Pediatric HESI 2024

Correct Answer: B

Rationale: The correct answer is the sweat chloride test. This test is crucial in diagnosing cystic fibrosis as it measures the amount of chloride in sweat, which is typically elevated in individuals with cystic fibrosis. A chest X-ray (Choice A) may show characteristic findings like hyperinflation or bronchiectasis, but it is not a definitive diagnostic test for cystic fibrosis. Pulmonary function tests (Choice C) may help assess lung function but are not specific for cystic fibrosis. Sputum culture (Choice D) may be used to identify specific pathogens causing respiratory infections but is not a primary diagnostic test for cystic fibrosis.

Correct Answer: B

Rationale: In today's diverse society, the concept of family has evolved beyond traditional definitions. Choice B, 'A family is whatever the child and family say it is,' reflects the contemporary understanding that families can take various forms, based on self-identification and individual perspectives. Choice A is too restrictive, as modern families may not solely consist of parents and their offspring living together. Choice C is somewhat inclusive but lacks the recognition of self-identification and diversity within families. Choice D focuses on genetic relation and roles, which may not apply to all modern family structures. Therefore, choice B is the most suitable and inclusive definition of a modern family in today's society.

Correct Answer: D

Rationale: Teaching seizure first aid to family members is crucial for ensuring the child's safety during a seizure. Keeping a diary of seizure activity (choice A) is important for tracking patterns and triggers but does not directly relate to immediate safety during a seizure. Administering antiepileptic medication only when a seizure occurs (choice B) is incorrect as medications should be given as prescribed to maintain therapeutic levels. Restricting the child's activities to prevent seizures (choice C) is not an appropriate approach as it may limit the child's quality of life without guaranteeing seizure prevention.

Correct Answer: D

Rationale: The correct answer is D: Preventing cardiac overload. Infants are highly vulnerable to fluid overload, making it essential to carefully monitor IV flow rates to prevent complications such as cardiac overload. Rapid administration of IV fluids can lead to an excessive increase in circulating volume, potentially causing cardiac strain or heart failure in infants. Choices A, B, and C are incorrect. Monitoring the IV flow rate is not primarily aimed at limiting output, replacing lost fluids, or avoiding IV infiltration in this scenario. The key concern is to prevent the risk of cardiac overload due to the infant's susceptibility to fluid imbalances.
