Urinalysis Questions and Answers Already Graded A Q: What volume of urine is typically excreted in a 24-hour period under normal conditions? A: Typically, 0.8 to 2.0 liters of urine is excreted in a 24-hour period under normal conditions. Q: For each of the following substances, would they be more concentrated in urine compared to glomerular filtrate under normal conditions? A: Phosphate ions, sulfate ions, potassium ions, urea, uric acid, and creatinine are generally more concentrated in urine compared to glomerular filtrate under normal conditions. Q: For each of the following substances, would they be less concentrated in urine compared to glomerular filtrate under normal conditions? A: Water, sodium ions, amino acids, and glucose are typically less concentrated in urine compared to glomerular filtrate under normal conditions. Q: For each of the following substances, would they be absent from both urine and glomerular filtrate under normal conditions? 2 A: Under normal conditions, albumin, red blood cells, pus (white blood cells), and nitrites are absent from both urine and glomerular filtrate. Q: Why is urinalysis a routine part of a thorough physical examination? A: Urinalysis is routinely performed as it helps identify abnormal constituents in urine that may indicate underlying health issues. Q: What pigment gives urine its typical yellow color? A: The normal yellow color of urine is primarily due to urochrome pigment. Q: Which has a higher specific gravity: 1 ml of urine or 1 ml of distilled water? Explain. A: 1 ml of urine has a higher specific gravity than 1 ml of distilled water because urine contains dissolved solutes that increase its density. Q: Describe the relationship between urine color, specific gravity, and volume. A: Generally, as urine volume decreases, specific gravity increases, leading to a darker color due to higher solute concentration. Q: Name three components that may indicate the presence of a urinary tract infection. 3 A: White blood cells (pus), red blood cells, and casts are indicators that may suggest a urinary tract infection. Q: How does a urinary tract infection affect urine pH? A: A urinary tract infection tends
