Pediatric HESI Test Bank

Correct Answer: B

Rationale: The correct answer is B. Participation in contact sports like football should be avoided in children with idiopathic thrombocytopenia due to the increased risk of bleeding. Choices A, C, and D are incorrect because avoiding aspirin and drugs like ibuprofen, engaging in activities like swimming, and avoiding antihistamines are all appropriate recommendations for a child with idiopathic thrombocytopenia to prevent bleeding episodes and ensure safety.

Correct Answer: D

Rationale: The correct answer is D. Infants have a higher extracellular fluid requirement per unit of body weight, making them more susceptible to dehydration and electrolyte imbalances during illnesses such as diarrhea. Choice A is incorrect because cellular metabolism being unstable is not the primary explanation for the symptoms described. Choice B is incorrect as the proportion of water in the body alone does not fully explain the increased risk of dehydration in infants. Choice C is incorrect because while renal function is immature in children, it is not the most relevant factor in this scenario compared to the increased fluid requirements.

Correct Answer: A

Rationale: For a child with a 'slow-to-warm-up' temperament, it is important to choose activities that are less intense and allow for gradual engagement. Reading stories to the child about famous athletes would be the most successful approach as it is less active and more likely to be acceptable to the child's temperament. Choice B and C involve more active and potentially overwhelming activities, which may not suit the child's temperament. Choice D, proposing wrestling and letting the child win, might create a competitive environment that could be counterproductive for a 'slow-to-warm-up' child.

Correct Answer: A

Rationale: Abdominal swelling is a classic presentation and often the first noticeable sign of a Wilms tumor. This occurs due to the tumor mass in the kidney, leading to abdominal distension. Weight gain (Choice B) is less likely as a presenting symptom compared to abdominal swelling. Hypotension (Choice C) is not typically associated with a Wilms tumor unless complications like bleeding or shock occur. Increased urinary output (Choice D) is not a typical finding for Wilms tumor; instead, patients may present with hematuria or urinary symptoms.

Correct Answer: C

Rationale: Discussing any other observed behaviors can help identify patterns or potential issues, which is crucial for assessing the infant's overall well-being. Option A about accidents and prevention is not pertinent to the situation described. Option B regarding playtime with other children does not address the infant's behavior and potential causes. Option D about food and vitamins is not relevant to the presented scenario and the observed behavior of the infant.
