A nurse is collecting data from a client who has isotonic fluid-volume deficit. Which of the following findings should the nurse expect?

A. Weak, thready pulses are a common finding in isotonic fluid-volume deficit due to decreased circulating blood volume, which reduces cardiac output and perfusion. B. Distended neck veins are typically associated with fluid overload or hypervolemia, not fluid-volume deficit. C. Bradycardia is uncommon in fluid-volume deficit; tachycardia is more typical as a compensatory response to maintain cardiac output. D. Pitting edema occurs with fluid excess rather than deficit and indicates increased interstitial fluid.
