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 B
Explanation
Answer: B. You can take a shower 1 day after your procedure.
Rationale:
A. You can resume a regular diet 3 days after your procedure:
There is typically no need to delay resuming a regular diet for three days after a cardiac catheterization. Most clients can resume their usual diet shortly after the procedure once they are fully awake and any nausea has resolved.
B. You can take a shower 1 day after your procedure:
It is generally safe to shower the day after a cardiac catheterization as long as the insertion site remains protected. Clients should avoid soaking in a bath or swimming until the site is fully healed to prevent infection.
C. You can begin exercising 2 days after your procedure:
Strenuous activities, including exercise, should generally be avoided for a few days to a week following a cardiac catheterization. This allows time for the insertion site to heal and reduces the risk of complications such as bleeding.
D. You can return to school 1 week after your procedure:
Most clients can return to school or normal activities within a few days, provided they feel well and avoid excessive physical exertion. A full week off is typically not necessary unless specified by the healthcare provider based on the individual’s recovery.
Correct Answer is B
Explanation
b. "Everyone who lives in the home will need medication."
The nurse should inform the guardian that everyone who lives in the home will need medication when reinforcing teaching about enterobiasis. Enterobiasis, also known as pinworm infection, is highly contagious, and it can easily spread from person to person within the household. Treating only the affected individual may not be sufficient to eliminate the infection completely, as other household members may also be infected or at risk of reinfection.
Explanation for the other options:
a. "One dose of medication is all that will be necessary." Enterobiasis is typically treated with a medication regimen that involves taking multiple doses over a period of time. This is to ensure that all stages of the pinworm life cycle are targeted and eradicated. A single dose is usually not sufficient to eliminate the infection completely.
c. "Allow the child to take tub baths instead of showers." The choice of tub baths or showers does not directly impact the treatment or prevention of enterobiasis. Both methods of bathing can be used, but it is important to maintain good hygiene practices, such as regular handwashing and proper cleaning of the perianal area, to reduce the risk of reinfection.
d. "Wash all clothes and bed linens in cold water." While proper hygiene practices and laundering of clothes and bed linens are important in preventing the spread of enterobiasis, using cold water alone may not be sufficient. Washing clothes and bed linens in hot water (at a temperature of at least 60°C or 140°F) is recommended to kill any pinworm eggs that may be present.
