What is the most appropriate oxygen delivery device for a client with thick secretions, dry mucous membranes, or upper airway edema?
Nasal cannula.
Simple face mask.
Partial rebreather mask.
Aerosol mask.
The Correct Answer is D
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.

Correct Answer is D
Explanation
Choice A rationale:
Monitoring the patient's respiratory rate, depth, rhythm, and effort is crucial for assessing the effectiveness of oxygen therapy and ensuring proper oxygenation through the tracheostomy collar.
Choice B rationale:
Educating the patient on how to use and care for the tracheostomy collar is essential to ensure the patient's safety and compliance with the therapy.
Choice C rationale:
Implementing safety measures to prevent fire hazards from the oxygen source is crucial, especially when oxygen is delivered via tracheostomy collar, which may have increased oxygen flow rates.
Choice D rationale:
This is the correct choice. All the provided interventions (monitoring respiratory parameters, patient education, and safety measures) are essential components of the plan of care for a patient with a tracheostomy who requires oxygen therapy.
Correct Answer is B
Explanation
Choice A rationale:
Refilling the oxygen tank based on the client's perception of it feeling light and empty is not a reliable method, as it may lead to running out of oxygen unexpectedly.
Choice B rationale:
The nurse should instruct the client to refill the oxygen tank when the pressure gauge reads below 500 psi. This is a standardized method to ensure the client does not run out of oxygen, as the pressure gauge provides an accurate measure of the remaining oxygen in the tank.
Choice C rationale:
Refilling the tank when a hissing sound is heard from the valve is not a valid method for determining the need for a refill and may result in running out of oxygen.
Choice D rationale:
Waiting for an alarm sound from the regulator to refill the tank is not recommended, as the tank could run out of oxygen before the alarm activates.
