A nurse is evaluating the effectiveness of oxygen therapy for a patient who has COPD. The nurse notes that the patient's PaO2 is 65 mmHg and SaO2 is 88%. What should the nurse say to the patient?

"Your oxygen levels are within the normal range for your condition.”.

"Your oxygen levels are too low and you need more oxygen.”.

"Your oxygen levels are too high and you need less oxygen.”.

"Your oxygen levels are not affected by your oxygen therapy.".

Answer and Explanation

The Correct Answer is B

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 A

Explanation

The correct answer is choice a. PaO2 80 mmHg.

Choice A rationale:

PaO2 (partial pressure of oxygen in arterial blood) of 80 mmHg indicates that the oxygen therapy has been effective. Normal PaO2 levels range from 75 to 100 mmHg, so a value of 80 mmHg suggests adequate oxygenation.

Choice B rationale:

SaO2 (arterial oxygen saturation) of 88% is below the normal range (typically 95-100%) and indicates hypoxemia, suggesting that the oxygen therapy has not been fully effective.

Choice C rationale:

A respiratory rate (RR) of 32 breaths per minute is significantly higher than the normal range (12-20 breaths per minute) and indicates respiratory distress, suggesting that the oxygen therapy has not been effective.

Choice D rationale:

Blood pressure (BP) of 160/90 mmHg is elevated and indicates hypertension, which is not a direct measure of the effectiveness of oxygen therapy. This finding does not provide information about the patient’s oxygenation status.

A. To provide the highest fraction of inspired oxygen (FiO2) possible. B. To use the lowest FiO2 that achieves an acceptable blood oxygen level without harmful side effects. C. To maintain a constant FiO2 regardless of the patient's breathing pattern. D. To deliver a fixed amount of oxygen that is independent of the patient's condition.

Correct Answer is B

Explanation

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.
