A nurse is preparing to obtain a client's blood pressure. Which of the following actions should the nurse plan to take?
• Record the diastolic number as the last sound heard.
• Place the lower border of the cuff slightly over the antecubital space.
• Release the air from the cuff so the pressure decreases at 5mmHg per second.
• Use a blood pressure cuff with a bladder that is 50% of the client's arm circumference.
