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.
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 means residual chemical remains. The machine must be rinsed 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 wastes. BUN, creatinine, and phosphorus accumulate. 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) is the patient's lifeline for hemodialysis.
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 surgically connects an artery to a vein, most commonly in the forearm. It uses native vessels, not
synthetic material.
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 provides immediate detection of membrane rupture but does not quantify blood loss
or identify blood type.
