Which does the nurse implement to obtain an accurate measurement of a client's blood pressure on an upper extremity?

2. Limits the cuff deflation rate to 10 mm Hg per second
3. Records second Korotkoff sound as the systolic pressure
4. Applies stethoscope's diaphragm over brachial artery lightly

1. For accurate results, a properly sized blood pressure cuff is at least 40% wider than the circumference of the client's arm on which the blood pressure is measured.
2. Deflating the cuff at 10 mm Hg is excessively fast.
3. The systolic blood pressure is the first Korotkoff sound.
4. The diaphragm is placed firmly over the brachial artery to eliminate environmental sound from interfering with blood pressure auscultation.
