Which observation best indicates that oxygen therapy is improving a patient's oxygenation?
Correct answer: A. The patient becomes less restless and oxygen saturation rises
- A. The patient becomes less restless and oxygen saturation rises
- B. The patient reports increased thirst and a dry mouth
- C. The patient develops redness behind both ears
- D. The patient coughs once after the mask is applied
Explanation
Improved oxygen saturation together with reduced restlessness suggests better tissue oxygenation. Thirst, dry mouth, and pressure-area redness are possible treatment-related problems, not evidence that oxygenation has improved.
