Problem: An older adult client reports dizziness upon standing. The nurse obtains blood pressure and pulse rate while the client is seated, then while standing. The nurse observes a decrease of 20 mm Hg in the blood pressure and an increase of 20 beats/min in the pulse rate. What education by the nurse is important to decrease the incidence of orthostatic hypotension in this client? Select all that apply. Avoid sitting or standing for prolonged periods, especially after a meal. Eat small frequent meals throughout the day. Rise slowly when standing from sitting or lying. Increase activity level after eating a meal. Drink at least 6 to 8 glasses of fluid daily if permitted.
