I need help plz! A is my answer
After reading the website I still think the answer is (a) is this correct?
To determine the correct answer, let's go through each option and eliminate the incorrect ones:
A. hemodialysis takes longer than peritoneal dialysis.
This statement is not accurate. Hemodialysis typically takes about 3-4 hours per treatment session, which needs to be performed three times a week. Peritoneal dialysis, on the other hand, is done continuously throughout the day and doesn't require as much time per session. Therefore, option A is incorrect.
B. peritoneal dialysis involves the removal of blood from the patient.
This statement is also incorrect. In peritoneal dialysis, a special fluid is introduced into the abdominal cavity through a catheter. The peritoneum, a membrane in the abdomen, acts as the filter to remove waste and excess fluids from the blood. The fluid is then drained out, but no blood is directly removed from the patient. Therefore, option B is incorrect.
C. hemodialysis is a step closer to the need for transplantation compared with peritoneal dialysis.
This statement is partially correct. Hemodialysis and peritoneal dialysis are both treatment options for kidney failure, but the chances of needing a kidney transplant could be higher for patients on hemodialysis. Hemodialysis is more likely to be used as a bridge to transplantation because it is a more intensive and higher risk treatment option. Peritoneal dialysis, on the other hand, can be used for a longer duration and may have better long-term outcomes, potentially reducing the need for transplantation. Therefore, option C can be considered correct.
D. peritoneal dialysis doesn't need a dialyzer to work, whereas hemodialysis does.
This statement is also correct. In peritoneal dialysis, the peritoneal membrane acts as the dialyzer. The peritoneal cavity acts as a semi-permeable membrane, allowing the exchange of waste and fluid between the blood vessels and the dialysate fluid. Hemodialysis, on the other hand, requires the use of a dialyzer, which is an external device that acts as an artificial kidney to filter the blood. Therefore, option D is correct.
So, the correct answer is both C and D.
