A nurse is providing education to a client who will be starting peritoneal dialysis. The client asks, "How does peritoneal dialysis work?" Which of the following responses by the nurse is accurate?
"Peritoneal dialysis uses a machine to filter blood outside of your body."
"Peritoneal dialysis involves the removal of the peritoneal membrane to filter waste."
"Peritoneal dialysis uses the peritoneal membrane in your abdomen to filter waste."
"Peritoneal dialysis requires a catheter to be inserted into your bladder to remove toxins."
The Correct Answer is C
A) This statement is incorrect. Peritoneal dialysis does not use a machine to filter blood outside of the body; that description is characteristic of hemodialysis.
B) This statement is incorrect. Peritoneal dialysis does not involve the removal of the peritoneal membrane; instead, it uses the peritoneal membrane in the abdomen to filter waste.
C) This statement is accurate. Peritoneal dialysis uses the peritoneal membrane in the abdomen as a semipermeable membrane to filter waste products and excess fluids from the blood.
D) This statement is incorrect. Peritoneal dialysis does not require a catheter to be inserted into the bladder. Instead, it uses a catheter to infuse and drain dialysate into and out of the peritoneal cavity.

Correct Answer is C
Explanation
A) This statement is incorrect. Serum calcium levels are not directly related to ESA therapy for anemia management. ESA therapy focuses on increasing red blood cell production.
B) This statement is incorrect. Blood urea nitrogen (BUN) levels are indicators of kidney function and may be monitored for other reasons in a client on hemodialysis. However, they are not directly related to ESA therapy for anemia management.
C) This statement is accurate. During ESA therapy, the nurse should closely monitor the client's hemoglobin and hematocrit levels. ESAs stimulate the production of red blood cells and can increase hemoglobin and hematocrit levels. Regular monitoring is essential to prevent anemia or excessive increases in these values.
D) This statement is incorrect. Serum potassium levels may be monitored for a client on hemodialysis due to the potential for electrolyte imbalances, but they are not the primary concern during ESA therapy for anemia management.
Correct Answer is C
Explanation
A) This statement is incorrect. Increasing the rate of fluid removal during dialysis may worsen the client's symptoms of lightheadedness and dizziness, as it can lead to further drops in blood pressure.
B) This statement is incorrect. Administering an antihypertensive medication is not appropriate in this situation, as the client is experiencing symptoms of low blood pressure, not high blood pressure.
C) This statement is accurate. Feeling lightheaded and dizzy during hemodialysis may be a sign of hypotension (low blood pressure), and the nurse should assess the client's blood pressure and pulse rate to determine if intervention is needed.
D) This statement is incorrect. Elevating the client's legs may promote blood flow, but it does not address the immediate issue of lightheadedness and dizziness. Assessing the client's blood pressure and pulse rate is the priority to determine the appropriate intervention.
