Question 1
A nurse is preparing to administer digoxin to a client with heart failure. Which laboratory result
should the nurse review before administration?
A. Blood glucose
B. Serum potassium
C. Serum sodium
D. Hemoglobin
Correct Answer: B
Rationale: Digoxin toxicity is increased in the presence of hypokalemia. The nurse must review
the serum potassium level to ensure it is within the normal range (3.5–5.0 mEq/L) to prevent
adverse effects like arrhythmias.
Question 2
A client is prescribed warfarin. Which food should the nurse instruct the client to limit?
A. Oranges
B. Spinach
C. Potatoes
D. Apples
Correct Answer: B
Rationale: Spinach is high in vitamin K, which can antagonize the anticoagulant effects of
warfarin. The nurse should advise the client to limit intake of vitamin K-rich foods to maintain
therapeutic INR levels.
Question 3
A nurse is administering insulin glargine to a client with type 1 diabetes. At what time should
this medication be given?
, 2
A. Before breakfast
B. At bedtime
C. After lunch
D. With dinner
Correct Answer: B
Rationale: Insulin glargine is a long-acting insulin with a 24-hour duration. It is typically
administered at bedtime to provide consistent basal insulin coverage throughout the day and
night.
Question 4
Which adverse effect should the nurse monitor for in a client receiving furosemide?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hyponatremia
Correct Answer: B
Rationale: Furosemide, a loop diuretic, increases potassium excretion, leading to a risk of
hypokalemia. The nurse should monitor potassium levels and assess for symptoms like muscle
weakness.
Question 5
A client is prescribed albuterol via inhaler for asthma. What is the primary action of this
medication?
A. Reduces airway inflammation
B. Dilates bronchioles
C. Suppresses cough
D. Thins mucus secretions
Correct Answer: B
Rationale: Albuterol is a short-acting beta-2 agonist that relaxes smooth muscles in the airways,
causing bronchodilation to relieve acute asthma symptoms.
Question 6
A nurse is caring for a client receiving heparin. Which laboratory test should be monitored to
assess therapeutic effect?
, 3
A. INR
B. aPTT
C. Platelet count
D. Prothrombin time
Correct Answer: B
Rationale: Activated partial thromboplastin time (aPTT) is used to monitor heparin therapy,
with a therapeutic range typically 1.5–2.5 times the control value to ensure adequate
anticoagulation.
Question 7
A client with hypertension is prescribed lisinopril. Which instruction should the nurse include?
A. Take with grapefruit juice
B. Monitor for persistent dry cough
C. Expect immediate blood pressure reduction
D. Discontinue if swelling occurs
Correct Answer: B
Rationale: Lisinopril, an ACE inhibitor, commonly causes a persistent dry cough as an adverse
effect. The nurse should instruct the client to report this to the provider for possible medication
adjustment.
Question 8
A nurse is administering morphine to a client for pain. Which assessment is the priority?
A. Blood pressure
B. Respiratory rate
C. Heart rate
D. Temperature
Correct Answer: B
Rationale: Morphine, an opioid, can cause respiratory depression. The nurse’s priority is to
monitor the respiratory rate to ensure it remains above 12 breaths per minute.
Question 9
A client is prescribed metformin for type 2 diabetes. Which laboratory value should the nurse
monitor?
A. Serum creatinine
