What type of fluid would you anticipate using with a patient with dehydration?
Explanation & Rationale
A. Colloid solution – Colloid solutions (e.g., albumin) are used to expand intravascular volume in cases like hypovolemic shock, not typically for general dehydration. B. Hypotonic solution – Hypotonic solutions (e.g., 0.45% NaCl) may be used after initial rehydration to shift fluid into cells, but they are not first-line for treating extracellular dehydration. C. Isotonic solution – Isotonic fluids (e.g., 0.9% normal saline or lactated Ringer’s) are the first choice for treating dehydration, especially when there is fluid volume deficit in the extracellular space. They help restore circulating volume without causing fluid shifts between compartments. D. Hypertonic solution – Hypertonic solutions draw fluid out of cells and are typically used in cases of hyponatremia or cerebral edema, not routine dehydration.
