The nurse receives an order for a triptan for a patient diagnosed with a cluster headache.
What drug should be indicated for this purpose?

Choice A rationale

Discontinuing carbidopa-levodopa abruptly can lead to withdrawal symptoms and a worsening of Parkinson's symptoms. Insomnia is a possible side effect but should be managed under medical supervision.

Choice B rationale

Carbidopa-levodopa can cause orthostatic hypotension, leading to dizziness and an increased risk of falls. Patients should be advised to rise slowly from a sitting or lying position to prevent these effects.

Choice C rationale

Dark urine can be a harmless side effect of carbidopa-levodopa due to the excretion of metabolites. It is not usually a cause for concern unless accompanied by other symptoms.

Choice D rationale

High-protein foods can interfere with the absorption of carbidopa-levodopa, reducing its effectiveness. It is recommended to take the medication on an empty stomach or with low-protein foods.

Choice A rationale

Drawing up regular insulin first is recommended to avoid contamination of the vial with other types of insulin.

Choice B rationale

Incorrect, as it is standard practice to draw up regular insulin first to maintain purity and efficacy.
