A nurse is assessing a client who has a continuous IV infusion. The nurse should identify that which of the following findings is a manifestation of fluid overload?

A. Elevated blood pressure: Excess fluid in the vascular system increases circulating volume, which raises blood pressure. This is a common early sign of fluid overload and can lead to additional complications if not addressed promptly. B. Decreased pulse rate: Fluid overload typically causes an increased pulse rate as the heart works harder to manage the extra volume. A decreased pulse is not a usual manifestation of fluid overload. C. Decreased gastrointestinal motility: Fluid overload does not directly reduce gastrointestinal motility. Bowel slowing is more commonly associated with medications, immobility, or other systemic conditions rather than excess IV fluid. D. Flattened neck veins: Fluid overload usually causes distended neck veins due to increased central venous pressure. Flattened neck veins suggest hypovolemia or low circulating blood volume rather than overload.
