CHT Domain 2: Machine Technology Welcome to your CHT Domain 2: Machine Technology 1. CHT: Machine Technology What is the primary role of a transducer protector in hemodialysis machines? To maintain the dialysate flow rate To protect the machine from electrical surges To prevent blood from contaminating the pressure monitoring lines To filter the dialysate for impurities None 2. CHT: Machine Technology In hemodialysis machines, what is the function of the air trap? To remove air bubbles from the blood before it returns to the patient To increase the efficiency of the dialyzer To monitor the temperature of the dialysate To regulate the flow of dialysate None 3. CHT: Machine Technology Which component in a hemodialysis machine calibrates the conductivity of dialysate? Pressure monitor Temperature sensor Conductivity meter Ultrafiltration controller None 4. CHT: Machine Technology What is the purpose of the dialysate heater in a hemodialysis machine? To sterilize the dialysate To maintain the dialysate at a preset temperature for patient comfort and treatment efficacy To increase the rate of diffusion across the dialyzer To decrease the viscosity of blood None 5. CHT: Machine Technology What component is primarily responsible for detecting blood leaks in a hemodialysis machine? Blood leak detector Hemoglobin sensor Flow meter Turbidity sensor None 6. CHT: Machine Technology What is the significance of the venous pressure monitor in a hemodialysis machine? It measures the concentration of solutes in the dialysate It controls the rate at which dialysate is pumped through the system It monitors the pressure in the venous line to detect potential blockages or leaks It regulates the temperature of the blood returning to the patient None 7. CHT: Machine Technology Which of the following is not a function of the dialysate mixing system in a hemodialysis machine? To ensure the proper mixture of dialysate concentrate and water To detect the presence of air bubbles in the dialysate To adjust the electrolyte composition of the dialysate To control the temperature of the dialysate None 8. CHT: Machine Technology What is the primary function of the dialyzer in a hemodialysis machine? To heat the dialysate To mix the dialysate solution To exchange waste products and excess fluids with the dialysate To monitor the flow of blood None 9. CHT: Machine Technology How does the arterial pressure monitor aid in the operation of a hemodialysis machine? It detects changes in the dialysate's chemical composition It ensures the dialysate is free of pyrogens It measures the pressure of blood entering the dialyzer It regulates the dose of heparin administered None 10. CHT: Machine Technology Which system in a hemodialysis machine is primarily responsible for removing pyrogens from the dialysate? The dialysate filter The ultrafiltration controller The bicarbonate mixer The conductivity meter None 1 out of 10 Time is Up! Time's up
