What is the classic sign of diffusion impairment in hypoxemic respiratory failure?
Increased sleepiness
Hypoxemia is worse with activity, better with rest
Chest pain that occurs with activity and is better at rest
Asymmetrical chest movement
The Correct Answer is B
A. Increased sleepiness: While hypoxemia can eventually lead to fatigue or altered mental status, sleepiness is not the classic early sign of diffusion impairment in hypoxemic respiratory failure.
B. Hypoxemia is worse with activity, better with rest: Diffusion impairment limits oxygen transfer across the alveolar-capillary membrane. During activity, oxygen demand increases, and the impaired diffusion results in more pronounced hypoxemia. Rest decreases oxygen demand, allowing partial compensation.
C. Chest pain that occurs with activity and is better at rest: This is more characteristic of cardiac ischemia rather than diffusion impairment in the lungs.
D. Asymmetrical chest movement: Unequal chest movement suggests localized lung pathology, pneumothorax, or obstruction, not a global diffusion problem in hypoxemic respiratory failure.

Correct Answer is ["A","C"]
Explanation
A. Patient should be able to independently maintain an airway: Maintaining a patent airway is a primary goal in acute respiratory failure. This ensures adequate oxygenation and ventilation, reducing the risk of hypoxemia and hypercapnia.
B. Patient should be able to walk around the nurse's station 5 times every hour: Ambulation may be part of general recovery, but it is not a specific goal for managing acute respiratory failure. Focus should remain on airway, oxygenation, and ventilation.
C. Patient should be able to effectively cough and clear secretions on own: Effective secretion clearance prevents airway obstruction and infection, supporting oxygenation and reducing the risk of further respiratory compromise.
D. Patient should be fever free for 24 hours: While controlling infection may be important, being fever-free is not a direct goal of managing acute respiratory failure. The primary focus is on airway and gas exchange.
Correct Answer is C
Explanation
A. Slight movement of the ET tube during repositioning: Minor movement of the ET tube can occur when repositioning the patient and is usually expected. It should be monitored, but it does not typically require immediate intervention if the tube remains secure.
B. Occasional bubbling in the oral secretions: Small amounts of bubbling in secretions can be normal and may indicate mild saliva accumulation or humidified air from the ventilator. This finding is not immediately dangerous but should be suctioned as needed.
C. Asymmetrical chest rise during mechanical ventilation: Unequal chest expansion suggests possible tube displacement, obstruction, or a pneumothorax. This is a serious finding that can compromise oxygenation and ventilation, requiring immediate assessment and intervention to ensure airway safety.
D. Minor redness around the mouth from the ET tube securement: Redness at the securing site is a common skin irritation due to tape or straps. It is important to monitor and provide skin care, but it does not represent an acute airway emergency.
