In the case of a client found unresponsive and without vital signs, what is the nurse's immediate priority action?

• A. Contact the health care provider.
• B. Begin cardiopulmonary resuscitation (CPR).
• C. Monitor the client for a response.
• D. Administer oxygen immediately.

Answer: (B)

In a situation where a client is found unresponsive and without vital signs, the most critical and immediate action for the nurse is to begin cardiopulmonary resuscitation (CPR). This action is crucial because the absence of vital signs indicates that the client is not breathing and has no circulation, putting them at high risk of death if immediate intervention is not initiated. CPR is designed to maintain oxygenation and circulation to vital organs until advanced medical help can take over.

Starting CPR immediately can significantly increase the chances of survival and minimize the risk of brain damage due to lack of oxygen. Time is of the essence in such emergencies, and the prompt initiation of CPR can be life-saving.

The other actions, such as contacting the healthcare provider, monitoring for a response, or administering oxygen, are necessary but not the immediate priority. They can take place after CPR has commenced, as the primary focus must be on restoring circulation and breathing first.
