Pediatric HESI Practice Questions

Correct Answer: B

Rationale: The correct answer is B: Invasive burn cellulitis. Invasive burn cellulitis presents with the burn developing a dark brown, black, or purplish color with discharge and a foul odor. Burn wound cellulitis (choice A) typically involves redness, warmth, and swelling around the burn site. Burn impetigo (choice C) is a superficial infection characterized by honey-colored crusting. Staphylococcal scalded skin syndrome (choice D) is a condition caused by exotoxins from Staphylococcus aureus, leading to widespread skin peeling.

Correct Answer: B

Rationale: The correct answer is monitoring fluid balance. In a child with diabetes insipidus, the primary concern is excessive urination and fluid loss, which can lead to dehydration. Monitoring fluid balance is crucial to prevent dehydration and maintain electrolyte balance. Administering insulin (Choice A) is not indicated in diabetes insipidus, as this condition is not related to insulin deficiency. Administering diuretics (Choice C) should be avoided as it can exacerbate fluid loss in a child already at risk for dehydration. While monitoring vital signs (Choice D) is important, the priority intervention in this situation is monitoring fluid balance to prevent complications associated with dehydration.

Correct Answer: C

Rationale: The most appropriate nursing diagnosis for a child with acute glomerulonephritis is fluid volume excess related to decreased plasma filtration. Acute glomerulonephritis is characterized by inflammation of the glomeruli in the kidneys, leading to decreased plasma filtration and retention of fluid. This results in fluid volume excess rather than fluid deficit (choice B) or fluid accumulation in tissues and third spaces (choice D). The diagnosis of 'risk for injury related to malignant process and treatment' (choice A) is not directly related to the pathophysiology of acute glomerulonephritis.

Correct Answer: A

Rationale: The correct answer is monitoring fluid and electrolyte balance. Gastroenteritis is characterized by inflammation of the gastrointestinal tract, leading to fluid loss. Maintaining fluid and electrolyte balance is essential in managing gastroenteritis to prevent dehydration and electrolyte imbalances. Encouraging regular exercise (Choice B) is not a priority in the acute phase of gastroenteritis when the focus is on rehydration and symptom management. Administering antipyretics (Choice C) may be considered for fever management but is not the priority over monitoring fluid and electrolyte balance. Administering antibiotics (Choice D) is not routinely indicated for viral gastroenteritis, which is a common cause of the condition in children.

Correct Answer: B

Rationale: The correct technique for opening the airway of an infant with no suspected neck injury is to tilt the head back without hyperextending the neck. This method helps to keep the airway open without risking injury to the infant's delicate neck structures. Choice A, lifting up the chin and hyperextending the neck, can potentially harm the infant's neck. Choice C, gently lifting the chin while maintaining slight flexion of the neck, is not as effective as tilting the head back. Choice D is incorrect as infants require a different approach compared to older children or adults due to their anatomical differences.
