A 22-year-old pregnant client is diagnosed with autoimmune hemolytic anemia. The nurse anticipates immediate treatment with

  1. IgA.
  2. IgG.
  3. IgE.
  4. IgD.
Number 2 is correct.
Rationale: The client will likely require treatment with immunoglobulin G (IgG) because it is the only immunoglobulin treatment able to cross the placental barrier.
