What complication can arise from administering large volumes of IV fluids?

Administering large volumes of IV fluids can lead to significant complications like electrolyte imbalances and volume overload. When excess fluid is introduced into the body, it can dilute essential electrolytes, resulting in conditions such as hyponatremia (low sodium) or hyperkalemia (high potassium). This imbalance can disrupt normal cellular function and lead to various health issues, including muscle weakness, arrhythmias, or seizures.

Volume overload occurs when the body's fluid capacity is exceeded, potentially leading to pulmonary edema, in which fluid accumulates in the lungs. This can cause difficulty in breathing, increased heart workload, and in severe cases, cardiovascular failure. Monitoring fluid intake and output, as well as regularly assessing the patient's vital signs and lab values, is vital to prevent these complications during IV fluid therapy.
