Question 1

Which of the following best describes the reason for wearing gloves when handling a machine prior to blood?

Accepted Answer

Universal precautions

Answer

Universal precautions are an infection control strategy that treats all human blood and certain body fluids as if they are known to be infectious for HIV, HBV, and other bloodborne pathogens. Wearing gloves when handling equipment, even before blood is present, adheres to this principle by protecting the technician from potential exposure to unseen contaminants or residual bodily fluids from previous use. This proactive measure minimizes the risk of pathogen transmission in a healthcare setting.

Question 2

You test for sterilant levels in a hemodialysis machine prior to patient use. The test is positive for sterilant. This means the machine:

Accepted Answer

needs further rinsing

Answer

A positive test for sterilant indicates that residual sterilizing chemicals are still present in the machine. These chemicals are toxic and can cause severe adverse reactions if they enter the patient's bloodstream during dialysis. Therefore, the machine requires thorough rinsing to remove all traces of the sterilant before it can be safely connected to a patient.

Question 3

Prior to each patient shift, it would be essential to perform a water quality check for which of these substances?

Accepted Answer

Chlorine and chloramine

Answer

Chlorine and chloramine are disinfectants added to municipal water supplies, but they are highly toxic to dialysis patients and can cause hemolytic anemia. Therefore, it is critical to test for their presence and ensure they are completely removed by the carbon filters before each patient shift. This daily check is a vital safety measure to prevent patient harm.

Question 4

During hemodialysis, a patient goes into cardiac arrest. Which of these actions should be taken first?

Accepted Answer

Call for help

Answer

In any medical emergency, especially a life-threatening event like cardiac arrest, the immediate priority is to activate the emergency response system and call for help. This ensures that trained personnel and necessary equipment (like a defibrillator) arrive quickly to initiate resuscitation efforts. While other actions like stopping ultrafiltration or returning blood may be necessary, they are secondary to securing immediate assistance.

Question 5

The technician's role in patient teaching should be to:

Accepted Answer

determine the patient's learning needs

Answer

While technicians reinforce teaching, their primary role in patient education is to assess and determine what specific information the patient needs to learn or understand regarding their treatment and self-care. This involves identifying gaps in knowledge, addressing concerns, and tailoring information to the patient's individual comprehension level. This foundational step ensures that teaching efforts are relevant and effective.
