Where does the brach-ial artery lie in relation to the biceps tendon in the antecubital fossa?
The brachial artery lies under, or just medial to, the biceps tendon. When taking the blood pressure, should you aus-cultate with the dia-phragm or with the bell? The Korotkoff sounds are low-pitched, so they are better heard with the bell. In practice, everyone uses the diaphragm. Does the loudness of the Korotkoff sounds vary with the distance of the stethoscope from the lower edge of the cuff? Yes. The closer the stethoscope is to the cuff, the louder the sounds. If you have trouble hearing the sounds in a patient in shock, try slipping the edge of the diaphragm under the edge of the cuff. Does the position of the patient’s arm affect the blood pressure readings? Yes. If the arm is held above heart level, the readings may be falsely low. If the arm is held below heart level (as often happens when the patient is sitting on the examining table), the pressure may be falsely high. If you measure the sitting blood pressure, be sure to hold the patient’s arm at heart level. What important
