Question

which victim would need only rescue breathing? agonal gasping with no pulse breathing with a weak pulse no breathing and no pulse no breathing and a pulse

Explanation:

Rescue breathing is used when a person has a pulse but is not breathing. Agonal gasping with no pulse and no breathing and no pulse would require CPR (compressions + breathing). Breathing with a weak pulse does not need rescue breathing as the person is already breathing. Only when there is a pulse but no breathing (no breathing and a pulse) is rescue breathing indicated.

Answer:

No breathing and a pulse
