At the end of an in-chamber IV treatment, adding a small amount of fluid to the drip chamber is important for several reasons. This practice ensures that there is no opportunity for the formation of air bubbles in the line, which can be especially critical in hyperbaric treatments. Air bubbles can lead to complications, such as air embolism, which can be dangerous in a hyperbaric environment. By adding fluid, you help ensure the line remains filled with solution, minimizing the risk of air entering the line after the treatment.

Moreover, keeping the drip chamber filled with fluid helps maintain a clear view of the fluid levels, making it easier to monitor the infusion process during future treatments. This proactive measure is important for patient safety and effective treatment continuity.

In contrast, other actions, such as adding a large amount of fluid to the IV or disconnecting the IV line immediately, may not be advisable in this scenario. Adding excessive fluid could lead to complications like fluid overload. Disconnecting the IV line too soon could also introduce air into the line or disrupt the ongoing treatment process. Ensuring there is no air in the drip chamber does not address the need to keep the line filled and prepared for any future infusions. Hence, adding a small amount of
