The nurse is caring for a client in acute renal failure. Which of the following would indicate to the nurse that the client is uremic? A. BUN of 32 mg/dl B. Serum calcium of 10.5 mg/dl C. Serum potassium of 2.8 mg/dl D. Urine specific gravity of 1.030

To determine if the client is uremic, the nurse should assess the given options and look for signs of uremia. Uremia is a condition that occurs when the kidneys are unable to effectively filter waste products from the blood, leading to an accumulation of toxins. Let's analyze each option:

A. BUN (blood urea nitrogen) of 32 mg/dl: An elevated BUN level indicates impaired kidney function, which is commonly seen in acute renal failure. This could be a potential indicator of uremia.

B. Serum calcium of 10.5 mg/dl: While an abnormal calcium level can be associated with renal failure, it is not a specific indicator of uremia. Other factors should be considered.

C. Serum potassium of 2.8 mg/dl: A low potassium level is not typically associated with uremia. In fact, hyperkalemia (high potassium) is more commonly seen in renal failure.

D. Urine specific gravity of 1.030: A high urine specific gravity suggests concentrated urine, which can be a sign of dehydration or reduced kidney function. While it may be related to renal failure, it is not a specific indicator of uremia.

Based on the options provided, the most indicative finding of uremia would be an elevated BUN level (option A). However, it is important to consider the client's overall clinical presentation and additional laboratory values to make a definitive diagnosis. The nurse should consult with the healthcare team and further assess the client's symptoms and medical history to confirm the presence of uremia.
