Pediatric HESI 2024

Correct Answer: D

Rationale: A common clinical manifestation of bacterial meningitis is a positive Kernig sign, which indicates meningeal irritation. Kernig sign is elicited when the leg is bent at the hip and knee at 90-degree angles, and pain and resistance are felt with extension at the knee due to inflamed meninges. Options A, B, and C are not typically associated with bacterial meningitis. A rash is more commonly seen in viral illnesses, photophobia can be present but is not specific to bacterial meningitis, and jaundice is not a typical clinical manifestation of this condition.

Correct Answer: D

Rationale: While catheterization can be uncomfortable, it does not typically result in long-term psychological harm, and obtaining a sterile specimen is important for accurate diagnosis.

Correct Answer: C

Rationale: Delayed physical growth is a common finding in most children with symptomatic cardiac malformations. This occurs due to inadequate oxygenation and nutrient supply to tissues as a result of the cardiac defect. Mental retardation (Choice A) is not typically associated with cardiac malformations unless there are complications affecting brain function. Inherited genetic factors (Choice B) may contribute to the development of cardiac malformations but are not a direct common finding in affected children. Clubbing of the fingertips (Choice D) is more commonly associated with chronic respiratory or cardiac conditions, not specifically cardiac malformations in children.

Correct Answer: B

Rationale: During a vaso-occlusive crisis in sickle cell anemia, ensuring adequate hydration is crucial because it helps to reduce the viscosity of the blood and prevent further sickling of the cells. Administering oxygen may be necessary in some cases to improve tissue oxygenation, but hydration is the priority to prevent complications. Monitoring vital signs is important, but hydration takes precedence during a vaso-occlusive crisis. Administering pain medication is important for pain management but does not address the underlying issue of vaso-occlusion.

Correct Answer: D

Rationale: The correct answer is D: Pulling to a stand. By 10 months of age, most infants should be able to pull themselves up to a standing position while holding onto furniture or other support. This milestone indicates good strength and coordination in the lower body. Choice A, Crawling, is typically achieved around 6-9 months of age. Choice B, Sitting without support, usually occurs around 6-8 months. Choice C, Standing with assistance, can typically be seen around 9-12 months, but pulling to a stand is a more advanced milestone expected by 10 months.
