What are potential risks of intravenous therapy?

Intravenous therapy, while a crucial method for administering medications and fluids directly into the bloodstream, carries certain risks that healthcare professionals must be aware of to ensure patient safety. The correct answer highlights a range of potential complications associated with intravenous therapy.

Infection is a significant concern as IV access can introduce pathogens directly into the bloodstream, leading to serious systemic infections such as sepsis. Phlebitis, which is inflammation of the vein, can occur due to mechanical irritation from the catheter or from the chemical properties of the infused fluid or medication. Extravasation refers to the leakage of intravenous fluid into the surrounding tissue, which can cause damage and, in severe cases, necrosis if caustic substances are involved. Air embolism is another serious risk that can happen if air enters the bloodstream, potentially causing a blockage in the blood vessels, leading to catastrophic outcomes. Lastly, fluid overload occurs when the volume of IV fluid administered exceeds the body's capacity to handle it, which can result in pulmonary edema or heart failure, especially in patients with preexisting conditions.
