Pediatric HESI 2023 Questions
Question 1 of 5
A 2-week-old infant is admitted with a tentative diagnosis of a ventricular septal defect. The parents report that their baby has had difficulty feeding since coming home after birth. What should the nurse consider before responding?
Correct Answer: C
Rationale: Ineffective sucking and swallowing can be early signs of a heart defect like a ventricular septal defect. This is crucial information for the nurse to consider as it aligns with the infant's tentative diagnosis. Choice A is too general and does not provide specific relevance to the situation. Choice B is incorrect as inadequate sucking can indeed be significant, especially in the context of a potential heart defect. Choice D is not directly related to the potential heart defect and feeding difficulties mentioned in the scenario.
Question 2 of 5
The parents of an infant ask the nurse why their baby is scheduled to receive the intramuscular polio vaccine rather than the oral vaccine. What is the nurse's best response?
Correct Answer: A
Rationale: The American Academy of Pediatrics recommends the intramuscular polio vaccine because it has a better safety profile compared to the oral vaccine. Choice B is incorrect because the AAP specifically recommends the intramuscular vaccine over the oral vaccine. Choice C is incorrect as cost is not the primary reason for preferring the intramuscular vaccine. Choice D is incorrect as the recommendation is based on safety rather than the immunocompromised status of the infant or family members.
Question 3 of 5
The nurse is developing a plan of care for a 7-year-old boy with diabetes insipidus. What is the priority nursing diagnosis?
Correct Answer: A
Rationale: The priority nursing diagnosis for a 7-year-old boy with diabetes insipidus is deficient fluid volume related to dehydration. Diabetes insipidus causes excessive thirst and urination, leading to fluid imbalance and potential dehydration. Choice B, excess fluid volume related to edema, is not a priority as diabetes insipidus is characterized by fluid loss, not retention. Choice C, deficient knowledge related to fluid intake regimen, may be important but is not the priority when the child is at risk of dehydration. Choice D, imbalanced nutrition related to excess weight, is not directly associated with the primary concern of fluid volume imbalance in diabetes insipidus.
Question 4 of 5
The nurse is reviewing the laboratory test results of a child with Addison's disease. What would the nurse expect to find?
Correct Answer: B
Rationale: In Addison's disease, adrenal insufficiency leads to decreased aldosterone production. This results in impaired sodium retention and potassium excretion, leading to hyperkalemia. Therefore, the correct answer is hyperkalemia (choice B). Hypernatremia (choice A) is less likely because of the loss of sodium in Addison's disease. Hyperglycemia (choice C) and hypercalcemia (choice D) are not typically associated with Addison's disease and are less likely to be present in this condition.
Question 5 of 5
When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:
Correct Answer: A
Rationale: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.
