Which step did Woo Jin get wrong and why? step 2, because you do not check for a pulse if you are not trained step 3, because you call 911 only after five minutes of not breathing step 5, because chest compressions should be hard and slow step 6, because CPR is done only until the call to 911 is made

The answer is (A) step 2, because you do not check for a pulse if you are not trained.

Explanation:

If you are not trained in CPR then checking for a pulse and checking wrong artery could result in a false flag and you may even make the situation worse than it already is. In order to prevent this mistake you need to wait for a professional to arrive on scene. Please mark Brainiest.
