Question 78

The prescription notation "ac" means before meals.

The notation "ac" is an abbreviation derived from Latin, specifically "ante cibum," which translates to "before meals." This indicates that the medication should be taken prior to eating.

A) before meals.

This option is correct as "ac" specifically denotes that the medication should be administered before meals, aligning perfectly with the definition of the abbreviation.

B) each ear.

This option is incorrect because "each ear" is typically denoted by "AU" (auris utraque) in medical terminology, not "ac." Hence, it does not relate to the meaning of "ac."

C) after meals.

This option is incorrect because "after meals" is represented by the abbreviation "pc" (post cibum), which is the opposite of "ac." Therefore, it does not accurately reflect the meaning of "ac."

D) right eye.

This option is incorrect as "right eye" is indicated by the abbreviation "OD" (oculus dexter). It has no connection with the meaning of "ac," which specifically refers to timing in relation to meals.

Conclusion

In summary, the abbreviation "ac" unequivocally signifies "before meals," making option A the definitive correct answer. All other options misinterpret the meaning of the abbreviation, as they refer to different contexts within medical terminology.
