A patient with keratitis is to undergo diagnostic testing. What should the nurse anticipate being prescribed for this patient?
1. fluorescein staining with slit-lamp exam
2. photoreactive keratectomy
3. computed tomography (CT) scan
4. glycerol test
Correct Answer: 1
Keratitis is an inflammation of the cornea that results in scarring. Fluorescein stain with a slit-lamp exam allows visualization of corneal ulcerations, which is a manifestation of keratitis. Photoreactive keratectomy is a procedure using a laser to reshape the cornea and correct refractive errors. A CT scan would be indicated if a foreign body is suspected. A glycerol test is conducted to diagnosis Ménière disease.
