HESI Pediatrics Quizlet

Correct Answer: D

Rationale: When caring for a child with acute laryngotracheobronchitis, the priority action should be to continually assess the respiratory status. This is crucial to detect early signs of respiratory distress, such as worsening stridor or increased work of breathing. Prompt intervention can prevent further deterioration of the child's condition. Initiating measures to reduce fever (Choice A) may be necessary but is not the priority in this situation. Ensuring delivery of humidified oxygen (Choice B) is important for maintaining oxygenation but should follow the assessment of respiratory status. Providing support to reduce apprehension (Choice C) is also important for the child's comfort but is not the priority over assessing and managing respiratory distress.

Correct Answer: A

Rationale: The correct answer is Varicella (chickenpox), choice A. Varicella can lead to the complication of encephalitis, which is the inflammation of the brain. Scarlet fever (choice B) is caused by Group A Streptococcus bacteria and does not typically lead to encephalitis. Poliomyelitis (choice C) is a viral infection that affects the nervous system but does not directly cause encephalitis. Whooping cough (choice D), also known as pertussis, primarily affects the respiratory system and does not commonly result in encephalitis.

Correct Answer: B

Rationale: The correct answer is B: High fever. In bacterial meningitis, a high fever is a common clinical manifestation due to the body's inflammatory response to the infection. While photophobia (choice A) is also a common symptom in meningitis, it is not as specific as a high fever. Rash (choice C) is more commonly associated with viral infections or other conditions, rather than bacterial meningitis. Nasal congestion (choice D) is not a typical clinical manifestation of bacterial meningitis and is more commonly seen in respiratory infections. Therefore, when assessing a child with suspected bacterial meningitis, the nurse is most likely to observe a high fever as a key clinical manifestation.

Correct Answer: A

Rationale: Seizures in children most often result from an abrupt rise in body temperature, leading to febrile seizures. Febrile seizures are common in young children and are typically triggered by a rapid increase in body temperature, often due to infections or other causes. An inflammatory process in the brain (Choice B) is less common as a cause of seizures in children and is usually associated with specific conditions like encephalitis or meningitis. While a temperature greater than 102�F (Choice C) may trigger a febrile seizure, it is the abrupt rise in temperature that is the primary cause. Choice D, a life-threatening infection, is a broad and less specific cause compared to the direct trigger of an abrupt rise in body temperature.

Correct Answer: C

Rationale: Osgood-Schlatter disease is a common overuse injury that specifically affects the knee. It is characterized by inflammation of the patellar ligament at the tibial tuberosity due to repetitive strain on the growth plate during activities such as running and jumping. Dislocated radial head (Choice A) is not an overuse disorder but rather an injury usually seen in young children. Transient synovitis of the hip (Choice B) is an acute hip condition and not typically classified as an overuse disorder. Scoliosis (Choice D) is a condition characterized by an abnormal lateral curvature of the spine and is not considered an overuse disorder.
