What is the biggest danger of phlebitis?

1. Excessive bleeding

2. Pulmonary embolism

3. Sepsis

4. Deep vein thrombosis

The correct answer is: Pulmonary embolism

The biggest danger of phlebitis is the risk of pulmonary embolism. Phlebitis refers to the inflammation of a vein, which can sometimes lead to the formation of a blood clot in the affected vein. When a clot forms, it can potentially dislodge and travel through the bloodstream to the lungs. If this occurs, it may result in a pulmonary embolism, which is a serious condition that can block blood flow in the lungs, leading to significant respiratory issues and even death. While other complications such as excessive bleeding, sepsis, and deep vein thrombosis (DVT) can occur in relation to phlebitis, the direct link to pulmonary embolism underscores its seriousness. Sepsis typically arises from an infection, while DVT refers to clotting that occurs deep within the veins, often without relationship to phlebitis directly. The emphasis on pulmonary embolism highlights the critical nature of managing phlebitis effectively to prevent severe outcomes.
