A nurse is providing preoperative teaching to a client over the phone in preparation for outpatient surgery. Which of the following information should the nurse include in the teaching?

The nurse should plan to use the client's telephone number to confirm their identity. This is because the telephone number is a unique identifier that is directly associated with the client and can be easily verified. By comparing the client's telephone number with the information on the medication administration record or electronic health record, the nurse can ensure that the right medication is given to the right patient.
Explanation:
a) The client's room number is not a reliable method to confirm the client's identity because multiple clients may be assigned to the same room, and there is a possibility of room changes or transfers.
b) The client's admitting diagnosis is not a suitable method to confirm identity as it does not provide specific information about the individual patient.
c) The name of the client's next of kin is not a reliable method to confirm the client's identity as it refers to a family member or emergency contact, not the client themselves. Additionally, next of kin information may not always be up to date or readily available.

Before administering enteral feedings via an NG tube, the nurse should check for gastric residual volume to ensure that the client is able to tolerate the feeding. If the residual volume is high, it may indicate delayed gastric emptying and the feeding may need to be delayed or the rate adjusted.

a. Encouraging the client to take sips of water may help maintain hydration, but it is not necessary prior to administering enteral feedings.

c. Flushing the tube with sterile 0.9% sodium chloride irrigation can help maintain patency of the tube, but it is not necessary prior to administering enteral feedings.

d. Encouraging the client to breathe deeply and cough can help clear secretions from the lungs, but it is not necessary prior to administering enteral feedings.
