Certified Clinical Hemodialysis Technician
(CCHT) Practice Exam Questions with
Correct Answers & Explanations | Graded
A+ Study Guide.


Question 1: The functional unit of the kidney, or the structure in the kidney that does
the work, is the:

 A) Glomerulus
 B) Nephron
 C) Tubule system
 D) Calyx

Correct Answer: B) Nephron

Explanation: The nephron is the functional unit of the kidney responsible for filtering blood
and producing urine. Each kidney contains approximately 1 million nephrons.




Question 2: A nephron is made up of:

 A) A glomerulus and Bowman's capsule
 B) A glomerulus and a tubule system
 C) The cortex and medulla
 D) The loop of Henle only

Correct Answer: B) A glomerulus and a tubule system

Explanation: Each nephron consists of a glomerulus (where blood filtration begins) and a
tubular system (where reabsorption and secretion occur).

, Question 3: The leading cause of chronic kidney disease in adults in the United States
is:

 A) Hypertension
 B) Glomerulonephritis
 C) Diabetes
 D) Polycystic kidney disease

Correct Answer: C) Diabetes

Explanation: Diabetes is the leading cause of chronic kidney disease and end-stage renal
disease in the United States, followed by hypertension.




Question 4: Normal body pH is:

 A) 6.8-7.0
 B) 7.0-7.35
 C) 7.35-7.45
 D) 7.45-7.55

Correct Answer: C) 7.35-7.45

Explanation: Normal arterial blood pH ranges from 7.35 to 7.45. Values outside this range
indicate acidosis or alkalosis.




Question 5: Which of the following is NOT a symptom of uremia?

 A) Fatigue
 B) Elevated hematocrit
 C) Nausea
 D) Itching

Correct Answer: B) Elevated hematocrit

, Explanation: Uremia causes anemia (low hematocrit) due to decreased erythropoietin
production by the kidneys, not elevated hematocrit.




Question 6: Uremia may cause which of the following conditions?

 A) Itching
 B) Edema of the extremities
 C) Anemia
 D) All of the above

Correct Answer: D) All of the above

Explanation: Uremia (accumulation of waste products in the blood) can cause multiple
symptoms including pruritus (itching), edema, anemia, fatigue, nausea, and neurological
changes.




Question 7: All of the following substances are produced by the kidney EXCEPT:

 A) Renin
 B) Aldosterone
 C) Erythropoietin
 D) Calcitriol

Correct Answer: B) Aldosterone

Explanation: Aldosterone is produced by the adrenal glands, not the kidneys. The kidneys
produce renin, erythropoietin (EPO), and calcitriol (active vitamin D).




Question 8: The normal adult glomerular filtration rate (GFR) is approximately:

 A) 50 mL/min/1.73 m²
 B) 75 mL/min/1.73 m²

,  C) 125 mL/min/1.73 m²
 D) 200 mL/min/1.73 m²

Correct Answer: C) 125 mL/min/1.73 m²

*Explanation: Normal GFR is approximately 125 mL/min/1.73 m². A GFR below 15
mL/min/1.73 m² indicates kidney failure (Stage 5 CKD).*




Question 9: Which kidney structure connects with and delivers urine directly to the
ureter?

 A) Pelvis
 B) Calyx
 C) Glomerulus
 D) Cortex

Correct Answer: A) Pelvis

Explanation: The renal pelvis collects urine from the calyces and funnels it into the ureter
for transport to the bladder.




Fluid Management & Dry Weight
Question 10: Mrs. Smith's dry weight is 62 kg. Her pretreatment weight is 67 kg.
Priming saline is 240 mL, fluid from medication is 100 mL, and she is not allowed fluids
during treatment. What is the total amount of fluid weight to be removed during her
treatment?

 A) 5,000 mL
 B) 5,340 mL
 C) 5,540 mL
 D) 6,000 mL

Correct Answer: C) 5,540 mL
