LPN Pediatrics

Correct Answer: D

Rationale: Given the mechanism of injury and the distance the child was thrown, a primary pelvic injury should be suspected due to the high impact and force. The pelvis is a common site for significant injury in such cases, and the distance the child was thrown indicates a high-energy impact that could lead to pelvic fractures or injuries.

Correct Answer: C

Rationale: Expiratory grunting is a significant sign of inadequate breathing and respiratory distress in infants. It indicates that the infant is struggling to exhale properly, which can be a sign of various respiratory issues, including lung problems or airway obstruction. Monitoring and recognizing this sign promptly can help in providing timely interventions to support the infant's breathing and prevent further complications.

Correct Answer: D

Rationale: A sudden onset of respiratory distress in a child without fever is most likely due to a foreign body airway obstruction. This obstruction can rapidly lead to difficulty breathing, stridor, and other signs of respiratory distress without necessarily causing a fever. Prompt recognition and intervention are crucial in such cases to prevent further complications and ensure the child's airway remains clear.

Correct Answer: B

Rationale: The presentation of wheezing, widespread hives, and facial edema is consistent with an allergic reaction. These symptoms indicate a systemic response to an allergen, triggering respiratory distress and skin manifestations.

Correct Answer: B

Rationale: When the work of breathing increases after elevating the legs, it is important to lower the extremities. Elevating the lower extremities in a child with signs of shock can worsen the condition by reducing venous return to the heart. Lowering the extremities can help improve venous return and potentially alleviate the increased work of breathing.
