Which of the following is NOT a physical sign of death?

• A. Rigor mortis
• B. Putrefaction
• C. Resuscitation
• D. Dependent lividity

Answer: (C)

The correct answer is resuscitation because it is not a physical sign of death; rather, it is an action taken in an attempt to revive someone who is unresponsive and not breathing. Rigor mortis, putrefaction, and dependent lividity are all physical signs that indicate a body has ceased to function biologically.

Rigor mortis refers to the stiffening of the muscles after death due to chemical changes in the body, typically occurring several hours after death. Putrefaction involves the decomposition of the body, which is characterized by the breakdown of tissues and the production of gases that can lead to a foul odor. Dependent lividity, or hypostasis, is the pooling of blood in the lowest parts of the body due to gravity, which occurs after the heart has stopped beating. Together, these signs help medical professionals determine if a patient has indeed passed away, while resuscitation signifies the ongoing attempt to restore life.
