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.

Answer and Explanation

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 D

Explanation

Choice A reason: Using hard candy to alleviate dry mouth is a common suggestion for clients experiencing dry mouth as a side effect of medications, including herbal supplements like St. John's wort. This information does not require further instruction as it is a helpful and safe practice.

Choice B reason: Insomnia can occur while taking St. John's wort due to its stimulating effects. Clients should be informed about this potential side effect and how to manage it, but this information does not require further instruction as it is accurate and relevant.

Choice C reason: Sensitivity to the sun is a known side effect of St. John's wort. Clients should be advised to use sun protection and avoid excessive sun exposure. This information is correct and does not require further instruction.

Choice D reason: The statement that another form of contraception is not needed requires further instruction because St. John's wort can interact with hormonal contraceptives, potentially reducing their effectiveness. Clients should be advised to use an additional form of contraception to prevent unintended pregnancy.

A. Calcium. B. Pasta, cereal, and bread. C. Bananas, oranges, and peaches. D. Liver, beef, and chicken.

Correct Answer is C

Explanation

Choice A reason: While calcium is an essential mineral, the foods rich in calcium are not the primary concern for a client on furosemide. Furosemide is a diuretic that can cause the loss of potassium, making potassium-rich foods a priority.

Choice B reason: Pasta, cereal, and bread are important for a balanced diet but do not provide the necessary potassium that may be depleted with furosemide use. The nurse should focus on foods that will help replenish potassium levels.

Choice C reason: Bananas, oranges, and peaches are rich in potassium, which is crucial for clients taking furosemide. This diuretic can lead to hypokalemia (low potassium levels), and encouraging the intake of potassium-rich foods can help prevent this condition and manage heart health effectively.

Choice D reason: Liver, beef, and chicken are good sources of protein and iron, but they do not address the potential potassium deficiency caused by furosemide. The emphasis should be on replenishing potassium, not just providing general nutrients.
