Practice Question
A 52-year-old woman is admitted with dyspnea and discomfort in her left chest with deep breaths. She has smoked for 35 years and recently lost over 10 pounds. Her vital signs on admission are: HR 1 1 2, BP 1 38/82, RR 22, tympanic temperature 36.80C (98.20F), and oxygen saturation 94%. She is receiving oxygen at 2 L/min via a nasal cannula. Which vital sign reflects a positive outcome of the oxygen therapy?
Answer Choices:
Correct Answer:
Oxygen saturation: 96%
Rationale:
🟢 The goal of oxygen therapy is to improve oxygenation and maintain adequate tissue perfusion.
🟢 An increase in oxygen saturation from 94% to 96% demonstrates a positive therapeutic response.
🟢 The temperature is normal but unrelated to oxygen therapy.
🟢 The respiratory rate of 24 is still slightly elevated (tachypnea) and does not show direct improvement in oxygenation.
🟢 The blood pressure is within normal limits but is not a direct indicator of oxygen therapy effectiveness.
🟢 Monitoring SpO₂ (oxygen saturation) is the most accurate measure of oxygen therapy outcomes in this case.
