Parenteral drug administration is administered or occurring elsewhere in the body than the mouth and alimentary canal.
IT IS NOT: Topical because topical means the body receives the medication via through the skin. Oral because the body receives the medication by mouth. Gas anesthesia because again the body receives the medication by mouth and upper GI through the lungs from inhalation.
The correct answer would be Intravenous injection or Intramuscular injection. These are two procedures performed to administer a parenteral medication.
