A nurse is caring for a patient who requires oxygen therapy due to hypoxia. What is the goal of oxygen therapy for this patient?

To provide the highest fraction of inspired oxygen (FiO2) possible.

To use the lowest FiO2 that achieves an acceptable blood oxygen level without harmful side effects.

To maintain a constant FiO2 regardless of the patient's breathing pattern.

To deliver a fixed amount of oxygen that is independent of the patient's condition.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

The goal of oxygen therapy is not to provide the highest fraction of inspired oxygen (FiO2) possible. This approach can be harmful because excessively high FiO2 levels can lead to oxygen toxicity and other side effects, especially in patients with certain conditions like chronic obstructive pulmonary disease (COPD).

Choice B rationale:

The goal of oxygen therapy is to use the lowest FiO2 that achieves an acceptable blood oxygen level without harmful side effects. This approach is known as titrating the oxygen therapy to the patient's needs and helps prevent potential complications associated with excessive oxygen administration.

Choice C rationale:

Maintaining a constant FiO2 regardless of the patient's breathing pattern is not the goal of oxygen therapy. In some cases, patients may require varying FiO2 levels based on their respiratory status, so it is essential to adjust the oxygen delivery accordingly.

Choice D rationale:

Delivering a fixed amount of oxygen that is independent of the patient's condition is not the goal of oxygen therapy. Oxygen therapy should be individualized and tailored to the patient's specific needs to optimize its effectiveness and safety.

Correct Answer is A

Explanation

Keep the reservoir bag fully inflated at all times.

Choice A rationale:

In a partial rebreather mask, the reservoir bag should be kept fully inflated at all times to ensure the delivery of the highest possible oxygen concentration during inspiration. The bag collects oxygen during expiration, and the one-way valve prevents the exhaled gases from entering the bag. This way, the patient can inhale a mixture of oxygen from the reservoir and fresh oxygen flow.

Choice B rationale:

Breathing through the mouth and exhaling through the nose is not a necessary instruction for a patient using a partial rebreather mask. It doesn't directly impact the effectiveness of oxygen delivery.

Choice C rationale:

Adjusting the elastic strap to fit snugly around the face is not specific to ensuring effective oxygen delivery. It is a general guideline for mask fitting but doesn't directly affect oxygen administration.

Choice D rationale:

Removing the mask every 15 minutes to check the skin is not necessary and can disrupt the delivery of oxygen therapy. It's essential to maintain a consistent oxygen supply to the patient's lungs, and removing the mask frequently can compromise that. Checking the skin can be done periodically without removing the mask completely.

A. "I'm going to check your oxygen level with this device on your finger.”. B. "You need to breathe more deeply and slowly to get enough oxygen.”. C. "There is a problem with your mask and I need to fix it right away.”. D. "You are getting too much oxygen and I need to lower the flow rate.".

Correct Answer is C

Explanation

Choice A rationale:

The nurse should not immediately check the patient's oxygen level with a finger device because the priority is to address the hissing sound from the mask and the patient's pale skin color, which could indicate inadequate oxygen delivery.

Choice B rationale:

Instructing the patient to breathe more deeply and slowly won't address the issue of the hissing sound and the possible oxygen delivery problem. The nurse should address the equipment issue first.

Choice C rationale:

This is the correct choice. The nurse should inform the patient that there is a problem with the mask, and it needs to be fixed promptly to ensure adequate oxygen therapy.

Choice D rationale:

Lowering the flow rate may not be appropriate until the nurse has assessed and resolved the problem with the mask. It's essential to troubleshoot the equipment first.
