A patient with chronic renal failure is to begin renal dialysis treatment and asks for advice about which type of dialysis would be best. The patient is considering peritoneal dialysis because it is less expensive and has fewer dietary and fluid restrictions. What is the most accurate information for the nurse to provide about peritoneal dialysis?
It gives more independence and more closely resembles normal kidney function.
It has literally no drawbacks.
It usually does not work very well and has many complications, such as a high blood sugar level.
It is a lot more work than hemodialysis, in which the health care staff takes care of everything.
The Correct Answer is A
A. It gives more independence and more closely resembles normal kidney function: Peritoneal dialysis allows patients to manage treatment at home, providing more flexibility and independence, and it mimics the kidney's natural filtration process.
B. It has literally no drawbacks: While peritoneal dialysis has benefits, potential complications include peritonitis, catheter infections, and hyperglycemia from the dialysis solution.
C. It usually does not work very well and has many complications, such as a high blood sugar level: While hyperglycemia can occur, this exaggerates the risks and misrepresents the effectiveness of peritoneal dialysis.
D. It is a lot more work than hemodialysis, in which the health care staff takes care of everything: While it requires self-management, the workload depends on individual circumstances and training.

Correct Answer is B
Explanation
A. Blood volume decreases: While fluid imbalances are common in renal failure, the oliguric stage is marked by fluid retention, not decreased blood volume.
B. Blood urea nitrogen (BUN) level rises: The oliguric stage is characterized by reduced urine output, leading to waste product accumulation, including elevated BUN levels.
C. Urine osmolality increases: In renal failure, urine osmolality may remain low or not reflect changes due to impaired kidney function.
D. Serum calcium increases: Serum calcium often decreases in renal failure due to disturbances in vitamin D metabolism and phosphate retention.
Correct Answer is D
Explanation
A. Equal to the excretion of urea: Urea excretion contributes to osmolality but does not define it.
B. In a ratio of 10:1 with the serum: This is not a recognized ratio for urine and serum osmolality.
C. Approximately half of the serum: In a healthy kidney, urine osmolality may vary but typically equals serum osmolality in a state of balance.
D. Equal to the osmolality of the serum: Under normal conditions, the kidney regulates urine osmolality to maintain a balance with serum osmolality, reflecting adequate kidney function.
