The nurse understands the rationale for utilizing N-acetylcysteine for acetaminophen ingestions in children is to:
treat bacterial infections
promote coughing and clear secretions
reduce pain and fever
prevent liver damage
The Correct Answer is D
A. Treat bacterial infections – Incorrect. N-acetylcysteine is not an antibiotic.
B. Promote coughing and clear secretions – Incorrect. This describes its use in cystic fibrosis as a mucolytic, not in acetaminophen toxicity.
C. Reduce pain and fever – Incorrect. Acetaminophen, not N-acetylcysteine, is used for pain and fever.
D. Prevent liver damage – Correct. N-acetylcysteine replenishes glutathione stores, which helps detoxify acetaminophen metabolites that cause hepatotoxicity.

Correct Answer is ["70"]
Explanation
The nurse should withhold digoxin if the child's apical heart rate is less than 70 beats per minute because digoxin slows the conduction of electrical signals in the heart and increases the force of cardiac contraction. While this helps to treat conditions like heart failure and arrhythmias, it can also lead to bradycardia. Administering digoxin when the heart rate is already too low increases the risk of adverse effects like severe bradycardia or even cardiac arrest.
Correct Answer is B
Explanation
A. "Use lotion or powder inside the cast to prevent itching." – Incorrect. Lotions and powders can increase moisture, leading to skin irritation or infection.

C. "Massage the baby’s foot to improve circulation while the cast is on." – Incorrect. Massage is not recommended as it may interfere with alignment.
