Exam Overview
This comprehensive study guide contains 200 verified questions and answers designed to prepare Patient Care
Technicians (PCTs) for the DaVita Final Exam in alignment with 2026-2027 training program standards, CMS
Conditions for Coverage, and nephrology best practices. Each question is accompanied by a detailed rationale
explaining the underlying dialysis care reasoning, enabling both exam preparation and clinical competency
development. The cognitive distribution reflects actual exam design: approximately 30% recall of facts, 50%
application of knowledge to clinical scenarios, and 20% analysis of complex situations.
The question style is similarly distributed: 75% are scenario-based to test clinical judgment, 20% are direct recall
of essential facts, and 5% require integrated clinical analysis across multiple knowledge domains. Topics span the
full PCT scope of practice, including kidney anatomy and ESRD pathophysiology, hemodialysis transport
mechanisms, water treatment and quality standards, vascular access care and cannulation, infection prevention
aligned with V-tags 110-130, intradialytic complications and emergency response, documentation and legal
standards, medication management and nutrition, patient education and psychosocial support, and integrated
clinical scenarios.

Section 1: Kidney Anatomy, Physiology, and ESRD Fundamentals (Q1 -
Q25)
Q1: A 58-year-old patient with chronic kidney disease asks the PCT why they need to limit fluid
intake. The PCT understands that fluid balance regulation is primarily achieved through which kidney
function?
A. Diffusion of electrolytes across the glomerulus
B. Ultrafiltration that controls water excretion based on body needs [CORRECT]
C. Active transport of proteins into the tubular lumen

D. Osmosis of glucose across the Loop of Henle
Correct Answer: B
Rationale: Ultrafiltration is the kidney's mechanism for controlling fluid balance by regulating water excretion in
response to hydration status. In ESRD, this function is lost and the hemodialysis machine replicates it through
controlled hydrostatic pressure manipulation across the dialyzer membrane.
Q2: A patient on hemodialysis presents with elevated potassium levels. The PCT recognizes that the
kidney's role in electrolyte balance is mediated primarily by which transport mechanism?
A. Diffusion of dissolved particles from high to low concentration [CORRECT]
B. Active secretion of sodium into the peritoneum
C. Osmotic movement of water into Bowman's capsule
D. Convection of large molecular weight proteins
Correct Answer: A
Rationale: Electrolyte balance is achieved through diffusion, where dissolved particles move across a
semipermeable membrane from high to low concentration. During hemodialysis, this same principle removes excess
potassium from the blood into the dialysate, which has a lower potassium concentration.
Q3: A patient with ESRD develops metabolic acidosis. The PCT explains that healthy kidneys
maintain acid-base balance through which mechanism?
A. Secretion of hydrochloric acid into the proximal tubule
B. Bicarbonate buffering and reabsorption [CORRECT]
C. Conversion of ammonia to urea in the collecting duct
D. Excretion of bicarbonate into the urine
Correct Answer: B
Rationale: The kidneys maintain acid-base balance primarily through bicarbonate buffering, reabsorbing filtered
bicarbonate and generating new bicarbonate to neutralize acids. Dialysate contains bicarbonate to replace this lost
function and correct metabolic acidosis during treatment.
Q4: A PCT is teaching a new patient about waste removal during dialysis. Which two waste products
are most effectively removed through diffusion during hemodialysis?
A. Albumin and globulin
B. Urea and creatinine [CORRECT]
C. Sodium and chloride
D. Red blood cells and platelets
Correct Answer: B
Rationale: Urea and creatinine are small molecular weight waste products efficiently removed by diffusion across
the dialyzer membrane. Their concentration is significantly higher in the patient's blood than in the dialysate, driving
movement from blood to dialysate until equilibrium is approached.
Q5: A patient with ESRD has a hemoglobin of 8.2 g/dL. The PCT understands that anemia in kidney
disease is primarily due to deficient production of which hormone?
A. Renin by the juxtaglomerular cells
B. Erythropoietin (EPO) by the peritubular cells [CORRECT]
C. Antidiuretic hormone by the hypothalamus
D. Aldosterone by the adrenal cortex
DaVita PCT Final Exam - 200 Questions Page 3
, DaVita PCT Final Exam Study Guide | 2026/2027 Verified Answers
Correct Answer: B
Rationale: Erythropoietin (EPO) is produced by the peritubular cells of the kidney and stimulates red blood cell
production in the bone marrow. In ESRD, EPO production is severely reduced, leading to normocytic anemia that
requires recombinant EPO therapy during dialysis.
Q6: A patient with ESRD asks why they take a phosphate binder with meals. The PCT knows that the
kidneys activate Vitamin D through conversion to which substance?
A. Cholecalciferol in the liver
B. Calcitriol (1,25-dihydroxyvitamin D) in the kidney [CORRECT]
C. Ergocalciferol in the skin
D. Calcitonin in the thyroid
Correct Answer: B
Rationale: The kidneys convert 25-hydroxyvitamin D to its active form, calcitriol (1,25-dihydroxyvitamin D), which
is essential for calcium absorption from the gut. Without this activation, hypocalcemia develops, contributing to
CKD-MBD and secondary hyperparathyroidism.
Q7: A patient with hypertension and CKD is being evaluated. The PCT recognizes that renin secretion
by the kidney is part of which hormonal system?
A. Hypothalamic-pituitary-adrenal axis
B. Renin-Angiotensin-Aldosterone System (RAAS) [CORRECT]
C. Somatotropic growth axis
D. Hepatic portal system
Correct Answer: B
Rationale: Renin is secreted by the juxtaglomerular cells in response to decreased renal perfusion, low sodium, or
sympathetic stimulation. It activates the RAAS pathway, leading to angiotensin II production and aldosterone
release, which elevates blood pressure and promotes sodium and water retention.
Q8: During an educational session, a patient asks about the basic structural unit of the kidney. The
PCT correctly identifies it as which structure?
A. The renal pyramid
B. The nephron [CORRECT]
C. The renal calyx
D. The collecting duct
Correct Answer: B
Rationale: The nephron is the basic structural and functional unit of the kidney, with approximately one million
nephrons per kidney. Each nephron consists of the renal corpuscle (glomerulus and Bowman's capsule) and the
renal tubule, working together to filter blood and produce urine.
Q9: A nephrologist explains that a healthy adult kidney contains approximately how many nephrons
per kidney?
A. 100,000
B. 500,000
C. 1 million [CORRECT]
D. 5 million
Correct Answer: C
