Which statement describes a contraindication or caution related to oxygen administration?

• A. SpO2 below 85%
• B. No contraindications exist
• C. Oxygen should be avoided in all patients
• D. Caution with SpO2 above 94%

Answer: (D)

Oxygen therapy is about treating low blood oxygen while avoiding giving more than the patient needs. When SpO2 is already high, pushing oxygen further can do more harm than good, so a caution to not overshoot is appropriate. Keeping SpO2 around recommended targets prevents hyperoxia, which can cause oxygen toxicity and, in certain patients like COPD, may worsen CO2 retention or lead to other complications. Therefore, the statement about being cautious when SpO2 is above 94% correctly reflects a management caution for oxygen administration. SpO2 well below 85% clearly indicates a need for oxygen to treat hypoxemia, not a caution. And there are real contraindications and clinical considerations for oxygen in specific patients; it’s not something to be avoided in all cases.
