The nurse clarifies that the cough mechanism is stimulated when:

more than 250 mL of air moves in and out of the lungs with each breath

foreign substances are propelled by the cilia toward the respiratory tract

dehumidified air enters the upper airway passages

the blood transports carbon dioxide to the lungs

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is ["A","B","D"]

Explanation

A. Aspirated vomit: Can obstruct the airway or cause aspiration pneumonia, reducing oxygenation.
B. Pulmonary fibrosis: Scarring of lung tissue impairs gas exchange, leading to hypoxia.
C. Hiccoughs: Not associated with hypoxia; they are an involuntary diaphragmatic spasm.
D. High altitude: Decreased atmospheric oxygen levels can result in hypoxia.

A. take a good nap B. turn, cough and deep breathe C. submit to a back rub D. take some pain medication

Correct Answer is C

Explanation

A. Take a good nap: While rest is important, shallow breathing and irritability may indicate inadequate ventilation, which won't improve solely with sleep.
B. Turn, cough, and deep breathe: This helps open the airways, promotes alveolar expansion, and clears secretions, which may improve oxygenation and reduce restlessness.
C. Submit to a back rub: Although comforting, it does not directly address shallow breathing or improve oxygenation.
D. Take some pain medication: Pain control can be essential, but this action is premature without assessing whether pain is the cause of shallow breathing.
