A patient who drinks more than 10 alcoholic beverages per day is admitted to the hospital. Twelve hours after admission, the nurse should assess the patient for abstinence syndrome which manifests as 1 2 3

Choice A rationale: While a decreased frequency of migraine headaches is a positive outcome, it does not directly indicate the immediate therapeutic effect of a sumatriptan (a serotonin receptor agonist). It may suggest a preventive effect over time.
Choice B rationale: Complete absence of migraine headaches is a positive outcome, but it is not always achievable. Immediate cessation of all headaches might not be realistic with every dose.
Choice C rationale: This is correct. Sumatriptan, a serotonin receptor agonist, is designed to terminate or relieve an ongoing migraine headache when administered during an attack. The patient reporting the termination of the migraine headache after drug administration suggests the desired therapeutic effect.
Choice D rationale: Increased nausea is not a desired therapeutic effect of sumatriptan. Sumatriptan is used to relieve the symptoms of migraines, including nausea, not exacerbate them.

Choice A rationale: Administering the medication with an empty stomach may enhance absorption but is not the best strategy for addressing "on-off" episodes.
Choice B rationale: The correct answer. High-protein foods can interfere with the absorption of levodopa, leading to "on-off" episodes.
Choice C rationale: Vitamin B6 supplementation is not typically used to address "on- off" episodes associated with levodopa/carbidopa.
Choice D rationale: Discontinuing the drug for 10 days (a "drug holiday") is not recommended and may result in a worsening of symptoms.
