What term describes a therapy or device designed to preserve someone's life when an essential bodily system is not functioning?

• A. Palliative Care
• B. Life Support
• C. Rehabilitation
• D. Emergency Care

Answer: (B)

When a vital body system isn’t functioning, life support refers to therapies or devices that keep the person alive by sustaining those essential functions. This includes things like mechanical ventilation to help with breathing, dialysis to substitute kidney function, or other devices and treatments that support circulation or organ activity while the underlying problem is addressed or recovery is possible. The idea is to preserve life when the body isn’t able to do so on its own.

Palliative care, in contrast, focuses on comfort and quality of life rather than prolonging life with life-sustaining measures. Rehabilitation aims to restore or improve function after illness or injury. Emergency care is the immediate response to a sudden medical issue, not a long-term life-sustaining therapy.
