CCHT Dialysis Procedures 2

Question 1

What is the correct sequence for initiating hemodialysis using a central venous catheter (CVC)?

Accepted Answer

Clamp lines, remove caps aseptically, aspirate and discard blood/heparin, then connect blood lines

Answer

Connect blood lines, then remove caps and aspirate clots

Answer

Open the catheter, flush with saline, then connect without aspiration

Answer

Remove the dressing, clean the site, then attach blood lines directly

Question 2

A patient develops muscle cramps during hemodialysis. What is the most appropriate initial intervention?

Accepted Answer

Reduce ultrafiltration rate and administer a small normal saline bolus

Answer

Discontinue treatment immediately

Answer

Increase blood pump speed

Answer

Apply heat packs to the affected muscles

Question 3

What is the recommended approach when a patient's arterial pressure alarm activates with a very negative reading (e.g., -250 mmHg)?

Accepted Answer

Reduce the blood pump speed and check for arterial access problems

Answer

Ignore it if the patient feels fine

Answer

Increase the blood pump speed to overcome the resistance

Answer

Stop treatment and remove the patient immediately

Question 4

How should a hemodialysis treatment be terminated at the end of a session using the saline rinse-back method?

Accepted Answer

Connect saline to the arterial line, rinse blood back to the patient, then remove needles

Answer

Stop the pump and clamp all lines simultaneously

Answer

Remove needles first, then drain blood from the circuit

Answer

Stop the blood pump and leave lines attached until blood clots

Question 5

What is the purpose of recirculation assessment during hemodialysis, and when would it occur?

Accepted Answer

It occurs when returned blood immediately re-enters the arterial needle, reducing treatment efficiency

Answer

Recirculation is normal and indicates the fistula is working

Answer

Recirculation means the dialyzer is removing too much waste

Answer

It is a technique to improve clearance of large molecules

Question 6

During needle removal after hemodialysis, what is the correct method to achieve hemostasis at the needle sites?

Accepted Answer

Apply firm digital pressure with gauze for 5 to 10 minutes without releasing

Answer

Apply a tourniquet above the access site

Answer

Use sutures to close the needle site

Answer

Apply ice immediately to constrict blood vessels
