What are some less severe complications of venipuncture?

The choice of phlebitis, clotting, and extravasation as less severe complications of venipuncture is accurate due to the nature and typical outcomes associated with these conditions compared to the other options provided.

Phlebitis is an inflammation of the vein, which can occur following venipuncture but is generally manageable with proper care and monitoring. Clotting may happen at the site of the venipuncture; while it requires attention, it typically does not result in long-term consequences if identified and managed promptly. Extravasation refers to the leakage of blood or IV fluids into surrounding tissue, which can lead to localized swelling and discomfort, but again, these effects are usually transient and resolvable without significant damage.

In contrast, the other complications listed, such as infection and hemorrhage, can lead to more severe health issues, including systemic infections or significant blood loss, making them more serious than the complications noted in your answer. Similarly, severe bruising and nerve damage can result in lasting effects or more complicated recovery, and deep vein thrombosis and gas embolism are acute and can pose significant risks to patient safety. Thus, phlebitis, clotting, and extravasation represent relatively less severe complications
