Interpret the following medication order/Prescription sig: Insert i gtt od qhs.

The medication order specifies to "Insert i gtt od qhs," which can be broken down into its components for proper interpretation.

The term "insert" typically refers to application in a specific anatomical area, which can be relevant for medications intended for the eye. The abbreviation "i gtt" indicates "one drop," with "gtt" meaning "drops." The abbreviation "od" stands for "oculus dexter," which is Latin for "right eye." Lastly, "qhs" means "quater hora somni," or "at bedtime."

Putting this all together, the order clearly instructs the administration of one drop into the right eye at bedtime. This makes the correct interpretation align perfectly with option D, as it accurately reflects the dosage, application method, and timing specified in the prescription.

The other choices either incorrectly identify the anatomical site (right ear instead of right eye), specify the number of drops incorrectly, or mention both ears instead of focusing solely on the right eye. Understanding the specific abbreviations and directions in the prescription is critical for proper medication administration.
