When a client ingests poison and starts convulsing, what is the nurse's priority action?

In the scenario where a client has ingested poison and is starting to convulse, the nurse's priority action is to check the latency of the client's airway. Ensuring that the airway is clear is the first step in managing a patient who is in distress, particularly during a convulsive episode. Any obstruction can lead to inadequate ventilation and oxygenation, which can exacerbate the situation and potentially lead to life-threatening consequences.

Convulsions may compromise a person's ability to maintain their own airway, leading to a risk of aspiration or suffocation. Therefore, evaluating the airway for obstruction must take precedence in emergency situations. If the airway is compromised, immediate interventions, such as suctioning or providing airway support, can be initiated.

Other actions, such as calling for help, providing oxygen, or administering activated charcoal, are important but come after ensuring that the airway is clear. Without a patent airway, these steps may not be effective and could result in serious complications. Thus, the priority action focuses on preserving the client's ability to breathe effectively.
