(Select all that apply): A client with a tracheostomy is being weaned from mechanical ventilation. Which of the following oxygen delivery devices can be used for this client?
Venturi mask.
Tracheostomy collar.
T-piece.
Aerosol mask.
Mechanical ventilator.
Correct Answer : B,C,D
Choice A rationale:
Venturi masks are not typically used with tracheostomy patients, as they are more suitable for patients with intact upper airways.
Choice B rationale:
Tracheostomy collars are specifically designed for patients with tracheostomies. They provide oxygen directly to the tracheostomy tube, making them appropriate for weaning tracheostomized patients from mechanical ventilation.
Choice C rationale:
T-piece adapters are commonly used for patients with tracheostomies to deliver oxygen. They are simple devices that deliver oxygen directly to the tracheostomy tube.
Choice D rationale:
Aerosol masks are not specifically designed for tracheostomy patients and may not provide adequate oxygen delivery for them.
Choice E rationale:
Mechanical ventilators are not an oxygen delivery device; instead, they are used to provide mechanical ventilation support to the patient and can incorporate various oxygen delivery systems.

Correct Answer is B
Explanation
Choice A rationale:
The patient's PaO2 is 65 mmHg and SaO2 is 88%. PaO2 values below 80 mmHg and SaO2 below 90% are considered below normal ranges. Therefore, the patient's oxygen levels are not within the normal range for the condition.
Choice B rationale:
This is the correct choice. The patient's PaO2 and SaO2 levels indicate that they are not receiving enough oxygen, and additional oxygen therapy is needed.
Choice C rationale:
The patient's oxygen levels are low, not high. Providing less oxygen would worsen the situation.
Choice D rationale:
The patient's oxygen levels are affected by oxygen therapy, as they indicate that the current therapy is insufficient. Additional interventions are needed to improve oxygenation.
Correct Answer is D
Explanation
Choice A rationale:
Nasal cannula delivers low to moderate concentrations of oxygen and may not be effective for a client with thick secretions, dry mucous membranes, or upper airway edema. Additionally, the nasal cannula may not provide sufficient humidification to alleviate these conditions.
Choice B rationale:
The simple face mask is not ideal for a client with thick secretions, dry mucous membranes, or upper airway edema as it may not provide enough humidification and could be uncomfortable for the patient.
Choice C rationale:
A partial rebreather mask also may not be the most appropriate choice for this client as it has a reservoir bag that may not adequately humidify the oxygen, leading to discomfort and potential worsening of dry mucous membranes.
Choice D rationale:
The aerosol mask is the most appropriate choice because it delivers humidified oxygen in the form of small aerosol particles, which can help alleviate thick secretions, moisturize dry mucous membranes, and reduce upper airway edema. This mask is beneficial for patients who require higher humidity levels to maintain airway patency and comfort.
