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.

Parents tell the nurse that their child keeps scratching the areas where he has poison ivy. The nurse's response should be based on which knowledge?
- A. Poison ivy does not itch and needs further investigation.
- B. Scratching the lesions will not cause a problem.
- C. Scratching the lesions will cause the poison ivy to spread.
- D. Scratching the lesions may cause them to become secondarily infected.
Correct Answer: D
Rationale: Scratching the lesions caused by poison ivy may result in them becoming secondarily infected. It is important to advise against scratching the affected areas to prevent the introduction of bacteria from under the fingernails or through broken skin, which can lead to infection. This can complicate the initial skin irritation caused by the poison ivy rash. Encouraging the child to avoid scratching and keeping the affected areas clean can help prevent secondary infections and promote healing.
