What was the amount of oxygen administered to the patient?

The correct answer, indicating that 2 liters per minute (LPM) of oxygen was administered to the patient, reflects standard practices in emergency medical care. Administering oxygen at this rate is often utilized for patients who are experiencing mild to moderate respiratory distress, as it provides sufficient oxygenation without overwhelming the patient's respiratory system.

In general, oxygen therapy aims to achieve adequate oxygen saturation while avoiding potential complications from administering excessive oxygen. The choice of 2 LPM balances the need for supplemental oxygen with the patient's ability to breathe effectively. This rate is also commonly used to maintain comfort while monitoring the patient's response to therapy.

Other options, while they may represent different situations, do not align with the typical practices for managing similar patient conditions as effectively as the 2 LPM rate does.
