------------------------------------------------ Aaliyah is 11 years old and weighs 97 lbs. She shows signs of puberty, including breast development. What is the recommended depth for chest compressions in this case?

1) At least 2 inches (5 cm)
2) At least 2.4 inches (6 cm)
3) At least 3 inches (7.5 cm)
4) At least 3.5 inches (9 cm)

The recommended depth for chest compressions in CPR for an 11-year-old showing signs of puberty is at least 2 inches (5 cm) deep, with a compression rate of 100-120 per minute. So the correct answer is A.

Explanation:

For Aaliyah, who is 11 years old and exhibiting signs of puberty, the recommended depth for chest compressions during CPR (cardiopulmonary resuscitation) is at least 2 inches (5 cm) deep.

This guideline is based on the current standards for performing high-quality CPR, which emphasize the importance of achieving sufficient depth to compress the chest and circulate blood to the vital organs, especially the brain.

Compressions should also be performed at a rate of 100-120 compressions per minute, which can be timed to the beat of the song "Staying Alive".
