Steve, age 42, has never been hypertensive but appears today in the office with a blood pressure of 162/100 mm Hg. He also complains of "attacks" of headache, perspiration, and palpitations, with frequent bouts of nausea, pain, weakness, dyspnea, and visual disturbances. He has lost 10 lb over the past 2 months and seems very anxious today. Your next action would be to:a. Obtain a 24 hour urine test for catecholamines b. recheck his blood pressure in 1 week.
