Pediatric HESI Practice Questions

Correct Answer: A

Rationale: After a prolonged hospitalization, a toddler may exhibit excessively demanding behavior as they readjust to being home. This behavior can stem from the child feeling insecure or anxious about the changes in their environment. The child may seek extra attention and reassurance during this transition period. Choices B, C, and D are incorrect because hostility, shallowness in attachment, and withdrawal without emotional ties are less likely behaviors to be displayed by a toddler readjusting to home after a hospital stay.

Correct Answer: C

Rationale: In a child with a congenital cardiac malformation causing right-to-left shunting of blood, 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 a typical clinical finding related to right-to-left shunting. Peripheral edema (Choice B) is more commonly associated with conditions causing volume overload, such as left-sided heart failure. Absence of pedal pulses (Choice D) is not directly related to right-to-left shunting but may be seen in conditions affecting peripheral circulation.

Correct Answer: D

Rationale: The most accurate way to determine a therapeutic dose for children is based on their weight rather than age. Weight-based dosing helps ensure that the child receives the appropriate amount of medication for their body size, which is crucial for safety and effectiveness. Age-based dosing can lead to underdosing or overdosing, as children of the same age can have significantly different weights. Choice A is incorrect because even small variations in dosages can have significant effects on a child's health. Choice B is incorrect as acetaminophen can be appropriate when used correctly for fever management in children. Choice C is incorrect as children's weights can vary greatly within the same age group, making weight-based dosing more precise and individualized.

Correct Answer: A

Rationale: Encouraging parents to express their concerns is the most supportive intervention as it allows them to process their emotions and provides an opportunity for the nurse to offer appropriate support and information. This choice focuses on validating the parents' feelings and creating an open communication channel. Choices B and C are incorrect as they can hinder the parents' emotional processing and may provide false reassurance. Choice D, showing postoperative photographs, may not be appropriate at this stage as it might not address the parents' current emotional needs and could induce anxiety or unrealistic expectations.

Correct Answer: D

Rationale: The correct answer is 'D. Low-grade fever.' A low-grade fever is a common and mild side effect of the Hib vaccine, indicating that the immune system is responding to the immunization. Lethargy (choice A) can be a sign of more serious adverse effects and should be monitored closely but is not typically associated with the Hib vaccine. Urticaria (choice B) and generalized rash (choice C) are less common side effects of the Hib vaccine compared to low-grade fever.
