Answer to Question 1

Ans: B
Ergotamine relieves migraine headaches by constricting, not dilating, cerebral arterial vessels. The drug's ability to prevent norepinephrine reuptake may add to this effect. The net result is decreased pulsatile blood flow through the cerebral vessels and symptom relief. Ergotamine doesn't decrease peripheral vascular resistance or stimulation of baroreceptors.

Answer to Question 2

Ans: D
Nurses in ambulatory care centers and clinics provide technical services (e.g., administering medications), determine the priority of care needs, and provide teaching about all aspects of care. The urgent care center is a special type of ambulatory care center that provides walk-in care for illnesses and minor trauma. Crisis management or intervention is typical of mental health centers and not of ambulatory care settings.
