EXAM OVERVIEW
The DaVita RN Final Exam is designed to validate clinical competency for nurses
working in dialysis settings. The exam covers key areas including chronic kidney
disease (CKD) staging and management, hemodialysis and peritoneal dialysis
modalities, vascular access care, dialysis complications, medication management,
patient education, infection control, water treatment, and emergency response.
SECTION 1: CHRONIC KIDNEY DISEASE & RENAL PHYSIOLOGY
Question 1
What is the primary function of the kidneys?
A. To produce red blood cells
B. To filter waste products from the blood and regulate fluid and electrolyte balance
C. To digest food
D. To regulate blood sugar
,Correct Answer: B
Rationale: The kidneys filter waste products (urea, creatinine, uric acid) from the
blood and regulate fluid, electrolyte, and acid-base balance. The kidneys also
produce erythropoietin (EPO), which stimulates red blood cell production, but this
is not their primary function.
Question 2
What is the normal glomerular filtration rate (GFR) range?
A. 15-29 mL/min/1.73m²
B. 30-59 mL/min/1.73m²
C. 60-89 mL/min/1.73m²
D. 90-120 mL/min/1.73m²
Correct Answer: D
Rationale: Normal GFR is approximately 90-120 mL/min/1.73m². A GFR <60
mL/min for three months or more indicates chronic kidney disease. GFR is the best
overall indicator of kidney function.
Question 3
A patient with a GFR of 25 mL/min/1.73m² is in which stage of CKD?
A. Stage 2
B. Stage 3
C. Stage 4
D. Stage 5
,Correct Answer: C
Rationale: CKD Stage 4 is defined by a GFR of 15-29 mL/min/1.73m². Stage 3 is
30-59, Stage 5 is <15, and Stage 2 is 60-89. Stage 4 indicates severe kidney
damage requiring preparation for renal replacement therapy.
Question 4
Which of the following is a classic sign of uremia?
A. Polyuria
B. Pruritus (itching)
C. Hypertension
D. Weight gain
Correct Answer: B
Rationale: Pruritus (itching) is a classic symptom of uremia caused by the
accumulation of waste products in the blood. Other signs of uremia include
nausea, fatigue, anorexia, metallic taste, and mental status changes.
Question 5
What is the most common cause of end-stage renal disease (ESRD) in adults?
A. Hypertension
B. Diabetes mellitus
C. Glomerulonephritis
D. Polycystic kidney disease
, Correct Answer: B
Rationale: Diabetes mellitus is the most common cause of ESRD in adults,
followed by hypertension. Diabetes causes damage to the glomeruli through a
combination of hyperfiltration and metabolic effects.
Question 6
What is the primary role of erythropoietin (EPO)?
A. To regulate blood pressure
B. To stimulate red blood cell production
C. To regulate calcium and phosphorus balance
D. To filter waste products
Correct Answer: B
Rationale: Erythropoietin (EPO) is a hormone produced by the kidneys that
stimulates the bone marrow to produce red blood cells. As kidney function
declines, EPO production decreases, leading to anemia.
Question 7
What is the target hemoglobin range for CKD patients on erythropoiesis-stimulating
agents (ESAs)?
A. 8-10 g/dL
B. 10-12 g/dL
C. 11-12 g/dL
D. 12-14 g/dL
