A nurse is caring for a client who has chronic kidney disease (CKD) and states she has heartburn.
The provider prescribes aluminum hydroxide. The client asks, "Why can't I just take the antacid magaldrate my husband has at home?" The nurse explains to the client that aluminum hydroxide is the preferred antacid because it lowers which of the following?
Serum magnesium levels
Serum phosphorus levels
Serum potassium levels
Serum calcium levels
The Correct Answer is B
A. Aluminum hydroxide can lead to increased serum magnesium levels, but this is not the reason for its preference in chronic kidney disease.
B. Aluminum hydroxide is preferred because it binds to dietary phosphate, reducing serum phosphorus levels in patients with chronic kidney disease who are prone to hyperphosphatemia.
C. Aluminum hydroxide does not significantly affect serum potassium levels.
D. Aluminum hydroxide can lead to decreased serum calcium levels due to binding, but this is not the primary reason for its preference in chronic kidney disease.
