Question

which of the following signa codes denotes the timing of administration? select one: a. ac b. aa c. po d. susp clear my choice

Explanation:

To determine the correct signa code for timing of administration:

• Option a: "ac" means "ante cibum" (before meals), related to timing. But wait, let's re - check. Wait, no, actually, "po" is "per os" (by mouth, route), "susp" is for suspension (form), "aa" is "ana" (of each). Wait, no, correction: "ac" (ante cibum - before meals) is about timing of administration (when to give, before meals). But wait, maybe I made a mistake. Wait, let's recall: Signa codes for timing: "ac" (before meals), "pc" (after meals), "hs" (at bedtime) etc. But among the options:
• Option a: "ac" (ante cibum) denotes timing (before meals, when to administer).
• Option b: "aa" means "ana" (of each, used for quantities in prescriptions, not timing).
• Option c: "po" is "per os" (by mouth, route of administration, not timing).
• Option d: "susp" refers to suspension (dosage form, not timing).

Wait, maybe the initial thought was wrong. Let's re - evaluate. The question is about timing of administration. "ac" (ante cibum) is timing (when to give: before meals). So the correct option is a.

Answer:

a. ac
