Quiz: The nurse working in an outpatient nephrology clinic knows that which of the
following are primary functions of the kidneys? (Select all that apply.)
A. Production of clotting factors
B. Homeostasis
C. Excretion of metabolic wastes
D. Regulation of acid-base balance
E. Metabolism of fats
Ans: B, C, D
The kidneys do not metabolize fats.
Production of clotting factors is a primary function of the liver.
The kidneys maintain blood pressure using the RAAS and also produce erythropoietin to
stimulate RBC production.
Quiz: In caring for a patient diagnosed with acute kidney injury, the nephrology nurse
knows that which of the following tests are specific for renal function? (Select all that apply.)
A. Aspartate aminotransferase (AST)
B. Blood urea nitrogen
C. Creatinine
D. Glomerular filtration rate
E. White blood cell count

A. 30-40 mL/min
B. 40-50 mL/min
C. 70-90 mL/min
D. 90-120 mL/min
Ans: D
Normal GFR is 90-120 mL/min
Normal Creatinine 0.6-1.1 for females and 0.6-1.2 for males

, D. No GFR
Ans: B
Aging and renal function:
Decrease in renal blood flow and GFR → altered sodium and water balance
Number of nephrons decrease due to renal vascular and perfusion changes
Response to acid-base changes is delayed
Increased risk for drug toxicity
Alterations in thirst and water intake
Get dehydrated very easily; do not recognize thirst and heat
Decreased muscle mass may lead to decreased creatinine values
Quiz: An older patient is experiencing urinary stasis. The registered nurse knows that
urinary stasis may lead to which of the following?
A. Increased GFR
B. Hypocoagulation
C. Hypertension
D. Infection
