Which of the following describes why monitoring proper tracheostomy cuff pressure between 15 to 25 cm H2O is important?

prevents overinflation of the cuff which can lead to tracheoesophageal fistula

Allows the client to speak without aspirating

Allows for passage of oxygen around the cuff

Allows for more effective suctioning

Answer and Explanation

The Correct Answer is A

A. Prevents overinflation of the cuff which can lead to tracheoesophageal fistula: Maintaining cuff pressure between 15 to 25 cm H₂O prevents excessive pressure on the tracheal mucosa, which can cause ischemia, necrosis, and complications such as tracheoesophageal fistula. Proper cuff inflation balances the need to seal the airway while minimizing tissue injury, ensuring safe long-term tracheostomy care.

B. Allows the client to speak without aspirating: While cuff deflation or use of a speaking valve enables phonation, cuff pressure maintenance is primarily for airway protection rather than facilitating speech. Speaking is a secondary concern and is managed separately from strict cuff pressure monitoring.

C. Allows for passage of oxygen around the cuff: The cuff is designed to create a seal and prevent air leaks; maintaining appropriate pressure does not intentionally allow oxygen to pass around it. Allowing oxygen to leak around the cuff would compromise ventilation and increase aspiration risk.

D. Allows for more effective suctioning: Suctioning is performed either through an open or closed system and is independent of cuff pressure. The cuff’s main role is to protect the lower airway and prevent aspiration, not to enhance suctioning effectiveness.

Correct Answer is D

Explanation

A. Hold the insertion site open with a Kelly clamp: Inserting or holding instruments at the chest tube site is unsafe and can worsen injury or introduce infection. Manipulating the site with a clamp is not appropriate and does not address the immediate risk of air entering the pleural space.

B. Clamp the chest tube: Clamping a chest tube after it has been accidentally dislodged can trap air or fluid in the pleural space, increasing the risk of tension pneumothorax. Clamping is not recommended in this emergency situation unless instructed by a provider for specific circumstances.

C. Call the rapid response team and continue on to the radiology department: While notifying the rapid response team is important, leaving the client without addressing the open chest wound could rapidly lead to respiratory compromise. Immediate action to protect the pleural space takes priority over calling for help or continuing to radiology.

D. Cover the insertion site with the cleanest material available: The priority is to create an occlusive barrier to prevent air from entering the pleural space, which could cause a tension pneumothorax. Using the cleanest material immediately available stabilizes the situation while additional help is summoned, protecting the client from further respiratory compromise.

A. Increase the rate and/or tidal volume B. Increase the PEEP C. Sedate and paralyze the client D. Increase the FiO2 and/or PEEP

Correct Answer is A

Explanation

A. Increase the rate and/or tidal volume: Respiratory acidosis occurs when CO₂ retention results from hypoventilation. Adjusting the ventilator to increase the respiratory rate or tidal volume enhances alveolar ventilation, helping to remove CO₂ and correct the acidosis. This intervention directly targets the underlying cause of the abnormal ABG.

B. Increase the PEEP: Positive end-expiratory pressure helps keep alveoli open and improve oxygenation but does not directly increase CO₂ elimination. While beneficial for hypoxemia, adjusting PEEP alone will not correct respiratory acidosis caused by hypoventilation.

C. Sedate and paralyze the client: Sedation and paralysis may be used to facilitate ventilator synchrony in specific situations, but they do not directly correct CO₂ retention. These interventions are not the first-line approach for managing respiratory acidosis and could worsen hypoventilation if not carefully managed.

D. Increase the FiO2 and/or PEEP: Increasing FiO₂ and PEEP improves oxygenation but does not enhance CO₂ removal. Respiratory acidosis requires interventions that increase alveolar ventilation rather than just oxygen delivery.
