Which skills are practiced only on a manikin for safety and educational quality?

The correct choice indicates that ventilations, chest compressions, and AED pad placement are skills practiced only on a manikin for safety and educational quality. This approach is essential as it allows trainees to focus on developing essential skills without risking injury to themselves or others.

Using a manikin ensures that students can practice these techniques repeatedly in a controlled environment where the manikin can simulate the necessary anatomical features without the complications that arise when practicing on a live person. Ventilations involve precise mouth-to-mouth or bag-valve-mask techniques, which require careful positioning and technique to ensure effectiveness without causing harm. Hands-on chest compressions need to be executed with the right depth and speed, which can be difficult to gauge without a manikin that provides instant feedback through visual indicators and, in certain scenarios, feedback devices.

Additionally, practicing AED pad placement on a manikin allows students to effectively learn the correct positioning of pads on the chest while ensuring that no electrical discharge can harm a live individual. This structured method promotes a safe learning environment and supports a deeper understanding of the skills, which are crucial in real-life emergency scenarios.

While there may be other skills pertinent to lifeguarding and CPR that can be practiced on live participants, the specific skills in this case
