NURS 231 Portage Pathophysiology Module 8
Exam Renal System
1. Each of the following statements are true regarding control over the GFR
except
ANS The RAA responds when blood pressure rises above normal limits. (false b/c
the RAA responds when blood pressure drops below normal limits.)
2. Which of the following statements is false regarding ADH?
ANS Elevated levels of ADH will lead to dilute urine.
(false b/c DECREASED levels of ADH will lead to dilute urine)
3. Cortical nephrons are characterized by the following except
ANS they originate deep in the cortex (false b/c they originate superficially in the
cortex)
4. Excess accumulation of fluid within the interstitial compartment is charac-
teristic of which of the following fluid imbalances?
ANS edema
5. Reabsorption in the loop of Henle is characterized by the following except
1/3
, ANS-
Na+ and water are reabsorbed in equal proportions
(The loop of Henle reabsorbed more Na+ and Cl- than water)
6. Which of the following is/are true regarding acid-base disorders? (mark all
that apply)
ANS Metabolic disorders are a result of a change in plasma HCO3- levels Respiratory
disorders are a result of a change in plasma CO2 levels
Normal blood pH = 7.35-7.45
7. Acute postinfectious glomerulonephritis is characterized by the following
except
ANS Associated with a poor prognosis as it often leads to CKD
(the prognosis is good when underlying cause is treated)
8. Which of the following is characteristic of chronic transplant rejection?
ANS it involves humoral immunity
9. Which of the following is true of 25-hydroxycholecalciferol?
ANS It is the active form of vitamin D, converted in the liver
10.A patient is said to be in stage 3a kidney disease. What would you expect
their GFR to be?
ANS 70 mL/min/1.73m2
2/3
