Pediatric Practice Exam HESI

Correct Answer: B

Rationale: The correct preoperative teaching for a 2-year-old child undergoing surgery involves using a doll to demonstrate the procedure. This method helps the child understand what to expect in a non-threatening and visual way, making the experience less intimidating. Explaining the procedure in simple terms (Choice A) may not effectively convey the details to a young child. Showing pictures of the hospital environment (Choice C) may not directly address the surgical procedure itself. Allowing the child to play with medical equipment (Choice D) can be unsafe and may not effectively prepare the child for the surgery.

Correct Answer: A

Rationale: In a neonate with a suspected tracheoesophageal fistula, elevating the head but giving nothing by mouth is crucial to prevent aspiration. Placing the neonate in a semi-upright position helps reduce the risk of reflux and aspiration of gastric contents into the lungs. Elevating the head for feedings (Choice B) would still pose a risk of aspiration as the neonate may aspirate during feeding. Feeding glucose water only (Choice C) is not appropriate and does not address the risk of aspiration associated with a tracheoesophageal fistula. Avoiding suctioning unless the infant is cyanotic (Choice D) is incorrect because suctioning may be necessary for maintaining airway patency, regardless of cyanosis, in a neonate with a suspected tracheoesophageal fistula.

Correct Answer: A

Rationale: The correct answer is A. It is essential for both parents to inform the child about the divorce together, using age-appropriate language. This approach can help minimize the negative impact on the child by providing a sense of unity and understanding. Choice B is incorrect because offering false reassurance about love may not address the child's concerns effectively, as the situation is complex. Choice C is not suitable as engaging in special activities cannot substitute for the emotional stability that the child may lose due to the divorce. Choice D is incorrect because sharing the parent's feelings may burden the child with adult emotions, which could be overwhelming and confusing for their developmental stage.

Correct Answer: B

Rationale: The correct answer is B: 'Warmth at skin disruption site.' Cellulitis is characterized by localized warmth at the site of skin disruption, which indicates an infection. Choice A, 'Red, raised hair follicles,' is more typical of folliculitis. Choice C, 'Papules progressing to vesicles,' is suggestive of conditions like herpes simplex virus infections. Choice D, 'Honey-colored exudate,' is associated with impetigo, not cellulitis. When assessing cellulitis, nurses should primarily look for warmth, erythema, edema, and tenderness at the affected site.

Correct Answer: B

Rationale: The correct answer is B. Setting the water heater at 130 degrees is incorrect because water heaters should be set to no higher than 120 degrees to prevent scald burns. Choice A is correct as leaving fireworks displays to professionals reduces the risk of burns. Choice C is also correct as flame-retardant sleepwear reduces the risk of burn injuries. Choice D is correct as keeping pot handles facing inward prevents accidental spills and burns.
