Accepted Answer

Ointment should be applied in a thin line from the inner to the outer canthus in the conjunctival sac.

Question 8

To help reduce the nausea and vomiting experienced by a patient with Ménière's disease,the nurse would caution the patient to avoid:

Accepted Answer

Rapid movement of the head and/or eyes can increase the nausea and vomiting in a patient with Ménière's disease.

Question 11

A patient has developed keratitis.When planning care,the nurse would anticipate that the first intervention to improve the patient's comfort would be the use of:

Accepted Answer

Keratitis is an inflammation of the cornea caused by irritation or infection.Artificial tears will reduce the irritation.Antibiotics can be given in the event of a bacterial infection.Eye shields and compresses are not indicated in the management of this condition.

Question 12

The nurse notices that the patient must hold the newspaper at arm's length and squint to read.The most likely diagnosis will be:

Accepted Answer

The person with hyperopia cannot see things near at hand and must change the distance from the eyes in order to focus.The person with myopia cannot see things in the distance.Presbyopia refers to the hardening of the ciliary bodies of the eyes.Astigmatism refers to a visual defect resulting from a warped lens or an irregular curvature of the cornea.

Question 13

The nurse explains that a photorefractive keratectomy (PRK)is a very brief surgery that corrects myopia by:

Accepted Answer

A PRK uses a laser to remove a thin layer of the cornea.The LASIK procedure uses a laser to reshape the cornea and replace the outer layer.Making tiny cuts in the cornea to flatten it refers to a radial keratotomy.
