What should the nurse do to avoid recording an erroneously low systolic blood pressure?

Inflate the cuff at least another 30 mm hg after she can't palpate the radial pulse.

The nurse should wrap an appropriate-size cuff around the clients upper arm and then place the diaphragm of the stethoscope over the brachial artery. The nurse should then rapidly inflate the cuff until she cant palpate or auscultate the pulse, then continue inflating until the pressure rises another 30 mm hg. Having the client lie down, inflating the cuff to at least 200 mg, and taking blood pressure readings in both of the client's arms arent appropriate measures.
