761. The nurse is preparing to administer eye drops. Which interventions should the nurse take to administer the drops? Select all that apply. 1. Wash hands. 2. Put gloves on. 3. Place the drop in the conjunctival sac. 4. Pull the lower lid down against the cheekbone. 5. Instruct the client to squeeze the eyes shut after instilling the eye drop. 6. Instruct the client to tilt the head forward, open the eyes, and look down.

1, 2, 3, 4 Rationale: To administer eye medications, the nurse should wash hands and put gloves on. The client is instructed to tilt the head backward, open the eyes, and look up. The nurse pulls the lower lid down against the cheekbone and holds the bottle like a pencil with the tip downward. Holding the bottle, the nurse gently rests the wrist of the hand on the client's cheek and squeezes the bottle gently to allow the drop to fall into the conjunctival sac. The client is instructed to close the eyes gently and not to squeeze the eyes shut to prevent the loss of medication.

752. The nurse is preparing a teaching plan for a client who had a cataract extraction with intraocular implantation. Which home care measures should the nurse include in the plan? Select all that apply. 1. Avoid activities that require bending over. 2. Contact the surgeon if eye scratchiness occurs. 3. Take acetaminophen for minor eye discomfort. 4. Expect episodes of sudden severe pain in the eye. 5. Place an eye shield on the surgical eye at bedtime. 6. Contact the surgeon if a decrease in visual acuity occurs.

1, 3, 5, 6. Rationale: Following eye surgery, some scratchiness and mild eye discomfort may occur in the operative eye and usually is relieved by mild analgesics. If the eye pain becomes severe, the client should notify the surgeon because this may indicate hemorrhage, infection, or increased intraocular pressure (IOP). The nurse also would instruct the client to notify the surgeon of increased purulent drainage, increased redness, or any decrease in visual acuity. The client is instructed to place an eye shield over the operative eye at bedtime to protect the eye from injury during sleep and to avoid activities that increase IOP, such as bending over.

762. The nurse prepares a client for ear irrigation as prescribed by the health care provider. Which action should the nurse take when performing the procedure? 1. Warm the irrigating solution to 98.6 °F (37.0 °C). 2. Position the client with the affected side up following the irrigation. 3. Direct a slow, steady stream of irrigation solution toward the eardrum. 4. Assist the client to turn his or her head so that the ear to be irrigated is facing upward.

1. Rationale: Before ear irrigation, the nurse should inspect the tympanic membrane to ensure that it is intact. The irrigating solution should be warmed to 98.6 °F (37.0 °C) because a solution temperature that is not close to the client's body temperature will cause ear injury, nausea, and vertigo. The affected side should be down following the irrigation to assist in drainage of the fluid. When irrigating, a direct and slow steady stream of irrigation solution is directed toward the wall of the canal, not toward the eardrum. The client is positioned sitting, facing forward with the head in a natural position; if the ear is faced upward, the nurse would not be able to visualize the canal.

751. A woman was working in her garden. She accidentally sprayed insecticide into her right eye. She calls the emergency department, frantic and screaming for help. The nurse should instruct the woman to take which immediate action? 1. Irrigate the eyes with water. 2. Come to the emergency department. 3. Call the health care provider (HCP). 4. Irrigate the eyes with diluted hydrogen peroxide.

1. Rationale: In this type of accident, the client is instructed to irrigate the eyes immediately with running water for at least 20 minutes, or until the emergency medical services personnel arrive. In the emergency department, the cleansing agent of choice is usually normal saline. Calling the HCP and going to the emergency department delays necessary intervention. Hydrogen peroxide is never placed in the eyes.

741. During the early postoperative period, a client who has undergone a cataract extraction complains of nausea and severe eye pain over the operative site. What should be the initial nursing action? 1. Call the health care provider (HCP). 2. Reassure the client that this is normal. 3. Turn the client onto his or her operative side. 4. Administer the prescribed pain medication and antiemetic.

1. Rationale: Severe pain or pain accompanied by nausea following a cataract extraction is an indicator of increased intraocular pressure and should be reported to the HCP immediately. Options 2, 3, and 4 are inappropriate actions.

748. The client sustains a contusion of the eyeball following a traumatic injury with a blunt object. Which intervention should be initiated immediately? 1. Apply ice to the affected eye. 2. Irrigate the eye with cool water. 3. Notify the health care provider (HCP). 4. Accompany the client to the emergency department.

1. Rationale: Treatment for a contusion begins at the time of injury. Ice is applied immediately. The client then should be seen by an HCP and receive a thorough eye examination to rule out the presence of other eye injuries.

757. The nurse is preparing to test the visual acuity of a client, using a Snellen chart. Which identifies the accurate procedure for this visual acuity test? 1. The right eye is tested, followed by the left eye, and then both eyes are tested. 2. Both eyes are assessed together, followed by an assessment of the right eye and then the left eye. 3. The client is asked to stand at a distance of 40 feet (12 meters) from the chart and to read the largest line on the chart. 4. The client is asked to stand at a distance of 40 feet (12 meters) from the chart and to read the line that can be read 200 feet (60 meters) away by an individual with unimpaired vision.

1. Rationale: Visual acuity is assessed in 1 eye at a time, and then in both eyes together, with the client comfortably standing or sitting. The right eye is tested with the left eye covered; then the left eye is tested with the right eye covered. Both eyes are then tested together. Visual acuity is measured with or without corrective lenses and the client stands at a distance of 20 feet (6 meters) from the chart.

764. A client is prescribed an eye drop and an eye ointment for the right eye. How should the nurse best administer the medications? 1. Administer the eye drop first, followed by the eye ointment. 2. Administer the eye ointment first, followed by the eye drop. 3. Administer the eye drop, wait 15 minutes, and administer the eye ointment. 4. Administer the eye ointment, wait 15 minutes, and administer the eye drop.

1. Rationale: When an eye drop and an eye ointment are scheduled to be administered at the same time, the eye drop is administered first. The instillation of two medications is separated by 3 to 5 minutes.

749. A client arrives in the emergency department with a penetrating eye injury from wood chips that occurred while cutting wood. The nurse assesses the eye and notes a piece of wood protruding from the eye. What is the initial nursing action? 1. Apply an eye patch. 2. Perform visual acuity tests. 3. Irrigate the eye with sterile saline. 4. Remove the piece of wood using a sterile eye clamp.

2. Rationale: If the eye injury is the result of a penetrating object, the object may be noted protruding from the eye. This object must never be removed except by the ophthalmologist because it may be holding ocular structures in place. Application of an eye patch or irrigation of the eye may disrupt the foreign body and cause further tearing of the cornea.

753. Tonometry is performed on a client with a suspected diagnosis of glaucoma. The nurse looks at the documented test results and notes an intraocular pressure (IOP) value of 23. What should be the nurse's initial action? 1. Apply normal saline drops. 2. Note the time of day the test was done. 3. Contact the health care provider (HCP). 4. Instruct the client to sleep with the head of the bed flat.

2. Rationale: Tonometry is a method of measuring intraocular fluid pressure. Pressures between 10 and 21 mm Hg are considered within the normal range. However, IOP is slightly higher in the morning. Therefore, the initial action is to check the time the test was performed. Normal saline drops are not a specific treatment for glaucoma. It is not necessary to contact the HCP as an initial action. Flat positions may increase the pressure.

747. A client arrives in the emergency department following an automobile crash. The client's forehead hit the steering wheel and a hyphema is diagnosed. The nurse should place the client in which position? 1. Flat in bed 2. A semi-Fowler's position 3. Lateral on the affected side 4. Lateral on the unaffected side

2. Rationale: A hyphema is the presence of blood in the anterior chamber. Hyphema is produced when a force is sufficient to break the integrity of the blood vessels in the eye and can be caused by direct injury, such as a penetrating injury from a BB or pellet, or indirectly, such as from striking the forehead on a steering wheel during an accident. The client is treated by bed rest in a semi-Fowler's position to assist gravity in keeping the hyphema away from the optical center of the cornea.

756. A client with Meniere's disease is experiencing severe vertigo. Which instruction should the nurse give to the client to assist in controlling the vertigo? 1. Increase sodium in the diet. 2. Avoid sudden head movements. 3. Lie still and watch the television. 4. Increase fluid intake to 3000 mL a day.

2. Rationale: The nurse instructs the client to make slow head movements to prevent worsening of the vertigo. Dietary changes such as salt and fluid restrictions that reduce the amount of endolymphatic fluid are sometimes prescribed. Lying still and watching television will not control vertigo.

745. A client is diagnosed with a disorder involving the inner ear. Which is the most common client complaint associated with a disorder involving this part of the ear? 1. Pruritus 2. Tinnitus 3. Hearing loss 4. Burning in the ear

2. Rationale: Tinnitus is the most common complaint of clients with otological disorders, especially disorders involving the inner ear. Symptoms of tinnitus range from mild ringing in the ear, which can go unnoticed during the day, to a loud roaring in the ear, which can interfere with the client's thinking process and attention span. Options 1, 3, and 4 are not associated specifically with disorders of the inner ear.

758. A client's vision is tested with a Snellen chart. The results of the tests are documented as 20/60. What action should the nurse implement based on this finding? 1. Provide the client with materials on legal blindness. 2. Instruct the client that he or she may need glasses when driving. 3. Inform the client of where he or she can purchase a white cane with a red tip. 4. Inform the client that it is best to sit near the back of the room when attending lectures.

2. Rationale: Vision that is 20/20 is normal—that is, the client is able to read from 20 feet (6 meters) what a person with normal vision can read from 20 feet (6 meters). A client with a visual acuity of 20/60 can only read at a distance of 20 feet (6 meters) what a person with normal vision can read at 60 feet (18 meters). With this vision, the client may need glasses while driving in order to read signs and to see far ahead. The client should be instructed to sit in the front of the room for lectures to aid in visualization. This is not considered to be legal blindness.

759. The nurse is caring for a hearing-impaired client. Which approach will facilitate communication? 1. Speak loudly. 2. Speak frequently. 3. Speak at a normal volume. 4. Speak directly into the impaired ear.

3. Rationale: Speaking in a normal tone to the client with impaired hearing and not shouting are important. The nurse should talk directly to the client while facing the client and speak clearly. If the client does not seem to understand what is said, the nurse should express it differently. Moving closer to the client and toward the better ear may facilitate communication, but the nurse should avoid talking directly into the impaired ear.

755. The nurse notes that the health care provider has documented a diagnosis of presbycusis on a client's chart. Based on this information, what action should the nurse take? 1. Speak loudly, but mumble or slur the words. 2. Speak loudly and clearly while facing the client. 3. Speak at normal tone and pitch, slowly and clearly. 4. Speak loudly and directly into the client's affected ear.

3. Rationale: Presbycusis is a type of hearing loss that occurs with aging. Presbycusis is a gradual sensorineural loss caused by nerve degeneration in the inner ear or auditory nerve. When communicating with a client with this condition, the nurse should speak at a normal tone and pitch, slowly and clearly. It is not appropriate to speak loudly, mumble or slur words, or speak into the client's affected ear.

767. A client was just admitted to the hospital to rule out a gastrointestinal (GI) bleed. The client has brought several bottles of medications prescribed by different specialists. During the admission assessment, the client states, "Lately, I have been hearing some roaring sounds in my ears, especially when I am alone." Which medication would the nurse identify as the cause of the client's complaint? 1. Doxycycline 2. Atropine sulfate 3. Acetylsalicylic acid 4. Diltiazem hydrochloride

3. Rationale: Aspirin is contraindicated for GI bleeding and is potentially ototoxic. The client should be advised to notify the prescribing health care provider so the medication can be discontinued and/or a substitute that is less toxic to the ear can be taken instead. Options 1, 2, and 4 do not have effects that are potentially associated with hearing difficulties.

768. In preparation for cataract surgery, the nurse is to administer cyclopentolate eye drops at 0900 for surgery that is scheduled for 0915. What initial action should the nurse take in relation to the characteristics of the medication action? 1. Provide lubrication to the operative eye prior to giving the eye drops. 2. Call the surgeon, as this medication will further constrict the operative pupil. 3. Consult the surgeon, as there is not sufficient time for the dilative effects to occur. 4. Give the medication as prescribed; the surgeon needs optimal constriction of the pupil.

3. Rationale: Cyclopentolate is a rapidly acting mydriatic and cycloplegic medication. Cyclopentolate is effective in 25 to 75 minutes, and accommodation returns in 6 to 24 hours. Cyclopentolate is used for preoperative mydriasis, not pupil constriction. The nurse should consult with the surgeon about the time of administration of the eye drops since 15 minutes is not adequate time for dilation to occur.

760. Betaxolol hydrochloride eye drops have been prescribed for a client with glaucoma. Which nursing action is most appropriate related to monitoring for side and adverse effects of this medication? 1. Assessing for edema 2. Monitoring temperature 3. Monitoring blood pressure 4. Assessing blood glucose level

3. Rationale: Hypotension, dizziness, nausea, diaphoresis, headache, fatigue, constipation, and diarrhea are side and adverse effects of the medication. Nursing interventions include monitoring the blood pressure for hypotension and assessing the pulse for strength, weakness, irregular rate, and bradycardia. Options 1, 2, and 4 are not specifically associated with this medication.

750. The nurse is caring for a client following enucleation and notes the presence of bright red drainage on the dressing. Which action should the nurse take at this time? 1. Document the finding. 2. Continue to monitor the drainage. 3. Notify the health care provider (HCP). 4. Mark the drainage on the dressing and monitor for any increase in bleeding.

3. Rationale: If the nurse notes the presence of bright red drainage on the dressing, it must be reported to the HCP, because this indicates hemorrhage. Options 1, 2, and 4 are inappropriate at this time.

766. A miotic medication has been prescribed for the client with glaucoma and the client asks the nurse about the purpose of the medication. Which response should the nurse provide to the client? 1. "The medication will help dilate the eye to prevent pressure from occurring." 2. "The medication will relax the muscles of the eyes and prevent blurred vision." 3. "The medication causes the pupil to constrict and will lower the pressure in the eye." 4. "The medication will help block the responses that are sent to the muscles in the eye."

3. Rationale: Miotics cause pupillary constriction and are used to treat glaucoma. They lower the intraocular pressure, thereby increasing blood flow to the retina and decreasing retinal damage and loss of vision. Miotics cause a contraction of the ciliary muscle and a widening of the trabecular meshwork. Options 1, 2, and 4 are incorrect.

742. The nurse is developing a teaching plan for a client with glaucoma. Which instruction should the nurse include in the plan of care? 1. Avoid overuse of the eyes. 2. Decrease the amount of salt in the diet. 3. Eye medications will need to be administered for life. 4. Decrease fluid intake to control the intraocular pressure.

3. Rationale: The administration of eye drops is a critical component of the treatment plan for the client with glaucoma. The client needs to be instructed that medications will need to be taken for the rest of his or her life. Options 1, 2, and 4 are not accurate instructions.

754. The nurse is caring for a client following craniotomy for removal of an acoustic neuroma. Assessment of which cranial nerve would identify a complication specifically associated with this surgery? 1. Cranial nerve I, olfactory 2. Cranial nerve IV, trochlear 3. Cranial nerve III, oculomotor 4. Cranial nerve VII, facial nerve

4. Rationale: An acoustic neuroma (or vestibular schwannoma) is a unilateral benign tumor that occurs where the vestibulocochlear or acoustic nerve (cranial nerve VIII) enters the internal auditory canal. It is important that an early diagnosis be made because the tumor can compress the trigeminal and facial nerves and arteries within the internal auditory canal. Treatment for acoustic neuroma is surgical removal via a craniotomy. Assessment of the trigeminal and facial nerves is important. Extreme care is taken to preserve remaining hearing and preserve the function of the facial nerve. Acoustic neuromas rarely recur following surgical removal.

763. The nurse is providing instructions to a client who will be self-administering eye drops. To minimize systemic absorption of the eye drops, the nurse should instruct the client to take which action? 1. Eat before instilling the drops. 2. Swallow several times after instilling the drops. 3. Blink vigorously to encourage tearing after instilling the drops. 4. Occlude the nasolacrimal duct with a finger after instilling the drops.

4. Rationale: Applying pressure on the nasolacrimal duct prevents systemic absorption of the medication. Options 1, 2, and 3 will not prevent systemic absorption. Test-Taking Strategy: Focus on the subject, systemic effects. Eating and swallowing are comparable or alike and are not related to the systemic absorption of eye drops. Blinking vigorously to produce tearing may result in the loss of the administered medication.

743. The nurse is performing an admission assessment on a client with a diagnosis of detached retina. Which sign or symptom is associated with this eye disorder? 1. Total loss of vision 2. Pain in the affected eye 3. A yellow discoloration of the sclera 4. A sense of a curtain falling across the field of vision

4. Rationale: A characteristic manifestation of retinal detachment described by the client is the feeling that a shadow or curtain is falling across the field of vision. No pain is associated with detachment of the retina. Options 1 and 3 are not characteristics of this disorder. A retinal detachment is an ophthalmic emergency and even more so if visual acuity is still normal.

746. The nurse is performing an assessment on a client with a suspected diagnosis of cataract. Which clinical manifestation should the nurse expect to note in the early stages of cataract formation? 1. Diplopia 2. Eye pain 3. Floating spots 4. Blurred vision

4. Rationale: A gradual, painless blurring of central vision is the chief clinical manifestation of a cataract. Early symptoms include slightly blurred vision and a decrease in color perception. Options 1, 2, and 3 are not characteristics of a cataract.

765. Which medication, if prescribed for the client with glaucoma, should the nurse question? 1. Betaxolol 2. Pilocarpine 3. Erythromycin 4. Atropine sulfate

4. Rationale: Options 1 and 2 are miotic agents used to treat glaucoma. Option 3 is an antiinfective medication used to treat bacterial conjunctivitis. Atropine sulfate is a mydriatic and cycloplegic (also anticholinergic) medication, and its use is contraindicated in clients with glaucoma. Mydriatic medications dilate the pupil and can cause an increase in intraocular pressure in the eye.

744. The nurse is performing an otoscopic examination on a client with mastoiditis. On examination of the tympanic membrane, which finding should the nurse expect to observe? 1. A pink-colored tympanic membrane 2. A pearly colored tympanic membrane 3. A transparent and clear tympanic membrane 4. A red, dull, thick, and immobile tympanic membrane

4. Rationale: Otoscopic examination in a client with mastoiditis reveals a red, dull, thick, and immobile tympanic membrane, with or without perforation. Postauricular lymph nodes are tender and enlarged. Clients also have a low-grade fever, malaise, anorexia, swelling behind the ear, and pain with minimal movement of the head.
