Correct Answer is C

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.

D. Incorrect. Antipyretics such as acetaminophen are generally safe when used appropriately and are not considered a risk factor for chronic renal failure.

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.
