Answer: c. Place the bell of the stethoscope over the brachial artery.
Explanation: To obtain an accurate blood pressure reading, the nurse should place the bell of the stethoscope over the brachial artery, which is located in the antecubital fossa.
a. Inflating the cuff to 20 mmHg above the estimated systolic pressure may be appropriate for initial inflation, but the cuff should be inflated further until the radial pulse disappears, and then slowly deflated to obtain accurate readings.
b. Deflating the cuff at a rate of 2-3 mmHg per second is recommended to obtain accurate blood pressure readings.
d. Palpating the radial artery while auscultating for Korotkoff sounds is not necessary for accurate blood pressure measurement and may interfere with accurate assessment.
