A nurse is discussing pressure ulcer staging with a newly licensed nurse. Which statement should the nurse use to describe a stage 3 pressure ulcer?

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.

Choice A rationale
The prone position, which involves lying flat on the stomach, is not typically recommended for a child with respiratory failure due to pneumonia. While prone positioning can be beneficial in

certain cases of severe acute respiratory distress syndrome, it does not generally allow for maximal lung expansion.
Choice B rationale
The supine position, which involves lying flat on the back, is not typically recommended for a child with respiratory failure due to pneumonia. This position can make it more difficult for the lungs to expand fully, potentially worsening respiratory distress.
Choice C rationale
The side-lying position is not typically recommended for a child with respiratory failure due to pneumonia. While this position can be comfortable for resting, it does not generally allow for maximal lung expansion.
Choice D rationale
The upright position is typically recommended for a child with respiratory failure due to pneumonia. Sitting upright can help to maximize lung expansion and improve oxygenation.
