CCHT Domain 2: Technical Welcome to your CCHT Domain 2: Technical 1. CCHT: Technical What is the primary action to take if a patient exhibits signs of air embolism during dialysis? Increase the blood flow rate Place the patient in a supine position Turn the patient onto their left side and lower the head Administer oxygen at a high concentration None 2. CCHT: Technical During dialysis, a sudden increase in the transmembrane pressure (TMP) indicates: A decrease in dialysate flow A blood leak in the dialyzer Clotting within the dialyzer An increase in blood flow rate None 3. CCHT: Technical Which of the following conditions is most likely to cause dialyzer reuse syndrome? Insufficient rinsing of the dialyzer High bicarbonate dialysate Use of a high-flux dialyzer Incorrect blood flow rate None 4. CCHT: Technical What is the most appropriate response if the dialysis machine alarms for a high venous pressure repeatedly? Decrease the dialysate flow rate Check for and remove any kinks in the venous line Increase the anticoagulant dosage Adjust the temperature of the dialysate None 5. CCHT: Technical When preparing a dialysis machine, what is the importance of conducting a pressure test on the dialyzer? To determine the appropriate dialysate composition To ensure there are no leaks and the membrane integrity is intact To calibrate the dialysis machine's temperature settings To assess the efficiency of the dialyzer's urea removal None 6. CCHT: Technical In hemodialysis, what is the purpose of using a sodium modeling profile? To decrease the risk of dialysis-induced hypotension To increase the efficiency of phosphate removal To prevent blood from clotting in the dialyzer To enhance the removal of potassium None 7. CCHT: Technical Why is it important to monitor the conductivity of dialysate during dialysis? To ensure proper temperature regulation To detect the presence of endotoxins To verify the correct concentration of electrolytes To monitor the removal rate of urea None 8. CCHT: Technical What does a negative dialysate culture indicate in the context of hemodialysis? The dialyzer is functioning correctly There is an absence of bacterial contamination in the dialysate The patient is not at risk for air embolism The conductivity of the dialysate is within acceptable limits None 9. CCHT: Technical When a patient experiences cramping during dialysis, the initial step should be: Increase the blood flow rate Administer a bolus of normal saline Adjust the dialysate calcium concentration Decrease the dialysate temperature None 10. CCHT: Technical What is the primary concern when the Kt/V value is significantly lower than recommended levels? The dialysis session length is too short The patient's blood pressure is too high The dialyzer reuse process is ineffective There is an increased risk of infection None 11. CCHT: Technical For ensuring patient safety, what is the significance of calculating urea reduction ratio (URR) in hemodialysis? It helps in adjusting the heparin dosage It is used to measure the effectiveness of dialysis It determines the correct dialysate composition It prevents air embolism during dialysis None 12. CCHT: Technical What is the best practice for addressing a high potassium level in dialysate? Decrease the dialysate flow rate Adjust the dialysate potassium concentration to a lower level Increase the temperature of the dialysate Increase the bicarbonate concentration in the dialysate None 13. CCHT: Technical In the context of water treatment for hemodialysis, what is the primary purpose of using ultraviolet light systems? To soften the water by removing calcium and magnesium To increase the pH of the water To disinfect the water by killing bacteria and viruses To remove chlorine and chloramines from the water None 14. CCHT: Technical What does an increase in the delta pressure across a dialyzer indicate? A decrease in the efficiency of solute removal An improvement in the dialyzer's performance Clot formation or fouling within the dialyzer A need for adjustment in the dialysate composition None 15. CCHT: Technical The correct response to a detected blood leak in the dialysis system is: Continue the dialysis session while monitoring the patient closely Terminate the dialysis session and replace the dialyzer and lines Increase the anticoagulant dose to prevent further clotting Adjust the dialysate electrolyte composition None 16. CCHT: Technical Why is it important to monitor the air detector during hemodialysis? To ensure the dialysis machine is adequately powered To detect the presence of air in the blood circuit, preventing air embolism To check the temperature of the dialysate To measure the blood flow rate None 17. CCHT: Technical What is the significance of adjusting the bicarbonate concentration in the dialysate? To control the patient's body temperature during dialysis To enhance the removal of middle molecules To correct acid-base imbalances in the patient To increase the dialysate flow rate None 18. CCHT: Technical What precaution should be taken when using high-flux dialyzers? The dialysis session should be shortened Anticoagulation must be closely monitored The dialysate calcium concentration should be increased Blood flow rates should be reduced None 19. CCHT: Technical The occurrence of dialyzer clotting is most likely influenced by: Inadequate dialysate conductivity Low temperature of the dialysate Insufficient anticoagulation High dialysate flow rates None 20. CCHT: Technical What is the role of the proportional pump system in a dialysis machine? To maintain the patient's blood pressure within normal ranges To ensure the accurate mixing of dialysate concentrate with water To control the temperature of the dialysate To regulate the flow of blood through the dialyzer None 1 out of 20 Time is Up!
