- A. “Does this medication provide relief of migraine symptoms?â€
- B. “Has the sumatriptan helped you sleep better during the migraine?â€
- C. “Does the medication help decrease your anxiety during a migraine?â€
- D. “Has the medication prevented you from getting any more migraines?â€
Correct Answer: A
Rationale: The correct answer is A: "Does this medication provide relief of migraine symptoms?" This question directly assesses the effectiveness of sumatriptan in treating migraines, which is crucial for evaluating the medication's efficacy. Asking about symptom relief is essential in determining if the medication is working as intended.
Choices B, C, and D are incorrect because they do not directly assess the primary purpose of sumatriptan, which is to provide relief from migraine symptoms. B focuses on sleep improvement, C on anxiety reduction, and D on migraine prevention, none of which are the primary goal of sumatriptan therapy. To ensure optimal care, the focus should be on assessing the medication's effectiveness in managing the migraines.
