Hi everyone, can someone please provide a rational for this practice nclex question. I'm having trouble understanding why this is the right answer instead of D. I've always assumed that a blood culture should be initiated before an antibiotic therapy. The answer to this question is A.) The route of antibiotic therapy on the care pathway was changed from IV to PO. but I don't understand why a variance report needs to be made for a change in route.
