A nurse is caring for a client who reports having insomnia due to increased stress. Which of the following actions should the nurse take first?

A. Determine the source of the client's stress: The first step in managing insomnia related to stress is assessing and identifying the underlying cause. Understanding the source allows the nurse to tailor interventions effectively and ensures that care addresses the root of the problem rather than just the symptoms. B. Instruct the client to turn off their TV just before they go to bed: Reducing screen time before sleep is helpful in promoting rest, but this is a specific behavioral strategy. It should follow an assessment of the client’s stressors and sleep patterns to be applied appropriately. C. Encourage the client to listen to soft music at the onset of stress: Relaxation techniques such as music therapy can aid stress reduction, but they are supportive measures. Without assessing the client’s unique stressors first, these interventions may not fully address the insomnia. D. Advise the client to exercise daily in the morning: Morning exercise can improve sleep quality and reduce stress, but it is a long-term strategy. The nurse must first explore the client’s stress triggers to ensure that interventions are individualized and effective.
