A nurse is caring for a client who has viral pneumonia. Which of the following actions should the nurse take?

A. An elevated serum calcium level (hypercalcemia) can indicate a complication of total parenteral nutrition, such as hypercalcemia resulting from excess calcium supplementation in the
TPN solution, which can lead to complications such as renal calculi and cardiac dysrhythmias.
B. The blood urea nitrogen (BUN) level within the normal range does not indicate a complication related to total parenteral nutrition.
C. The serum potassium level within the normal range does not indicate a complication related to total parenteral nutrition.
D. A normal white blood cell (WBC) count does not indicate a complication related to total parenteral nutrition.

- Choice A Rationale: The epidural PCA (patient-controlled analgesia) is designed with safety mechanisms to ensure that the patient cannot administer a dose that exceeds the prescribed safe limit. This is crucial to prevent potential overdose and complications associated with high doses of analgesics.
- Choice B Rationale: While it is true that some patients may experience reduced mobility in their legs during epidural analgesia, this is not an absolute and can vary based on the dosage and individual response. Therefore, it is not a guaranteed effect and should not be presented as such.
- Choice C Rationale: There is no conclusive evidence to suggest that epidural pain control methods shorten the second stage of labor. In fact, some studies indicate that it may actually prolong it. The primary purpose of epidural PCA is pain management, not altering the labor process timeline.
- Choice D Rationale: Postpartum headaches can be a side effect of epidural anesthesia, but they are not common to all cases. It is associated with a complication known as a post-dural puncture headache, which occurs in a minority of cases. Hence, it should not be stated as a common outcome.
