A nurse is caring for a client who is receiving peritoneal dialysis. The nurse should monitor the client for which of the following manifestations of peritonitis?

Choice A reason: A BUN level of 8 mg/dL and a creatinine level of 0.7 mg/dL are within normal ranges for healthy individuals. In CKD, BUN and creatinine levels are typically elevated due to decreased kidney function.

Choice B reason: A BUN level of 45 mg/dL is elevated, which could be expected in CKD, but a creatinine level of 8 ng/dL is not correctly expressed. Creatinine is measured in mg/dL, and in CKD, it would be higher than normal, not lower.

Choice C reason: A BUN level of 10 mg/dL and a creatinine level of 0.3 mg/dL are both lower than what would typically be expected in a patient with CKD. CKD usually results in higher levels due to reduced kidney function.

Choice D reason: A BUN level of 23 mg/dL and a creatinine level of 1.0 mg/dL are more aligned with what might be expected in CKD. Normal BUN levels range from 7 to 20 mg/dL, and normal creatinine levels can vary based on age, sex, and body size. In CKD, both levels tend to be higher as the kidneys' ability to filter blood decreases.

Choice A reason: In acute kidney injury (AKI), the blood urea nitrogen (BUN) level is expected to be elevated due to the kidneys' impaired ability to excrete urea, which is a waste product of protein metabolism. Normal BUN levels range from approximately 7 to 20 mg/dL.

Choice B reason: Hypercalcemia is not commonly associated with AKI. Instead, patients with AKI may experience hypocalcemia due to the kidneys' reduced ability to convert vitamin D to its active form, which is necessary for calcium absorption.

Choice C reason: Metabolic alkalosis is not a typical finding in AKI. More commonly, patients with AKI experience metabolic acidosis because the kidneys are unable to excrete acid effectively, leading to an accumulation of acid in the body.

Choice D reason: Hypokalemia is generally not expected in AKI. The condition is more often associated with hyperkalemia, as the impaired kidney function leads to a reduced excretion of potassium, which can accumulate to dangerous levels.
