Hunter is a nursing assistant measuring blood pressure. He positions the patient’s arm above the heart, palm facing down. He then places the cuff on the patient and places the arrow on the radial artery. He then uses a stethoscope and continues to finish with the blood pressure. Which best describes the error(s) he made? A. The patient’s arm should be level with the heart and palm up, and the cuff arrow should be lined up with the brachial artery.
B. The patient’s arm should be below the level of the heart.
C. The cuff should be on the patient’s carotid artery.
D. The patient’s hand should be in a fist, and a stethoscope should not be used to take blood pressure.

A35-year-old woman comes to the ed complaining of chest pressure. she has had such episodes intermittently over the last 5 years, usually when sleeping, but over the last year she has had more frequent severe symptoms that are occasionally associated with severe migraine headaches. the pain is midsternal and is described as pressure that extends as a band around her chest. the ed physician is initially dubious that the pain is cardiac in origin, because the woman has no coronary disease risk factors. an ecg, however, shows 2mm st-segment elevation and inverted t waves in leads v1 through v5 and 1mm st-segment depression in leads ii, iii, and avf. before the cardiologist arrives in the ed, the patient's ecg has returned to normal. this repeat normal ecg is obtained after the administration of aspirin, nitroglycerin, morphine, and oxygen. which of the following is most likely for these findings? - diffuse intimal thickening with focal areas of atherosclerotic narrowing - intermittent thrombus formation and lysis in the left anterior descending artery - intermittent thrombus formation and lysis in the right coronary artery - plaque rupture and thrombus formation in the left anterior descending artery - transiently increased coronary vascular tone in the right coronary artery
