What is the appropriate procedure for infusing fresh frozen plasma?

The procedure of infusing fresh frozen plasma (FFP) involves specific guidelines to ensure safety and effectiveness. The correct statement regarding FFP is that it must be given within 24 hours after thawing. This is crucial because FFP is made from collected plasma and contains clotting factors that can degrade over time once thawed. Proper administration is vital to maintain the integrity of these factors to prevent complications related to bleeding disorders.

The other options do not accurately represent the guidelines or best practices for FFP infusion. For instance, infusing FFP with lactated Ringer's solution is not standard practice, as it can lead to incompatibility issues. Infusing at a rate of 50 mL/hr does not reflect typical protocols; rather, FFP is typically infused over a shorter period to minimize risks and achieve therapeutic levels quickly. Lastly, while hanging FFP as a piggyback might be correct in certain contexts, caution must be exercised to avoid using potassium-containing solutions like KCl due to potential for dangerous reactions. Hence, ensuring FFP is infused within the designated time frame post-thawing is the main priority for effective treatment.
