A nurse in a mental health facility is caring for a client who reports palpitations and a sense of impending doom. Which of the following actions should the nurse take first?

The client is experiencing palpitations and a sense of impending doom, which may indicate a heightened state of anxiety or a panic attack. Minimizing environmental stimuli can help create a calming and safe environment for the client. By reducing noise, bright lights, and other potentially distressing stimuli, the nurse can create a more soothing atmosphere that may help alleviate the client's anxiety. While exploring behaviors that have helped to reduce the client's anxiety in the past and explaining to the client that anxiety causes physical manifestations are important actions, they may not provide immediate relief or address the client's immediate distress. Administering an anti-anxiety medication may be considered if the client's symptoms persist or worsen, but it is not the first action to be taken. The nurse should prioritize non-pharmacological interventions and create a supportive environment before considering medication administration.
