Rationale Opthal
Rationale for administering Ophthalmic drops
| Question | Answer |
|---|---|
| Why do we use sterile cooton balls moistened with sterile irrigating solution or sterile noramal saline, and wipe from the inner canthus to the outer canthus prior to administering ophtalmic drops? | If not removed, material on the eyelid and lashes can be washed into the eye. Cleaning toward the outer canthus prevents contamination of the outer eye and the lacrimal duct. |
| Why do we check the ophthalmic preparation for the name, strength, and number of drops if a liquid is used? | Checking medication data is essential to prevent a medication error. |
| If ointment is used for the eye, discard the first bead, Why? | The first bead from a tube is considered to be contaminated. |
| Why would you have the patient look up while administering eye drops? | the person is less likely to blink if looking up. while the patient looks up the cornea is protected by the upper eyelid. |
| Expose the lower conjunctival sac by placing the thumb or fingers of your nondominat hand on the clients cheekbone just below the eye and gently drawing down the skin on the cheek. Why? | Placing the fingers on the cheekbone minimizes the possibility of touching the cornea, avoids putting any pressure on the eyeball, and prevents the person from blinking or squinting. |
| After administering medication, why would you instruct the paitent to close their eyelids, but do not squeeze them shut? | Closing the eye spreads the medication over the eyeball. Squeezing can injure the eye and push out the medication. |
| For liquid medications administered in the eye, press firmly or have the pt press firmly on the nasolacriaml duct for at tleast 30 seconds. Why? | Pressing on the nasolacrimal duct prevents the medication from running out of the eye and down the duct, preventing systemic absorption. |
| When exposing the lower conjunctival sac. Why would we exert pressure on the bony prominences of the cheek-bone and beneath the eyebrow when holding the eyelids? | Separating the lids prevents reflex blinking. Exerting pressure on the bony prominences minimizes the possibility of pressing the eyelid and causing discomfort. |
| Why do you hold the eye irrigator about 2.5cm (1in) above the eye? | at this height the pressure of the solution will not damage the eye tissue, and the irrigator will not touch the eye. |
| When irrigating the eye, why do you direct the solution onto the lower conjunctival sac and from the inner canthus to the lower canthus? | Directing the solution in this way prevents possible injury and prevents fluid and contaminants from flowing down the nasolacrimal duct. |
| After inserting the medication, why would you want the patient to close and move the eye periodically? | Eye closure and movement help to move secretions from the upper to the lower conjunctival sac. |
