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.

A. A nonrebreather mask should fit snugly over a client's face. B. The reservoir bag on a nonrebreather mask should collapse with exhalation. C. A nonrebreather mask dries a client's mucous membranes. D. Use a non rebreather mask to deliver low-flow oxygen.

Correct Answer is A

Explanation

A) A nonrebreather mask should fit snugly over a client's face. A proper fit ensures effective oxygen delivery and prevents room air from entering the mask.
B) The reservoir bag on a nonrebreather mask should collapse with exhalation. The reservoir bag should not completely collapse. If it does, the oxygen flow may be inadequate.
C) A nonrebreather mask dries a client's mucous membranes. While high-flow oxygen delivery systems can dry mucous membranes, this is not specific to non rebreather masks.
D) Use a non rebreather mask to deliver low-flow oxygen. Non rebreather masks are designed to deliver high concentrations of oxygen (typically 60% to 100%).
