Answer and Explanation

The Correct Answer is D

A. Decreases the chance of peptic ulcer formation: Calcium carbonate is not an antiulcer medication.

B. Prevents constipation: Calcium carbonate can cause constipation, not prevent it.

C. Increases the tubular excretion of potassium: Calcium carbonate does not directly affect potassium excretion.

D. To lower phosphorus levels: Calcium carbonate is a phosphate binder that reduces phosphorus absorption from food. In chronic renal failure, phosphorus builds up due to decreased kidney excretion, leading to secondary hyperparathyroidism and bone disease (renal osteodystrophy).

A. " I can’t wait to start back to work next week, I really need the money.” B. "I will follow my 1.500 mL fluid restriction." C. "I will take my temperature and if it is above 101 I will call my doctor." D. "I am glad I won't have to keep track of how much I urinate in the day.”

Correct Answer is C

Explanation

A. "I can’t wait to start back to work next week, I really need the money." Returning to work too soon increases the risk of infection and complications. Clients should follow their provider's recommendations.

B. "I will follow my 1,500 mL fluid restriction." After a kidney transplant, patients typically need increased fluid intake to maintain kidney perfusion, not restriction.

C. "I will take my temperature and if it is above 101°F, I will call my doctor." Fever >101°F (38.3°C) is an early sign of infection or organ rejection. Prompt medical attention is required.

D. "I am glad I won't have to keep track of how much I urinate in the day." Clients must monitor urine output to detect signs of kidney rejection or dysfunction.
