses opioid overdose
Rationale: Atropine, an anticholinergic, increases heart rate in bradycardia.
Question 16: What should a nurse monitor in a patient taking spironolactone?
A) Blood glucose
B) Potassium levels
C) Platelet count
D) INR
Rationale: Spironolactone, a potassium-sparing diuretic, can cause hyperkalemia.
