D) urinalysis

Question

Quizplus · Accepted Answer

Specific gravity is a laboratory procedure used to determine the concentration or diluting ability of the kidneys. This test measures the density of urine and can help identify conditions such as dehydration or kidney disease. KUB (Kidney, Ureter, Bladder) is a type of imaging test used to visualize the urinary organs but does not provide information on the function of the kidneys. Blood urea nitrogen (BUN) is a blood test that measures the amount of nitrogen in the blood that comes from urea, a waste product of protein metabolism. While elevated BUN levels can indicate kidney dysfunction, it is not a direct measure of kidney function. Urinalysis is a broad term that includes multiple tests performed on a urine sample, but it is not specific to measuring the concentration or diluting ability of the kidneys.
