1. What is the most common cause of shock (hypoperfusion) in infants and children?

• A. infection
• B. cardiac failure
• C. accidental poisoning
• D. severe allergic reaction

Correct answer: A

Rationale: Infection is the leading cause of shock in infants and children due to their heightened vulnerability to sepsis. Infants and children possess developing immune systems, rendering them more susceptible to infections that can progress to septic shock. While cardiac failure is a severe condition, it is not as commonly the primary cause of shock in this age group. Accidental poisoning, though a potential shock inducer, is less prevalent in infants and children compared to infections. Severe allergic reactions, though significant, are not as frequent as infections in precipitating shock in infants and children.

2. You are managing a 10-month-old infant who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. You have initiated supplemental oxygen therapy and elevated the lower extremities. En route to the hospital, you note that the child's work of breathing has increased. What must you do first?

• A. Lower the extremities and reassess the child
• B. Begin positive pressure ventilations and reassess the child
• C. Place a nasopharyngeal airway and increase the oxygen flow
• D. Listen to the lungs with a stethoscope for abnormal breath sounds

Correct answer: A

Rationale: In this scenario, the infant is showing signs of shock with increased work of breathing. Lowering the extremities helps improve venous return to the heart, cardiac output, and oxygenation by reducing the pressure on the diaphragm. This action can alleviate the respiratory distress and is a critical step to take in a child with signs of shock. Beginning positive pressure ventilations (Choice B) should be considered if the infant's respiratory distress worsens despite lowering the extremities. Placing a nasopharyngeal airway and increasing oxygen flow (Choice C) may not directly address the increased work of breathing or the underlying shock condition. Listening to the lungs with a stethoscope (Choice D) may provide information on lung sounds but does not address the immediate need to improve breathing in a child with signs of shock.

3. Upon assessing a newborn immediately after delivery, you note that the infant is breathing spontaneously and has a heart rate of 90 beats/min. What is the most appropriate initial management for this newborn?

• A. begin positive pressure ventilations
• B. provide blow-by oxygen with oxygen tubing
• C. assess the newborn's skin condition and color
• D. start chest compressions and contact medical control

Correct answer: A

Rationale: A heart rate below 100 beats/min in a newborn indicates the need for positive pressure ventilation to improve oxygenation. Providing positive pressure ventilations helps in assisting the newborn's breathing efforts to ensure adequate oxygenation. Choice B, providing blow-by oxygen, may not be sufficient to address the underlying issue of inadequate breathing. Choice C, assessing the newborn's skin condition and color, is important but not the most immediate action needed for a heart rate below 100 beats/min. Choice D, starting chest compressions, is not indicated as the infant is breathing spontaneously and has a heart rate, albeit lower than normal, which does not warrant chest compressions.

4. The parent of a child who has received all of the primary immunizations asks the nurse which ones the child should receive before starting kindergarten. The nurse tells the parent that her child should receive boosters of:

• A. IPV, HepB, Td.
• B. DTaP, HepB, Td.
• C. MMR, DTaP, Hib.
• D. DTaP, IPV, MMR.

Correct answer: D

Rationale: The correct answer is D: DTaP, IPV, MMR. Before starting kindergarten, the child should receive boosters of DTaP, IPV, and MMR to ensure ongoing protection against diphtheria, tetanus, pertussis, polio, measles, mumps, and rubella. Choice A is incorrect because it includes HepB instead of MMR. Choice B is incorrect as it includes HepB instead of MMR and DTaP instead of IPV. Choice C is incorrect as it includes Hib instead of IPV.

5. What is important to include in discharge instructions for a child who has had a tonsillectomy?

• A. Encourage the child to gargle with salt water
• B. Encourage fluid intake
• C. Provide the child with hard candy
• D. Apply heat to the neck

Correct answer: B

Rationale: Encouraging fluid intake is essential post-tonsillectomy to keep the throat moist, aid in healing, and prevent dehydration. Gargling with salt water may irritate the surgical site and is typically avoided to prevent discomfort and irritation. Providing hard candy can be harmful as it may cause trauma to the surgical area and should be avoided to prevent injury. Applying heat to the neck is not recommended as it can increase swelling and discomfort in the surgical region. Therefore, the correct instruction is to encourage fluid intake.
