A nurse is collecting data from a client who has a gastrostomy tube and is experiencing diarrhea. Which of the following factors should the nurse identify as a potential cause of the diarrhea?

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.

b. "I should join a support group to help me be successful."

The statement that indicates an understanding of smoking cessation teaching is option b: "I should join a support group to help me be successful." Joining a support group is a beneficial strategy for quitting smoking as it provides social support, encouragement, and shared experiences with others who are also trying to quit.

Option a is incorrect because using nicotine patches does not allow for continued smoking as it delivers nicotine without the harmful effects of smoking.

Option c is incorrect because nicotine replacement therapy (NRT) is a safe and effective method to manage nicotine withdrawal and does not cause cancer.

Option d is incorrect because varenicline is a medication that helps reduce nicotine cravings and withdrawal symptoms, and it does not make a person addicted to nicotine.
