HESI Pediatrics Quizlet

Correct Answer: B

Rationale: High fever is a key clinical manifestation of bacterial meningitis due to the inflammatory response in the meninges. Photophobia, choice A, is also commonly observed due to meningeal irritation, but it is not as specific as high fever. Rash, choice C, is more indicative of conditions like meningococcal meningitis rather than bacterial meningitis. Nasal congestion, choice D, is not typically associated with bacterial meningitis. Therefore, the correct answer is B.

Correct Answer: A

Rationale: The correct answer is A: 'It is a condition affecting the respiratory and digestive systems.' Cystic fibrosis is a genetic disorder that primarily affects the respiratory and digestive systems. It is caused by a defective gene that leads to the production of thick and sticky mucus in these organs. This mucus can clog airways in the lungs and block the ducts in the pancreas, affecting digestion. Choice B is incorrect because cystic fibrosis is not an autoimmune disorder; it is a genetic condition. Choice C is partially correct in that cystic fibrosis is a genetic disorder, but merely managing it with medication oversimplifies the comprehensive care needed for individuals with cystic fibrosis. Choice D is incorrect as cystic fibrosis is not caused by prenatal exposure to toxins but is a genetic condition inherited from parents.

Correct Answer: C

Rationale: The correct clinical manifestation the healthcare provider is likely to observe in a child with suspected intussusception is abdominal distension. Intussusception involves one portion of the intestine telescoping into another, causing obstruction. Abdominal distension is a common symptom due to the obstruction and buildup of gas and fluid in the affected area. While projectile vomiting can occur, it is not as specific to intussusception as abdominal distension. Currant jelly stools, which are stools containing blood and mucus, are a classic sign of intussusception but are not a clinical manifestation observable on assessment. Constipation is not typically associated with intussusception, as this condition often presents with symptoms of bowel obstruction rather than constipation.

Correct Answer: A

Rationale: Monitoring liver function tests regularly is crucial when a child with JIA is on methotrexate due to the potential hepatotoxicity associated with this medication. Methotrexate can lead to liver damage, hence monitoring helps in early detection and intervention. Encouraging regular exercise (Choice B) is generally good for children with JIA to maintain joint mobility and muscle strength, but it is not directly related to methotrexate therapy. Providing high-calorie snacks (Choice C) is not a priority consideration for a child on methotrexate. Encouraging frequent handwashing (Choice D) is important for infection control, but it is not specifically associated with methotrexate therapy in a child with JIA.

Correct Answer: D

Rationale: The major characteristic of a cardiac malformation associated with left-to-right shunting is increased blood flow to the lungs. This increased flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a typical characteristic of this condition. Severe growth retardation (Choice B) is not directly associated with left-to-right shunting. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions involving chronic hypoxia.
