Urinalysis Questions and Answers with Verified Solutions

Urinalysis Questions and Answers with Verified Solutions Q: What percentage of urine comprises water and solutes? A: Urine consists of approximately 95% water and 5% solutes. Explanation: Urine is primarily composed of water, making up about 95% of its volume. The remaining 5% consists of dissolved solutes, which include various waste products, ions, and other substances that are filtered out from the blood by the kidneys. Q: What components are included in a urinalysis, excluding which of the following? A: A urinalysis typically includes all of the following except for body temperature analysis. Explanation: A urinalysis is a comprehensive test that involves the physical, chemical, and microscopic examination of urine. It assesses various aspects such as color, clarity, pH, specific gravity, presence of proteins, glucose, ketones, cells (like red blood cells and white blood cells), and other substances. Body temperature analysis is not part of a standard urinalysis. 2 Q: Which substance is used to stain microscopic solids for identification purposes? A: Microscopic solids are stained with semi-stain to facilitate identification. Explanation: In laboratory settings, microscopic solids in urine samples are often stained to enhance visibility under a microscope. This staining process helps in identifying cellular elements like white blood cells, red blood cells, casts, crystals, and other sediment components present in the urine.
