Final Answer:
For adults and children 8 or over, AED pads should be placed in the anteroposterior placement, with one pad on the upper right chest and the other on the lower left side of the chest, making option (B) upper right chest and lower left side of the chest the correct answer.
Step-by-step explanation:
Anteroposterior pad placement for AED (Automated External Defibrillator) application involves positioning one pad on the upper right chest, just below the clavicle, and the other on the lower left side of the chest, below the armpit. This placement allows the AED to create a current that passes through the heart, facilitating defibrillation.
The upper right and lower left pad placement is recommended for both adults and children 8 years or older. This standardized approach simplifies the process for rescuers, ensuring consistency in pad positioning during a critical situation, such as sudden cardiac arrest.
