The nurse should include which of the following instructions to assist in controlling phosphorus levels for a client in renal failure? A. Increase intake of dairy products and nuts B. Take aluminum-based antacids such as aluminum hydroxide (Amphojel) with or after meals C. Reduce intake of chocolate, meats, and whole grains D. Avoid calcium supplements

To assist in controlling phosphorus levels for a client in renal failure, the nurse should include the following instructions:

1. Reduce intake of chocolate, meats, and whole grains: These foods are high in phosphorus and can contribute to elevated levels in the body. Encourage the client to limit their consumption of these items.

2. Avoid calcium supplements: Calcium supplements can increase the absorption of phosphorus in the body, leading to higher levels. It is important for the client to avoid taking calcium supplements unless specifically prescribed by their healthcare provider.

3. Increase intake of dairy products and nuts: While this may seem contradictory, dairy products and nuts contain lower levels of phosphorus compared to other protein sources. They can be included in the client's diet in moderation, but it is important to monitor portion sizes.

4. Take aluminum-based antacids such as aluminum hydroxide (Amphojel) with or after meals: Aluminum-based antacids can bind to phosphorus in the gastrointestinal tract, reducing its absorption. This can help in controlling phosphorus levels. However, it is important to follow the specific instructions provided by the healthcare provider regarding the timing and dosage of these antacids.

By following these instructions, the client can help control their phosphorus levels and manage their renal failure more effectively. It is important for the nurse to provide further education and support to ensure the client understands and follows these recommendations.
