A nurse is providing care for a patient with a tracheostomy tube. What type of tracheostomy tube would be most suitable for a patient who requires mechanical ventilation or has a high risk of aspiration?
Cuffed.
Uncuffed.
Fenestrated.
Double-lumen.
Metal.
The Correct Answer is A
Choice A rationale:
A cuffed tracheostomy tube is most suitable for a patient who requires mechanical ventilation or has a high risk of aspiration. The cuff is inflated to create a seal between the trachea and the tube, preventing aspiration of oral secretions or gastric contents into the airway. This is crucial for patients on mechanical ventilation to ensure effective ventilation and prevent complications like ventilator-associated pneumonia.
Choice B rationale:
Uncuffed tracheostomy tubes do not have an inflatable cuff, making them unsuitable for patients who require mechanical ventilation or have a high risk of aspiration. They are more appropriate for patients who can protect their own airway and have minimal risk of aspiration.
Choice C rationale:
Fenestrated tracheostomy tubes have an opening or fenestration on the tube that allows airflow through the upper airway, bypassing the tracheostomy tube. These tubes are used for patients who are weaning off mechanical ventilation and require speech therapy. They are not the most suitable choice for patients who need mechanical ventilation or have a high aspiration risk.
Choice D rationale:
Double-lumen tracheostomy tubes have two separate tubes, which can be used for independent lung ventilation in certain situations. They are not specifically designed for patients requiring mechanical ventilation or with a high risk of aspiration.
Choice E rationale:
Metal tracheostomy tubes are not commonly used for patients requiring mechanical ventilation or with a high risk of aspiration. Metal tubes may be used in certain cases, but they are not the most suitable choice for this patient population.

Correct Answer is ["B","C","D","E"]
Explanation
Choice A rationale:
Applying continuous suction while inserting the catheter can cause trauma to the tracheal mucosa and increase the risk of bleeding and infection.
Choice B rationale:
Rinsing the catheter with sterile saline between each suctioning attempt helps maintain aseptic technique, preventing the introduction of microorganisms into the airway.
Choice C rationale:
Limiting suctioning attempts to three per session reduces the risk of hypoxia and mucosal damage, ensuring adequate oxygenation and preventing complications.
Choice D rationale:
Withdrawing the catheter gently while applying suction prevents damage to the tracheal walls and minimizes the risk of bleeding.
Choice E rationale:
Hyperoxygenating the patient before and after suctioning helps prevent hypoxemia during the procedure, reducing the risk of complications and ensuring adequate oxygenation.
Correct Answer is B
Explanation
Choice A rationale:
While notifying the healthcare provider is essential, the priority action in this situation is to stop the bleeding to prevent further complications.
Choice B rationale:
Applying direct pressure to the tracheostomy stoma is the first action the nurse should take to control the bleeding and stabilize the patient.
Choice C rationale:
Administering fluids and blood products may be necessary later, but it is not the first action to take when dealing with active bleeding.
Choice D rationale:
Ensuring proper positioning and alignment of the tracheostomy tube is important, but it is not the priority in this critical situation.
