A nurse is obtaining a client's manual blood pressure and is having difficulty auscultating sounds. Which of the following actions should the nurse take?

A. Apply the largest cuff available: Using an inappropriately large cuff can lead to inaccurate blood pressure readings, often underestimating the true values. The cuff size should be proportional to the client’s arm circumference, not simply the largest available. B. Use the palpatory method to determine blood pressure: When Korotkoff sounds are difficult to auscultate, the nurse can use the palpatory method to estimate systolic pressure. This involves palpating the radial or brachial pulse while inflating the cuff and noting when the pulse disappears and reappears, providing a reliable alternative for measuring blood pressure. C. Place the arm above the level of the client's heart: Positioning the arm above heart level can artificially lower the measured blood pressure due to hydrostatic effects. Proper technique requires the arm to be at heart level for accurate assessment. D. Deflate the cuff quickly: Rapid deflation can cause missed Korotkoff sounds and inaccurate readings. The cuff should be deflated slowly, at a rate of 2–3 mm Hg per second, to ensure correct auscultation of both systolic and diastolic pressures.
