3) Oral
4) Intra-arterial
5) Rectal
6) Intrathecal

Answer 1

Parenteral administration includes intradermal, subcutaneous, intra-arterial, and intrathecal routes, bypassing the digestive system. The oral route is preferred for home administration of antimicrobials for systemic infections due to convenience.

Step-by-step explanation:

Parenteral routes of drug administration are those that are not administered orally or via the gastrointestinal tract. The following routes from the choices provided are considered parenteral: 1) Intradermal, 2) Subcutaneous, 4) Intra-arterial, and 6) Intrathecal. These methods bypass the digestive system and introduce medications directly into the body through various means.

When considering the convenience of treating a systemic infection at home, the oral route is generally preferred due to ease of administration. Conversely, parenteral routes such as intravenous administration would typically require healthcare setting due to the skill required for administration and the need for sterile conditions.
