1. Why is a prolapsed umbilical cord dangerous?

• A. The cord may be wrapped around the baby's neck, causing strangulation.
• B. The cord might pull the placenta from the uterine wall during delivery.
• C. The baby's head may compress the cord, cutting off its supply of oxygen.
• D. The mother may die of hypoxia due to compromised placental blood flow.

Correct answer: C

Rationale: A prolapsed umbilical cord is dangerous because the baby's head may compress the cord, cutting off its supply of oxygen. This compression can lead to oxygen deprivation, potentially causing significant harm to the baby. Immediate medical intervention is crucial in such cases to prevent adverse outcomes.

2. 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.

3. You arrive at a residence shortly after a 4-year-old boy experienced an apparent febrile seizure. The child is alert and crying. His skin is flushed, hot, and moist. His mother tells you that the seizure lasted about 2 minutes. You should:

• A. provide supportive care and transport.
• B. give him acetaminophen or ibuprofen.
• C. begin rapid cooling measures at once.
• D. allow the mother to take her child to the doctor.

Correct answer: A

Rationale: After a febrile seizure, the recommended course of action is to provide supportive care and transport the child to a medical facility. Supportive care may include ensuring a safe environment, monitoring the child, and seeking medical evaluation to determine the underlying cause of the seizure and appropriate management.

4. Your assessment of a newborn reveals cyanosis to the chest and face and a heart rate of 90 beats/min. What should you do first?

• A. Dry the infant briskly.
• B. Suction the mouth.
• C. Begin artificial ventilations.
• D. Begin chest compressions.

Correct answer: C

Rationale: In a newborn with cyanosis to the chest and face and a heart rate of 90 beats/min, the priority action is to begin artificial ventilations. A heart rate below 100 beats/min with cyanosis indicates a need for immediate respiratory support to improve oxygenation. Drying the infant briskly or suctioning the mouth may be necessary later but are not the initial priority. Chest compressions are not indicated as the heart rate is above 60 beats/min.

5. After an advanced airway device has been inserted in a 6-month-old infant in cardiopulmonary arrest, you should deliver ventilations at a rate of:

• A. 10 to 12 breaths/min.
• B. 12 to 20 breaths/min.
• C. 6 to 8 breaths/min.
• D. 8 to 10 breaths/min.

Correct answer: D

Rationale: The appropriate ventilation rate for an infant with an advanced airway is 8 to 10 breaths per minute.
