A nurse is teaching about safe handling of formula to a client who is postpartum and chooses to bottle feed her newborn.
Which of the following statements by the client indicates an understanding of the teaching?

Choice A rationale:

The nurse should use the client's telephone number or another unique identifier, such as a medical record number or a unique identification code, to confirm the client's identity before administering medication. Using a telephone number or a unique identifier ensures accurate identification of the client and helps prevent medication errors.

Choice B rationale:

Place of birth is not a suitable identifier for confirming a client's identity. It does not provide specific and accurate information about the individual and may not be unique to the client.

Choice C rationale:

Driver license number is not a suitable identifier for confirming a client's identity. It may not be readily available in the healthcare setting, and not all clients have a driver's license. Using this identifier could lead to identification errors.

Choice D rationale:

Room number is not a suitable identifier for confirming a client's identity. Room numbers are not unique to individual clients and can change based on hospital assignments. Relying on room numbers can lead to confusion and medication errors.

Aspirate contents from the tube and verify the pH level.

• A. This is an incorrect action. Inserting air in the tube and listening for gurgling sounds in the epigastric area is not a reliable method to confirm NG tube placement, as it can produce falsepositive results due to air entering the stomach or intestines.
• B. This is a correct action. Aspirating contents from the tube and verifying the pH level is a valid method to confirm NG tube placement, as gastric contents typically have a pH of less than 5.5, while intestinal or respiratory contents have a higher pH.
• C. This is an incorrect action. Reviewing the medical record for previous x-ray verification of placement is not sufficient to confirm NG tube placement, as the tube can migrate or become dislodged after insertion. X-ray verification should be done initially and whenever there is doubt about the tube's position.
• D. This is an incorrect action. Auscultating the lungs for adventitious breath sounds is not a specific method to confirm NG tube placement, as it can indicate other conditions such as pneumonia or pulmonary edema. It can also miss signs of respiratory complications due to NG tube misplacement, such as pneumothorax or bronchial obstruction.
