Which instruction is correct when teaching a patient to perform deep-breathing exercises after surgery?
Correct answer: B. Inhale slowly through the nose and exhale slowly
- A. Take rapid shallow breaths through the mouth
- B. Inhale slowly through the nose and exhale slowly
- C. Hold each breath only while coughing
- D. Breathe normally without expanding the chest
Explanation
Slow deep inhalation expands the alveoli and helps prevent atelectasis, while slow exhalation promotes controlled ventilation. Rapid shallow breathing does not adequately inflate dependent lung areas.
