A client with chronic kidney disease (CKD) is receiving calcium acetate 667 mg PO. A decrease in which blood value indicates to the nurse that the medication is having the desired effect?
Calcium.
Potassium.
Phosphate.
pH.
The Correct Answer is C
Choice A reason: Calcium acetate is used to bind phosphate in the gastrointestinal tract to reduce phosphate absorption, which is often elevated in clients with CKD. A decrease in serum calcium is not the intended effect of this medication.
Choice B reason: Potassium levels are not directly affected by calcium acetate. This medication specifically targets phosphate binding.
Choice C reason: A decrease in phosphate levels indicates that calcium acetate is effectively binding phosphate and reducing its absorption from the diet. This is the desired effect, as elevated phosphate levels can lead to complications in CKD.
Choice D reason: The pH of the blood is not directly influenced by calcium acetate. The primary purpose of this medication is to manage phosphate levels, not to alter blood pH.

Correct Answer is C
Explanation
Choice A reason: While monitoring for electrolyte imbalance is essential in many scenarios, it is not a primary action specific to administering sucralfate.
Choice B reason: Assessing for secondary Candida infection is not directly related to the administration of sucralfate. This medication is used for its protective effects on the stomach lining.
Choice C reason: Sucralfate should be given on an empty stomach for optimal effectiveness. It forms a protective barrier on the ulcer site and works best when it can directly adhere to the stomach lining without interference from food or other medications.
Choice D reason: Sucralfate is typically administered multiple times a day, not just once a day. Therefore, giving it once a day at bedtime does not follow the standard dosing regimen for this medication.
