A nurse is providing discharge teaching for a client who has hypertension and is about to start taking furosemide. Which of the following instructions should the nurse include?
Take the medication at bedtime
Expect some swelling in the hands and feet
Take aspirin if headaches develop
Eat foods that contain plenty of potassium
The Correct Answer is D
A. Take the medication at bedtime: Furosemide is a loop diuretic that increases urine output. Taking it at night can cause nocturia and disrupt sleep. The preferred administration time is in the morning or early afternoon.
B. Expect some swelling in the hands and feet: Furosemide is prescribed to reduce fluid retention, so swelling should improve rather than worsen. Persistent edema should be reported to the healthcare provider.
C. Take aspirin if headaches develop: Aspirin does not treat the cause of hypertension and should not be used routinely to manage symptoms while on furosemide. Medication instructions should focus on safety and monitoring of the prescribed drug.
D. Eat foods that contain plenty of potassium: Furosemide can cause potassium loss, leading to hypokalemia. Consuming potassium-rich foods such as bananas, oranges, and leafy greens helps maintain electrolyte balance and prevent complications like muscle cramps or arrhythmias.

Correct Answer is A
Explanation
A. Joint aspiration of synovial fluid: Analysis of synovial fluid obtained via joint aspiration is the definitive diagnostic test for gout. The presence of monosodium urate crystals under polarized light microscopy confirms the diagnosis.
B. MRI of the joint: MRI can detect joint inflammation and soft tissue changes but cannot specifically identify urate crystals. It is not a definitive test for gout.
C. Serum uric acid level: Elevated uric acid may support a diagnosis, but it is not definitive because levels can be normal during an acute flare or elevated without gout. It is a supportive, not confirmatory, test.
D. X-ray of the affected joint: X-rays can reveal chronic joint changes such as erosions in long-standing gout but do not confirm an acute diagnosis. Imaging is useful for assessing complications but not for definitive diagnosis.
Correct Answer is ["26"]
Explanation
Calculation:
- Identify the prescribed dose and IV concentration
Prescribed Dose: 1,300 units/hr
IV Concentration: 25,000 units in 500 mL
- Calculate the concentration in units per mL
Concentration = 25,000 ÷ 500 = 50 units/mL
- Calculate the infusion rate in mL/hr
Infusion Rate (mL/hr) = Prescribed Dose ÷ Concentration
Infusion Rate = 1,300 ÷ 50
Infusion Rate = 26 mL/hr
