1. A nurse is preparing to administer digoxin to a patient. Which assessment is
the priority before giving the medication?
A. Apical pulse rate
B. Blood pressure
C. Respiratory rate
D. Oxygen saturation
Answer: A
Rationale: The nurse must check the apical pulse for one full minute. Digoxin is usually
withheld if the pulse is less than 60 beats per minute in adults.
2. Which laboratory value must be monitored closely for a patient receiving
warfarin?
A. aPTT
B. Platelet count
C. INR
D. Serum creatinine
Answer: C
Rationale: The International Normalized Ratio (INR) is the standard test for monitoring
the therapeutic levels of warfarin.
,3. The nurse is educating a patient about a new prescription for furosemide.
Which dietary instruction is most important?
A. Follow a high-protein diet
B. Avoid foods high in Vitamin K
C. Limit intake of dairy products
D. Increase intake of potassium-rich foods
Answer: D
Rationale: Furosemide is a loop diuretic that causes potassium loss. Patients should
increase potassium intake to prevent hypokalemia.
4. A patient is prescribed sublingual nitroglycerin. How should the nurse instruct
the patient to take this medication?
A. Swallow the pill with a full glass of water
B. Crush the pill and mix it with applesauce
C. Chew the tablet thoroughly before swallowing

C. Naloxone
D. Flumazenil
Answer: A
Rationale: Protamine sulfate is the specific antagonist used to reverse the effects of
heparin.
, 6. The nurse is caring for a patient receiving morphine sulfate via PCA. Which
assessment is most critical?
A. Respiratory rate
B. Bowel sounds
C. Temperature
D. Urine output
Answer: A
Rationale: Morphine is an opioid that can cause respiratory depression; monitoring the
respiratory rate is a priority safety assessment.
7. What is the primary purpose of the ‘Six Rights’ of medication administration?
A. To speed up the medication process
B. To ensure nursing staff convenience
C. To reduce the cost of healthcare
D. To prevent medication errors
Answer: D
Rationale: The Six Rights (Patient, Drug, Dose, Route, Time, Documentation) are designed
to promote safety and prevent errors.
8. A patient is prescribed a new ACE inhibitor for hypertension. Which side
effect should the nurse tell the patient to report immediately?
A. Orange-colored urine
B. Increased appetite
C. Dry, persistent cough
