A nurse is caring for a client with chronic renal failure who is prescribed phosphate binders. What is the rationale for administering phosphate binders to this client?

To reduce calcium absorption and prevent kidney stone formation.

To decrease phosphate levels and prevent hyperphosphatemia.

To improve iron absorption and manage anemia.

To increase potassium excretion and prevent hyperkalemia.

Answer and Explanation

The Correct Answer is B

A. Incorrect. Phosphate binders are not used to reduce calcium absorption. They are specifically prescribed to control phosphate levels in the blood.

B. Correct. Phosphate binders are medications that bind to dietary phosphorus in the digestive tract, preventing its absorption and reducing phosphate levels in the blood. This helps manage hyperphosphatemia, a common complication in chronic renal failure.

C. Incorrect. Phosphate binders do not improve iron absorption or manage anemia. They are not related to iron metabolism.

D. Incorrect. Phosphate binders do not affect potassium excretion. They are specific to phosphate control in the body and do not impact potassium levels.

Correct Answer is C

Explanation

A. Incorrect. While proper medication adherence can help prevent drug interactions, it is not the primary reason for advising clients to take medications as prescribed in chronic renal failure.

B. Incorrect. Medication adherence may or may not directly impact the cost of treatment, but the main reason for consistent use is to manage the condition effectively.

C. Correct. Adhering to medication regimens in chronic renal failure is crucial for slowing the progression of kidney damage. Medications are prescribed to control blood pressure, manage complications, and reduce the strain on the kidneys.

D. Incorrect. Medication adherence is essential, but it does not eliminate the need for dietary restrictions in chronic renal failure. Dietary modifications are also a vital part of managing the condition effectively.

A. Increase the intake of potassium-rich foods. B. Perform regular weight-bearing exercises. C. Engage in stretching exercises before bedtime. D. Take an over-the-counter calcium supplement.

Correct Answer is C

Explanation

A. Incorrect. Increasing the intake of potassium-rich foods may not be appropriate, especially if the client's potassium levels are already elevated due to chronic renal failure. High potassium levels can lead to muscle cramps.

B. Incorrect. While regular weight-bearing exercises are beneficial for overall health, they may not specifically address or alleviate muscle cramps in chronic renal failure.

C. Correct. Engaging in stretching exercises before bedtime can help reduce the frequency of muscle cramps in clients with chronic renal failure. Stretching can help relax and lengthen muscles, reducing the risk of cramping.

D. Incorrect. Taking over-the-counter calcium supplements without proper evaluation of calcium levels can be dangerous and may contribute to other imbalances in chronic renal failure.
