A nurse is preparing to administer an intermittent enteral feeding through a small-bore NG tube. Which of the following actions should the nurse take before initiating the feeding?
Flush the tube with 5 mL of water.
Test the pH of fluid aspirated from the tube.
Inject air through the tubing and auscultate for gurgling sounds:
Change the bag and tubing system every 12 hr
The Correct Answer is B
A. Flush the tube with 5 mL of water:
Explanation: Flushing the tube with water is a routine practice before and after administering medications or feedings to maintain tube patency. However, it is not the primary action to confirm tube placement.
B. Test the pH of fluid aspirated from the tube (Correct Answer):
Explanation: Testing the pH of aspirated fluid helps confirm that the tube is in the stomach. A pH between 1 and 5 is generally indicative of gastric placement.
C. Inject air through the tubing and auscultate for gurgling sounds:
Explanation: This method is an older practice and is not recommended as a reliable method for verifying tube placement. Testing the pH is a more accurate and preferred method.
D. Change the bag and tubing system every 12 hr:
Explanation: Changing the bag and tubing system every 12 hours is a routine practice to maintain the integrity of the enteral feeding system. However, it is not specifically related to the initial steps in verifying tube placement.

Correct Answer is A
Explanation
A. Fidelity refers to the concept of keeping promises or commitments made to clients. In this scenario, the nurse is demonstrating fidelity by informing the client that they will return as soon as possible with pain medication, indicating a commitment to addressing the client's needs promptly.
B. Justice pertains to fairness and equitable distribution of resources. It is not demonstrated in this scenario where the nurse is making a commitment to address the client's pain.
C. Autonomy involves respecting the client's right to make their own decisions and choices about their care. The nurse, in this case, is not specifically addressing the client's autonomy but rather demonstrating fidelity by committing to providing pain medication.
D. Nonmaleficence is the principle of doing no harm and ensuring the client's safety. While providing pain medication aligns with nonmaleficence by addressing the client's pain, the specific action of informing the client about the intent to return promptly falls more under the principle of fidelity.
Correct Answer is ["0.5"]
Explanation
To calculate the volume (mL) that the nurse should administer, you can use the following formula:
Volume (mL) = Dose (mg)/Concentration (mg/mL)
In this case:
- Volume =25 mg/50 mg/mL
- Volume=0.5mL
Therefore, the nurse should administer 0.5 mL of promethazine for the 25 mg IM dose, rounded to the nearest tenth.
