Final answer:
The correct statement by the daughter is that she will pull down her mother's lower eyelid and drop the medication inside, which is the proper technique for administering eye drops.
Step-by-step explanation:
The statement that indicates the daughter has understood the directions for instilling eye drops in an older adult patient's right eye is "I will pull down her lower eyelid and drop the medication inside." This technique is the correct method, as it allows the eye drops to be placed into the conjunctival sac without causing injury to the eye. The patient can then close their eye gently to allow the medication to spread evenly.
Option A suggests having the mother look down, but it's more common to look up when administering eye drops. Option B, instructing the patient to tightly close the eyes, might prevent the medication from spreading evenly. Option C's thin stream medication application is not appropriate for eye drops; eye drops should be administered in drops, not in streams.
