Bumetanide, Hydrochlorothiazide), built for
fast revision and clinical decision-making.
1.
A nurse is assessing a client receiving furosemide. Which
electrolyte imbalance is the priority to monitor?
A. Hypernatremia
B. Hyperkalemia
,C. Hypokalemia
D. Hypercalcemia
Answer: C. Hypokalemia
Rationale:
Loop diuretics like furosemide increase potassium excretion,
leading to hypokalemia, which can cause dysrhythmias.
• A: Sodium may decrease, not increase
• B: Opposite effect
• D: Loop diuretics promote calcium excretion

(Furosemide – Adverse Effects)
2.
Which finding requires immediate nursing action in a client
receiving bumetanide?
A. Urine output of 600 mL/day
B. Potassium level of 2.9 mmol/L
C. Mild thirst
D. Blood pressure 130/80 mmHg
Answer: B. Potassium level of 2.9 mmol/L
Rationale:
A potassium level <3.5 mmol/L indicates hypokalemia,
increasing risk for cardiac dysrhythmias.
, • A: Low but not immediately life-threatening
• C: Expected
• D: Normal
Citation: Mosby’s (Bumetanide – Monitoring & Adverse Effects)
3.
A client taking hydrochlorothiazide reports muscle weakness.
What is the nurse’s best action?
A. Reassure the client
B. Assess potassium level
C. Restrict fluids
D. Administer sodium
Answer: B. Assess potassium level
Rationale:
Thiazides cause potassium loss, leading to weakness.
• A: Unsafe without assessment
• C: May worsen dehydration
• D: Not indicated
Citation: Mosby’s (Hydrochlorothiazide – Adverse Effects)
4.
, Which instruction is most important for a client starting
furosemide?
A. Take medication at bedtime
B. Avoid potassium-rich foods
C. Change positions slowly
D. Increase sodium intake
Answer: C. Change positions slowly
Rationale:
Furosemide can cause orthostatic hypotension.
• A: Should be taken in morning
• B: Opposite—potassium intake may be needed
• D: Not recommended
Citation: Mosby’s (Furosemide – Patient Teaching)
5.
Which lab value indicates therapeutic effectiveness of
bumetanide?
A. Increased blood glucose
B. Decreased edema
C. Elevated potassium
D. Increased creatinine
Answer: B. Decreased edema
