The most important factor used to determine the rate of fluid replacement in a child after establishing the degree of dehydration should be the:

A.

hourly urine output.

B.

percentage of weight loss.

C.

clinical signs of dehydration

D.

type of dehydration, based on serum sodium concentrations.

Answer and Explanation

The Correct Answer is B

Rationale:
A. Hourly urine output helps monitor ongoing fluid status but is not the primary factor for calculating initial fluid replacement.
B. The percentage of weight loss is the most important factor for determining the degree of dehydration and the corresponding rate of fluid replacement. It provides an objective measure of fluid deficit and guides accurate rehydration.
C. Clinical signs of dehydration (e.g., dry mucous membranes, poor skin turgor) are useful for assessment but are less precise than weight loss for calculating fluid needs.
D. The type of dehydration based on serum sodium concentrations influences the composition of fluids (isotonic, hypotonic, hypertonic) rather than the overall rate of replacement.
