1. Which position is MOST appropriate for a mother in labor with a prolapsed umbilical cord?

• A. Supine with legs elevated
• B. Supine with hips elevated
• C. Left lateral recumbent
• D. Left side with legs elevated

Correct answer: B

Rationale: The most appropriate position for a mother in labor with a prolapsed umbilical cord is supine with hips elevated. This position helps reduce pressure on the cord, preventing further complications and ensuring optimal blood flow to the fetus.

2. A 3-year-old female has had severe diarrhea and vomiting for 4 days. She is now unresponsive with rapid, shallow respirations and thready radial pulses. Her heart rate is 160 beats/min, and her oxygen saturation is 88%. You should:

• A. Ventilate her with a bag-valve mask.
• B. Start chest compressions.
• C. Administer high-flow oxygen via a non-rebreathing mask.
• D. Place her in the recovery position.

Correct answer: A

Rationale: In a pediatric patient presenting with unresponsiveness, rapid, shallow respirations, thready pulses, high heart rate, and low oxygen saturation, the priority is to ensure adequate oxygenation. Ventilating the child with a bag-valve mask is crucial in this scenario to support her breathing and improve oxygenation, as indicated by her low oxygen saturation and respiratory distress. Starting chest compressions is not indicated as the child has a pulse. Administering high-flow oxygen via a non-rebreathing mask may not be as effective as providing positive pressure ventilation with a bag-valve mask in this situation. Placing her in the recovery position is not appropriate when the child is unresponsive and in respiratory distress.

3. How will a ventricular septal defect affect blood flow?

• A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
• B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
• C. No shunting occurs due to high pressure in the left ventricle.
• D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.

Correct answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.

4. What characteristic indicates that a mass on a newborn's head is a cephalohematoma?

• A. The mass appears on the second day after birth.
• B. The mass grows larger when the newborn cries.
• C. The head appears asymmetrical.
• D. The mass is located on only one side of the head.

Correct answer: A

Rationale: A cephalohematoma typically appears between the first and second days after birth, making choice A the correct answer. It results from blood vessel rupture between a cranial bone and the periosteal membrane. Choices B, C, and D are incorrect because the growth of the mass when the newborn cries, asymmetrical head appearance, or the mass being located on only one side of the head are not specific indicators of a cephalohematoma.

5. Which of the following is MOST likely to occur in conjunction with a breech presentation?

• A. Vertex presentation
• B. Maternal hypertension
• C. Prolapsed umbilical cord
• D. Premature rupture of the amniotic sac

Correct answer: C

Rationale: In a breech presentation, where the baby's buttocks or feet present first, there is an increased risk of the umbilical cord slipping down alongside or below the presenting part, leading to a prolapsed umbilical cord. This is a serious complication that can compromise fetal blood flow and oxygenation, necessitating prompt intervention to prevent adverse outcomes. Choices A, B, and D are less likely to occur in conjunction with a breech presentation. Vertex presentation is the normal head-first presentation, maternal hypertension is a separate condition that may not be directly related to fetal presentation, and premature rupture of the amniotic sac can happen independently of the baby's presentation.
