Final answer:
The First Aid/CPR/AED Instructor certification is generally valid for 2 years, not 4 years, and instructors are required to seek recertification or training updates after this period.
Step-by-step explanation:
The statement that the First Aid/CPR/AED Instructor certification is valid for 4 years is false. In fact, this certification typically has a validity period of 2 years after which the instructor must usually undergo recertification or update training. The validity period is designed to ensure that instructors maintain their skills and knowledge up-to-date with the latest guidelines and best practices in first aid and resuscitation techniques.
