CHBT Patient Safety and Quality Assurance 2

Question 1

Which of the following is the most critical immediate action when a patient on hemodialysis develops sudden hypotension?

Accepted Answer

Place the patient in the Trendelenburg position and administer a normal saline bolus

Answer

Increase the ultrafiltration rate to remove excess fluid faster

Answer

Disconnect the patient from the dialysis circuit immediately

Answer

Administer a vasopressor medication without notifying the nurse

Question 2

A CHBT technician notices a patient's access site is bleeding excessively after needle removal. What is the first step?

Accepted Answer

Answer

Reinsert the needle to stop the bleeding

Answer

Answer

Document the finding and wait for it to resolve on its own

Question 3

What does the term 'Kt/V' measure in hemodialysis quality assurance?

Accepted Answer

The adequacy of dialysis, specifically urea clearance relative to body water volume

Answer

The blood flow rate divided by dialysate volume

Answer

The potassium-to-volume ratio in the dialysate

Answer

The kinetics of toxin transfer across the membrane

Question 4

Which quality assurance measure helps ensure consistent delivery of the prescribed dialysis dose?

Accepted Answer

Documenting pre- and post-dialysis BUN values and calculating URR

Answer

Measuring patient weight only at the end of each session

Answer

Relying solely on patient-reported symptoms of wellness

Answer

Checking blood pressure once at the start of treatment

Question 5

During a hemodialysis treatment, a patient reports chest pain and shortness of breath. The technician should:

Accepted Answer

Stop the treatment immediately, call for emergency assistance, and monitor the patient

Answer

Slow the blood pump speed and continue treatment while observing

Answer

Increase the dialysate temperature to improve circulation

Answer

Reassure the patient and complete the session before notifying the charge nurse

Question 6

What is the purpose of a quality assurance water culture in a hemodialysis unit?

Accepted Answer

To detect bacterial contamination levels in the water used to prepare dialysate

Answer

To measure the chemical composition of the dialysate concentrate

Answer

To verify the proper functioning of the reverse osmosis membrane pressure

Answer

To confirm that chloramine levels are within acceptable pH limits
