A nurse is caring for an 8-year-old male client admitted to the surgical unit after having a total right knee replacement.
The nurse reviews the client's nursing note, vital signs, and medication administration record (MAR). Based on the findings, which medication is considered an anti-emetic?

Choice A rationale

Not giving the medication and notifying the provider can cause unnecessary delays in treatment.

Choice B rationale

Administering the medication without checking the expiration date can result in administering an ineffective or harmful medication.

Choice C rationale

There is no need to notify the provider if the medication is already prescribed and not expired.

Choice D rationale

Checking the medication's expiration date ensures the medication is safe to administer and effective.

Choice A rationale

This statement is incorrect because an antagonist medication changes the effects of normal cellular functions by blocking receptors.

Choice B rationale

An antagonist medication binds to receptors and blocks the usual receptor activity, preventing the normal action of the endogenous substance.

Choice C rationale

This statement describes an agonist medication, which binds to receptors and increases the effects of normal cellular functions.

Choice D rationale

This statement is incorrect because an antagonist medication does not both increase and decrease the effects on normal cellular functions; it primarily blocks receptor activity.
