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: B

Rationale: The priority nursing intervention for a 3-year-old child with Kawasaki disease is monitoring for coronary artery aneurysms. Kawasaki disease can lead to coronary artery complications, making early detection crucial in preventing serious outcomes. Administering IV immunoglobulin is a standard treatment for Kawasaki disease but does not take precedence over monitoring for potential complications. Encouraging fluid intake and providing nutritional support are important aspects of care but are not the priority when compared to monitoring for coronary artery aneurysms to prevent long-term cardiac issues.

Correct Answer: C

Rationale: The most appropriate nursing diagnosis for a child with acute glomerulonephritis is 'Fluid volume excess related to decreased plasma filtration.' Acute glomerulonephritis is characterized by inflammation in the glomeruli, leading to decreased plasma filtration and retention of fluid. This results in fluid volume excess rather than deficit, making choice C the correct answer. Choice A is incorrect because acute glomerulonephritis is not primarily associated with a malignant process. Choice B is incorrect as the condition typically presents with fluid volume excess rather than deficit. Choice D is also incorrect as fluid accumulation in tissues and third spaces is not a typical manifestation of acute glomerulonephritis.

Correct Answer: D

Rationale: During crowning, it is important to apply gentle pressure to the baby's head. This helps to prevent rapid delivery, which can lead to tearing and other complications for both the mother and the baby. Applying pressure also helps to control the delivery process, ensuring a safer and more controlled birth. Choices A, B, and C are incorrect because crowning does not signify the end of the second stage of labor, does not always occur immediately after the amniotic sac ruptures, and it is not safe to transport the patient during crowning, especially if the hospital is nearby, as rapid delivery can occur.

Correct Answer: C

Rationale: A moist sterile dressing should be used to protect the exposed bladder tissue from infection and injury. Exstrophy of the bladder requires careful management to prevent complications such as infection. A loose diaper (Choice A) may not provide adequate protection or prevent infection. Dry gauze dressing (Choice B) may not be ideal as it could adhere to the exposed area and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) may not be suitable as it can trap moisture and increase the risk of infection.
