Which of the following is true concerning CPR certification courses?

The correct choice highlights an important aspect of CPR certification courses in the context of dental hygiene regulations. While online learning has become increasingly prevalent, it is generally recognized that practical skills must be demonstrated to ensure competency in CPR. Therefore, having a portion of the course available online, alongside a hands-on component, strikes a balance between theoretical knowledge and practical application, which is essential in emergency situations.

This blend allows for the flexibility of learning while ensuring that participants can demonstrate their ability to perform CPR effectively. Practical skills are crucial, especially for healthcare professionals, as they need to react competently and confidently during emergencies. Thus, the requirement for a hands-on component confirms that individuals have not only learned the necessary theory but can also apply it in real-life scenarios, which is vital in providing safe patient care.
