1What is the primary purpose of assessing a patient's weight before and after hemodialysis?
A.To determine their nutritional status.
B.To calculate the amount of fluid to be removed.
C.To adjust their medication dosage.
D.To monitor for signs of infection.
Explanation: Assessing a patient's weight before and after hemodialysis is crucial for determining the amount of excess fluid that needs to be removed during the treatment. This is also known as the ultrafiltration goal.
2Which of the following is a critical step in preparing the hemodialysis machine before initiating treatment?
A.Priming the dialyzer and bloodlines with saline.
B.Calibrating the patient's blood pressure cuff.
C.Ensuring the patient has a comfortable chair.
D.Preparing a post-dialysis snack for the patient.
Explanation: Priming the dialyzer and bloodlines with saline is a critical step in preparing the hemodialysis machine. This process removes any air and sterilants from the system, ensuring patient safety.
3What is the acceptable level of chlorine in the water used for hemodialysis?
A.Less than 0.1 ppm
B.Less than 0.5 ppm
C.Less than 1.0 ppm
D.Less than 5.0 ppm
Explanation: The acceptable level of chlorine in the water used for hemodialysis is less than 0.1 ppm. Higher levels of chlorine can cause hemolysis, a dangerous condition where red blood cells are destroyed.
4Which of the following is the most important practice for preventing the transmission of infection in a hemodialysis unit?
A.Wearing a new gown for each patient.
B.Hand hygiene before and after patient contact.
C.Using a new needle for each cannulation.
D.Disinfecting the patient's chair after each use.
Explanation: Hand hygiene is the single most important practice for preventing the transmission of infection in any healthcare setting, including hemodialysis units. It should be performed before and after any patient contact.
5A patient on hemodialysis develops hypotension. What is the most appropriate initial intervention?
A.Administer a bolus of hypertonic saline.
B.Decrease the ultrafiltration rate.
C.Increase the blood flow rate.
D.Place the patient in an upright position.
Explanation: Hypotension during hemodialysis is often caused by excessive fluid removal. Decreasing the ultrafiltration rate is the most appropriate initial intervention to reduce the rate of fluid removal and allow the patient's blood pressure to stabilize.
6What does the term 'dry weight' refer to in the context of hemodialysis?
A.The patient's weight before starting a dialysis session.
B.The patient's target weight after a dialysis session, representing their normal fluid status.
C.The weight of the dialyzer before use.
D.The total weight of fluid removed during a dialysis session.
Explanation: 'Dry weight' is the patient's ideal post-dialysis weight, where they are free of excess fluid and their blood pressure is normal. It is a target set by the physician.
7What is the function of the dialysate in hemodialysis?
A.To remove waste products from the blood.
B.To add electrolytes and minerals to the blood.
C.To carry waste products away from the dialyzer.
D.All of the above.
Explanation: The dialysate is a solution that helps remove waste products from the blood, can add necessary electrolytes and minerals, and carries the removed waste products away from the dialyzer.
8What is the purpose of the reverse osmosis (RO) system in a hemodialysis water treatment facility?
A.To remove chlorine and chloramines from the water.
B.To remove bacteria and endotoxins from the water.
C.To soften the water by removing calcium and magnesium.
D.To remove dissolved salts and other impurities from the water.
Explanation: The reverse osmosis (RO) system is the primary component of a hemodialysis water treatment facility. It uses a semipermeable membrane to remove dissolved salts, organic compounds, and other impurities from the water, ensuring it is safe for use in dialysis.
9What is the primary purpose of reprocessing a dialyzer?
A.To save money on the cost of new dialyzers.
B.To reduce the amount of medical waste.
C.To clean, disinfect, and test the dialyzer for reuse by the same patient.
D.To sterilize the dialyzer for use by any patient.
Explanation: The primary purpose of reprocessing a dialyzer is to ensure it is clean, disinfected, and functioning properly for reuse by the same patient. This is done to ensure patient safety and the effectiveness of the treatment.
10A patient on hemodialysis complains of muscle cramps. Which of the following is the most likely cause?
A.Hypokalemia
B.Hypercalcemia
C.Rapid fluid and electrolyte shifts
D.An allergic reaction to the dialyzer
Explanation: Muscle cramps during hemodialysis are most commonly caused by rapid fluid and electrolyte shifts, particularly the removal of sodium. This can lead to muscle irritability and cramping.
