Are the Jehovah's Witnesses engaged in the practice of giving "medical advice", when they encourage you to decline any medical procedure?

Is a "Blood Transfusion" a "medical procedure", or a "spiritual procedure"?

Is the medically complicated decision to use "Blood Fractions" left up to the discretion of "lay-persons" in the congregation?

Would Jesus Christ BURDEN His people with the incredible amount of medical knowledge it takes to determine the blood fractional allowances that are offered by Jehovah's Witnesses in their brochures outlining how to "choose" what to do in the event of a "blood issue emergency"?
