Urine-specific gravity is a measure of the concentration of solutes in the urine. It measures the ratio of urine density compared with the water density and provides information on the kidney’s ability to concentrate urine. A urinary-specific gravity measurement is a routine of urinalysis. The normal reference range is 1.005 to 1.030. Andrea, Oliver, and Jerome filled a 28.50-gram pycnometer. When filled full of water, it weighs 53.50 grams, and when filled with their urine sample, it weighs 54.64 grams (Andrea), 53.57 grams (Oliver), and 53.91 grams (Jerome), respectively. EVALUATE THE STATEMENT. (I) Andrea’s urine sample has a specific gravity of 1.0046, while (II) Oliver’s is 1.0028. I is true, II is false. I is false, II is true. Both I and II are true. Both I and II are false.
The laboratory received a 24-hour urine collection from a 26-year old male (body surface area = 2.34m2), and the total urine collection volume measured 800 mL in 24 hours. After creatinine determinations were performed by the alkaline picrate method, interpret the result. Plasma creatinine: 1.2 mg/dL Urine creatinine: 150 mg/dL a. The creatinine clearance of the patient is above reference range. b. The creatinine clearance of the patient is below reference range. c. The creatinine clearance of the patient is within reference range. d. The creatinine clearance of the patient is borderline high.
The nurse is collecting a 24-hour urine specimen. List three (3) elements that can be measured when collected in this manner
The first step of a urinalysis procedure, before testing with a reagent stick, is to visually examine the urine for color, clarity and odor. These properties should be considered in addition to a patient’s clinical presentation, fluid intake and urine output. In the case of Sample B, the patient has presented with an overall healthy appearance. The quantity of urine is normal, the clarity of the urine is clear, but the color of the urine is tinged red, the odor is strong, and the patient is alarmed. From the following, select ALL questions which the patient should be asked, to help determine the cause of the color and odor changes. a. menstruation should be ruled out in females b. consumption of beets c. consumption of asparagus d. consumption of strawberries

A urinalysis is a test that examines physical, chemical and microscopic aspects of urine. Examining urinary fluid can reveal much about the functioning of the body, as changes from the normal characteristics or appearance may reflect specific diseases. Currently, commercially-available chemical reagent sticks can be used to detect substances in urine. Of the following, which are substances that reagent sticks can test for? a. Substances produced by the body, and naturally found in urine. b. Substances produced by the body, but not usually present in urine. c. Substances not normally found in the body. d. a. and c. only e. a., b., and c.
A 35-year-old man (height 67 inches, weight 73.3 kg) with known chronic renal disease for 6 months has blood drawn for serum creatinine and urea tests. Urine is collected for a 24-hour quantitative creatinine test; the total volume of urine collected is 1139 mL. The following laboratory results are obtained for the testing done: Urine creatinine: 56 mg/dL Serum creatinine: 9.6 mg/dL Serum urea: 75 mg/dL Questions 1. What does an elevated serum blood urea nitrogen (BUN) suggest? 2. What does an elevated creatinine suggest? 3. What is the clinical significance of the GFR and the urea nitrogen/creatinine ratio?

How to interpret this urinalysis test?
A patient brings a first morning specimen to the laboratory at 1:00 p.m. Questions:a. How could this affect the urinalysis results?b. What could the patient say that would make the specimen satisfactory for testing?
Your laboratory supervisor asks you to determine a patient’s 24-hour creatinine clearance. The urinesample reported on the laboratory report is 580 mL. The plasma creatinine level is reported as 10 mg/L.In addition, the urine creatinine concentration was 820 mg/L.Use the information in the case and determine the 24-hour creatinine clearance of this patient. Takeinto consideration the 24-hour duration.
