Final answer:
If cherry red livor mortis is observed, it indicates that the individual has passed away, and CPR would be ineffective. Emergency services should be contacted immediately. Moving the body or administering an antidote without professional assistance is not advised.
Step-by-step explanation:
Observing cherry red livor mortis is a sign that could be associated with carbon monoxide poisoning or cyanide toxicity, conditions that can cause confusion, nausea, and may lead to seizures or death. Cherry red livor mortis is a late sign, indicating that the individual has been deceased for some time. If you encounter someone who you suspect has been poisoned but is still alive, it is important to contact emergency services immediately (Option 3).
Performing CPR in a case where cherry red livor mortis is observed would not be appropriate, as it indicates that the victim has already been dead for a period of time, and CPR is only effective if the heart has recently stopped. Additionally, administering an antidote without an accurate diagnosis or professional medical assistance can be dangerous. Finally, moving the body should be avoided, as it can interfere with the scene and potentially contaminate evidence, which can hinder the efforts of the emergency services and law enforcement.
