The patient inhales deeply through pursed lips and exhales quickly through the nose.

Answer and Explanation

The Correct Answer is C

A. Inhaling and exhaling quickly through pursed lips does not achieve the intended purpose of pursed-lip breathing. This technique is designed to promote slower, controlled breathing to prevent airway collapse and improve oxygen exchange.

B. Exhaling quickly through pursed lips negates the benefits of pursed-lip breathing. The purpose of this technique is to prolong exhalation, reducing air trapping and improving ventilation.

C. Inhaling deeply through the nose and exhaling slowly through pursed lips is the correct technique for pursed-lip breathing. This method helps maintain open airways, reduces dyspnea, and promotes relaxation.

D. Inhaling deeply through pursed lips and exhaling quickly through the nose is not consistent with proper pursed-lip breathing. The inhalation should be through the nose, and exhalation should be slow and controlled through pursed lips.
