Question 1
A nurse is preparing to administer atenolol to a client with hypertension. Which assessment
should the nurse prioritize before administration?
A. Blood glucose
B. Heart rate
C. Respiratory rate
D. Serum potassium
Correct Answer: B
Rationale: Atenolol, a beta-blocker, can cause bradycardia. The nurse should check the heart
rate before administration and hold the dose if it is below 60 bpm to prevent severe bradycardia.
Question 2
A client is prescribed warfarin for atrial fibrillation. Which laboratory test should the nurse
monitor?
A. aPTT
B. INR
C. Platelet count
D. Serum creatinine
Correct Answer: B
Rationale: Warfarin’s therapeutic effect is monitored using the International Normalized Ratio
(INR), with a target range of 2.0–3.0 for atrial fibrillation to ensure effective anticoagulation.
Question 3
A nurse is administering insulin aspart to a client with diabetes. When should this medication be
given?
A. 30 minutes before meals
, 2
B. At bedtime
C. Immediately before meals
D. 1 hour after meals
Correct Answer: C
Rationale: Insulin aspart, a rapid-acting insulin, is administered immediately before or within 15
minutes of meals to control postprandial glucose spikes.
Question 4
A client is receiving furosemide for heart failure. Which electrolyte imbalance is the nurse most
concerned about?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hypocalcemia
Correct Answer: B
Rationale: Furosemide, a loop diuretic, promotes potassium excretion, increasing the risk of
hypokalemia, which can lead to arrhythmias.
Question 5
A nurse is caring for a client prescribed albuterol for asthma. What is the primary therapeutic
effect?
A. Reduces airway inflammation
B. Promotes bronchodilation
C. Thins mucus secretions
D. Suppresses cough reflex
Correct Answer: B
Rationale: Albuterol, a short-acting beta-2 agonist, relaxes bronchial smooth muscles, causing
bronchodilation to relieve acute asthma symptoms.
Question 6
A client is receiving heparin for a pulmonary embolism. Which laboratory value should the nurse
monitor?
A. INR
B. aPTT
, 3
C. Hemoglobin
D. Serum sodium
Correct Answer: B
Rationale: Heparin’s anticoagulant effect is monitored using activated partial thromboplastin
time (aPTT), with a therapeutic range of 1.5–2.5 times the control value.
Question 7
A nurse is teaching a client about lisinopril for hypertension. Which adverse effect should the
client report?
A. Increased appetite
B. Persistent dry cough
C. Weight loss
D. Improved energy
Correct Answer: B
Rationale: Lisinopril, an ACE inhibitor, commonly causes a dry, persistent cough due to
bradykinin accumulation, which should be reported for possible medication adjustment.
Question 8
A client is prescribed morphine for postoperative pain. What is the priority nursing assessment?
A. Blood pressure
B. Respiratory rate
C. Temperature
D. Heart rate
Correct Answer: B
Rationale: Morphine, an opioid, can cause respiratory depression. The nurse must monitor the
respiratory rate to ensure it remains above 12 breaths per minute.
Question 9
A nurse is preparing to administer metformin to a client with type 2 diabetes. Which condition is
a contraindication?
A. Hypertension
B. Renal impairment
C. Asthma
D. Hyperlipidemia
