18. A pharmacy technician should enter the abbreviation 'p.c.' as:

Answer: C

Explanation:

Entering the abbreviation 'p.c.' as after meals is correct.

The abbreviation 'p.c.' stands for 'post cibum,' which translates to 'after meals' in English. Therefore, when a pharmacy technician enters 'p.c.' in a patient's medication instructions, it indicates that the medication should be taken after meals.

A) by mouth.

This option is incorrect as 'by mouth' is typically represented by the abbreviation 'p.o.' (per os). 'p.c.' does not convey that information and specifically refers to the timing of medication relative to meals.

B) in the evening.

This choice is also incorrect. The abbreviation for 'in the evening' is 'q.h.s.' or 'hs', which does not correspond with 'p.c.'. Thus, this option does not align with the meaning of 'p.c.'.

C) after meals.

This is the correct answer since 'p.c.' directly translates to 'after meals'. When prescribing medications, it is crucial to use the correct timing to ensure the efficacy and safety of the treatment.

D) before meals.

This option is incorrect because 'before meals' is indicated by the abbreviation 'a.c.' (ante cibum). 'p.c.' specifically indicates the opposite timing, denoting that a medication should be taken after meals.

Conclusion

The correct interpretation of 'p.c.' as 'after meals' is essential in pharmacy practice to provide clear and accurate medication instructions. Other options do not represent the correct timing associated with the abbreviation, highlighting the importance of understanding medical abbreviations in patient care.
