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

A. Hypertension is not expected; hypotension is more typical due to decreased circulating volume. B. Bradycardia is not common; tachycardia usually occurs as a compensatory response to fluid loss. C. A weak, thready pulse is an expected finding in isotonic fluid-volume deficit because of decreased intravascular volume. D. Distended neck veins are more associated with fluid overload, not deficit.
