A nurse is assisting in the care of a client who is experiencing excessive anxiety and worry in response to a variety of circumstances, and is unable to control their sense of worry. The nurse should identify that these manifestations indicate which of the following?

Choice A reason: Agoraphobia is the fear of being in places or situations where escape might be difficult, often leading to avoidance of public spaces. It does not involve persistent worry across multiple circumstances. Choice B reason: Panic disorder is characterized by recurrent, unexpected panic attacks with intense physical symptoms such as palpitations, chest pain, and fear of losing control. It is episodic rather than continuous worry. Choice C reason: Separation anxiety disorder is more common in children and involves excessive fear or anxiety about being separated from attachment figures. It does not match the description of generalized worry across circumstances. Choice D reason: Generalized anxiety disorder (GAD) is the correct diagnosis. It involves excessive, uncontrollable worry about various aspects of life, persisting for months, and often accompanied by physical symptoms such as restlessness, fatigue, and difficulty concentrating. The client’s inability to control worry across multiple circumstances fits this condition.
