A nurse is teaching a client about a medication that has a receptor with an antagonist effect.
Which information should the nurse include in the teaching?
This medication will not change the effects of normal cellular functions.
This medication can block the usual receptor activity.
This medication will increase the effects of normal cellular functions.
This medication will increase and decrease the effects on normal cellular functions.
The Correct Answer is B
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.

Explanation
Choice A rationale
Dantrolene is used to treat malignant hyperthermia, a rare life-threatening condition usually triggered by certain anesthetics or muscle relaxants.
Choice B rationale
Although dantrolene is used to treat muscle spasticity, the indication in this question is specifically about malignant hyperthermia, making this choice not the most appropriate.
Choice C rationale
Dantrolene is not typically used for general pain management. Its primary use is in malignant hyperthermia and severe spasticity.
Choice D rationale
While reducing muscle stiffness can be a result of its spasticity treatment, malignant hyperthermia is a more specific and critical use of dantrolene.
