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?
8.0
6.0
7.0
4.0
The Correct Answer is D
A. 8.0: An aspirate pH of 8.0 would indicate an alkaline substance. This would not be typical of stomach contents, which are acidic. An alkaline pH might suggest placement in the intestines or respiratory tract.
B. 6.0: While this is less alkaline than 8.0, it is still not within the typical range for stomach contents. Stomach aspirate is generally more acidic.
C. 7.0: A pH of 7.0 is neutral. Stomach contents are typically more acidic, so a neutral pH would not be consistent with correct NG tube placement in the stomach.
D. 4.0: This is within the acidic range and is consistent with the pH of stomach contents. It would be considered an indication of correct NG tube placement in the stomach.

Explanation: This level is within the normal range for random blood glucose. Hyperglycemia is usually defined by higher blood glucose levels.
C. Clammy skin
Explanation: Clammy skin is not a direct manifestation of hyperglycemia. Symptoms of hyperglycemia may include increased thirst, frequent urination, and blurred vision.

Correct Answer is D
Explanation
A. Diminished reflexes:
Explanation: Diminished reflexes are not typically associated with hypoglycemia. Instead, hypoglycemia may cause hyperactive reflexes or tremors.
B. Rapid respirations:
Explanation: Rapid respirations are not a common manifestation of hypoglycemia. In hypoglycemia, the body might respond with shallow, rapid breathing or hyperventilation.
C. Acetone breath:
Explanation: Acetone breath, often described as fruity or sweet, is associated with diabetic ketoacidosis (DKA), which is a complication of hyperglycemia rather than hypoglycemia.
D. Headache:
Explanation: Headache is a common manifestation of hypoglycemia. It can occur as a result of decreased glucose levels affecting the brain.
