CCHT Dialysis Procedures 3

Question 1

What is the correct action if a patient's access site begins bleeding profusely during hemodialysis?

Accepted Answer

Apply direct pressure, alert the nurse/physician, and prepare to terminate treatment

Answer

Apply a tourniquet and call for help

Answer

Increase heparin to prevent clotting

Answer

Ignore minor bleeding as it is common during dialysis

Question 2

When should the dialyzer reuse procedure begin, and what is the minimum residual volume typically required for a dialyzer to be approved for reuse?

Accepted Answer

After treatment completion and cleaning; minimum 80% of original priming volume

Answer

Immediately before the next patient; minimum 50% residual volume

Answer

24 hours after treatment; minimum 90% residual volume

Answer

Only after 10 uses; no minimum volume required

Question 3

A patient arrives 30 minutes late for a 4-hour treatment. The nurse shortens the treatment to 3.5 hours. What is the primary concern with this approach?

Accepted Answer

Inadequate dialysis (reduced Kt/V) leading to uremic symptoms and increased complications

Answer

Shortened treatment causes hypertension

Answer

Shortened treatments increase risk of access clotting

Answer

The machine cannot perform adequately in less than 4 hours

Question 4

Which assessment finding during dialysis should prompt the technician to notify the nurse immediately?

Accepted Answer

Patient reports chest pain and shortness of breath

Answer

Blood pump speed of 350 mL/min

Answer

Venous pressure of 120 mmHg

Answer

UF rate of 500 mL/hr

Question 5

What does the term sodium modeling or sodium profiling refer to in hemodialysis?

Accepted Answer

Programming the machine to vary dialysate sodium concentration during treatment to improve hemodynamic stability

Answer

Measuring the patient's serum sodium every 30 minutes

Answer

Restricting dietary sodium based on dialysis outcome data

Answer

Using high-sodium dialysate throughout treatment for all patients

Question 6

How should a CCHT respond if a patient refuses treatment at the start of a dialysis session?

Accepted Answer

Notify the nurse and physician, document the refusal, and ensure the patient understands the consequences

Answer

Proceed with treatment as prescribed because it is medically necessary
