Which instruction should the nurse give a patient using an incentive spirometer after abdominal surgery?
Correct answer: A. Inhale slowly through the mouthpiece and hold the breath briefly
- A. Inhale slowly through the mouthpiece and hold the breath briefly
- B. Exhale forcefully into the mouthpiece and cough immediately
- C. Breathe rapidly through the mouthpiece until dizzy
- D. Use the device only when shortness of breath begins
Explanation
The patient should sit upright, seal the lips around the mouthpiece, inhale slowly and deeply, then briefly hold the breath. This helps expand alveoli and prevent atelectasis; rapid breathing and forceful exhalation do not achieve the intended effect.
