Question :The nurse working in an outpatient nephrology
clinic knows that which of the following are primary functions of the kidneys? (Select all that apply.)
- Production of clotting factors
- Homeostasis
- Excretion of metabolic wastes
- Regulation of acid-base balance
- Metabolism of fats
Correct answer: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.
Question :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.)
- Aspartate aminotransferase (AST)
- Blood urea nitrogen
- Creatinine
- Glomerular filtration rate
- White blood cell count
Correct answer:B, C, D
AST related to LIVER function
Question :In caring for a patient with acute kidney injury
the nurse knows that the patient's renal function has

returned to normal range when the patient's GFR
measures:
- 30-40 mL/min
- 40-50 mL/min
- 70-90 mL/min
- 90-120 mL/min
Correct answer:D
Normal GFR is 90-120 mL/min Normal Creatinine 0.6-1.1 for females and 0.6-1.2 for males Normal BUN is 10-20 mg/dL
*Be sure to know these normal values, you will use them daily as a nurse
Question :The nursing working in a geriatric living
facility understands that as patients age, which change in glomerular filtration rate is expected?
- | Page
- Increased GFR
- Decreased GFR
- Same GFR
- No GFR
Correct answer: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
