Pediatric HESI Test Bank

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: D

Rationale: Promoting perianal skin integrity is crucial when caring for a young child with severe diarrhea to prevent skin breakdown from the irritation caused by frequent bowel movements. Maintaining the IV (Choice A) may be important for hydration but is not directly related to managing skin integrity. Taking daily weights (Choice B) is important for monitoring fluid balance but does not address the immediate need to prevent skin breakdown. While replacing lost calories (Choice C) is important, it is not the priority when a child is experiencing severe diarrhea and skin integrity is at risk.

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: Encouraging regular physical activity is crucial in managing symptoms and improving joint function in juvenile idiopathic arthritis. It helps maintain joint mobility, muscle strength, and overall well-being. Providing a high-calorie diet (Choice B) is not typically recommended unless there are specific nutritional concerns or growth issues. A low-sodium diet (Choice C) may be beneficial in conditions like hypertension, but it is not a primary focus for JIA management. Administering intravenous fluids (Choice D) is not a routine part of managing JIA unless specifically indicated for hydration or medication administration.

Correct Answer: D

Rationale: Before starting kindergarten, the child should receive boosters of DTaP, IPV, and MMR. DTaP provides protection against diphtheria, tetanus, and pertussis, IPV protects against polio, and MMR immunization covers measles, mumps, and rubella. These boosters are essential to maintain immunity and protect the child from these diseases as they enter school. Choices A, B, and C are incorrect because they do not include the recommended boosters for kindergarten entry and may leave the child susceptible to certain infections.
