Final answer:
Incorrect, you should continue providing CPR uninterrupted until help arrives or an AED is available, rather than leaving the individual alone after 2 minutes. Hence, option (b) false is the correct answer.
Step-by-step explanation:
The question concerns whether you should provide 2 minutes of CPR before leaving someone in presumed cardiac arrest to get help if you are alone without a means to communicate and no one has responded to your calls for assistance.
The correct response is 'false.' In a situation where an individual, like Maggie, is found in cardiac arrest and you are alone, guidelines advocate starting CPR immediately. After calling for help, if no one responds, you should continue delivering CPR uninterrupted until professional medical assistance arrives or an Automated External Defibrillator (AED) is available. AEDs are frequently found in public places and are crucial in delivering a shock to help restore normal heart rhythm during cardiac emergencies.
