Sample Quuestions and Answers

Question 1: A Certified Clinical Hemodialysis Technician is preparing a client for a scheduled hemodialysis treatment. Before cannulating the client’s arteriovenous (AV) fistula, which assessment finding should the technician verify first to confirm that the access is functioning properly?

A. Presence of a palpable thrill and an audible bruit over the fistula

B. The client’s oral temperature is 98.6°F (37°C)

C. The client ate breakfast before arriving at the clinic

D. The blood pressure cuff fits appropriately on the upper arm

Correct Answer: A. Presence of a palpable thrill and an audible bruit over the fistula.

Explanation:
A functioning AV fistula should have both a palpable thrill (vibration) and an audible bruit (whooshing sound), indicating adequate blood flow through the vascular access. Assessing the access before cannulation helps identify potential complications such as thrombosis or stenosis that could compromise dialysis treatment. The CCHT exam frequently includes questions about vascular access assessment because maintaining a functional access is essential for safe and effective hemodialysis.

Question 2: During a hemodialysis treatment, a client suddenly becomes pale, diaphoretic, and complains of dizziness and nausea. The technician notes that the client’s blood pressure has dropped significantly from the pre-treatment reading. Which action should the technician take first?

A. Reduce ultrafiltration as directed by facility protocol, place the client in a safe position, and notify the supervising nurse.

B. Continue dialysis without making any adjustments.

C. Encourage the client to walk around the treatment area.

D. Remove the vascular access needles immediately without notifying anyone.

Correct Answer: A. Reduce ultrafiltration as directed by facility protocol, place the client in a safe position, and notify the supervising nurse.

Explanation:
The client is showing signs of intradialytic hypotension, one of the most common complications of hemodialysis. Immediate interventions include following facility protocols to reduce fluid removal, positioning the client safely, monitoring vital signs, and notifying the supervising nurse. Prompt recognition and intervention help restore hemodynamic stability and reduce the risk of injury or further complications. Patient safety is heavily emphasized on the CCHT examination.

Question 3: Which infection prevention practice is most effective in reducing the transmission of microorganisms during routine hemodialysis care?

A. Performing proper hand hygiene before and after every patient interaction.

B. Wearing gloves without performing hand hygiene.

C. Reusing disposable supplies for multiple patients.

D. Cleaning dialysis equipment only at the end of the workday.

Correct Answer: A. Performing proper hand hygiene before and after every patient interaction.

Explanation:
Hand hygiene remains the single most effective method for preventing healthcare-associated infections. Dialysis patients are particularly vulnerable to infection because of repeated vascular access procedures and chronic illness. Following proper hand hygiene guidelines, using appropriate personal protective equipment, and disinfecting equipment according to established protocols are essential responsibilities of every dialysis technician and are frequently tested on the CCHT certification exam.

Question 4: A client asks why fluid restrictions are necessary between dialysis treatments. Which response by the technician is most appropriate?

A. “Limiting fluid intake helps prevent excessive fluid buildup that can increase blood pressure and strain your heart and lungs.”

B. “Fluid restrictions are only recommended to make dialysis sessions shorter.”

C. “You may drink unlimited fluids as long as you avoid salty foods.”

D. “Fluid restrictions are necessary only during the first month of dialysis.”

Correct Answer: A. “Limiting fluid intake helps prevent excessive fluid buildup that can increase blood pressure and strain your heart and lungs.”

Explanation:
Patients receiving hemodialysis have reduced or absent kidney function and are unable to remove excess fluid effectively between treatments. Excessive fluid intake can result in hypertension, edema, pulmonary congestion, shortness of breath, and increased cardiovascular stress. Educating patients about fluid management is an important role of the dialysis team and a common topic on the CCHT certification examination.

Question 5: At the beginning of a dialysis treatment, the technician notices that the dialysate conductivity reading is outside the facility’s acceptable range. What should the technician do first?

A. Stop the initiation of dialysis and follow facility procedures to identify and correct the problem before treating the patient.

B. Begin dialysis because conductivity has little effect on patient safety.

C. Ignore the reading if the dialysis machine alarm stops.

D. Increase the blood flow rate to compensate for the abnormal conductivity.

Correct Answer: A. Stop the initiation of dialysis and follow facility procedures to identify and correct the problem before treating the patient.

Explanation:
Dialysate conductivity must remain within the prescribed range to ensure the correct electrolyte concentration is delivered during treatment. An abnormal conductivity reading may indicate a malfunction in the dialysis machine or dialysate preparation system and can place the patient at risk for serious electrolyte disturbances. Before initiating dialysis, the technician must follow established facility protocols to identify and resolve the issue. Equipment safety and quality assurance are key content areas on the CCHT exam.
