A nurse is in a provider's office is collecting data from an older adult client who has type 2 diabetes mellitus. Which of the following findings is a manifestation of hyperglycemia?

A. Height of the IV pole:
Explanation: The height of the IV pole is important for controlling the rate of the TPN infusion. Adjusting the height can regulate the flow rate.

B. IV insertion site:
Explanation: Monitoring the IV insertion site is crucial to assess for signs of infection, inflammation, or infiltration, which can compromise the effectiveness of TPN.

C. Manifestations of hypoglycemia:
Explanation: TPN often contains glucose, and monitoring for signs of hypoglycemia is important, as abrupt cessation of TPN can lead to low blood glucose levels.

D. The client's oral intake:
Explanation: Since the client is receiving TPN, their oral intake is not the primary source of nutrition. TPN provides essential nutrients intravenously.

A. The nurse administers the feeding through a syringe barrel by gravity.
This is an appropriate method for administering intermittent tube feedings. Gravity feeding with a syringe allows for controlled delivery of the feeding solution.

B. The nurse allows the client to rest in a supine position during feeding.
Feeding a client in a supine position is generally acceptable, especially if the client is comfortable and doesn't experience complications. However, if there are specific contraindications or concerns for aspiration, the nurse should follow the prescribed position guidelines.

C. The nurse irrigates the NG tube with tap water after feeding.
Using tap water to irrigate an NG tube is not recommended, as it may lead to complications such as electrolyte imbalances. Sterile or distilled water should be used for irrigation.

D. The nurse initiates the feeding after aspirating 50 mL of gastric residual.
This is an appropriate action. Aspirating gastric residual before initiating a feeding helps assess the presence of gastric contents, ensuring that the client is ready to receive the feeding. However, specific institutional policies may dictate the threshold for gastric residual volume that requires intervention.
