A client with chronic renal failure reports experiencing frequent muscle cramps. What should the nurse recommend as an appropriate intervention to alleviate this symptom?

A. Incorrect. Administering an antiemetic medication may help relieve nausea, but it is not the priority action in a client with chronic renal failure experiencing anorexia and nausea.

B. Incorrect. Encouraging the client to increase protein intake is not appropriate if they are experiencing anorexia and nausea. Protein intake may need to be adjusted based on the client's symptoms and kidney function.

C. Incorrect. While assessing serum electrolyte levels is important in chronic renal failure, it is not the priority action in this situation. The client's anorexia and nausea require immediate attention.

D. Correct. Monitoring the client's weight and fluid intake is the priority action when the client is experiencing anorexia and nausea. These symptoms may indicate fluid and electrolyte imbalances that need to be addressed promptly.

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.
