HESI Pediatrics Quizlet

Correct Answer: A

Rationale: The correct answer is to 'Eat more food when planning to exercise more than usual.' Increased physical activity requires more energy, so additional food intake is necessary to prevent hypoglycemia. Choice B is incorrect because the method of insulin administration should not be altered based on physical activity. Choice C is incorrect as insulin timing should be consistent rather than based on anticipated exercise. Choice D is incorrect since relying on foods with sugar can lead to unstable blood sugar levels, which is not ideal for managing diabetes during exercise.

Correct Answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. This procedure reveals the absence of ganglion cells in the affected bowel segment, which is a hallmark of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for diagnosing Hirschsprung disease due to the risk of not accurately reaching the affected segment. Multiple saline enemas (Choice C) are not used to confirm the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a standard diagnostic procedure for Hirschsprung disease and does not provide the necessary information to confirm the absence of ganglion cells in the affected bowel segment.

Correct Answer: C

Rationale: The correct answer is C: Osgood-Schlatter disease. This condition is a common overuse injury that affects the knee. Osgood-Schlatter disease typically occurs in children and adolescents who are involved in activities that require frequent running, jumping, and kicking. It is characterized by pain, swelling, and tenderness at the tibial tuberosity, where the patellar tendon inserts into the tibia. Choice A, Dislocated radial head, is not an overuse disorder but rather a form of elbow injury where the head of the radius bone is displaced from its normal position. Choice B, Transient synovitis of the hip, is a self-limiting condition that causes hip pain and limping in children. It is not typically considered an overuse disorder. Choice D, Scoliosis, is a condition characterized by an abnormal lateral curvature of the spine. While it may be related to certain activities or postures, it is not primarily classified as an overuse disorder.

Correct Answer: C

Rationale: The correct answer is to 'Record the best of three attempts.' This method provides an accurate measure of peak expiratory flow using a peak flow meter. By taking the best of three attempts, the child and parents can obtain a more reliable assessment of the child's lung function. Choices A, B, and D are incorrect because using the device before taking medication, during asthma attacks, or after eating does not ensure an accurate measurement of peak flow, which is essential for managing asthma effectively. Monitoring peak flow regularly and accurately can help in adjusting asthma treatment plans and assessing response to medications.

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.
