Pediatric HESI Practice Questions

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 the development of coronary artery aneurysms, which are one of the most serious complications of the disease. Early detection and monitoring of coronary artery changes are essential for prompt intervention and prevention of adverse outcomes. Administering IV immunoglobulin is an important treatment for Kawasaki disease, but monitoring for coronary artery aneurysms takes precedence as it directly impacts the child's long-term prognosis. Encouraging fluid intake and providing nutritional support are important aspects of care but are not the priority when compared to monitoring for potential life-threatening complications.

Correct Answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.

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: In a congenital cardiac malformation causing right-to-left shunting, the nurse should expect an elevated hematocrit. This occurs because the body compensates for decreased oxygenation by producing more red blood cells. Proteinuria (Choice A) is not typically associated with congenital cardiac malformations causing right-to-left shunting. Peripheral edema (Choice B) is more commonly seen in conditions causing left-sided heart failure. Absence of pedal pulses (Choice D) is not a typical finding in congenital cardiac malformations causing right-to-left shunting.

Correct Answer: B

Rationale: The correct answer is B: Epiphysis. Bone growth primarily occurs in the epiphysis, which is the area where growth plates are located. The epiphysis is responsible for longitudinal bone growth. Choice A, 'Growth plate,' is incorrect as it does not specify the exact area where bone growth primarily occurs. Choice C, 'Physis,' refers to the same structure as a growth plate, but the term 'epiphysis' is more specific to bone growth. Choice D, 'Metaphysis,' is incorrect as it is the area of the bone where the epiphysis meets the diaphysis, not the primary site of bone growth.
