1. What is the MOST common cause of shock in infants and children?

A. Severe allergic reaction
B. Dehydration
C. Accidental poisoning
D. Cardiac failure

Correct answer: B

Rationale: Dehydration is the most common cause of shock in infants and children. In children, the body's fluid reserves are smaller compared to adults, making them more susceptible to dehydration, which can lead to shock if not promptly addressed. Severe allergic reactions, accidental poisoning, and cardiac failure can also cause shock, but dehydration is the most frequent cause in this age group.

2. What is the purpose of the pediatric assessment triangle?

A. Detect immediate life threats through a quick hands-on assessment.
B. Identify if the child has a medical condition or a traumatic injury.
C. Determine if the child's problem is respiratory or circulatory in nature.
D. Form a general impression of the child without touching them.

Correct answer: D

Rationale: The pediatric assessment triangle is used to form a rapid, hands-off general impression of the child's condition without directly touching them. This visual assessment helps in identifying children who require immediate attention and further evaluation.

3. Which of the following is the MOST detrimental effect of gastric distention in infants and children?

A. Tracheal rupture.
B. Less effective chest compressions.
C. Decreased ventilatory volume.
D. Acute rupture of the diaphragm.

Correct answer: C

Rationale: Gastric distention in infants and children can lead to a decrease in ventilatory volume. This occurs because the distended stomach can limit the movement of the diaphragm, reducing its ability to contract and expand the chest cavity effectively. As a result, the amount of air entering and leaving the lungs is decreased, impacting ventilation. Tracheal rupture, acute rupture of the diaphragm, and less effective chest compressions are not typically associated with gastric distention.

4. You are dispatched to a residence for a 5-year-old child who is not breathing. Upon arrival, you find the child supine on the floor, cyanotic, and unresponsive. You should first:

A. begin chest compressions.
B. open the airway and give two rescue breaths.
C. apply an AED and analyze the rhythm.
D. ask the parent for the child's medical history.

Correct answer: B

Rationale: When encountering an unresponsive and not breathing child, the initial step is to open the airway and provide two rescue breaths. This action helps to deliver oxygen to the child's lungs and body, which is crucial in attempting to restore breathing and circulation. Chest compressions are not initiated first in pediatric cases unless the child has no signs of circulation after delivering rescue breaths. Applying an AED and analyzing the rhythm is not the initial step in a pediatric cardiac arrest scenario, as the primary focus should be on providing oxygenation. Asking the parent for the child's medical history is not the immediate priority when the child is unresponsive and not breathing, as interventions to support breathing and circulation should be the primary concern.

5. A breastfeeding mother reports to the nurse that her newborn nurses every hour and never seems satisfied. Which advice should the nurse provide?

A. Supplement breastfeeding with formula after each nursing session.
B. Allow the newborn to nurse on each breast for at least 20 minutes.
C. Reduce the number of nursing sessions to every 2-3 hours.
D. Ensure the newborn has a proper latch and is effectively nursing.

Correct answer: D

Rationale: The nurse should ensure that the newborn has a proper latch and is effectively nursing. Sometimes, newborns nurse frequently for comfort even when they are effectively latched. It is essential to address the latch first before considering other interventions. Supplementing with formula (Choice A) may decrease the mother's milk supply. Allowing the newborn to nurse for a set time (Choice B) may not address the underlying latch issue. Reducing nursing sessions (Choice C) may lead to decreased milk production and does not address the latch problem.
