A nurse is preparing to administer a triptan medication to a patient experiencing an acute migraine. Which of the following statements about triptan administration is correct?

A. Triptans should be administered only after other pain medications have been tried: Triptans are first-line agents for moderate to severe migraines and do not require prior use of other analgesics. Delaying their use can reduce effectiveness and prolong the migraine episode. B. Triptans should be administered at the onset of aura symptoms: Triptans are not recommended during the aura phase, especially for patients with migraines that involve motor or sensory auras, due to concerns about vasoconstrictive effects before pain begins. They are intended for use when headache pain starts. C. Triptans are most effective when taken early in the migraine attack, at the onset of pain: Triptans work by stimulating serotonin receptors, causing cranial vasoconstriction and reducing neurogenic inflammation. They are most effective when taken as soon as the headache phase begins, not during aura or late in the attack. D. Triptans can be safely administered every hour until pain relief is achieved: Triptans have strict dosing intervals due to their vasoconstrictive properties, and exceeding recommended doses can lead to cardiovascular complications. They should not be taken more frequently than prescribed.
