Pediatric HESI Practice Questions

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: B

Rationale: For a child with a disorder of the posterior pituitary gland, desmopressin acetate is a medication commonly used to manage the condition by replacing the antidiuretic hormone. Instructing the parents on how to administer desmopressin acetate correctly is essential for the child's care. Choice A is incorrect because growth hormone treatment is not typically used for posterior pituitary disorders. Choice C is incorrect as treatment for this condition usually continues beyond puberty. Choice D is incorrect as acute adrenal crisis is not directly related to a disorder of the posterior pituitary gland.

Correct Answer: B

Rationale: Administering factor VIII in the morning on scheduled days ensures that there is a consistent level of the plasma component throughout the day, especially when the child is active. This timing helps to maintain adequate levels of factor VIII to prevent bleeding episodes. Choice A is incorrect because administering factor VIII only when a bleed is suspected would not provide the consistent prophylactic coverage needed for children with hemophilia. Choice C is incorrect as bedtime administration may not be practical for ensuring the plasma component is available during the child's active hours. Choice D is incorrect because administering factor VIII on a regular schedule, rather than at specific times of the day, may not optimize its effectiveness in preventing bleeding episodes.

Correct Answer: B

Rationale: In the scenario described, the priority is to relieve pressure from the umbilical cord protruding from the vaginal opening by gently pushing it back inside using your gloved fingers. This action helps prevent cord compression, maintains blood flow to the fetus, and ensures fetal oxygenation. Massaging the uterus (Choice A) is not appropriate in this situation as it can potentially worsen the cord compression. Placing the mother on her left side and providing rapid transport (Choice C) can be considered after relieving the pressure on the cord. Elevating the mother's lower extremities and providing immediate transport (Choice D) is not the correct approach when dealing with a visible umbilical cord; instead, the focus should be on relieving pressure from the cord to prevent fetal compromise.

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.
