You are dispatched to a residence for a 44-year-old woman with a severe headache. You arrive to find the patient lying on her sofa with a wet washcloth on her forehead. She tells you that she has a history of migraine headaches and that this is one of her "typical" headaches. She also complains of nausea and photophobia. Her blood pressure is 170/94 mm Hg, pulse rate is 120 beats/min and regular, and respirations are 22 breaths/min with adequate depth. The MOST appropriate treatment for this patient includes:

A) carefully assessing her pupils, administering oxygen, starting an IV and giving her morphine, and transporting.
B) placing her in a Fowler position, administering oxygen, and transporting her to the hospital for definitive care.
C) oxygen as tolerated, starting an IV line and administering ondansetron, and transporting without lights or siren.
D) administering high-flow oxygen, establishing vascular access, and administering nitroglycerin to lower her blood pressure.

Ans: C) oxygen as tolerated, starting an IV line and administering ondansetron, and transporting without lights or siren.
