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: A

Rationale: The correct answer is A: Copying a square. At 3 years old, children should be able to copy a square as part of their fine motor skill development. The inability to perform this task may indicate a developmental delay in fine motor skills. Choice B, hopping on one foot, typically develops around 4-5 years of age, so it is not a reliable indicator of a delay at 3. Choice C, catching a ball reliably, involves coordination skills that develop later in childhood, making it less relevant for a 3-year-old assessment. Choice D, using a spoon effectively, is more related to self-care and feeding skills rather than fine motor development, so it is not the best indicator of a developmental delay in this context.

Correct Answer: C

Rationale: The correct answer is administering factor VIII. Hemophilia is a genetic disorder characterized by a deficiency in clotting factors, such as factor VIII. Administering factor VIII is crucial in managing bleeding episodes in hemophiliac patients. Pain medication (Choice A) may be necessary but is not the priority in this situation. Monitoring for signs of infection (Choice B) is important for overall care but is not the priority during a bleeding episode. Ensuring a safe environment (Choice D) is also important but not the priority intervention when managing a bleeding episode in a child with hemophilia.

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. While monitoring blood pressure, hyperglycemia, and hypertension are important considerations in certain conditions and treatments, they are not the primary concern when a child with nephrotic syndrome is on corticosteroid therapy.

Correct Answer: A

Rationale: The correct action would be to notify the doctor immediately. Unrelenting pain despite medication can indicate compartment syndrome, which is a medical emergency requiring immediate attention. Applying ice or elevating the arm may not address the potential serious underlying issue of compartment syndrome. Giving additional pain medication without further assessment could delay necessary intervention and potentially worsen the condition.
