1. What is the MOST effective way to prevent cardiopulmonary arrest in a newborn?

• A. Ensure effective oxygenation and ventilation.
• B. Administer blow-by oxygen as soon as the newborn is born.
• C. Perform an Apgar assessment every 5 minutes.
• D. Suction the newborn's mouth and nose every 3 minutes.

Correct answer: A

Rationale: The most effective way to prevent cardiopulmonary arrest in a newborn is to ensure effective oxygenation and ventilation. This is crucial in maintaining adequate oxygen supply and preventing respiratory distress or failure, which are significant factors leading to cardiopulmonary arrest. Providing appropriate ventilation support and oxygenation can help sustain the newborn's vital functions and reduce the risk of cardiopulmonary compromise.

2. In educating the parents of a child diagnosed with hypothyroidism, the nurse mentions that the child should avoid goitrogens. Which of the following will the nurse mention as an example?

• A. Orange
• B. Tomatoes
• C. Cabbage
• D. Grapes

Correct answer: C

Rationale: Cabbage is an example of a goitrogen that should be avoided in children with hypothyroidism. Goitrogens are substances that can interfere with thyroid function by inhibiting iodine uptake, potentially worsening the condition. Cabbage, along with other cruciferous vegetables like broccoli and cauliflower, contains compounds that can affect thyroid hormone production. Oranges, tomatoes, and grapes are not classified as goitrogens. Therefore, it is important for parents to be aware of foods like cabbage and to limit their child's intake to help manage their hypothyroidism effectively.

3. When a father asks why his child with tetralogy of Fallot seems to favor a squatting position, the nurse would explain that squatting:

• A. Increases peripheral vascular resistance
• B. Decreases arterial blood flow away from the heart
• C. It's a common resting position when a child is tachycardic
• D. Increases the workload of the heart

Correct answer: A

Rationale: Squatting increases systemic vascular resistance, which leads to a reduction in the right-to-left shunting of blood in children with tetralogy of Fallot. This helps improve oxygenation by balancing the pulmonary and systemic blood flow. The squatting position decreases the pressure in the right ventricle and reduces the magnitude of the right-to-left shunt by increasing afterload, thereby improving oxygenation. Choices B, C, and D are incorrect because squatting does not decrease arterial blood flow away from the heart, is not related to being tachycardic, and does not increase the workload of the heart.

4. Which of the following parameters is the LEAST reliable when assessing the perfusion status of a 2-year-old child?

• A. Capillary refill time
• B. Presence of peripheral pulses
• C. Skin color and temperature
• D. Systolic blood pressure

Correct answer: D

Rationale: Systolic blood pressure is the least reliable parameter when assessing perfusion status in a 2-year-old child. In young children, blood pressure measurements can be variable, affected by factors like anxiety or crying. Capillary refill time, presence of peripheral pulses, and skin color and temperature are more reliable indicators of perfusion status in this age group.

5. Your assessment of a 5-year-old child reveals that he is unresponsive with a respiratory rate of 8 breaths/min and a heart rate of 50 beats/min. Treatment for this child should include:

• A. high-flow oxygen via non-rebreathing mask and rapid transport.
• B. assisted ventilation with a bag-mask device and rapid transport.
• C. positive-pressure ventilation, chest compressions, and rapid transport.
• D. back slaps and chest thrusts while attempting artificial ventilations.

Correct answer: C

Rationale: In a 5-year-old child who is unresponsive with severe bradycardia and bradypnea, the priority is to provide positive-pressure ventilation to support breathing and perform chest compressions to support circulation. This child is in cardiac arrest, and the recommended treatment according to pediatric basic life support guidelines involves a combination of positive-pressure ventilation and chest compressions to maintain oxygenation and circulation. Rapid transport to a medical facility for further advanced care is crucial in this critical situation. Choices A, B, and D are incorrect because high-flow oxygen via non-rebreathing mask, assisted ventilation with a bag-mask device, and back slaps with chest thrusts are not sufficient in a cardiac arrest situation where the child requires immediate positive-pressure ventilation and chest compressions to maintain oxygenation and circulation.
