Which of the following oxygen delivery devices provides the most precise and consistent fraction of inspired oxygen (FiO2) regardless of the patient's breathing pattern?

Nasal cannula.

Simple face mask.

Venturi mask.

Non-rebreather mask.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Nasal cannula delivers oxygen through two small prongs placed in the patient's nostrils. While it is a commonly used and well-tolerated device, the FiO2 delivered can vary significantly depending on the patient's breathing pattern and respiratory rate. Thus, it does not provide the most precise and consistent FiO2.

Choice B rationale:

Simple face masks cover the nose and mouth and can provide higher FiO2 levels compared to nasal cannulas. However, the FiO2 delivered still depends on the patient's breathing pattern and the mask's fit, making it less precise and consistent than other options.

Choice C rationale:

Venturi masks are designed to deliver a specific and accurate FiO2, regardless of the patient's breathing pattern. These masks have adjustable ports to control the mix of air and oxygen, providing precise oxygen concentrations.

Choice D rationale:

Non-rebreather masks have one-way valves and a reservoir bag to deliver higher concentrations of oxygen. Although they can provide high FiO2 levels, the delivered concentration can vary based on the patient's breathing pattern and the mask's fit.

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.

A. "You should refill the tank when it feels light and empty.”. B. "You should refill the tank when the pressure gauge reads below 500 psi.”. C. "You should refill the tank when you hear a hissing sound from the valve.”. D. "You should refill the tank when an alarm sounds from the regulator.".

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.
