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."
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.

Explanation
A. Incorrect. Antibiotics are generally safe and are not known to be a risk factor for chronic renal failure.
B. Incorrect. Antihypertensive medications are essential for managing high blood pressure and reducing the risk of kidney damage in individuals with hypertension. They are not considered a risk factor for chronic renal failure.
C. Correct. Proton pump inhibitors (PPIs) are commonly used to treat conditions such as acid reflux and peptic ulcers. Prolonged and high-dose use of PPIs has been associated with an increased risk of kidney disease, including acute interstitial nephritis and chronic kidney disease.

Correct Answer is C
Explanation
A. Incorrect. The volume of urine produced in 24 hours is measured through a different test called the 24-hour urine collection, not the GFR test.
B. Incorrect. The GFR test does not assess blood glucose levels; it is primarily used to evaluate kidney function.
C. Correct. The GFR test measures how well the kidneys are filtering waste and fluids from the blood. It is an important indicator of kidney function and is commonly used to stage chronic renal failure.
D. Incorrect. The GFR test does not specifically measure the excretion of potassium and sodium in the urine; instead, it focuses on overall kidney function and filtration rate.
