In cases of overload reaction, what should be administered to alleviate symptoms?

In cases of overload reaction, administering Lasix (a loop diuretic) helps alleviate symptoms by promoting diuresis, which aids in the removal of excess fluid from the body. This is particularly important in situations where there is fluid overload, leading to increased pressure in the cardiovascular system or potential pulmonary complications. Lasix works by inhibiting sodium and chloride reabsorption in the renal tubules, resulting in increased urine production, thereby reducing fluid buildup.

Other treatments, while relevant in different contexts, do not directly address the overload reaction. Fluid replacement would only exacerbate the condition by adding more volume. Lactated Ringer's is an intravenous solution that, similar to fluid replacement, would not be appropriate for managing an overload reaction and would further contribute to fluid retention. Benadryl, as an antihistamine, provides relief for allergic reactions and does not target the underlying fluid imbalance associated with overload. Thus, Lasix is the most effective choice for managing and alleviating the symptoms of an overload reaction.
