A. two deep breaths, then inhale deeply again and force out the air quickly. B. one deep breath and quickly exhale C. one breath, hold it for 3 seconds, then forcefully exhale three times with mouth open D. two breaths and force the air out quickly

Correct Answer is A

Explanation

A. Two deep breaths, then inhale deeply again and force out the air quickly: This technique helps clear mucus by mobilizing it toward the larger airways for expulsion.
B. One deep breath and quickly exhale: This method is less effective in mobilizing secretions compared to multiple preparatory breaths.
C. One breath, hold it for 3 seconds, then forcefully exhale three times with mouth open: Holding the breath promotes mucus loosening, and repeated exhalations help clear secretions. While this technique can be correct in some protocols, it is less common for "forceful" cough instructions and may not be the preferred method.
D. Two breaths and force the air out quickly: Lacks the preparatory deep breath necessary for effective secretion clearance.
