What is the student's best response?

Vasodilation of peripheral blood vessels.

Depresses pain response in the central nervous system.

Vasoconstrictive on cranial blood vessels.

Binds to acetylcholine receptors to prevent nerve transmission.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Sumatriptan does not cause vasodilation of peripheral blood vessels. Instead, it has vasoconstrictive properties.

Choice B rationale

Sumatriptan does not depress pain response in the central nervous system. Its primary action is on the cranial blood vessels.

Choice C rationale

Sumatriptan is a selective serotonin receptor agonist that causes vasoconstriction of cranial blood vessels, relieving migraine headaches.

Choice D rationale

Sumatriptan does not bind to acetylcholine receptors or prevent nerve transmission. It specifically targets serotonin receptors in cranial blood vessels.

Choice A rationale

Teaching the patient how to cope with therapy helps ensure the best outcomes by promoting adherence and understanding of the treatment regimen.

Choice B rationale

Nurses should not alter drug regimens; this is the responsibility of the prescribing healthcare provider.

Choice C rationale

Evaluating the effectiveness of therapy is a critical nursing responsibility to ensure that the treatment is achieving the desired outcomes.

While providing therapy is part of nursing care, it should not include altering the medication regimen.

Choice E rationale

A. As needed at the first sign of nausea. B. When seated just prior to takeoff. C. At 0830 just prior to boarding the flight. D. At 0700 before leaving for the airport.

Correct Answer is D

Explanation

Choice A rationale

Taking medication at the first sign of nausea may be too late to prevent motion sickness as it takes time for the medication to be absorbed and take effect.

Choice B rationale

Taking medication just prior to takeoff might not give the drug enough time to be absorbed and start working effectively.

Choice C rationale

Taking medication just prior to boarding the flight may not provide sufficient time for the drug to reach its peak effectiveness.

Choice D rationale

Taking the medication at 0700 before leaving for the airport allows enough time for the drug to be absorbed and reach its peak effect, which is essential for preventing motion sickness during the flight.
