Which following is a direct cardiovascular response commonly associated with vibration exposure?

• A. Dizziness
• B. Shortness of breath
• C. Increased pulse rate and blood pressure
• D. Nausea

Answer: (C)

When the body experiences vibration, the autonomic nervous system kicks in to maintain stability and perfusion. This sympathetic activation causes the heart to beat faster and the blood vessels to constrict, which raises the pulse rate and blood pressure. It’s a rapid, reflex response aimed at preserving blood flow to essential organs and muscles during the disturbance from vibration. Dizziness, shortness of breath, and nausea can occur with vibration exposure for various reasons—vestibular stimulation, anxiety, or respiratory effort—but they are not the immediate cardiovascular adjustments driven by autonomic arousal. The most consistent direct cardiovascular change you’ll see is an increase in heart rate and arterial pressure.
