Which of the following is NOT a way to determine death?

• A. Injury Pattern
• B. Pulse
• C. Rigor Mortis
• D. Lividity

Answer: (D)

Determining death relies on signs that life has ceased and on changes that occur after death. Lividity (livor mortis) is a postmortem change where blood pools in the dependent areas of the body after circulation stops; its presence confirms death and can help estimate time since death. Rigor mortis, another postmortem change, is the bodily stiffening that follows death and also indicates death has occurred. A pulse is a direct measure of life, so its absence supports that death has occurred. An injury pattern, by contrast, describes how injuries happened and what tissues were damaged. It informs mechanism and cause, not whether life signs are present at the moment of assessment. Because of that, injury pattern does not by itself determine death. So while lividity, rigor mortis, and pulse are used to decide if death has occurred, an injury pattern does not serve as a standalone method to determine death.
