MSFinals-3600

A 32-year-old patient who is currently 20 weeks pregnant presents to your clinic with an itchy rash on her back and legs, which began last night. She had been in contact with her nephew who was diagnosed with shingles. She is unsure if she has had chickenpox before. Upon examination, there are red spots and blisters on her back and legs. She reports feeling well and all vital signs are normal.
What would be your next course of action?
