Which of the following is NOT considered a symptom of uremia?

Uremia is a condition characterized by the buildup of waste products in the blood due to impaired kidney function, leading to a variety of symptoms. Elevated hematocrit refers to the proportion of blood volume occupied by red blood cells, and in uremic patients, this is often not elevated but rather can be low or normal due to anemia commonly associated with chronic kidney disease.

The other symptoms listed—decreased ability to concentrate, itching, and lack of appetite—are well-documented issues associated with uremia. Decreased ability to concentrate stems from the effects of toxins on the central nervous system, itching is often due to the accumulation of waste products and disturbances in calcium and phosphorus metabolism, and lack of appetite is a common manifestation of the overall distress the body experiences when uremic toxins accumulate.

Therefore, while symptoms of uremia can include various effects on the body, having an elevated hematocrit would not be consistent with the condition, making it the correct choice for what is NOT considered a symptom of uremia.
