1. 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.

2. What is the proper depth of chest compressions for a 9-month-old infant?

• A. 1/3 the diameter of the chest or about 1 1/2 inches.
• B. 1/4 the diameter of the chest or about 1 inch.
• C. 1/2 the diameter of the chest or about 2 inches.
• D. 1/3 the diameter of the chest or about 3/4 inch.

Correct answer: A

Rationale: When performing chest compressions on a 9-month-old infant, the proper depth is 1/3 the diameter of the chest, which equates to approximately 1 1/2 inches. This depth is crucial for effective cardiopulmonary resuscitation (CPR) in infants. Choice B, which suggests 1/4 the diameter of the chest or about 1 inch, is incorrect as it does not provide the recommended depth for infants. Choice C, stating 1/2 the diameter of the chest or about 2 inches, is too deep and may cause harm to the infant. Choice D, mentioning 1/3 the diameter of the chest or about 3/4 inch, is also incorrect as it underestimates the required depth for effective chest compressions on a 9-month-old infant.

3. 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.

4. Upon assessing a newborn immediately after delivery, you note that the infant is breathing spontaneously and has a heart rate of 80 beats/min. What is the MOST appropriate initial management for this newborn?

• A. Assess the newborn's skin condition and color.
• B. Initiate positive-pressure ventilations.
• C. Start chest compressions and contact medical control.
• D. Provide blow-by oxygen with oxygen tubing.

Correct answer: B

Rationale: In a newborn with a heart rate below 100 beats/min, the most appropriate initial management is to initiate positive-pressure ventilations. This helps support the newborn's respiratory effort and oxygenation in the setting of a low heart rate, ensuring adequate oxygen supply to vital organs. Assessing the skin condition and color, starting chest compressions, or providing blow-by oxygen are not the priority in this scenario where respiratory support is crucial.

5. 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.
