34. A pharmacy technician receives a prescription that reads "2 gtt OS". This notation means the medication should be administered to the:
Answer: C
The medication should be administered to the left eye.
The notation "OS" stands for "oculus sinister," which is Latin for "left eye." Therefore, the prescription indicating "2 gtt OS" instructs the pharmacy technician to administer two drops in the left eye.
A) Left ear
This option is incorrect because the abbreviation "OS" specifically refers to the left eye, not the ear. The abbreviation for ear administration would be different, and thus this choice does not apply to the context of the prescription.
B) Right ear
This option is also incorrect. Similar to option A, the abbreviation "OS" does not pertain to the ear, and there is no mention of the right ear in the notation. The correct terminology for the right ear would be "OD" for "oculus dexter," which is not relevant here.
C) Left eye
This option is correct as the abbreviation "OS" directly translates to "left eye." The prescription clearly indicates that the medication is to be administered specifically to this part of the body.
D) Right eye
This option is incorrect because "OS" does not refer to the right eye. The correct abbreviation for the right eye is "OD," which means "oculus dexter." Therefore, this choice does not align with the prescription provided.
Conclusion
The correct answer, "left eye," is definitively supported by the medical abbreviation "OS," which distinctly indicates the left eye for administration. All other options fail to accurately represent the meaning of the given prescription notation, confirming that they are not applicable in this context.
