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

Sudden hypotension during hemodialysis is managed by placing the patient in Trendelenburg position (legs elevated) and administering a normal saline bolus to restore circulating volume. Increasing ultrafiltration would worsen hypotension.

Question 2

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

Accepted Answer

Apply direct pressure to the site with sterile gauze

Answer

Direct pressure with sterile gauze is the immediate first response to control bleeding from a vascular access site. Continuous pressure for the appropriate time is required, and the nurse must be notified.

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

Kt/V is the standard measure of dialysis adequacy. K = clearance of urea by the dialyzer, t = treatment time, V = volume of distribution of urea (total body water). A Kt/V ≥ 1.2 per treatment is the minimum recommended target.

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

Urea Reduction Ratio (URR) and Kt/V calculated from pre- and post-BUN values are the primary quality assurance tools verifying that patients received their prescribed dialysis dose.

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

Chest pain and shortness of breath are potential signs of a cardiac event or air embolism. Treatment must be stopped immediately, emergency help called, and the patient closely monitored as per emergency protocols.
