1. What action should you take if a newborn's heart rate is 50 beats/min?

• A. Begin chest compressions.
• B. Reassess in 30 seconds.
• C. Administer blow-by oxygen.
• D. Start positive-pressure ventilations.

Correct answer: D

Rationale: If a newborn's heart rate is below 60 beats per minute, the appropriate action is to start positive-pressure ventilations. Ventilations help deliver oxygen to the newborn's body and support respiratory function, which is critical in cases of bradycardia. Chest compressions are not recommended until the heart rate is below 60 despite adequate ventilation. Reassessment is essential but not the immediate action required in this scenario. Administering blow-by oxygen alone may not effectively address the underlying cause of bradycardia, making positive-pressure ventilations the priority intervention in this case.

2. What advice should a school-age child with type 1 diabetes mellitus follow to prevent hypoglycemia during soccer practice?

• A. Drink a cup of orange juice before soccer practice
• B. Eat twice the amount normally eaten at lunchtime
• C. Take half the amount of prescribed insulin on practice days
• D. Take the prescribed insulin at noontime rather than in the morning

Correct answer: A

Rationale: Drinking orange juice before soccer practice is recommended to prevent hypoglycemia in children with type 1 diabetes. Orange juice contains fast-acting carbohydrates that can quickly raise blood sugar levels if they drop during physical activity. Eating twice the amount normally eaten at lunchtime can lead to hyperglycemia, which is high blood sugar, rather than preventing hypoglycemia. Adjusting insulin doses should only be done under the guidance of a healthcare provider. Taking insulin at noontime rather than in the morning does not directly address preventing hypoglycemia during afternoon soccer practice.

3. The caregiver is teaching a new mother about infant safety. Which statement indicates that further teaching is needed?

• A. I will place my baby on their back to sleep.
• B. I will keep soft toys and pillows out of the crib.
• C. I will use a car seat for every car ride.
• D. I will allow my baby to sleep in my bed.

Correct answer: D

Rationale: Allowing a baby to sleep in an adult bed increases the risk of suffocation and Sudden Infant Death Syndrome (SIDS). It is safer for infants to sleep on a firm, flat surface in their own crib or bassinet to reduce the risk of accidental suffocation or strangulation. Therefore, the caregiver should be advised against co-sleeping with the infant to ensure the baby's safety.

4. Justine is admitted to the pediatric unit due to the occurrence of diabetic ketoacidosis signaling a new diagnosis of diabetes. The diabetes team explores the cause of the episode and takes steps to prevent a recurrence. Diabetic ketoacidosis (DKA) results from an excessive accumulation of which of the following?

• A. Sodium bicarbonate from renal compensation
• B. Potassium from cell death
• C. Glucose from carbohydrate metabolism
• D. Ketone bodies from fat metabolism

Correct answer: D

Rationale: Diabetic ketoacidosis (DKA) results from the excessive accumulation of ketone bodies from fat metabolism. During DKA, there is a lack of insulin leading to the breakdown of fat stores into fatty acids and their subsequent conversion into ketone bodies. These ketone bodies accumulate in the blood, leading to metabolic acidosis and the characteristic symptoms of DKA.

5. What percentage of total body surface area has been burned in a 5-year-old child who experienced partial-thickness burns to his head, anterior chest, and both upper extremities?

• A. 45%
• B. 63%
• C. 72%
• D. 54%

Correct answer: A

Rationale: According to the pediatric rule of nines, the head and neck represent 18%, the anterior chest and abdomen 18%, and each arm 9%. By adding these percentages (18% + 18% + 9% + 9% = 45%), we find that 45% of the total body surface area has been burned in this child.
