Question 1 of 5
Which statement best describes why infants are at greater risk for dehydration than older children?
Correct Answer: B
Rationale: The correct answer is B: Infants have an increased extracellular fluid volume. Infants have a higher percentage of total body water, and a greater proportion of this water is found in the extracellular fluid compartment. This makes them more susceptible to dehydration as they have a larger volume of fluid that can be lost through various mechanisms such as vomiting, diarrhea, or fever. Option A is incorrect because infants actually have a reduced ability to concentrate urine compared to older children. Option C is incorrect as intracellular fluid volume does not directly impact dehydration risk. Option D is incorrect as body surface area is not directly related to dehydration risk in this context.
