A nurse is caring for a patient with pneumonia who has been on oxygen therapy for several days.
Which of the following symptoms should the nurse recognize as a potential adverse effect of oxygen therapy?

Tachycardia.

Poor skin turgor.

Excessive pulmonary secretions.

Cracks in oral mucous membranes.

Answer and Explanation

The Correct Answer is D

Choice A rationale
Tachycardia is not a common adverse effect of oxygen therapy. It is more likely to be associated with conditions such as fever, anemia, or hypoxia.
Choice B rationale
Poor skin turgor is a sign of dehydration, not a typical adverse effect of oxygen therapy. Oxygen therapy does not directly affect the body’s hydration status.
Choice C rationale
Excessive pulmonary secretions are not a direct adverse effect of oxygen therapy. Conditions such as pneumonia or bronchitis often cause increased secretions.

Choice D rationale
Cracks in the oral mucous membranes can occur as a result of oxygen therapy. Oxygen can dry out the mucous membranes, leading to discomfort and potential cracking.
