A child has small red macules and vesicles that become pustules around the child's mouth and cheek. Older lesions are crusted and honey-colored. What should the nurse teach the parents about this condition?
Notify the physician for any itching.
Keep the child home from school for 24 hours after starting antibiotics.
Keep the child home from school until the lesions are healed.
Clean the rash vigorously with Betadine three times a day.
The Correct Answer is B
A. Notifying the physician for itching is not necessary unless signs of secondary infection or worsening symptoms occur.
B. The child likely has impetigo, a highly contagious bacterial skin infection. Children can return to school 24 hours after starting antibiotic therapy, as the risk of transmission decreases significantly after this period.
C. Keeping the child home until lesions are fully healed is unnecessary and can prolong absence from school. Antibiotic treatment effectively reduces contagion before complete healing.
D. Vigorous cleaning with Betadine is not recommended, as harsh scrubbing can irritate the skin and worsen the lesions. Gentle cleansing and application of prescribed topical or systemic antibiotics are preferred.

Correct Answer is D
Explanation
A. Complex carbohydrates take longer to digest and raise blood glucose more slowly, which is not ideal for immediate treatment of mild hypoglycemia.
B. Glucagon is reserved for severe hypoglycemia when the child is unconscious or unable to take oral carbohydrates. The child in this scenario is alert and able to eat.
C. Administering insulin would further lower blood glucose and worsen hypoglycemia; this is contraindicated.
D. Giving 10 to 15 g of a simple carbohydrate (e.g., juice, glucose tablets) provides rapid absorption and quick correction of mild hypoglycemia. After 15 minutes, blood glucose should be rechecked and a complex carbohydrate snack may follow to maintain stability.
Correct Answer is B
Explanation
A. Maternal blood glucose assessment is unrelated to magnesium sulfate toxicity and would not address the immediate life-threatening issue.
B. Discontinuing magnesium sulfate is the priority because the client is showing signs of magnesium toxicity—respiratory depression and absent deep-tendon reflexes. Immediate cessation of the infusion prevents further complications. The nurse should also notify the provider and be prepared to administer calcium gluconate, the antidote for magnesium toxicity.
C. Preparing for cesarean birth may be necessary depending on maternal-fetal status, but the immediate threat is respiratory compromise from toxicity, which takes precedence.
D. Trendelenburg position does not correct magnesium toxicity and is not indicated; respiratory support and stopping the infusion are urgent priorities.
