Pediatric HESI 2023

Correct Answer: B

Rationale: Live vaccines, like the measles, mumps, and rubella (MMR) vaccine, should not be administered to immunosuppressed infants, such as those undergoing chemotherapy. The weakened immune system of these infants may not be able to handle live vaccines safely, potentially leading to severe complications. Therefore, it is crucial to avoid giving live vaccines like MMR to infants receiving chemotherapy. Choice A is incorrect as delaying the MMR vaccine until the infant reaches 2 years of age is not the main concern in this scenario. Choice C is incorrect because although MMR vaccination is important for disease prevention, it should not be given to immunosuppressed infants. Choice D is incorrect as immediate action is needed to prevent potential harm from live vaccines in immunosuppressed infants.

Correct Answer: D

Rationale: The most crucial factor in successful toilet training is the parents' commitment to consistently work with their child. While parents' attitude and willingness are important, the key is their dedication to the process. The child's motivation and ability are also significant but rely heavily on parental guidance and support. Therefore, the correct choice is the parents' commitment to work on toilet training.

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.

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: B

Rationale: Edema is a hallmark clinical manifestation of nephrotic syndrome. In nephrotic syndrome, there is increased glomerular permeability leading to the loss of proteins, particularly albumin, in the urine. This results in decreased oncotic pressure, leading to fluid shifting into the interstitial spaces and causing edema. Jaundice (Choice A) is not a typical clinical manifestation of nephrotic syndrome. Hypertension (Choice C) is more commonly associated with conditions like glomerulonephritis. Polyuria (Choice D) is not a primary symptom of nephrotic syndrome; instead, patients may have reduced urine output due to fluid retention from edema.
