The nurse reviews data from a new client's kidney function test. Which of the following standards of transplant nursing practice is the nurse primarily performing?

Choice A reason: Aluminum hydroxide does not primarily lower serum calcium levels. Calcium levels are typically managed in CKD patients through other medications and dietary restrictions, as hypercalcemia can occur in these patients.

Choice B reason: Aluminum hydroxide acts as a phosphate binder, which helps to lower serum phosphorus levels in patients with CKD. This is important because high phosphorus levels can lead to bone and heart problems in these patients. The normal range for serum phosphorus is approximately 2.5 to 4.5 mg/dL.

Choice C reason: Aluminum hydroxide does not have a significant effect on serum potassium levels. In CKD, potassium levels are managed through diet and other medications due to the risk of hyperkalemia, which can be life- threatening.

Choice D reason: While magaldrate contains magnesium, which could potentially worsen hypermagnesemia in CKD patients, aluminum hydroxide does not lower serum magnesium levels. Instead, it is less likely to cause elevated magnesium levels compared to magaldrate.

Step 1: The total amount of digoxin required per dose is 125 mcg. We need to convert this to mg because the available tablets are in mg. We know that 1 mg = 1000 mcg, so 125 mcg = 125 ÷ 1000 mg = 0.125 mg.

Step 2: Each tablet contains 0.25 mg of digoxin.

Step 3: To find out how many tablets are needed, we divide the total amount required by the amount in each tablet. So, (0.125 mg ÷ 0.25 mg/tablet).

Step 4: The result is 0.5 tablets.

So, the nurse should administer 0.5 tablets per dose. This is already rounded to the nearest tenth.
