Question 1:

A client with chronic obstructive pulmonary disease (COPD) presents with severe dyspnea and hypoxemia. What is the appropriate indication for initiating oxygen therapy in this client?

A. Maintaining oxygen saturation above 95% B. Correcting underlying lung pathology C. Relieving shortness of breath D. Preventing complications of hypoxia

Answer and Explanation

Choice A:

Maintaining oxygen saturation above 95% is not the primary indication for oxygen therapy in clients with COPD. Target oxygen saturation levels may be lower due to the risk of suppressing the respiratory drive.

Choice B:

Correcting underlying lung pathology may require other interventions but does not solely indicate oxygen therapy.

Choice C:

Relieving shortness of breath may be a beneficial outcome of oxygen therapy, but it is not the primary indication in this case.

Choice D:

Preventing complications of hypoxia Explanation: Oxygen therapy is indicated in clients with COPD to prevent complications of hypoxia, such as tissue damage and respiratory failure.

Question 2:

A client with pneumonia exhibits signs of respiratory distress and decreased oxygen saturation. What is the primary indication for initiating oxygen therapy in this client?

A. Promoting lung expansion B. Enhancing antimicrobial therapy C. Improving oxygen delivery to tissues D. Reducing the risk of bacterial resistance

Answer and Explanation

Choice A:

Promoting lung expansion is a goal of oxygen therapy but is not the primary indication in this case.

Choice B:

Enhancing antimicrobial therapy is essential for treating pneumonia but is not directly related to the need for oxygen therapy.

Choice C:

Improving oxygen delivery to tissues Explanation: In a client with pneumonia, the primary indication for oxygen therapy is to improve oxygen delivery to tissues and alleviate hypoxia.

Choice D:

Reducing the risk of bacterial resistance is not an indication for oxygen therapy but rather a consideration for appropriate antibiotic use.

Question 3:

A client with congestive heart failure (CHF) experiences worsening dyspnea and peripheral edema. What is the primary indication for initiating oxygen therapy in this client?

A. Reducing the workload of the heart B. Decreasing peripheral edema C. Preventing fluid overload D. Improving myocardial oxygenation

Answer and Explanation

Choice A:

Reducing the workload of the heart is a potential benefit of oxygen therapy but is not the primary indication in this case.

Choice B:

Decreasing peripheral edema is not a direct indication for oxygen therapy.

Choice C:

Preventing fluid overload is important in managing CHF but does not directly relate to the need for oxygen therapy.

Choice D:

Improving myocardial oxygenation Explanation: In clients with CHF, the primary indication for oxygen therapy is to improve myocardial oxygenation and relieve symptoms of myocardial ischemia.

Question 4:

A client with anemia presents with fatigue and decreased exercise tolerance. What is the primary indication for initiating oxygen therapy in this client?

A. Increasing oxygen-carrying capacity B. Reducing iron deficiency C. Promoting tissue healing D. Enhancing erythropoiesis

Answer and Explanation

Choice A:

In a client with anemia, the primary indication for oxygen therapy is to increase the oxygen-carrying capacity of the blood and improve tissue oxygenation.

Choice B:

Reducing iron deficiency is a necessary intervention for managing anemia but is not the primary indication for oxygen therapy.

Choice C:

Promoting tissue healing may be a general benefit of adequate oxygenation, but it is not the primary indication in this case.

Choice D:

Enhancing erythropoiesis is important for treating anemia but does not directly relate to the need for oxygen therapy

Question 5:

A client with a traumatic brain injury (TBI) develops altered mental status and decreased oxygen saturation. What is the primary indication for initiating oxygen therapy in this client?

A. Preventing cerebral edema B. Improving neurological function C. Stabilizing blood pressure D. Ensuring adequate oxygen supply to the brain

Answer and Explanation

Choice A:

Preventing cerebral edema is an important goal in managing a TBI, but it is not the primary indication for oxygen therapy.

Choice B:

Improving neurological function may be an eventual outcome of adequate oxygenation, but it is not the primary indication in this case.

Choice C:

Stabilizing blood pressure is crucial in TBI management, but it does not directly relate to the need for oxygen therapy.

Choice D:

In a client with a traumatic brain injury, the primary indication for oxygen therapy is to ensure adequate oxygen supply to the brain and prevent further neurological damage.
