Answer KEY
  1.  B. When teaching a patient about medications before discharge, the nurse is acting as an educator. The nurse acts as a manager when performing such activities as scheduling and making patient care assignments. The nurse performs the care giving role when providing direct care, including bathing patients and administering medications and prescribed treatments. The nurse acts as a patient advocate when making the patient’s wishes known to the doctor.
  2. A. Before cataract removal, the client will have Mydriatic drops instilled to dilate the pupil. This will facilitate removal of the lens. Miotics constrict the pupil and are not used in cataract clients. A laser is not used to smooth and reshape the lens; the diseased lens is removed.
  3. B. Typically, a patient with cataracts experiences painless, gradual loss of vision. Although both eyes may develop at different rates.
  4. B.
  5. C.
  6. A.
  7. A.
  8. A. Activities such as rigorous brushing of hair and teeth cause increased intraocular pressure and may lead to hemorrhage in the anterior chamber
  9. A.
  10. B.
  11. C. The lens allows light to pass through the pupil and focus light on the retina. The lens does not stimulate the retina, assist with eye movement, or magnify small objects, so answers A, B, and D are incorrect.
  12. D. The client should avoid straining, lifting heavy objects, and coughing harshly because these activities increase intraocular pressure. Typically, the client is instructed to avoid lifting objects weighing more than 15 lb (7kg) – not 5lb. instruct the client when lying in bed to lie on either the side or back. The client should avoid bright light by wearing sunglasses
  13. B. Typically, a patient with cataracts experiences painless, gradual loss of vision. Although both eyes may develop at different rates.
  14. C. Bending to pick up something from the floor would increase intraocular pressure, as would bending to tie his shoes. The client needs to wear eye protection to bed to prevent accidental injury during sleep.
  15. A. Presbyopia usually begins in the fifth decade of life, when reading glasses are required to magnify objects.
  16. C.
  17. C.
  18. A.
  19.  B. The eye shield should be worn at night or when napping, to prevent accidental trauma to the operative eye. Prescription eyedrops, not over-the-counter eyedrops, are ordered for the client. The client might or might not require glasses following cataract surgery. A prescription for medication to control post-operative pain will be needed is incorrect because cataract surgery is pain free.
  20.  B.
