  1. It blocks the responses that are sent to the eye muscles.
  2. It will relax the eye muscles and decrease blurring of vision.
  3. It will constrict the eye to reduce intraocular pressure.
  4. It will dilate the eye to reduce intraocular pressure.

6. A client went to a health care facility with a complaint of difficulty opening the eyelid because of pain. The physician diagnosed the client with keratitis and is prescribed with an eye lubricant. Which of the following medicine should the nurse expect to administer?

  1. Hydroxypropyl methylcellulose (Lacril).
  2. Pilocarpine hydrochloride (Isopto Carpine).
  3. Timolol maleate (Timoptic).
  4. Apraclonidine (Lopidine).

  1. Metipranolol (Optipranolol).
  2. Brimonidine (Alphagan P).
  3. Dorzolamide (Trusopt).

  3. Warm the irrigating solution to 98º Fahrenheit.
  4. Directs a slow steady current of irrigating solution into the eardrum.

  1. Amoxicillin (Amoxil).
  2. Carvedilol (Coreg).
  3. Atropine sulfate (Isopto Atropine).
  4. Aspirin (Ecotrin).

10. A nurse is providing instructions to a client with an impacted cerumen who is prescribed with Carbamide peroxide (Debrox). Which of the following teachings made by the nurse indicates a further research?

  1. Do not touch the dropper tip or let it touch your ear or any other surface.
  2. Lie on your side or tilt the affected ear upward. Hold the dropper directly over the ear and place 5 to 10 drops into the ear canal.
  3. Hold the earlobe up and back.
  4. Use a cold preparation of the medication.
Answers and Rationale:

1. Answer: B. Apply gentle pressure with a clean tissue to the nasolacrimal duct for 30 seconds after the administration. Occluding the nasolacrimal duct with a tissue over the inner canthus for 30-60 seconds will minimize the systemic absorption of the medication.

  • Option A: Allowing the tip to be touch with the conjunctival sac will contaminate the medication.
  • Option C will prevent the maximum absorption of the medication.
  • Option D is not related to the administration of the optic drops.

2. Answer: B. Administer the eye drop first, followed by the eye ointment. If both an eye drop and eye ointment are scheduled at the same time, administer the eye drop first; separate the installation by 3-5 minutes.

3. Answer: A. Dilate the pupil of the operative eye. Cyclopentolate is a mydriatic and cycloplegic medication that works by temporarily widening (dilating) the pupil of the eye and relaxing the muscles of the eye.

4 Answer: D. Monitor pulse rate. Betaxolol hydrochloride is a beta-adrenergic blocker eye medication. The nurse should monitor the blood pressure and pulse rate for signs of hypotension and bradycardia.

5. Answer: C. It will constrict the eye to reduce intraocular pressure. Miotics causes pupillary constrictions and are used to treat glaucoma. These medications reduce eye pressure by increasing the drainage of intraocular fluid through the trabecular meshwork.

  • Options A, B, and D are related to mydriatic medications.

6. Answer: A. Hydroxypropyl methylcellulose (Lacril). Hydroxypropyl methylcellulose (Lacril) is an eye lubricant.

  • Option B is a miotic.
  • Option C is a β-adrenergic blocking eye medication.
  • Option D is a α-adrenergic agonist.

7. Answer: D. Atropine (Isopto Atropine). Atropine (Isopto Atropine) is a mydriatic and is contraindicated with glaucoma because of the risk of increased ocular pressure.

  • Options A, B, and C are used to treat glaucoma.

8. Answer: C. Warm the irrigating solution to 98º Fahrenheit. Warm the irrigating solution to 98ºF because a solution temperature that is not close the client’s body temperature will cause ear injury, vertigo, and nausea.

  • Option A is not correct because the client is to lie on the affected side to complete draining the irrigating solution.
  • Option B is applied only to children 3 years younger.
  • Option D will cause a damage to the eardrum.

9. Answer: D. Aspirin (Ecotrin). Aspirin (Ecotrin) is potentially ototoxic. The prescribing physician should be notified that the condition and the prescribed drug can be evaluated.

  • Options A, B, and C are not associated with hearing problems.

10. Answer: D. Use a cold preparation of the medication. Carbamide peroxide is a cerumenolytic medication. Using cold ear drops can cause dizziness in order to avoid it, hold the container in your hand for a few minutes to warm it.
