Step-by-step explanation:
The nurse would most likely recommend the client exercise for 30 to 45 minutes, most days of the week, which aligns with health guidelines that suggest adults should engage in moderate-intensity aerobic activity for at least 150 minutes per week, spread throughout the week. This exercise regimen is beneficial for reducing stress, improving cardiovascular health, and providing various mental health benefits such as improving body image and self-esteem. Exercise need not be continuous; even noncontinuous exercise adding up to 30 minutes over the course of each day has been shown to confer significant health benefits.
