1.
A 55-year-old patient with a history of chronic hypertension is prescribed
lisinopril.
Which adverse effect should the nurse monitor most closely?
a) Hyperglycemia
b) Dry cough
c) Bradycardia
d) Constipation
Correct Answer: b) Dry cough
Rationale: ACE inhibitors cause bradykinin accumulation, leading to a persistent
dry cough.
2.
A client presents with atrial fibrillation and is prescribed warfarin.
Which lab value should guide therapy?
a) aPTT
b) INR
c) Platelets
d) Hemoglobin
Correct Answer: b) INR
Rationale: Warfarin effectiveness is monitored by INR, target 2–3 for most
conditions.
,3.
Which drug is considered the first-line treatment for acute asthma exacerbation?
a) Montelukast
b) Albuterol
c) Theophylline
d) Fluticasone
Correct Answer: b) Albuterol
Rationale: Short-acting beta agonists (SABA) provide rapid bronchodilation in
acute asthma.
4.
A nurse reviews labs for a patient on lithium therapy.
Which finding is most concerning?
a) Sodium 128 mEq/L
b) Potassium 4.0 mEq/L
c) Sodium 137 mEq/L
d) Calcium 9.0 mg/dL
Correct Answer: a) Sodium 128 mEq/L
Rationale: Hyponatremia increases lithium reabsorption, raising risk for toxicity.
5.
Which drug is an antidote for benzodiazepine overdose?
a) Protamine sulfate
b) Naloxone
c) Flumazenil
d) Atropine
Correct Answer: c) Flumazenil
Rationale: Flumazenil is a benzodiazepine receptor antagonist used in overdose.
,6.
A client with heart failure is prescribed furosemide.
Which lab result requires priority follow-up?
a) Sodium 136 mEq/L
b) Potassium 2.9 mEq/L
c) BUN 15 mg/dL
d) Chloride 100 mEq/L
Correct Answer: b) Potassium 2.9 mEq/L
Rationale: Loop diuretics cause potassium loss; hypokalemia increases arrhythmia
risk.
7.
Which drug is classified as a beta-1 selective blocker?
a) Metoprolol
b) Propranolol
c) Nadolol
d) Carvedilol
Correct Answer: a) Metoprolol
Rationale: Metoprolol is cardioselective, blocking beta-1 receptors primarily in
the heart.
8.
A patient on isoniazid (INH) for tuberculosis develops numbness and tingling in
the hands.
Which supplement should the nurse anticipate?
a) Vitamin C
b) Vitamin B6 (pyridoxine)
c) Vitamin D
d) Vitamin K
, Correct Answer: b) Vitamin B6 (pyridoxine)
Rationale: INH depletes pyridoxine, causing peripheral neuropathy;
supplementation prevents this.
9.
The nurse is teaching a patient about nitroglycerin sublingual tablets.
Which instruction is correct?
a) Swallow the tablet with water
b) Keep tablets in the bathroom cabinet
c) Take 1 tablet every 5 minutes, up to 3 doses
d) Chew the tablet for faster effect
Correct Answer: c) Take 1 tablet every 5 minutes, up to 3 doses
Rationale: If chest pain persists after 3 doses in 15 minutes, seek emergency care.
10.
Which lab must be monitored in a client receiving vancomycin IV?
a) TSH
b) Trough level
c) Amylase
d) Bilirubin
Correct Answer: b) Trough level
Rationale: Trough levels prevent nephrotoxicity and ototoxicity from high drug
accumulation.
11.
A nurse prepares to give heparin.
Which lab value ensures safe administration?
a) INR 2.8
b) aPTT 65 seconds
