Pediatric HESI Practice Questions

Correct Answer: D

Rationale: The priority nursing intervention for a child with leukemia admitted to the hospital with a fever is to monitor for signs of infection. Children with leukemia are immunocompromised, making them more susceptible to infections. Monitoring for signs of infection helps in early detection and timely intervention, which is crucial in preventing complications. Administering antibiotics (choice A) may be necessary if an infection is suspected or confirmed, but the priority is to assess for signs of infection first. Administering antipyretics (choice B) may help reduce fever, but it does not address the underlying cause, which could be an infection. Providing nutritional support (choice C) is important for overall health but is not the priority when a child with leukemia presents with a fever, as infection needs to be ruled out or managed first.

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: 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 most accurate way to determine a therapeutic dose for children is based on their weight rather than age. Weight-based dosing accounts for individual variations in drug metabolism and distribution, ensuring a more precise and safer medication administration. Choices A, B, and C are incorrect as they do not address the importance of weight-based dosing in children, potentially leading to inappropriate dosing and safety concerns.
