Pediatric HESI Practice Questions

Correct Answer: A

Rationale: A webbed neck is a classic physical characteristic seen in individuals with Turner syndrome, a genetic condition that results from a missing or partially missing X chromosome in females. This distinctive feature occurs due to excess skin on the neck and is a key clinical clue for healthcare providers. Microcephaly (choice B) refers to a small head size and is not typically associated with Turner syndrome. Gynecomastia (choice C) is the enlargement of breast tissue in males and is not a common finding in Turner syndrome. Cognitive delay (choice D) involves intellectual or developmental delays and is not a specific feature of Turner syndrome.

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 a nonspecific test for inflammation and not specific to atopic dermatitis. Choice B, potassium hydroxide prep, is used to diagnose fungal infections like tinea versicolor, not atopic dermatitis. Choice C, wound culture, is not typically indicated for the diagnosis of atopic dermatitis as it is a chronic inflammatory skin condition rather than an infectious process.

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.

Correct Answer: A

Rationale: The correct answer is A: Incisors. In infants, incisors are usually the first teeth to erupt, typically around 6 months of age. These are the front teeth used for cutting food. Canines (Choice B), upper molars (Choice C), and lower molars (Choice D) typically erupt after the incisors. Canines are sharp teeth used for tearing food, while molars are flat teeth used for grinding food.

Correct Answer: B

Rationale: In the scenario described, when the umbilical cord is visible at the vaginal opening, the priority is to relieve pressure from the cord with gloved fingers. This action helps prevent cord compression and ensures continued oxygenation to the fetus, which is crucial for the baby's well-being. Massaging the uterus or elevating the mother's lower extremities is not the correct course of action in this situation and may potentially worsen the condition. Placing the mother on her left side and providing rapid transport is not the immediate step needed to address the visible umbilical cord; relieving pressure from the cord takes precedence to maintain fetal oxygen supply.
