A nurse is caring for a client who is receiving IV fluid therapy. For which of the following findings should the nurse monitor as an adverse effect of the IV fluid therapy?

Rationale: A. Bradycardia: Bradycardia is not a typical adverse effect of IV fluid therapy. If anything, fluid overload might contribute to hypertension or reflex tachycardia rather than a slowing of the heart rate. B. Distended neck veins: Distended neck veins are a common sign of fluid volume overload, a potential adverse effect of IV therapy. This occurs when excess fluid increases venous pressure and can indicate worsening heart function or pulmonary congestion. C. Weight loss: IV fluid therapy is expected to increase or stabilize weight due to fluid retention, not cause weight loss. Weight loss might instead indicate dehydration or catabolic states, not an adverse reaction to fluid infusion. D. Bradypnea: Bradypnea is not typically caused by IV fluid therapy. In fluid overload, the more common respiratory symptom is tachypnea or dyspnea due to pulmonary congestion, not a slowed respiratory rate.
