RBC infusion is not done with:

**Core Concept**
RBC (Red Blood Cell) infusion is a medical procedure used to treat anemia or severe blood loss. The choice of transfusion fluid depends on various factors, including the patient's hemodynamic status, blood type, and the presence of any underlying medical conditions.

**Why the Correct Answer is Right**
The correct choice of transfusion fluid is crucial to prevent adverse reactions, such as hemolysis or transfusion-related acute lung injury (TRALI). ABO blood group compatibility is essential, and Rh(D) typing is also considered when transfusing blood to a pregnant woman or a patient with a history of hemolytic disease of the newborn. RBC units are usually stored at 2-6°C to maintain their viability and function.

**Why Each Wrong Option is Incorrect**
**Option A:** Not typically done with Dextran solutions, as they can cause hemodilution and anaphylactoid reactions.
**Option B:** Not typically done with Hypertonic saline, as it can cause hemolysis and renal failure.
**Option C:** Not typically done with Lactated Ringer's solution, as it can cause hemodilution and acid-base imbalance, but it does have a place in resuscitation.

**Clinical Pearl / High-Yield Fact**
When administering RBC transfusions, it is essential to remember that the patient's hemoglobin level should be carefully monitored, and the transfusion should be titrated to avoid over-transfusion or under-transfusion.

**Correct Answer:** C.
