A nurse is planning to administer an ophthalmic medication to a client. Which of the following actions will
minimize systemic absorption of the medication?
Apply light pressure to the inner canthus just after instilling the eye drops
Wipe the eye from the inner to the outer canthus with a sterile saline-moistened coton ball
Administer the medication drops directly into the lower conjunctival sac of each eye
Wait 5 min after instillation before instilling the drops in the other eye
None
None
The Correct Answer is A
Answer: A. Apply light pressure to the inner canthus just after instilling the eye drops.
Rationale:
A) Apply light pressure to the inner canthus just after instilling the eye drops.
Applying pressure to the inner canthus (the corner of the eye nearest the nose) helps occlude the nasolacrimal duct. This action reduces the systemic absorption of the medication by preventing it from draining into the nasal passages and subsequently into the systemic circulation, thus enhancing the local effect of the eye drops.
B) Wipe the eye from the inner to the outer canthus with a sterile saline-moistened cotton ball.
While this action may help remove excess medication or discharge, it does not minimize systemic absorption. Instead, wiping the eye could inadvertently spread the medication to other areas, increasing the chance of absorption rather than reducing it.
C) Administer the medication drops directly into the lower conjunctival sac of each eye.
While placing drops in the lower conjunctival sac is a standard practice for delivering ophthalmic medications, it does not directly influence systemic absorption. The main goal is to ensure adequate dosing in the eye, but systemic absorption can still occur if the drops drain into the nasolacrimal duct.
D) Wait 5 min after instillation before instilling the drops in the other eye.
Waiting between instillations is good practice to prevent dilution of the first dose and to allow for absorption. However, this action does not significantly impact systemic absorption. It focuses more on ensuring that the first dose is effective before administering a second dose.

Correct Answer is A
Explanation
The first action the nurse should plan to perform is to check the client's ability to use the call light. This is essential to ensure that the client can easily communicate with the healthcare team if they need assistance or experience a fall risk situation. By confirming the client's ability to use the call light, the nurse can address any potential communication barriers and ensure that the client has a means to request help promptly.
Explanation for the other options:
b) Document the client's risk in the medical record: While documenting the client's risk in the medical record is important, it is not the first action to be taken. Ensuring the client's immediate safety and ability to request assistance is the priority.
c) Request a referral for physical therapy: Referring the client for physical therapy may be a necessary step to address their impaired mobility and reduce fall risk, but it is not the first action to be performed. Assessing their ability to use the call light takes precedence in order to address immediate safety concerns.
d) Place a gait belt in the client's room: Providing a gait belt is a measure to assist with mobility and falls prevention. However, it should not be the first action. Checking the client's ability to use the call light is more critical to ensure their immediate safety and ability to request help.
