Which term refers to the blockage of all body sensations, causing unconsciousness and loss of reflexes?

• A. coronal plane
• B. general anesthesia
• C. enuresis
• D. dementia

Answer: (B)

Loss of all body sensations with unconsciousness and loss of reflexes is the medically induced state known as general anesthesia. This state is deliberately achieved for surgery so the patient does not feel pain, remains still, and cannot form memories of the procedure. Agents used may be inhaled gases, IV drugs, or a combination, and they produce unconsciousness, analgesia, and muscle relaxation. The other terms refer to different concepts: a coronal plane is an anatomical division of the body; enuresis means involuntary urination, typically during sleep; dementia is a chronic decline in cognitive function. Thus, the term that captures the complete loss of sensation, consciousness, and reflex activity is general anesthesia.
