Final answer:
The correct answer is A) Rigor mortis. Rigor mortis is the stiffening of the muscles that occurs after death and is not a reason to stop or withhold resuscitative efforts.
Step-by-step explanation:
The correct answer is A) Rigor mortis. Rigor mortis is the stiffening of the muscles that occurs after death. It is not a reason to stop or withhold resuscitative efforts. Indicators of do-not-attempt-resuscitation (DNAR) status, such as a DNR order, medical bracelet or documentation, would be a valid reason to stop or withhold resuscitative efforts.
Threat to safety of providers is another valid reason to stop resuscitative efforts, as the safety of the medical personnel should be prioritized. Lastly, if resuscitation efforts have been unsuccessful for 20 minutes or more, it may indicate that further efforts would be futile and it would be appropriate to stop resuscitative efforts.
