HESI Pediatrics Quizlet

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: B

Rationale: Encouraging deep breathing exercises is crucial preoperative teaching for a child scheduled for a tonsillectomy as it helps improve lung function and can prevent postoperative complications like pneumonia. Explaining the procedure in detail may heighten the child's anxiety, making it less ideal. While discussing hydration is important, it may not be the top priority for preoperative teaching for this specific procedure. Play therapy can reduce fear and anxiety, but encouraging deep breathing exercises directly contributes to better postoperative outcomes by enhancing respiratory function.

Correct Answer: A

Rationale: Asking about the daily routine is the most appropriate statement by the nurse in this scenario. It allows the nurse to gather important information about the family's schedule, feeding patterns, and overall care routine for the infant. This open-ended question helps the nurse assess the family's situation comprehensively and identify any areas where support may be needed. Choices B, C, and D are less appropriate as they do not focus on gathering relevant information about the family's routine and needs but rather make assumptions or ask about specific isolated events.

Correct Answer: D

Rationale: The correct answer is to teach seizure first aid to family members. This is crucial because family members need to know how to appropriately respond during a seizure to ensure the child's safety. Choice A has been corrected to emphasize that antiepileptic medication should be administered as prescribed, not just when a seizure occurs, to effectively manage the condition. Choice B, while important for overall health, is not directly related to seizure management. Choice C is not recommended as restricting activities may not prevent seizures and may hinder the child's quality of life.

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.
