Which precaution should a nurse take when a client experiences a seizure?

Loosening tight clothing around the neck during a seizure is a crucial precaution because it helps ensure that the client has adequate airflow and reduces the risk of injury or choking. Seizures can cause spasms or loss of control over certain body functions, and if clothing restricts the airway, it could lead to serious complications. By loosening such clothing, the nurse facilitates easier breathing and helps maintain the patient’s safety throughout the seizure episode.

The other options involve actions that could potentially increase the risk of harm to the patient. Securing a client with restraints is not advisable, as it can lead to further injury or discomfort during uncontrolled movements. Instructing a client not to move does not take into account that the seizure can impair their ability to comprehend or respond, and may inadvertently lead to feelings of panic or confusion. Leaving the client alone during a seizure is also dangerous, as it poses a risk of injury if they fall or have a prolonged seizure without monitoring for recovery or complications. Therefore, loosening clothing is the most appropriate and safest action.
