A nurse is reinforcing teaching with a client who has chronic stress.Which of the following instructions should the nurse provide?

Choice A rationaleEngaging in regular physical activity helps to reduce the physiological effects of chronic stress by releasing endorphins, which have mood-boosting and pain-relieving effects. Exercise also improves cardiovascular health, reduces muscle tension, and promotes better sleep, all of which are negatively impacted by prolonged stress.Choice B rationaleConsuming a moderate amount of caffeine can provide a temporary boost in alertness and energy; however, it can also exacerbate anxiety, interfere with sleep patterns, and increase heart rate, potentially worsening the physiological symptoms of chronic stress in the long run. Its effects are highly individual.Choice C rationaleLimiting exercise close to bedtime is important because physical activity stimulates the body and can make it harder to fall asleep. Engaging in exercise too close to sleep can elevate heart rate and body temperature, counteracting the body's natural preparation for rest. It is generally recommended to finish strenuous activity at least a few hours before sleep.Choice D rationaleAiming for approximately 7-9 hours of sleep per night is crucial for managing chronic stress. Adequate sleep allows the body and mind to recover, improves mood regulation, enhances cognitive function, and strengthens the immune system, all of which are compromised by chronic stress and essential for resilience.
