The nurse is assessing a client with macular degeneration. Identify the illustration that best depicts what dlients with this disorder typically see, Although all of the following measures might be useful n reducing the visual disability of a client with aduls macular degeneration (AMD), which measure should the nurse teach the client primarily as a safery precaution? 1. Wear a patch over one eye. 2. Place personal irems on the sighted side. 3. Lie in bed with the unaffected side toward the door. 4.Turn the head from side o side when walking i o ' ]

Group Assignment
1. Divide into two groups: group A and group B. The students in
group A should develop a list of potential client problems
associated with a visual deficit, and the students in group B should
prepare a similar list but addressing a hearing deficit. Within your
group, develop appropriate nursing interventions for each of the
problems you identify. Present the information to the rest of the
class and engage in a discussion with the other group of the
similarities or differences of problems and interventions.

The patient, Mrs. Elaine Markus, is a 37-year-old woman with a history of migraine headaches and visual field disturbances.
History of Present Illness
✓ Expand All
A Collapse All
Mrs. Elaine Markus is a 37-year-old woman with a history of migraine headaches and visual field disturbances. She has a left medial lower quadrant
defect lan area of reduced visual function) that was noted in December of 2014 and has been stable. She recently developed a right temporal lower
quadrant defect, which was first noted in September of 2019 and has had worsening symptoms in October.
Prior Imaging
An MRI in November showed a normal study of the brain including visual cortex and periventricular white matter, with a normal
study of the orbits, optic nerves, and extra ocular muscles. A pituitary microadenoma (small benign tumor of the pituitary gland) of
approximately 3 mm on the left side of the gland was found with…

A nurse is diagnosing an 11-year-old 6th grade studentfollowing a physical assessment. The nurse notes that the
student’s grades have dropped, she has difficulty complet-ing her work on time, and she frequently rubs her eyes
and squints. Her visual acuity on a Snellen’s eye chartis 160/20. Which nursing diagnosis would be mostappropriate?a. Deficient Knowledge related to visual impairmentb. Ineffective Role Performance (Student) related to visualimpairmentc. Disturbed Body Image related to visual impairmentd. Delayed Growth and Development related to visualimpairment

Hello,
Can you please help me with this question?
How would you have responded to engagement prompt #1 that occurred in the recorded webinar? Why?
PROMPT #1: NCLEX QUESTION
The nurse is testing the extraocular eye movements in a client with complaints of eye fatigue? The nurse would implement which assessment techniques to assess for visual abnormalities and Eye muscle weakness. Select all that apply.
Visual Acuity using the Snellen Chart
Weber Test
Cranial Nerves II, III, IV, VI
Cranial Nerve I
Refer client to ophthalmologist
Thank you in advance!

What would be the nutritional therapeutic recommendations for patients suffering from age related eye diseases, specifically age-related macular degeneration, cataract, glaucoma, and dry eye syndrome.
1. Provide nutritional health teaching to patients with these eye diseases.
2. Support your answers with a sample meal plan for each disease.

Nursing Care Plan
Knowledge deficit related to lack of information about cataract as evidenced by patient's verbalization of ignoring the symptoms of visual impairment
Short term goal- Patient will verbalize an understanding of their disease condition after 12 hours of nursing intervention
Long term goal - The patient will demonstrate adequate coping techniques to carry out activities of daily living within the liminations of visual impairment until the cataract surgery on both eyes are complete throughout hospitalization
List 20 nursing interventions with rationales for the nursing diagnosis based on the scenario
