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.

pain. Which of the following should the nurse monitor for potential
adverse effects?
a) Respiratory rate
b) Blood pressure
