Which sign may occur with ketamine exposure as an increase in respiration and heart rate?

Explanation:
Ketamine exposure commonly stimulates the sympathetic nervous system, which shows up as faster breathing and a faster, stronger heartbeat. This autonomic arousal happens because ketamine can increase circulating catecholamines and drive a dissociative state while preserving airway reflexes, yet still producing a noticeable rise in heart rate and respiratory rate. While other effects like a slight rise in body temperature or changes in coordination or reaction time can occur, the sign that matches an increase in both respiration and heart rate best reflects this sympathetic activation.
