A nurse reviews a client's laboratory report and notes that the client's serum phosphorus (phosphate) level is 1.8 mg/dL. Which condition most likely caused this serum phosphorus level?

A. Respiratory acidosis without compensation: The pH of 7.22 indicates acidosis, but the HCO3 level of 23 mEq/L suggests that compensation is occurring because the HCO3 is within the normal range for respiratory acidosis.
B. Metabolic acidosis with full compensation: The high PaCO2 level is more indicative of respiratory issues, not metabolic acidosis. Additionally, compensation for metabolic acidosis would show elevated HCO3.
C. Respiratory acidosis with partial compensation: The elevated PaCO2 and low pH indicate respiratory acidosis. The normal HCO3 level suggests partial compensation by the kidneys.
D. Metabolic acidosis without compensation: The elevated PaCO2 and normal HCO3 suggest respiratory acidosis rather than metabolic acidosis.

Total urine output 45 mL during past 3 hours: Appropriate
Rationale: Epidural anesthesia can affect bladder function, leading to reduced urine output. A total urine output of 45 mL in 3 hours is low and should be reported as it might indicate urinary retention or decreased kidney function.
Nausea and vomiting: Inappropriate
Rationale: Nausea and vomiting are not typically a direct concern related to epidural anesthesia unless they are severe or persistent. These symptoms are more commonly associated with general anesthesia or postoperative complications, but they are not immediate concerns specific to epidural block.
Clear fluid leaking from insertion site: Appropriate
Rationale: Clear fluid leaking from the epidural insertion site could indicate cerebrospinal fluid leakage or other complications. This should be reported immediately to assess for potential complications such as an epidural hematoma or infection.
Severe headache: Appropriate
Rationale: A severe headache following an epidural block could be a sign of a post-dural puncture headache, which is a known complication of epidural anesthesia. It should be reported to the healthcare provider for further evaluation and management.
Left knee pain 3 out of 10: Inappropriate
Rationale: Pain at a level of 3 out of 10 is relatively mild and may be expected following surgery. While it is important to monitor and manage pain, this level of pain is not usually an immediate concern related to the epidural anesthesia unless other symptoms are present.
