A nurse is caring for a client who requires an NG tube. After inserting the tube, the nurse tests the pH of the client's aspirate. Which of the following pH levels should the nurse identify as an indication of correct placement of the tube?

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. Using the ball of the finger (the fleshy part) is not recommended as it can lead to more pain and discomfort. The side of the fingertip is generally preferred for less discomfort and more accurate results.

B. Avoids using the fingers of her dominant hand as puncture sites:While it's generally recommended to avoid using the fingers of your dominant hand for frequent blood glucose monitoring, it's not always necessary. The client can still obtain accurate readings from her dominant hand if she rotates puncture sites.

C. Using the side of the fingertip is a recommended practice. The side of the fingertip has fewer nerve endings than the pad of the finger, which helps reduce discomfort. This technique is commonly used for more accurate and less painful blood glucose testing.

D. Avoids using the thumbs as puncture sites:
Using thumbs as puncture sites is generally avoided because they might have thicker skin and could yield less accurate blood samples. Therefore, avoiding thumbs for blood glucose testing is a good practice.
