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.

Answer and Explanation

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.

Correct Answer is B

Explanation

Choice A rationale

Insulin is a medication used to manage blood sugar levels in clients with diabetes. It is not appropriate for the management of deep vein thrombosis (DVT) as it has no anticoagulant properties.

Choice B rationale

Warfarin (Coumadin) is an oral anticoagulant commonly prescribed for the long-term management of DVT. It is suitable for clients who are unable to self-administer injections, making it a practical option for discharge.

Choice C rationale

Heparin is an anticoagulant that is typically administered via injection or IV. For clients unable to self-inject at home, it is not the best choice for managing DVT after discharge.

Choice D rationale

Enoxaparin (Lovenox) is a low-molecular-weight heparin that is also administered via injection. For clients unable to perform self-injections, this medication would not be the most appropriate option for home management of DVT.

A. Notify the physician to change the route of administration. B. Inform the client about the risks and administer the medication. C. Hold the medication and consult with the physician. D. Continue with the current medication administration schedule.

Correct Answer is C

Explanation

Choice A rationale

Changing the route of administration does not mitigate the risks associated with Category D medications during pregnancy.

Choice B rationale

Administering the medication without further consultation can pose significant risks to the fetus.

Choice C rationale

Holding the medication and consulting with the physician ensures safety by verifying the necessity and potential risks associated with the medication.

Choice D rationale

Continuing the current medication administration without consulting the physician can put both the mother and fetus at risk.
