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

Choice A rationaleA 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 rationaleReceptor antagonists do not accelerate hormones attaching to cell receptor sites; they prevent this process by blocking the receptors.Choice C rationaleReceptor antagonists do not minimize the risk of other medications becoming toxic. They specifically block the action of certain endogenous substances.Choice D rationaleReceptor antagonists do not increase the action of cells; rather, they inhibit or block the usual effects.
