Which set of symptoms includes loss of equilibrium, perspiration, headache, nausea, and vomiting due to irregular motion?

• A. Motion Sickness
• B. Rhinitis
• C. Meniere's disease
• D. Symptoms of motion sickness

Answer: (D)

The symptoms described—loss of equilibrium, perspiration, headache, nausea, and vomiting—are the classic signs of motion sickness. This happens when motion signals confuse the brain, often due to a mismatch between what the eyes see and what the inner ear senses during irregular movement. Since the question asks for the set of symptoms, the phrasing that matches exactly is “symptoms of motion sickness.” Rhinitis would involve nasal symptoms like congestion and runny nose, not motion-related vomiting. Meniere's disease centers on vertigo with fluctuating hearing loss, tinnitus, and a feeling of fullness in the ear, not the typical motion-induced symptoms described here.
