Nur 234 Final Exam Questions with
Complete Solution 2025 Update
1. When is primary prevention to maintain eye health most important?--ANS-- In the womb or
prior to pregnancy ask if they have a history of rubella or if they have received their vaccinations
2. Why is it important that a woman receives her rubella vaccination before pregnancy?--ANS-- If the
woman contracts rubella while pregnant the virus can pass through the placenta and cause congenital
diseases such as deafness and blind- ness
3. What are patient teachings regarding the rubella vaccine?--ANS-- get the vaccine before
becoming pregnant if it was not giving as a child
wait three months to get pregnant after receiving the vaccine.(because the placenta is completed at three
months and offers more protection to the fetus against any reminence of the vaccine.)
4. What is an example of prophylactic antibiotic therapy used for primary pre- vention of eye health?--
ANS--
Use of an eye prophylaxis (erythromycin) which protects the newborn baby from gonorrhea and chlamydia as
it passes through the mothers vaginal canal, this prevents blindness.
5. What is a key concept when performing general eye care?--ANS-- Always clean from inner canthus
to outer canthus to prevent dirt from being pushing into the inner canthus.
6. Way to prevent everyday eye damage ? (primary prevention)--ANS-- Limit eye strain ( allow rest
periods between reading or looking at screens)
Have UVA/UVB filters on our screen to minimize the UVA/UVB exposure When you are reading
have adequate lighting
Where sunshades with UVA/UVB protection to protect eyes when outside.(Side note--ANS--
Prolonged or excessive UVA/UVB exposure is a common cause for the development of cataracts.)
,Avoid rubbing eyes try to allow them to tear up instead
7. What is secondary prevention of eye health?--ANS-- Screening such as your annual
eye exam Snellen's--ANS-- test for visual acuity Ishihara
--ANS--test for color blindness
Tonometry --ANS-- Measures intraocular pressure ( Normal value is 12-21 mmhg)
Slit lamp exam--ANS-- use of drop slit causing the pupil to dilate to view the inner structures of the eyes
Gonnometerty--ANS-- Measurement of the angel of opening in the eye (helps determine either open or close
angle glaucoma )
Acute treatment (could be secondary or tertiary)--ANS-- Applying medications and general post operative care
8. What are some nursing considerations when treating a visually impaired patient?--ANS--
Always apply drops before ointments
Avoid increase in intraocular pressure and use and eye shield and eye patches Avoid non verbal
communication
Talk before touch, announce your presents when you enter a room
Orient the client to their new surroundings and provide a kinesthetically identifiable call bell.
Use mobility aids, stand on the imparied side
Walk slightly ahead of them, allow them to hold you but don't grab them so that they feel incontrol
Describe where you are going and your surroundings.
Describe their plates and where things are located using whatever method of direction they are most
comfortable with.
9. Nursing considerations regarding tertiary care (long term care) of a visually impaired patient?--
ANS--
Encourage the patient to train on the braille method of reading Train brail before they are fully blind if possible
Attach bells to pets to prevent falls or tripping
, 10. Nursing considerations when dealing with a visually impaired post op patient?--ANS-- Avoid any ki
of
bearing down to prevent increase intraocular pressure Utilize measure to prevent constipation such
as(Increase fluids,Ambula- tion,Fiber,PRN stool softeners)
Protective eye gear--ANS-- eye patches or eyes shield Infection
control; wash hands and dont touch eyes Report--ANS--
drainage, puss, pain pressure.
11. What is the difference between an eye shield and eye patch?--ANS-- Eye Patches are occlusive , pt
cannot see
Eyeshield if the disorder can be corrected especially when sleeping. Prevents rubbing eyes.
12. What are cataracts?--ANS-- Gradual and painless opacification of the crystalline lens of the eye
13. What are the types of cataracts?--ANS-- Congenital,senile,toxic exposure/chemical, and traumatic
14. What is a congenital cataract?--ANS-- Secondary to infectious diseases such as rubella and
measles passing through the placenta causing congenital cataracts
15. What is a senile cataract?--ANS-- Non modifible, most common and highest risk. Exposure to
heat or UVA/UVB causing opacity over time
16. What is a toxic exposure or chemical cataract--ANS-- UVA/UVB exposure,chemi- cal,or
radiation Related to work such as construction or farm workers( being outside often).
Other forms of radiation from machinery.
Chemicals from certain drugs regimens such as steroids, phenothiazines or chemotherapy drugs.
(Take baseline acuity assessment and split lamp exams to determine a baseline for chemo patients.)
17. What is a traumatic cataract?--ANS-- caused by surgery, foreign bodies, or impale- ment
causing scar tissue resulting in the opacity of the lens
18. What is another risk factor of cataracts not previously discussed?--ANS-- Uncon- trolled diabetes
