Answer to Question 1
A
Although it is true that patient report correlates poorly with actual allergy, there is a risk of life-threatening anaphylaxis with a true penicillin allergy. The NP should order a penicillin skin test to verify allergy. If the skin test is positive, the patient should avoid B-lactam antimicrobials. Penicillin desensitization can be used for penicillin-allergic patients who need penicillins.
Answer to Question 2
B
If the patient is able to take medication at the earliest onset of migraine, ergots are usually effective. Triptans are more effective when patients have difficulty catching the headache in time. Sumatriptan begins to work in 15 minutes and so would be indicated for this patient. Frovatriptan has a longer half-life. Cyproheptadine is not a first-line migraine treatment.
