Which is an appropriate action when an infant becomes apneic?
- A. Shake vigorously
- B. Roll head side to side
- C. Hold by feet upside down with head supported
- D. Gently stimulate trunk by patting or rubbing
Correct Answer: D
Rationale: When an infant becomes apneic (stops breathing), the appropriate action is to gently stimulate the trunk by patting or rubbing. This can help stimulate the infant to resume breathing. It is important to avoid any rough handling or shaking as this can cause harm to the infant. Rolling the head side to side or holding the infant by the feet upside down is not recommended in this situation and could potentially be dangerous. Gently stimulating the trunk is a safe and appropriate response to help the infant start breathing again.
