A 47-year-old woman presents to the PMHNP with a chief complaint of anxiety. She is the primary caretaker for her 79-year-old mother, who has Alzheimer's disease. Which of the following tools will the nurse practitioner use to assess the client's level of anxiety?

Choice A reason: The Beck Anxiety Inventory is a self-report measure mainly used for screening anxiety in the general population, not specifically in clinical assessment settings requiring clinician-administered evaluation. Choice B reason: The HADS-A is used for screening anxiety and depression in medically ill patients but does not provide detailed gradation of anxiety severity. Choice C reason: The State-Trait Anxiety Inventory measures both temporary state anxiety and chronic trait anxiety but is primarily used for research and not preferred for clinical diagnostic assessment. Choice D reason: The Hamilton Anxiety Rating Scale is the most widely used clinician-rated tool to assess the severity of anxiety symptoms in psychiatric settings. It evaluates both somatic and psychological symptoms of anxiety, allowing for accurate assessment of symptom intensity and treatment response in clinical practice.
