A client tells the nurse that he gets dizzy and lightheaded with each use of the incentive spirometer. The nurse asks the client to demonstrate the use of the device. Which action should the nurse expect to be a contributing factor in this client's symptoms?
Correct answer
C
Rationale
Hyperventilation, caused by not resting adequately between breaths, is the most common cause of respiratory alkalosis, leading to lightheadedness and dizziness during incentive spirometer use. Inhaling or exhaling too slowly or not forming a tight seal may reduce effectiveness but does not cause these symptoms.
