Review Question - QID 108508

A 76-year-old woman presents to her primary care physician with an intense, throbbing, right-sided headache. She has a history of migraine headaches and tried her usual medications this afternoon with no alleviation of symptoms. She states that this headache feels different because she also has pain in her jaw that is worse with chewing. The pain came on gradually and is getting worse. In addition, over the past few months, she has had some difficulty getting up out of chairs and raising both her arms over her head to put on her clothes. She has had no recent falls or injuries. On exam, the patient's temperature is 98.3°F (36.8°C), blood pressure is 115/70 mmHg, pulse is 93/min, and respirations are 15/min. The patient has tenderness over her right temple. She has no focal neurological deficits, and no abnormalities on fundoscopic exam. Her physical exam is otherwise within normal limits.

Given the patient's most likely diagnosis, which of the following methods of treatment should be used in order to prevent any further complications?
