Correct Answer is C
Explanation
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.
Correct Answer is B
Explanation
A. To decrease the cost of medication for the patient: While cost may be a consideration in long-term therapy, it is not the primary reason for tapering corticosteroids. The tapering process is necessary to protect the patient’s physiological balance, not driven by cost concerns.
B. To prevent the risk of acute adrenal insufficiency: Long-term prednisone use suppresses the hypothalamic-pituitary-adrenal (HPA) axis. Abrupt discontinuation can lead to adrenal insufficiency, a potentially life-threatening condition characterized by hypotension, fatigue, and electrolyte imbalances. Gradual tapering allows the adrenal glands to resume natural cortisol production.
C. To minimize the potential for drug interactions: Tapering does not reduce drug interactions. Such risks are managed through medication reconciliation and monitoring, not by adjusting steroid taper schedules.
D. To reduce the likelihood of rheumatoid arthritis flare-up: While tapering may reduce flare risk, the primary concern is adrenal suppression. Flare prevention is managed with other disease-modifying agents rather than the tapering schedule alone.
