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?

A. Distended neck veins: Distended neck veins can indicate fluid volume overload, which is a potential adverse effect of IV fluid therapy. Monitoring for jugular vein distention helps detect early signs of circulatory overload and prevents complications such as pulmonary edema. B. Bradycardia: Bradycardia is not commonly associated with IV fluid therapy. In fact, fluid overload or dehydration typically affects blood pressure and heart rate differently, often causing tachycardia rather than a slow heart rate. C. Bradypnea: Slowed respiratory rate is not a direct adverse effect of IV fluid therapy. Respiratory changes are more likely to result from severe fluid overload leading to pulmonary edema, but bradypnea specifically is uncommon in this context. D. Weight loss: Weight loss is not an expected adverse effect of IV fluid therapy. IV fluids generally increase intravascular volume, so clients receiving therapy are more likely to gain weight if fluid retention occurs.
