CCHT PRACTICE EXAMINATION Questions 1 – 50
1. Which of the following best describes the reason for wearing gloves when handling machine prior to blood?
A. Patient comfort.
B. Asepsis.
C. Universal precautions.
D. HIV.
CORRECT ANSWER C — Universal precautions.
RATIONALE Universal (standard) precautions require gloves for any potential contact with blood or body fluids, protecting
both patient and technician from bloodborne pathogens.
2. You test for sterilant levels in a hemodialysis machine prior to patient use. The test is positive for sterilant. This
means the machine:
A. Is sterile and bacteria free.
B. Needs further rinsing.
C. Needs more sterilant.
D. Is in conductivity.
CORRECT ANSWER B — Needs further rinsing.
RATIONALE A positive sterilant test indicates residual chemical disinfectant remains in the machine. The machine must be
rinsed further until the test is negative before patient use.
, 3. Choose the correct statement regarding serum abnormalities in renal failure:
A. Creatinine, BUN, and phosphorus are elevated.
B. Creatinine, BUN, and phosphorus are depressed.
C. Calcium and bicarbonate are elevated.
D. Calcium and bicarbonate are depressed.
CORRECT ANSWER A — Creatinine, BUN, and phosphorus are elevated.
RATIONALE In renal failure, the kidneys cannot excrete waste products, so BUN, creatinine, and phosphorus accumulate
in the blood. Calcium and bicarbonate are typically low.
4. Hemodialysis requires a means to channel the patient's blood to the hemodialyzer and then back to the body. It's
called:
A. Vascular access.
B. Hemodialyzer.
C. Dialyzing fluid delivery system.
D. Infusion pump.
CORRECT ANSWER A — Vascular access.
RATIONALE Vascular access (fistula, graft, or catheter) provides the means to remove and return blood during
hemodialysis. It is the patient's lifeline.
5. Which of the following is correct regarding a fistula?
A. Usually created in the leg, near the ankle.
B. Usually created in the forearm, near the wrist.
C. Are made of Silastic tubing.
D. None of the above.
CORRECT ANSWER B — Usually created in the forearm, near the wrist.
RATIONALE An AV fistula is created by surgically connecting an artery to a vein, most commonly in the forearm near the
wrist (radiocephalic). It uses the patient's own vessels, not synthetic tubing.
6. Blood leak detectors are extremely sensitive and can determine:
A. Blood type.
B. Amount of blood loss.
C. Blood leakage immediately.
D. Volume changes.
CORRECT ANSWER C — Blood leakage immediately.
RATIONALE The blood leak detector monitors dialysate outflow for the presence of blood, indicating a membrane
rupture. It provides immediate detection but does not measure amount or type.
