VERSIONS 2024/2025
Question 1:
A nurse is caring for a client who is prescribed furosemide for heart
failure. Which of the following should the nurse monitor for potential
adverse effects?
a) Potassium levels
b) Calcium levels
c) Magnesium levels
d) Sodium levels
Answer: a) Potassium levels
Rationale: Furosemide is a loop diuretic that increases urine output,
which can cause the loss of electrolytes, including potassium. The nurse
should monitor potassium levels to prevent hypokalemia, which can
lead to serious cardiac arrhythmias.
Question 2:
A nurse is teaching a client about taking warfarin. Which of the
following instructions should the nurse include?
a) "You will need to avoid foods high in vitamin K."
b) "Take your warfarin dose on an empty stomach for better
absorption."
c) "This medication will increase your blood pressure."
d) "Warfarin will make your urine turn dark red."
,Answer: a) "You will need to avoid foods high in vitamin K."
Rationale: Warfarin is an anticoagulant that works by inhibiting the
effects of vitamin K, which is essential for blood clotting. A diet high in
vitamin K can interfere with the medication's effectiveness, so clients
should avoid foods such as leafy greens.
Question 3:
A nurse is caring for a client who is prescribed morphine for severe
pain. Which of the following should the nurse monitor for potential
adverse effects?
a) Respiratory rate
b) Blood pressure
c) Blood glucose levels
d) Hemoglobin levels
Answer: a) Respiratory rate
Rationale: Morphine is an opioid analgesic that can depress the
respiratory system. The nurse should monitor the client's respiratory
rate to detect respiratory depression, a common and potentially life-
threatening side effect.
Question 4:
A nurse is caring for a client who is taking atenolol for hypertension.
The nurse should monitor the client for which of the following adverse
effects?
a) Bradycardia
b) Tachycardia
c) Hypertension
d) Hyperkalemia
, Answer: a) Bradycardia
Rationale: Atenolol is a beta-blocker that reduces heart rate and blood
pressure. The nurse should monitor for bradycardia (a heart rate below
60 bpm) as a common side effect.
Question 5:
A nurse is preparing to administer insulin to a client with type 1
diabetes. Which of the following is the priority action for the nurse
before administering insulin?
a) Check the client's blood glucose level.
b) Review the client's last meal.
c) Measure the client's body temperature.
d) Ask the client about recent exercise.
Answer: a) Check the client's blood glucose level.
Rationale: Before administering insulin, it is essential to check the
client’s blood glucose level to ensure it is within the prescribed range.
Administering insulin without checking the blood sugar could lead to
hypoglycemia.
Question 6:
A nurse is caring for a client who is taking digoxin. Which of the
following signs and symptoms should the nurse monitor for, indicating
a potential digoxin toxicity?
a) Bradycardia and visual disturbances
b) Tachycardia and muscle weakness
