Urinary Physiology (Unit 30) Please watch this video about Urinalysis, focusing on gross examination of the sample, and answer the questions below 1. What is a urinalysis (UA), and what can it evaluate? 2. What are the 3 categories of information that can be obtained from a UA? 3. Apart from hydration status, what other factors may influence urine color? a. Beets aside, what might red urine suggest? b. What medical condition might orange urine suggest? What might be the cause of this? 4. What is meant by the turbidity of urine? 5. What might turbid urine suggest? Please watch this second video about Urinalysis, focusing on the use of a commercially available "dipstick" for chemical analysis of a urine sample, and answer the questions below 6. Describe the general procedure for using a "dipstick" to assess a urine sample. 7. What is urine specific gravity? 8. Is urine usually more dense or less dense than water? Why? 9. What is generally considered a "normal" urine specific gravity? 10. What might a urine specific gravity approaching 1.001 suggest (ATN is Acute Tubular Necrosis, the discussion of which goes beyond the scope of this course)? 11. What might a urine specific gravity approaching 1.035 suggest? Why would the syndrome of inappropriate ADH secretion (SIADH) cause a high urine specific gravity? 12. What is the normal pH range of urine? What conditions might affect urine pH?
