A nurse is caring for a client who is experiencing moderate anxiety and appears distracted and unable to focus. Which of the following actions should the nurse take?

Introduction: Moderate anxiety involves a narrowing of the perceptual field and selective inattention. Nursing interventions focus on redirecting excess motor energy and providing a calm, structured environment to help the client process information and regain emotional regulation before the anxiety escalates to a severe or panic state. A. Walking in the courtyard is an effective intervention for moderate anxiety. Gross motor activity helps dissipate the physiological tension associated with the "fight or flight" response. The rhythmic nature of walking, combined with a change of environment, can help ground the client and improve their ability to focus on the present moment. B. Escorting the client to a crowded dayroom is inappropriate for moderate anxiety. Increased environmental stimuli and social pressure can overwhelm a client whose perceptual field is already narrowed. Such an action is likely to increase the client's stress levels and potentially escalate the anxiety to a severe level. C. Escitalopram is a Selective Serotonin Reuptake Inhibitor (SSRI) used for the long-term maintenance of anxiety disorders. It has a delayed onset of action, typically taking 2 to 4 weeks to achieve therapeutic effects. It is not an appropriate medication for the acute management of an immediate anxiety episode. D. Antipsychotic medications are not the first-line treatment for moderate anxiety. These are potent agents with significant side effect profiles reserved for psychosis or extreme agitation. Moderate anxiety should first be managed with behavioral techniques or, if pharmacological intervention is necessary, short-acting benzodiazepines.
