FREE Dialysis Procedures Questions and Answers

Question 1

What is the first step in preparing a dialysis machine for treatment?

Accepted Answer

Check the machine settings and perform safety checks

Answer

Before connecting a patient to the dialysis machine, ensuring its proper and safe operation is paramount. This involves verifying all machine settings, performing necessary safety checks, and confirming alarm functionality. This critical first step prevents potential harm to the patient and guarantees that the treatment will be delivered accurately and effectively according to the prescription.

Question 2

What is the typical duration of a hemodialysis treatment?

Accepted Answer

3 to 5 hours

Answer

Hemodialysis treatments typically last 3 to 5 hours, performed three times a week. This duration is necessary to allow sufficient time for the dialyzer to effectively remove accumulated waste products, toxins, and excess fluid from the patient's blood. The specific duration is tailored to the individual patient's needs, kidney function, and fluid status to achieve optimal clearance.

Question 3

Which parameter is **most critical** to monitor during a dialysis session?

Accepted Answer

Blood pressure

Answer

Blood pressure is the most critical parameter to monitor because rapid fluid removal during dialysis can cause significant drops, leading to hypotension, dizziness, and fainting. Maintaining stable blood pressure is vital for patient safety and comfort, preventing complications like organ hypoperfusion. Frequent monitoring allows for timely interventions, such as adjusting ultrafiltration or administering saline, to stabilize the patient.

Question 4

What is the purpose of the dialyzer in a hemodialysis machine?

Accepted Answer

Filters waste and excess fluid from the blood

Answer

The dialyzer, often referred to as the 'artificial kidney,' is the central component of the hemodialysis machine. It contains a semi-permeable membrane that filters waste products like urea, creatinine, and excess electrolytes, along with excess fluid, from the patient's blood into the dialysate solution. This process effectively mimics the filtering function of healthy kidneys, purifying the blood.

Question 5

What must be done before disconnecting a patient from dialysis?

Accepted Answer

Return the patient's blood and remove needles

Answer

Before disconnecting, it is crucial to return all the patient's blood from the extracorporeal circuit (bloodlines and dialyzer) back into their body to prevent blood loss. Once the blood return is complete, the needles can be safely removed from the vascular access site. This sequence ensures patient safety and minimizes complications such as bleeding or air embolism.
