A nurse working in a rehabilitation unit is administering medications to two clients who have the same name. Which of the following identifiers should the nurse use to verify the identities of each client?

Answer: B. Loss of taste

Rationale: External radiation for throat cancer can damage the taste buds and cause loss of taste or altered taste sensation. This can affect the client's nutritional intake and quality of life. The other options are not expected findings of external radiation for throat cancer and could be caused by other factors.

Choice A reason:

"You should administer the medication at bedtime." This statement is incorrect option. Administering methylphenidate at bedtime is not appropriate because it is a stimulant medication, and taking it in the evening could interfere with the child's ability to fall asleep and disrupt their sleep pattern.

Choice Breason:

"Your child should avoid foods containing tyramine. “This statement is incorrect option. Tyramine is not a concern with methylphenidate. Tyramine is associated with certain antidepressant medications, such as MAO inhibitors. Methylphenidate is not a MAO inhibitor, so there is no need for the child to avoid tyramine-containing foods.

Choice Creason:

"You should administer the medication after breakfast." This is the correct option. Administering methylphenidate after breakfast is a common practice because it allows the child to benefit from the medication during school hours when improved attention and focus are needed the most.

Choice Dreason:

"Your child should avoid excess sodium intake." This statement is an incorrect option. Excess sodium intake is not directly related to methylphenidate use. However, it is generally a good idea for anyone, including children, to have a balanced and healthy diet, which may include monitoring sodium intake. But it is not specifically tied to the administration of methylphenidate.
