A client with acute renal failure develops severe hyperkalemia. What would the nurse anticipate to be used to treat this imbalance?
Select one:

Sodium polystyrene sulfonate (Kayexalate)

Furosemide

10% calcium gluconate IV

Dextrose with regular insulin IV

Answer and Explanation

The Correct Answer is D

A. Sodium polystyrene sulfonate removes potassium via the GI tract, but acts slowly and is not used for severe or emergency hyperkalemia.
B. Furosemide is a loop diuretic that can help excrete potassium if kidney function allows, but it is not reliable in acute renal failure.
C. Calcium gluconate is used to stabilize the cardiac membrane, not to lower potassium levels. It prevents arrhythmias but doesn't remove potassium.
D. A combination of dextrose and regular insulin IV is commonly used in emergencies. Insulin drives potassium into the cells, rapidly lowering serum potassium levels, and dextrose prevents hypoglycemia from insulin administration.

Correct Answer is F

Explanation

A. This option applies only when glucose exceeds 400 mg/dL. This client’s level is 351 mg/dL.
B. The glucose level of 351 mg/dL is much higher than this range.
C. This dose applies to a lower glucose range of 251–300 mg/dL.
D. No insulin is given when glucose is below 200 mg/dL, which is not the case here.
E. The client's level is above 350 mg/dL, so this dose of 6 units is inadequate.
F. A blood glucose level of 351 mg/dL falls within the 351–400 mg/dL range, which corresponds to administering 8 units of regular insulin according to the sliding scale.

A. Administer an antibiotic per orders. B. Offer a warm sitz bath. C. Recommend drinking cranberry juice. D. Encourage decreasing oral fluids.

Correct Answer is A

Explanation

A. Treating the infection promptly with antibiotics is the highest priority in managing a UTI. This helps eliminate the causative bacteria, reduce symptoms, and prevent complications like pyelonephritis or sepsis.

B. Offering a warm sitz bath is helpful but not priority. While this may relieve discomfort or dysuria, it does not treat the underlying infection.

C. Cranberry juice may help prevent future UTIs but does not treat active infections.

D. Clients with a UTI should be encouraged to increase fluid intake, not decrease, to help flush out bacteria from the urinary tract.
