Pediatric HESI 2024

Correct Answer: D

Rationale: A common clinical manifestation of bacterial meningitis is a positive Kernig sign, indicating irritation of the meninges. Rash (Choice A) is not typically associated with bacterial meningitis. Photophobia (Choice B) can be present but is more commonly seen in viral meningitis. Jaundice (Choice C) is not a typical clinical manifestation of meningitis and is more indicative of liver dysfunction.

Correct Answer: A

Rationale: Administering a bronchodilator is the priority intervention for a child experiencing an acute asthma exacerbation. Bronchodilators help to dilate the airways quickly, providing immediate relief by opening up the narrowed air passages in asthma. Antihistamines are not the first-line treatment for asthma exacerbations and may not address the underlying bronchoconstriction. Corticosteroids are important for long-term control of asthma but may take longer to have an effect compared to bronchodilators. Administering oxygen is essential for hypoxemia in asthma exacerbations, but the priority is to relieve bronchoconstriction promptly with a bronchodilator.

Correct Answer: C

Rationale: The correct answer is C: Hyperpigmentation and hypotension. These findings are classic signs of Addison disease, caused by adrenal insufficiency. Hyperpigmentation results from increased ACTH stimulating melanin production, and hypotension occurs due to mineralocorticoid deficiency. Choices A, B, and D are incorrect. Arrested height and increased weight are not typical of Addison disease. Thin, fragile skin and multiple bruises are seen in conditions like Cushing's syndrome, not Addison disease. Blurred vision and enuresis are not characteristic symptoms of Addison disease.

Correct Answer: C

Rationale: The correct answer is C: 'The energy that would have been expended on sucking is conserved.' Gavage feedings are necessary for infants with congenital heart defects as they help conserve the infant's energy by eliminating the need for sucking, which can be taxing for infants with cardiac issues. Choice A is incorrect because gavage feedings are not primarily used to limit vomiting. Choice B is incorrect as the speed of administration is not the main reason for gavage feedings in this case. Choice D is incorrect because the regulation of the quantity of nutritional liquid is not the primary rationale for gavage feedings in infants with congenital heart defects.

Correct Answer: B

Rationale: The correct answer is B: Covering the sac with saline-soaked nonadhesive gauze. This intervention is essential in caring for an infant with myelomeningocele as it helps prevent infection and maintains a moist environment around the sac before surgical repair. Positioning the infant supine with a pillow under the buttocks (Choice A) may be suitable for comfort but is not directly related to managing the myelomeningocele. Wrapping the infant snugly in a blanket (Choice C) and applying a diaper (Choice D) are not recommended as they can increase the risk of infection and damage to the sac.
