A nurse in the emergency department is caring for a client who reports chest pain, headache, and shortness of breath. He continues to state, "I don't know why my wife left me." The client receives a diagnosis of anxiety. The nurse realizes the client's findings support which level of anxiety?

A. The client’s physical symptoms (chest pain, headache, shortness of breath) and statements about not understanding why his wife left indicate a panic level of anxiety, which is marked by intense physical and emotional distress. B. Moderate anxiety involves increased nervousness or slight discomfort but does not cause the severe physical symptoms seen in panic anxiety. C. Mild anxiety presents with slight restlessness or tension, without significant physical symptoms. D. Severe anxiety would involve significant impairment in thinking or perception but is more focused on a sense of being overwhelmed or immobilized, rather than exhibiting full panic symptoms.
