Under what circumstance should oxygen not be withheld from a patient?

• A. If the patient is hypoxic or shows signs of poor oxygenation.
• B. If the patient requests not to receive oxygen.
• C. Oxygen should always be withheld to prevent toxicity.
• D. Only if SpO2 is above 95%.

Answer: (A)

When there is evidence of hypoxia or poor oxygenation, oxygen should be given. The immediate goal in emergency care is to restore adequate oxygen delivery to tissues, so if the patient’s SpO2 is low or they show signs such as confusion, cyanosis, tachypnea, or use of accessory muscles, withholding oxygen would worsen tissue hypoxia. Oxygen is a medication used to correct low oxygen levels, and while there are considerations about giving too much oxygen in certain chronic conditions, the priority in someone who is hypoxic is to provide it.

The other scenarios don’t fit because patient request not to receive oxygen isn’t enough to override an evident need for oxygen in an emergency, claiming oxygen should always be withheld to prevent toxicity ignores the immediate danger of hypoxia, and basing administration on an SpO2 above 95% contradicts the purpose of treating hypoxemia.
