Pediatric HESI Practice Questions

Correct Answer: C

Rationale: In a congenital cardiac malformation causing right-to-left shunting, the nurse should expect an elevated hematocrit. This occurs because the body compensates for decreased oxygenation by producing more red blood cells. Proteinuria (Choice A) is not typically associated with congenital cardiac malformations causing right-to-left shunting. Peripheral edema (Choice B) is more commonly seen in conditions causing left-sided heart failure. Absence of pedal pulses (Choice D) is not a typical finding in congenital cardiac malformations causing right-to-left shunting.

Correct Answer: D

Rationale: The varicella vaccine is specifically designed to prevent chickenpox. Measles, mumps, and rubella are prevented by different vaccines: Measles is prevented by the measles, mumps, and rubella (MMR) vaccine; Mumps is prevented by the MMR vaccine; and Rubella is also prevented by the MMR vaccine. Therefore, the correct answer is D, Chickenpox, as it is the disease prevented by the varicella vaccine.

Correct Answer: B

Rationale: Establishing a bedtime routine is the most appropriate suggestion for a child experiencing night terrors. Consistent bedtime routines help create a sense of security and predictability, reducing the likelihood of night terrors. Encouraging the child to talk about the dream (Choice A) may not be effective as night terrors occur during non-REM sleep, and the child may not remember the dreams. Allowing the child to sleep with the parents (Choice C) can reinforce dependency and may not address the underlying causes of night terrors. Waking the child during the night (Choice D) can disrupt their sleep cycle and worsen the occurrence of night terrors.

Correct Answer: A

Rationale: The correct answer is A: Incisors. In infants, incisors are usually the first teeth to erupt, typically around 6 months of age. These are the front teeth used for cutting food. Canines (Choice B), upper molars (Choice C), and lower molars (Choice D) typically erupt after the incisors. Canines are sharp teeth used for tearing food, while molars are flat teeth used for grinding food.

Correct Answer: C

Rationale: The correct answer is C: A ready source of glucose should be available. When managing type 1 diabetes, it is crucial to have a quick source of glucose readily available in case of hypoglycemia. This ensures that the adolescent can quickly raise their blood sugar levels to prevent complications. Choices A, B, and D are incorrect as they do not address the immediate need for glucose in managing hypoglycemia. While it is important for meals to be consumed regularly and in a controlled manner, specifying that they should be eaten at home or foods weighed using a gram scale is not as critical as ensuring a quick source of glucose in emergency situations.
