Question: 1 / 400

What does I-ii gtts os tid PRN indicate in a prescription?

For the ears

For the mouth

For the eyes

The prescription notation "I-ii gtts os tid PRN" signifies specific instructions for administering a medication. The "gtts" refers to drops, indicating that the dosage is given in drop form. The "os" signifies "oculus sinister," which is Latin for "left eye." Therefore, this instruction indicates that the patient should receive one to two drops in the left eye three times a day as needed (tid PRN).

The other options relate to different parts of the body but do not correspond with the meaning of "os." For example, "auris" would indicate the ear, "oral" could refer to the mouth, and "nasalis" would pertain to the nose. Given this information, the correct identification of the prescription is specifically for the left eye.
