Practice Test 6

A 55-year-old male collapses while walking in a transit station. He has a history of hypertension and obesity. Bystander CPR is started. EMS arrives and confirms cardiac arrest. You ensure compressions are deep enough and at the correct rate, limit pauses for AED analysis, and coordinate ventilations with a BVM. You rotate compressors every 2 minutes to reduce fatigue. You follow AHA BLS adult guidelines for compression quality and teamwork during resuscitation.

What is the appropriate rate and depth for compressions during CPR for an adult?​

A 7-year-old collapses during a basketball game at school. Staff begins CPR and brings an AED. The child has no known medical problems. EMS arrives and confirms the child is unresponsive, not breathing normally, and pulseless. You continue CPR while the AED is powered on. Pediatric pads are available; you place them so they do not touch. You clear the patient during analysis and shock delivery, then resume compressions immediately. You follow AHA pediatric BLS guidance prioritizing high-quality CPR and early defibrillation when advised.
