     A. Packed red blood cells

     B. 0.9% sodium chloride solution

     C. Lactated Ringer’s solution

     D. Fresh frozen plasma

    

    

Correct Answer: A. Packed red blood cells

In a trauma situation, the first blood product given is unmatched (O negative) packed red blood cells.

Options B and C: Lactated Ringer’s solution or 0.9% sodium chloride is used to increase volume and blood pressure, but too much of these crystalloids will dilute the blood and won’t improve oxygen-carrying capacity.

Option D: Fresh frozen plasma often is used to replace clotting factors.
