A patient is having a seizure. What is the most appropriate step for the medical assistant to take to protect the patient?

In the context of a patient having a seizure, the most appropriate and effective action a medical assistant can take to protect the patient is to loosen any constrictive clothing, such as a tie. This action helps ensure that the patient can breathe freely and avoids any unnecessary restriction around the neck which could lead to choking or additional distress during the seizure.

Loosening clothing can help reduce the risk of injury by providing a safer environment for the patient as they experience the seizure. It is critical to maintain an area clear of any sharp or hard objects to minimize the chance of injury and to allow the seizure to occur safely without interference.

Restraint of the patient's movements is not advisable, as it can cause additional harm or lead to injuries. Placing a tongue depressor in the mouth carries risks, including damaging teeth or the gums, and could potentially lead to airway obstruction. While calling for help is important, the immediate action that directly aids the patient's safety during the seizure is loosening clothing to facilitate proper breathing and comfort.
