Which finding would indicate hypovolemia in a postpartum client?

• A. Warm, dry skin
• B. Decreased thirst
• C. Rapid, weak pulse
• D. Normal blood pressure

Answer: (C)

Hypovolemia means there is less blood effectively circulating, so the heart tries to compensate by beating faster, but the force of each beat diminishes. A rapid, weak pulse is the clearest reflection of this reduced volume and decreased preload; it often appears early in postpartum hemorrhage as the body attempts to maintain perfusion to vital organs. In contrast, skin that is warm and dry doesn’t fit hypovolemia caused by blood loss—the typical response is cool, clammy skin from peripheral vasoconstriction. Decreased thirst isn’t a reliable early sign of reduced circulating volume, and normal blood pressure can occur with early compensation, so it doesn’t signal hypovolemia by itself.
