Correct Answer is D

Explanation

A. Apply suction while advancing the catheter into the airway: This increases the risk of tissue trauma and should be avoided. Suction should only be applied during withdrawal.
B. Insert the non-lubricated catheter into the nasal passage: Lubrication is necessary to prevent nasal tissue trauma and facilitate smoother insertion.
C. Suction the nasotracheal passage after suctioning the mouth: Suctioning the mouth first introduces contamination into the sterile airway, increasing the risk of infection.
D. Hold the catheter with the dominant hand after donning sterile gloves: This technique maintains sterility and prevents contamination of the catheter during the procedure.

A. more than 250 mL of air moves in and out of the lungs with each breath B. foreign substances are propelled by the cilia toward the respiratory tract C. dehumidified air enters the upper airway passages D. the blood transports carbon dioxide to the lungs

Correct Answer is B

Explanation

A. More than 250 mL of air moves in and out of the lungs with each breath: This describes tidal volume but does not directly stimulate the cough mechanism.
B. Foreign substances are propelled by the cilia toward the respiratory tract: Irritation by foreign particles stimulates the cough reflex to clear the airways.
C. Dehumidified air enters the upper airway passages: Dry air can cause airway irritation but does not consistently trigger a cough reflex.
D. The blood transports carbon dioxide to the lungs: This describes gas exchange, which does not directly relate to triggering the cough mechanism.
