The client is being discharged from the ambulatory care unit following cataract removal.
The nurse provides instructions regarding home care.
Which of the following, if stated by the client, indicates an understanding of the instructions?

I will sleep on the operative side for two weeks.

I will not lift anything more than 30 pounds (13.6 kg).

I will wear an eye shield at night and glasses during the day.

I will avoid using eye drops for the first week.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Sleeping on the operative side increases pressure on the eye, risking complications like increased intraocular pressure and disrupted healing of surgical incisions. Postoperative care avoids this positioning.

Choice B rationale

Lifting items over 5-10 pounds risks increased intraocular pressure. Guidelines usually limit lifting to light objects, not 30 pounds. Heavy lifting can cause strain affecting surgical recovery.

Choice C rationale

Eye shields protect the operative site during sleep, preventing accidental trauma, while glasses shield from debris during daytime. These preventive measures support proper healing and recovery post-cataract surgery.

Choice D rationale

Avoiding eye drops disrupts healing as prescribed medications manage inflammation and prevent infections after surgery. Proper use of eye drops supports post-surgical recovery effectively.

Correct Answer is B

Explanation

Choice A rationale

Symmetry of extraocular movements assesses cranial nerve function but does not relate to the corrective purpose of bifocals, which is addressing near and distant vision issues caused by presbyopia and myopia.

Choice B rationale

Bifocals correct presbyopia and myopia by combining lenses for near and distant vision in one frame. Effectiveness is assessed by evaluating improvements in both visual ranges, ensuring accommodation and refraction are properly corrected.

Choice C rationale

Cloudiness in the lens indicates cataracts, which bifocals cannot correct. Cataracts require surgical intervention, making this assessment irrelevant to determining bifocal lens effectiveness for presbyopia and myopia.

Choice D rationale

Intraocular pressure changes relate to glaucoma, not refractive issues like myopia or presbyopia. Monitoring for glaucoma requires tonometry, independent of bifocal lens evaluation.

Correct Answer is ["0.1"]
