A nurse is collecting data from an older adult client who is receiving ondansetron IV, has a history of diabetes mellitus and cardiac myopathy, and is receiving chemotherapy to treat cancer. For which of the following adverse effects of ondansetron should the nurse monitor? (Select all that apply)

B. Dextrose 10% in water is a solution that contains a high concentration of glucose (dextrose). Infusing D10W can lead to an increase in blood glucose levels, especially if the client's body cannot metabolize the glucose effectively (e.g., in diabetic patients or those with impaired glucose tolerance).

A. Dextrose 10% in water does not contain calcium. Hypercalcemia refers to elevated calcium levels in the blood, which can occur due to various causes such as hyperparathyroidism or excessive vitamin D intake, but not from D10W infusion.

C. Dextrose 10% in water is not used to treat hypovolemia (low blood volume). It is a solution primarily used to provide calories and prevent ketosis rather than to expand circulating blood volume.

D. Dextrose 10% in water does not contain potassium. Hypokalemia (low potassium levels) can occur due to various reasons such as diuretic use, gastrointestinal losses, or inadequate intake, but it is not directly related to D10W infusion.

B. Daily weight measurements are a practical and effective method to assess fluid balance. Changes in weight can reflect fluid retention or loss. Daily weighing is particularly useful for monitoring fluid status in patients with known or suspected fluid excess. It helps detect trends over time and guides adjustments in fluid management.

A. While diagnostic tests are crucial for assessing underlying causes and complications of fluid imbalance, they do not directly provide a real-time assessment of fluid balance or volume overload.

C. Monitoring IV fluid intake provides information on the amount of fluid input but does not directly indicate how the patient's body is handling or retaining that fluid. It complements other methods like daily weight measurements.

D. Vital signs are essential for assessing the hemodynamic status and response to fluid therapy but are not specific enough to quantify fluid balance or detect mild fluid excess without other signs.
