Question

to prepare for his quiz on cpr, woo jin listed the steps he learned in his online health class.

1. check for consciousness.
2. check for a pulse.
3. call 911.
4. perform 100–120 chest compressions per minute.
5. push hard and fast during compressions.
6. perform cpr until the person starts breathing or help comes.

woo jin got 5 out of 6 on his quiz.
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

Explanation:

To determine the wrong step, we analyze each option:

• For the first option (step 2): In CPR, untrained individuals should not check for a pulse (they may misinterpret or delay action), so this is a valid error.
• Step 3: Calling 911 should be done promptly, not after 5 minutes of no breathing, so this reasoning is wrong.
• Step 5: Chest compressions should be hard and fast (not slow), so the reasoning here is incorrect.
• Step 6: CPR is performed until help arrives or the person recovers, not just until 911 is called, so this reasoning is wrong.

So the correct error is in step 2 as untrained people shouldn't check for a pulse.

Answer:

A. step 2, because you do not check for a pulse if you are not trained
