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.
The Correct Answer is C
Choice A rationale

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

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

Choice A rationale
Asking the patient what time of day the medication is taken can help identify if taking it at a different time might alleviate sleep disturbances. SSRIs like sertraline can cause insomnia if taken later in the day.
Choice B rationale
Recommending a weekly dosage is inappropriate and could potentially disrupt the therapeutic effect. SSRIs should be taken daily, as prescribed.
Choice C rationale
Counseling the patient to take the medication at bedtime could worsen sleep disturbances, as sertraline may cause insomnia in some individuals. Timing should be adjusted based on patient response.
Choice D rationale
Suggesting a lower dose without consulting the provider may not address the issue effectively and could reduce the efficacy of the medication. Dosage adjustments should be made based on clinical assessment and provider recommendation.
