Recall the steps for administering an eye drop in an adult and the rationale behind each step

1. Remove glasses or contact lenses to prevent damage from the drops.

2. Wash hands with soap and water to prevent contamination and potential eye infections,.

3. Obtain the medication and shake it or remove it from the refrigerator if appropriate.

4. Remove the cap without touching the dropper tip and place it on a clean surface. This prevents contamination of the bottle and avoids damaging the eye,.

5. Tilt your head back or lay down with your chin up so that the surface of your eye is parallel to the floor, which creates the best body position for drug administration,.

6. Look up as the dropper is brought toward your eye.

7. Use your fingers to gently pull down the lower eyelid to make a "pocket", creating a targeted area for the drug to be received by the eye,.

8. Place the dropper a safe distance above the eye to avoid contaminating the bottle,.

9. Gently squeeze in exactly one drop into the pocket,.

10. Gently close your eyes for 2.5 minutes (2-3 minutes) without squeezing or rubbing the eye.

11. Apply nasolacrimal obstruction (also known as punctal pressure or occlusion).

12. Wipe away any excess liquid from your face with a clean tissue,.

13. Replace and tighten the cap while avoiding touching, wiping, or rinsing the dropper tip, to prevent contamination.

Describe the simple rule of 2.5 | 5 | 10 | 20 for timing of eye medications

• 2.5 Minutes: Immediately after placing an eye drop, you should gently close your eyes for 2.5 minutes (between 2-3 minutes) without squeezing or rubbing.

• 5 Minutes: If your prescription calls for more than one drop of the same medication, wait at least 5 minutes between drops. Additionally, if you are prescribed both an eye drop and an eye ointment, always apply the drop first and wait five minutes before applying the ointment. (Applying punctal pressure is also typically held for 5 minutes).

• 10 Minutes: If you are administering more than one different medication (such as multiple distinct eye drops), wait at least 10 minutes before starting the administration of the second medication.

• 20 Minutes: Please note that the provided sources do not contain any information regarding a 20-minute rule for eye medications. If this is external knowledge required for your course, you may want to independently verify that information in your textbook. The closest relevant timing in the sources is a rule to wait at least 30 minutes before applying a second ointment.

Explain to a patient how to perform nasolacrimal occlusion when administering eye drops and why it is beneficial

• How to perform: Immediately after placing the eye drop in your eye, gently apply firm pressure with your index finger over the inner corner of your eyelids (the nasal puncta),. For an adult, you should hold this position for approximately 5 minutes.

• Why it is beneficial: Applying this pressure allows the medication to sit on the surface of the eye longer, prevents systemic absorption by stopping the medication from draining down the nose, and reduces the chance of immediate side effects from the drops,.
