The question is not complete, the complete question is:
The nurse asks a patient to say "ahh" while performing suctioning. What is the rationale behind this intervention?
To facilitate breathing
To elevate the bronchial passage
To assist in opening the glottis
To permit the flow of secretions into the mouth
Answer:
Making the sounds such as "ahh" helps in opening the glottis to allow entry of the catheter into the trachea. Making sounds such as "ahh" may not help in breathing. Turning the head of the patient to the side elevates the bronchial passage on the contrary side.
Continuous coughing may allow the flow of secretions into the mouth from the upper respiratory tract.
