EENT and Sleep Disorders Q 52

Mang Isko, a 68-year-old widower, has been stricken with cataracts about a year ago. Which assessment data would the nurse expect when collecting the nursing history from the client?
     A. Blurred vision
     B. Eye pain
     C. Floaters
     D. Eye redness

Correct Answer: A. Blurred vision

Cataracts lead to progressive worsening and blurring of vision. A cataract is a disease of the eye in which the normally clear lens has opacified which obscures the passage of light. It is a gradually progressive disease and a significant cause of blindness around the world. The decrease or blurring in the vision is gradual and painless; unilateral or bilateral depending upon the eye being affected without and at mature stages even with glasses

Option B: Eye pain, common with glaucoma, is not present with cataracts. Typically, attacks are precipitated by pupillary dilation due to weak mydriatic, or dilating, drops. Intraocular pressure will typically be high and often in the 30-50 mm Hg range.
Option C: Floaters are characteristics of retinal detachment. Retinal detachments constitute a serious ocular condition and can lead to permanent vision loss. When the retina, the neurosensory layer, detaches from the back of the eye, it loses its oxygen and nutrient supply leading to the death of the tissue.
Option D: In the acute angle-closure type, patients typically present with severe sudden ocular pain, redness, blurry vision/decreased visual acuity, headache, nausea or vomiting, and may complain of seeing halos of light. Patients will have an unresponsive mid-dilated pupil on examination and a firm feeling eyeball on palpation.
