Final answer:
The term ID refers to the intradermal route, which means putting something directly into the skin. Oral and parenteral routes (IV or IM) are suitable for home antimicrobial administration.
Step-by-step explanation:
The term ID refers to the intradermal route, meaning to put directly into the skin. Among the options provided (A. IV, B. IM, C. ID, D. SC), ID (intradermal) is the correct answer. For the administration of an antimicrobial to treat a systemic infection at home, oral and parenteral routes like intravenous (IV) or intramuscular (IM) are generally considered appropriate and convenient. Parenteral routes are particularly preferred when a drug is not effectively absorbed in the gastrointestinal tract, and higher plasma levels are required for treatment.
