Ну теперь, когда все убедились в своем высоком официальном и неофициальном IQ можно продолжить:
A 21-year-old man comes to the clinic for a follow-up visit. He has been found to be hypertensive with bilateral arm blood pressures in the 140-160/100-110 mm Hg range on several visits. The patient has no past medical history and has no complaints. Review of systems is significant for occasional “band-like headaches". Physical examination is normal including a normal retinal examination. Urinalysis is normal. An electrocardiogram demonstrates normal sinus rhythms at a rate of 75/min, with mild left ventricular hypertrophy. His blood pressure is now 150/100 mm Hg after treatment with maximal doses of atenolol, hydrochlorothiazide, and captopril. The next step in the evaluation of this patient's hypertension is to
A. order a duplex ultrasound of the renal arteries
B. order an echocardiogram
C. prescribe triamterene
D. repeat the electrocardiogram
E. repeat the ophthalmoscopic examination
