A client with chronic renal failure is prescribed phosphate binders. What should the nurse include in the client's education about taking phosphate binders?

"Take the phosphate binders with meals to maximize their effectiveness."

"Phosphate binders can cause constipation, so drink plenty of fluids."

"Avoid taking phosphate binders with calcium supplements to prevent interactions."

"Phosphate binders can lower potassium levels, so monitor your potassium intake."

Answer and Explanation

The Correct Answer is A

A. Correct. Phosphate binders are most effective when taken with meals because they bind to dietary phosphorus, preventing its absorption in the digestive tract.

B. Incorrect. While constipation can be a side effect of some phosphate binders, drinking plenty of fluids is not directly related to this issue.

C. Incorrect. Phosphate binders should be taken with meals, and calcium supplements should be taken separately to prevent interactions between the two medications.

D. Incorrect. Phosphate binders do not typically lower potassium levels, and monitoring potassium intake is not specifically related to their use.

Correct Answer is C

Explanation

A. Incorrect. Severe anemia in chronic renal failure is characterized by low hemoglobin levels, not elevated levels.

B. Incorrect. Chronic renal failure can lead to decreased red blood cell production, resulting in a reduced red blood cell count.

C. Correct. Chronic renal failure often leads to decreased production of erythropoietin, a hormone that stimulates red blood cell production. This deficiency results in low hematocrit levels and severe anemia.

D. Incorrect. Chronic renal failure is not typically associated with elevated platelet counts; in fact, it can lead to platelet dysfunction and an increased risk of bleeding.

QUESTIONS

A. "Pruritus is unrelated to chronic renal failure; it may be due to a skin condition." B. "Itching is a common symptom of chronic renal failure, caused by the buildup of waste products in the blood." C. "Pruritus is a side effect of the medications used to treat chronic renal failure." D. "Persistent itching is a sign of an allergic reaction; let's check if you started any new medications."

Correct Answer is B

Explanation

A. Incorrect. Pruritus (itching) is a common symptom of chronic renal failure and is related to the buildup of waste products and toxins in the blood, leading to skin irritation.

B. Correct. Pruritus is a common and distressing symptom of chronic renal failure, caused by the retention of uremic toxins in the blood. These toxins can irritate the skin and lead to itching.

C. Incorrect. While medications can sometimes cause pruritus as a side effect, it is not the primary cause of itching in clients with chronic renal failure.

D. Incorrect. Persistent pruritus in a client with chronic renal failure is not necessarily indicative of an allergic reaction to medications. It is more likely related to the buildup of waste products in the blood.
