Pediatric HESI Practice Questions

Correct Answer: B

Rationale: The correct answer is 'Hormonal secretion' (Choice B). The primary function of the endocrine system is to secrete hormones that regulate various bodily functions such as metabolism, growth, and reproduction. Choice A, 'Regulation of water balance,' is primarily controlled by the kidneys and the urinary system, not the endocrine system. Choice C, 'Cellular metabolism,' is more directly related to the functions of individual cells rather than the overall function of the endocrine system. Choice D, 'Growth stimulation,' is a function that can be influenced by hormones secreted by the endocrine system, but it is not the primary function of the system.

Correct Answer: D

Rationale: The most accurate way to determine a therapeutic dose for children is based on their weight rather than age. Weight-based dosing accounts for individual variations in drug metabolism and distribution, ensuring a more precise and safer medication administration. Choices A, B, and C are incorrect as they do not address the importance of weight-based dosing in children, potentially leading to inappropriate dosing and safety concerns.

Correct Answer: B

Rationale: The correct priority nursing intervention for a child diagnosed with diabetes insipidus is to monitor fluid balance. Diabetes insipidus is a condition characterized by excessive urination and thirst, which can lead to dehydration. Monitoring fluid balance is essential to prevent dehydration and ensure the child's hydration status remains stable. Administering insulin (Choice A) is not indicated in diabetes insipidus because it is a disorder of the posterior pituitary gland, not the pancreas. Administering diuretics (Choice C) would exacerbate fluid loss in a child already at risk for dehydration. Monitoring vital signs (Choice D) is important but not the priority when compared to maintaining fluid balance in a child with diabetes insipidus.

Correct Answer: D

Rationale: Poor wound healing is a common clinical manifestation of type 1 diabetes mellitus. High blood glucose levels in diabetes can impair the body's ability to heal wounds effectively. Choices A, B, and C are incorrect. Moist skin is not a typical clinical manifestation of type 1 diabetes; instead, skin may become dry due to dehydration. Weight gain is unlikely as type 1 diabetes is characterized by weight loss. Fluid overload is also uncommon in type 1 diabetes, which is more commonly associated with dehydration due to frequent urination.

Correct Answer: A

Rationale: When a child with nephrotic syndrome is undergoing treatment with corticosteroids, it is crucial to monitor for signs of infection. Corticosteroids can suppress the immune system, increasing the child's susceptibility to infections. Monitoring for signs of infection allows for early detection and prompt intervention, reducing the risk of complications. While monitoring blood pressure (choice B) is important in nephrotic syndrome, it is not the most immediate concern when the child is on corticosteroids. Monitoring for hyperglycemia (choice C) is relevant in corticosteroid therapy, but the priority in this scenario is to watch for signs of infection. Monitoring for hypertension (choice D) is important in nephrotic syndrome but is not the most critical consideration when the child is on corticosteroids.
