- A urinalysis reveals that the patients urine contains glucose, hemoglobin, and white blood cells (pus). Are any of these substances abnormal in urine? Explain.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.which blood pH would cause the kidneys specifically the collecting ducts to excrete bicarbonate (HCO3-) into the blood? note: this works through the carbonic acid bicarbonate buffer system. Basic, acidic, or neutral.
- Description for Thomas Addis:Scottish-American scientistIdentified the different types of castFirst attempt to standardize quantitation of formed elements in urine Which among the statements below is(are) CORRECT?The Rocking microtome was invented in 1881George Adams Jr was able to discover the effects of formaldehyde as a fixative Heat fixation is the best fixation method used in preserving tissuesNone of the aboveThe presence of either protein or glucose in a urinalysis is abnormal, but these two molecules end up in the urine for different reasons. For each of these molecules, briefly describe where in the urine production process (i.e., glomerular filtration, tubular reabsorption or tubular secretion) the problem occurs, and why it might happen.Gout—a condition that results in joint swelling and pain—is caused by the formation of sodium urate (NaC5H3N4O3) crystals within tendons, cartilage, and ligaments. Sodium urate precipitates out of blood plasma when uric acid levels become abnormally high. This sometimes happens as a result of eating too many rich foods and consuming too much alcohol, which is why gout is sometimes referred to as the “disease of kings.” If the sodium concentration in blood plasma is 0.140 M, and Ksp for sodium urate is 5.76 * 10 - 8, what minimum concentration of urate would result in precipitation?
- A physician calls the laboratory and asks what lab tests should be requested to assess the acid-base balance function of a patient's renal system. You reply: 1) Serum rennin and erythropoietin 2) Serum creatinine, serum urea, serum uric acid, and creatinine clearance 3) Serum bilirubin (conjugated and total), urine urobilinogen 4) Serum bicarbonate and blood pH no references, just homeworkNearly all renal diseases result in hypertension. In fact, some clinicians have a 'rule' that states "unexplained hypertension is always a result of a problem with the kidneys until proven otherwise". Briefly explain why hypertension occurs in renal disease.Answer the following questions: a. Is glucose normally present in urine? In what condition can it be detected in urine? b. In the presence of positive result in Fehling's and Benedict's tests, how would you eliminate the reducing effect of uric acid and creatinine?
- The renal handling of a novel drug is being studied. When the drug is present in the blood, it is filtered into the Bowman’s capsule and secreted via transport proteins in the renal tubules, but it is NOT reabsorbed. The lines on the following graph represent filtration, secretion and excretion rates of this drug at various plasma concentrations. For the three lines shown (labeled A-C) identify which line represents filtration, which line represents secretion, and which line represents excretion Explain how you determined this.The presence of either protein or glucose in a urinalysis is abnormal but they end up in the urine for different reasons. For each of these molecules, briefly describe where in the urine production process (i.e., glomerular filtration, tubular reabsorption or tubular secretion) the problem occurs, and why it might happen. please helpPhysiological processes are dictated by the laws of chemistry and physics. Give one example each of how a law of chemistry and a law of physics are important in understanding the regulation of renal function.
