CCHT PRACTICE EXAMINATION — DIALYSIS PRINCIPLES & PATIENT Comprehensive
CARE Review
1. AAMI Chemical Analysis of water used for hemodialysis is tested:
A. Monthly
B. Quarterly
C. Annually
D. Every 6 months
CORRECT ANSWER C — Annually.
RATIONALE AAMI standards require annual chemical analysis of water used for hemodialysis to ensure compliance with
safety standards. Bacteriologic testing is done monthly. Endotoxin testing follows specific schedules per
facility protocol.
, 2. A dialysis technician observes a drop of blood on the surface of a patient's hemodialysis machine. Which action
should the technician take?
A. Notify the charge nurse and wait for instructions.
B. Clean the machine surface immediately.
C. Document the finding in the patient's chart.
D. Finish the treatment and clean during teardown.
CORRECT ANSWER B — Clean the machine surface immediately.
RATIONALE Blood spills must be cleaned immediately using appropriate disinfectant (1:10 bleach solution) to prevent
transmission of bloodborne pathogens. Delaying cleaning increases exposure risk for patients and staff.
3. A fistula connects:
A. An artery to a vein
B. Two veins together
C. An artery to an artery
D. A vein to a capillary
CORRECT ANSWER A — An artery to a vein.
RATIONALE An AV fistula is created by surgically connecting an artery directly to a vein, causing arterial blood to flow into
the vein. This causes the vein to enlarge and thicken (mature), making it suitable for repeated cannulation.
4. A nephron is made up of:
A. An artery and a vein
B. A glomerulus and a tubule system
C. A cortex and medulla
D. A ureter and bladder
CORRECT ANSWER B — A glomerulus and a tubule system.
RATIONALE The nephron is the functional unit of the kidney, consisting of a glomerulus (capillary tuft that filters blood)
and a tubular system (proximal tubule, loop of Henle, distal tubule, collecting duct) that processes the filtrate
into urine.
5. A patient complains of pain at the venous needle site with swelling distal to the site and rising venous pressure. The
technician should suspect:
A. Aneurysm
B. Infection
C. An infiltration
D. Thrombosis
CORRECT ANSWER C — An infiltration.
RATIONALE Infiltration occurs when the needle pierces through the vessel wall, allowing blood to enter surrounding
tissue. Signs include pain, swelling distal to the needle site, and rising venous pressure from resistance. The
pump should be stopped immediately.
