Pediatric HESI 2023

Correct Answer: B

Rationale: The correct answer is B: Rolls over. At 6 months, most infants can roll over, increasing the risk of falls. It is important to emphasize to the parent the need for careful supervision to prevent accidents. While choices A, C, and D are also milestones in infant motor development, rolling over at this age poses a higher risk of accidents due to the increased mobility and potential for falls.

Correct Answer: C

Rationale: In a pediatric patient with an unconscious state, a respiratory rate of 8 breaths/min, and a heart rate of 50 beats/min, the appropriate management involves chest compressions, artificial ventilations, and rapid transport. These signs indicate severe respiratory and circulatory compromise, requiring immediate intervention to support breathing and circulation. Choice A (100% oxygen via a non-rebreathing mask) is not sufficient in this critical situation as the child requires more than just oxygen supplementation. Choice B (positive pressure ventilations with a BVM device) may be needed, but chest compressions are crucial in this scenario due to the presence of bradycardia. Choice D (back blows and chest thrusts) are not indicated for an unconscious child with respiratory and circulatory compromise; instead, immediate chest compressions are necessary to provide circulatory support.

Correct Answer: D

Rationale: Closure of the cleft palate is recommended before the age of 2 to prevent the development of faulty speech patterns. Performing surgery at a younger age helps avoid speech difficulties that may arise if the repair is delayed. Choice A is incorrect as it focuses on fear, not the developmental aspect. Choice B is incorrect as the eruption of molars is not the primary reason for early surgery. Choice C is incorrect because the difficulty of repair is not solely related to the width of the palate but also to speech development.

Correct Answer: A

Rationale: The correct answer is A. Surfactant therapy is explained to parents as a treatment that enhances the lungs' ability to exchange oxygen and carbon dioxide. This is essential for premature infants with respiratory distress syndrome (RDS) as it helps improve their respiratory function. Choices B, C, and D are incorrect because surfactant therapy primarily focuses on addressing lung function and is not related to sedation, apnea reduction, or fighting respiratory tract infections.

Correct Answer: C

Rationale: The correct answer is C. In fluid replacement therapy for burns, it is crucial to administer most of the volume during the first 8 hours to prevent shock and maintain perfusion. This rapid administration is essential to stabilize the child's condition. Choices A and B are incorrect because the initial fluid replacement in burns typically involves administering crystalloids, not colloids, and the fluid replacement is generally calculated based on the extent of the burn injury, not the type of burn. Choice D is incorrect as monitoring hourly urine output to achieve less than 1 mL/kg/hr is not recommended in burn patients; instead, urine output should be monitored to achieve 1-2 mL/kg/hr in children to ensure adequate renal perfusion.
