Bio 106 Lab 9 Submission Sheet

Lab 9 Submission Sheet Test all five urine specimens for SG, Ph, blood, glucose, protein. Remember to note the color and turbidity. Once you have completed the urinalysis for each, match the unknown to the patient in the case scenarios given. Give a name to the condition described by the case. When you are finished testing all 5 samples, you will have one that doesn’t match a case. What can you say about this sample?

Review Questions 1. You read about nephrotic syndrome in this lab. You know the cause is the loss of plasma protein (mostly albumin) through the kidney. As the albumin level of the blood decreases the oncotic pressure of the blood decreases. What compensatory mechanisms would come into play as the kidney would read this situation as low arterial pressure? Hint: What mechanisms come into play when the BP is low? You need chapter 18 info to answer this! Control mechanisms would come into play as the kidney would read this situation as low arterial pressure. 2. You read about glomerulonephritis in this lab. You know that the glomerular capillaries are damaged or destroyed in this disease. How would this type of damage contribute to the development of hypertension (high blood pressure) in the patient? The damage to the glomerular capillaries impairs the ability of kidney to excrete sodium. When sodium can’t not be excreted it retains water in which fluid valium causes increased blood pressure 3. What does the specific gravity of the urinalysis test? Specific gravity tests the measure of the concentration of solutes in the urine. 4. Name two conditions that would result in a person having blood in the urine. Kidney stones, UTI
