What action should be taken for a patient experiencing symptoms of nitrous oxide overdose?

Providing supplemental oxygen is the appropriate action to take for a patient experiencing symptoms of nitrous oxide overdose. Nitrous oxide, while commonly used for its anesthetic and analgesic properties, can lead to a variety of adverse effects if administered in excessive amounts. Symptoms of overdose may include confusion, dizziness, nausea, or decreased respiratory function due to the potential for hypoxia.

In the case of an overdose, the primary concern is to ensure that the patient’s oxygen levels are restored to normal. Administering supplemental oxygen helps to counteract any hypoxia that may occur as a result of depleted oxygen levels due to the inhalation of nitrous oxide. By providing oxygen, it aids in restoring adequate systemic oxygenation, thereby alleviating symptoms associated with overdose.

Other actions, such as monitoring the patient quietly or calling for emergency assistance, might be appropriate in certain contexts, but they do not directly address the immediate need for oxygen, which is critical in an overdose situation. Administering additional nitrous oxide would exacerbate the problem rather than alleviate it. Therefore, providing supplemental oxygen is the best immediate response to support the patient in this scenario.
