For a patient undergoing dobutamine therapy (inotropic support), how should an exercise program be approached?

• A. Exercise should be continued as prescribed without modification.
• B. Exercise may need to be modified.
• C. Exercise is contraindicated and must be stopped immediately.
• D. Only passive range-of-motion activities are allowed.

Answer: (B)

Dobutamine changes how the heart responds to activity by boosting contractility and heart rate, so the exercise plan needs to be tailored and often toned down. The goal is to exercise within the patient’s current cardiovascular tolerance, which usually means gentler intensities, shorter sessions, and more rest, with careful monitoring of vital signs and symptoms. Use conservative targets—such as an easy-to-moderate effort with guidance from perceived exertion or a low heart-rate limit—and adjust based on how the infusion affects blood pressure, heart rate, chest pain, or dizziness. Work should be supervised and coordinated with the medical team, and be ready to modify or pause if signs of instability appear. Passive range-of-motion activities are not typically sufficient for a patient who can engage in more activity, unless mobility is severely limited.
