A 23-year-old female complains of shortness of breath. She has a history of lupus. You observe a rash across both cheeks and the bridge of her nose. Her lungs are clear to auscultation. Her vital signs are P 88, R 20, BP 126/76, and SpO2 is 95% on room air. You should:

• A. apply cold packs to her rash.
• B. transport her in a position of comfort.
• C. administer oxygen.
• D. don an N-95 mask.

Answer: (C)

Providing supplemental oxygen addresses potential or evolving hypoxemia and helps ease shortness of breath. In someone with lupus, pulmonary involvement can occur (such as pleuritis, pneumonitis, or interstitial disease), so even if the lungs sound clear and the current SpO2 is 95% on room air, giving oxygen helps ensure adequate tissue oxygen delivery as the patient’s condition can change quickly. Oxygen is a low-risk, high-benefit intervention for respiratory distress and is prioritized over other options that don’t directly improve oxygenation. The other choices don’t target the primary immediate need here (supporting oxygenation): a rash treatment doesn’t address breathing, positioning alone may help but won’t treat hypoxemia, and an N-95 mask isn’t indicated without an infectious concern.
