Final answer:
The nurse administering total parenteral nutrition must immediately attend to a blood glucose level of 350 mg/dl, as it indicates potential hyperglycemia, a serious complication of this therapy.
Step-by-step explanation:
The nurse is administering the initial total parenteral nutrition solution to a client. Of the assessments listed, Blood glucose of 350 mg/dl requires the nurse's immediate attention. This elevated level could indicate hyperglycemia, which is a common but potentially serious complication of total parenteral nutrition (TPN). TPN solutions are high in glucose, and frequent monitoring of blood glucose levels is essential to prevent and manage hyperglycemic episodes. The other assessments, while important, are not as immediately concerning as the high blood glucose level. A temperature of 37.5 degrees Celsius is slightly elevated but not alarming, a urine output of 300 cc in 4 hours is within the normal range for adult clients, and poor skin turgor may indicate dehydration, which should be addressed but is not as critical as the hyperglycemia.
