A nurse is teaching a client about a medication that has a receptor antagonist effect.Which information should the nurse include in the teaching?

This medication will block the effects of normal cellular functions.

This medication will accelerate hormones in your body from attaching to cell receptor sites.

This medication minimizes the risk that other medications you take become toxic.

This medication will increase the cells in your body from performing certain actions.

Answer and Explanation

The Correct Answer is A

Choice A rationale

A receptor antagonist blocks the effects of normal cellular functions by binding to receptor sites and preventing endogenous substances (like hormones or neurotransmitters) from activating those receptors.

Choice B rationale

Receptor antagonists do not accelerate hormones attaching to cell receptor sites; they prevent this process by blocking the receptors.

Choice C rationale

Receptor antagonists do not minimize the risk of other medications becoming toxic. They specifically block the action of certain endogenous substances.

Choice D rationale

Receptor antagonists do not increase the action of cells; rather, they inhibit or block the usual effects.
