What is the first step that may be taken if a person shows signs of rigor mortis?

When a person exhibits signs of rigor mortis, it indicates that biological death has occurred, which is characterized by the stiffening of muscles due to chemical changes in the body after death. Because rigor mortis sets in several hours after death, recognizing these signs is crucial for determining whether resuscitation efforts are appropriate.

Declaring a person dead is the necessary first action once rigor mortis is observed, as it legally confirms that the individual is no longer alive. Once a determination of death has been established, appropriate procedures can be initiated, such as notifying other authorities or family members, depending on local protocols.

Performing CPR or transporting the person to the hospital would be inappropriate actions at this stage because they are only applicable if the person shows signs of life. Notifying the next of kin is also a critical step but occurs after a person has been declared dead and is not the first action taken in response to signs of rigor mortis.
