Final answer:
The nurse should best respond to a client having a panic attack by staying with them until the attack subsides, providing a sense of safety, presence, and reassurance without overwhelming them with information or instructions.
Step-by-step explanation:
When a client comes to the emergency department experiencing a panic attack, the nurse can best respond by: staying with the client until the attack subsides. This action conveys support and safety, helping to calm and reassure the client. In contrast, telling the client to lie down or that everything is under control may not be perceived as helpful and could potentially increase anxiety if the client feels misunderstood or invalidated. Continuously talking to the client, explaining what is happening, might be overwhelming and may not be effective if the client is unable to process information during the height of panic. Instead, simple and grounding techniques, such as deep breathing and mindfulness may be encouraged, coupled with a supportive presence.
The nurse can create a sense of safety by being present, demonstrating an understanding of the client's experience, and using comforting gestures, such as placing a hand on the client's shoulder, if appropriate. These actions suggest 'I'm here for you. It's ok to feel how you feel at this moment.' Acknowledging the client's feelings without overwhelming them with information or commands helps in stabilizing the situation and guiding the client towards recovery from the panic attack.
