What's the primary difference between compressions on an adult vs. a small child?
The child's chest wall is more easily compressed, so we shouldn't push as deep
We should use two hands on a small child and one hand on an adult
We may use one hand instead of two in order to compress the small child's chest
We should use three fingers for chest compressions on a child and five fingers on an adult

We may use one hand instead of two in order to compress the small child's chest.

Explanation:

Minimum depth of chest compression: compression depth for adults is a minimum of 5 cm/2 in. Compression depth for a child is at least ⅓ the depth of the chest size, or 5 cm for a child and 4 cm for an infant.

Because children have smaller chests than adults, the depth of compressions should be only one and a half inches. The compression and breath rate should be the same for children as for adults—30 compressions to two breaths.

lifetime activities are certain actions that are either required throughout your life or you choose to do them. for example, eating is considered a lifetime activity, drinking water or other beverages, keeping your body clean, taking medicine. those types of actions are considered lifetime activities.
