PDF Download FREE AND STUDY GAMES ABOUT URINE EXAM QUESTIONS Actual Qs and Ans Expert-Verified Explanation This Exam contains: -Guarantee passing score -135 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: Which acid is commonly used to precipitate urine protein? Answer: Sulfosalicylic acid (SSA). The protein precipitation test should be performed on the supernatant of a centrifuged urine to avoid false positive reactions. Before automated reagent strip readers, it was common practice to confirm all positive protein res Question 2: What is normal specific gravity of a random urine? Answer: 1.001-1.035. Question 3: At what pH are the formed elements best preserved in the urine? Answer: Acid.Which stain can be used for urine sediment examination? Question 4: What causes a fruity odor in urine? Answer: Ketones. Question 5: What reagent is used to detect ketones on reagent strips? Answer: Sodium nitroprusside.Question 6: A urine specimen for routine urinalysis has been refrigerated overnight. Prior to testing, what two things should be done to the specimen? Answer: It should be brought to room temperature and thoroughly mixed. The enzymatic reactions on the strips may be inhibited if the urine is cold and false negative results may be obtained if RBCs and WBCs have settled to the bottom of the specimen container. Question 7: Which chemical urinalysis tests require confirmation? Answer: The routine use of confirmatory testing for glucose, bilirubin, ketones, and protein has been eliminated in most laboratories. Question 8: What are casts? Answer: Protein molds of the renal tubules. They are characterized by parallel sides and rounded ends. Question 9: What is isothenuria and what is its significance? Answer: Urine specific gravity fixed at 1.010.This is the specific gravity of the plasma filtrate and indicates that the kidneys can neither concentrate nor dilute the urine.Question 10: What are the normal values for the tests on the urine reagent strip? Blood: Answer: negative Question 11: Name the three ketones . Answer: Acetone, acetoacetic acid (diacetic acid), and beta-hydroxybutyric acid (betahydroxybutyrate). Question 12: Which crystal is the only needle found in alkaline urine? Answer: Calcium phosphate. It may appear as rosettes and "pointing fingers". Question 13: What protein is found in all casts? Answer: Uromodulin or Tamm Horsfall protein. Pathological casts (granular, cellular, or waxy) contain albumin as well. Hyaline casts have Uromodulin or Tamm Horsfall only. Question 14: Coffin lids Answer: triple phosphate Question 15: Name the abnormal crystals found in acid urine. Answer: Leucine, tyrosine, cystine, cholesterol, and bilirubin.Question 16: Which is more sensitive for glucose, the reagent strip or copper reduction test? Answer: The reagent strip. Question 17: In what is Urobilinogen soluble? Answer: chloroform and butanol Question 18: What are the normal values for the tests on the urine reagent strip? Bilirubin: Answer: negative Question 19: In what other forms does calcium oxalate appear besides the "envelope"? Answer: Less commonly, it can be dumb-bell shaped or ovoid. When ovoid, it may be mistaken for RBCs. Polarized light can help in the differentiation. Calcium oxalate crystals are strongly birefringent; RBCs are not Question 20: How can the presence of large numbers of yeast affect reagent strip results? Answer: If the urine is not tested promptly or refrigerated, the yeast could metabolize any glucose present and cause a false negative result Question 21: Which sugar(s) does the reagent strip detect? https://www.learnexams.com/study-content/free-and-study-games-about-urine-exam-questions-49170
