Question

which action would the nurse take after contacting the primary health care provider of a post-surgical client complaining of nausea, fatigue, and a headache during the fourth hour of the infusion of total parenteral nutrition (tpn) instituted via a central venous infusion who has an hourly urine output that is twice the amount of the previous hour?
check the serum glucose level.
obtain an oxygen saturation level.
administer a prescribed analgesic.
elevate the head of the bed.

Explanation:

The client receiving total parenteral nutrition (TPN) may experience hyperglycemia. Symptoms like nausea, fatigue, headache, and increased urine output (osmotic diuresis due to high glucose levels) are concerning. Checking the serum glucose level helps confirm if hyperglycemia is the issue. Obtaining oxygen saturation is not directly related to these symptoms in this TPN - related context. Administering an analgesic only addresses the headache symptom but not the underlying cause. Elevating the head of the bed is a general comfort measure and not specific to addressing the likely metabolic problem (hyperglycemia) indicated by the client's symptoms and urine output.

Answer:

Check the serum glucose level.
