Chapter 10: Visual and Auditory Problems Flashcards
The nurse is reviewing medications that have been prescribed for several clients who have disorders of the eye. Which medication prescription is the most important to discuss with the health care provider?
- Timolol for open-angle glaucoma
- Cromolyn sodium for allergic conjunctivitis
- Atropine for acute angle-closure glaucoma
- Ranibizumab for wet age-related macular degeneration
Ans: 3
Atropine should not be used for acute angle-closure glaucoma. Atropine causes dilation of the pupil, which impedes outflow of aqueous humor and increases intraocular pressure. This action could precipitate or worsen the condition. Focus: Prioritization.
The nurse is working in an ambulatory care clinic. A client calls to report redness of the sclera, itching of the eyes, and increased lacrimation for several hours. What should the nurse direct the caller to do first?
- “Please call your health care provider” (e.g., decline to advise).
- “Apply a cool compress to your eyes.”
- “If you are wearing contact lenses, remove them.”
- “Take an over-the-counter antihistamine.”
Ans: 3
If the client is wearing contact lenses, the lenses may be causing the symptoms, and removing them will prevent further eye irritation or damage. Policies on giving telephone advice vary among institutions, and knowledge of the facility policy is essential. The other options may be appropriate, but additional information is needed before suggesting anything else. Focus: Prioritization.
At a community health clinic, the nurse is teaching a community group about the prevention of accidental eye injuries. What is the most important thing to stress?
- Workplace policies for handling chemicals should be followed.
- Children and parents should be cautious about aggressive play.
- Protective eyewear should be worn during sports or hazardous work.
- Emergency eyewash stations should be established in the workplace.
Ans: 3
Most accidental eye injuries (90%) could be prevented by wearing protective eyewear for sports and hazardous work. Other options should be considered in the overall prevention of injuries. Focus: Prioritization.
A nursing student is assisting an older client who is alert, conversant, and cognitively intact. The client has decreased vision related to macular degeneration. When would the supervising nurse intervene?
- Student puts call bell and personal items within reach and locates each item by guiding the client’s hand.
- Student closes the curtains and turns off all of the lights at the end of the shift to encourage rest and sleep.
- Student talks to the client about family and asks, “So, when was the last time that you saw your uncle?”
- Student assists during mealtime by opening packages and describing location of foods by using clock coordinates.
Ans: 2
For clients who retain some vision, the room should be well-lit; even at night, there should be a night light. Other options are correct actions. Words such as “see, “look,” or “view” are parts of normal speech, and it’s acceptable and natural to use these terms (e.g., “Well, it looks like you had a quiet day today”). Focus: Supervision.
Which clients would be best to assign to the most experienced nurse in an ambulatory care center that specializes in vision problems and eye surgery? Select all that apply.
- Client who requires postoperative instructions after cataract surgery
- Client who needs an eye pad and a metal shield applied
- Client who requests a home health referral for dressing changes and eyedrop instillation
- Client who needs teaching about self-administration of eyedrops
- Client who requires an assessment for recent and sudden loss of sight 6. Client who requires preoperative teaching for laser trabeculoplasty
Ans: 1, 3, 5, 6
Providing postoperative and preoperative instructions, making home health referrals, and assessing for needs related to loss of vision should be done by an experienced nurse who can give specific details and specialized information about follow-up eye care and adjustment to loss. The principles of applying an eye pad and shield and teaching the administration of eyedrops are basic procedures that should be familiar to all nurses. Focus: Assignment.
Place the following steps for eyedrop administration in the correct order.
- Gently press on the lacrimal duct for 1 minute.
- Gently pull tissue underneath eye downward to expose lower conjunctival sac.
- Have the client gently close the eye and move it around.
- Have the client look up and instill the number of prescribed drops.
- Hold the dropper and stabilize hand on the client’s forehead.
- Have the client sit down and tilt his or her head slightly backward.
Ans: 6, 2, 5, 4, 3, 1
Have the client sit with the head tilted back. Pulling down the lower conjunctival sac creates a small pocket for the drops. Stabilizing the hand prevents accidentally poking the client’s eye. Having the client look up prevents the drops from falling on the cornea and stimulating the blink reflex. When the client gently moves the eye, the medication is distributed. Pressing on the lacrimal duct prevents systemic absorption. Focus: Prioritization.
Which tasks are appropriate to assign to an LPN/LVN who is functioning under the supervision of an RN? Select all that apply.
- Administering sulfacetamide sodium 10% to a child with conjunctivitis
- Reviewing hand-washing and hygiene practices with clients who have eye infections
- Showing clients how to gently cleanse eyelid margins to remove crusting
- Assessing nutritional factors for a client with age-related macular degeneration
- Reviewing the health history of a client to identify risk for ocular manifestations
- Performing a routine check of a client’s visual acuity using the Snellen eye chart
Ans: 1, 2, 3, 6
Administering medications, reviewing and demonstrating standard procedures, and performing standardized assessments with predictable outcomes in noncomplex cases are within the scope of the LPN/LVN. Assessing for systemic manifestations and behaviors, risk factors, and nutritional factors is the responsibility of the RN. Focus: Assignment.
The nurse is on a camping trip. A man is chopping wood and gets struck in the eye with a piece of debris. On examination, a wood splinter is protruding from his eyeball. What should the nurse do first?
- Have the man lie in the back seat of the car and drive him to the emergency department.
- Gently remove the piece of wood and place a sterile dressing over the eye.
- Stabilize the area by carefully resting a plastic cup on the orbital rim and taping it in place.
- Flush the eye with copious amounts of clean tepid water; then check visual acuity.
Ans: 3
Penetrating objects should not be removed or disturbed by anyone except an eye specialist because the object may be creating a tamponade effect. Removing or disrupting the object could result in additional damage to the eye. The man needs to have emergency care, and 911 should be called, but if there are no emergency services available, the man should sit in the back seat of the car with a seat belt in place for transport to the nearest facility. After a penetrating eye injury has been assessed and treated by an ophthalmologist, there is a possibility that based on the ophthalmologist’s recommendations, foreign body removal, flushing, and dressing application could be accomplished in the emergency department; however, penetrating objects frequently require surgical removal. Antibiotics and a tetanus immunization are administered before the client is transferred to the operating room. Focus: Prioritization.
The nurse is interviewing an older woman and discovers that she has been taking her glaucoma eyedrops by mouth for the past week. What should the nurse do first?
- Obtain a prescription for tonometry so that her intraocular pressure can be checked.
- Try to determine how frequently and how much she has been ingesting.
- Ask her how she decided to take the drops orally instead of instilling them as eyedrops.
- Call the Poison Control Center and be prepared to describe untoward side effects.
Ans: 2
Try to find out the amount and frequency that she has been taking the drops by mouth. This information will be needed when calling the ophthalmologist or Poison Control. A good follow-up question is to try to find out why she is taking the drops by mouth. She may be very confused, or there may have been an error of omission in client education by all health care team members who were involved in the initial prescription. Focus: Prioritization; Test Taking Tip: Remember that the first step of nursing process is assessment and gathering sufficient data. Always assess first unless taking the time to assess would be life threatening.
The nurse is working in a community health clinic and a client needs instructions for the care of a hordeolum (stye) on the right upper eyelid. What is the first intervention that the client should try?
- Apply warm compresses four times per day.
- Gently perform hygienic eyelid scrubs.
- Obtain a prescription for antibiotic drops.
- Contact the ophthalmologist.
Ans: 1
Warm compresses usually provide relief. If the problem persists, eyelid scrubs and antibiotic drops would be appropriate. The ophthalmologist could be consulted, but other providers such as the family physician or the nurse practitioner could give a prescription for antibiotics. Focus: Prioritization.
Which finding should be immediately reported to the health care provider?
- A change in color vision
- Crusty yellow drainage on the eyelashes
- Increased lacrimation
- A curtainlike shadow across the visual field
Ans: 4
A curtainlike shadow is a symptom of retinal detachment, which is an emergency situation. A change in color vision is a symptom of cataract. Crusty drainage is associated with conjunctivitis. Increased lacrimation is associated with many eye irritants, such as allergies, contact lenses, or foreign bodies. Focus: Prioritization; Test Taking Tip: NCLEX® Examination questions frequently test the ability to identify life-threatening conditions, or in this case, the risk for permanent disability. In preparing to take the NCLEX® Examination, pay attention to signs and symptoms that signal life- threatening conditions and those that could lead to permanent injury.
In the care of a client who has sustained recent blindness, which tasks would be appropriate to delegate to unlicensed assistive personnel (UAP)? Select all that apply.
- Counseling the client to express grief or loss
- Assisting the client with ambulating in the hall
- Orienting the client to the surroundings
- Encouraging independence
- Obtaining supplies for hygienic care
- Storing personal items to reduce clutter
Ans: 2, 5
Assisting the client with ambulating in the hall and obtaining supplies are within the scope of practice of the UAP. Counseling for emotional problems, orienting the client to the room, and encouraging independence require formative evaluation to gauge readiness, and these activities should be the responsibility of the RN. Storing items and rearranging furniture are inappropriate actions because the client needs be able to consistently locate objects in the immediate environment. Focus: Delegation; Test Taking Tip: Remember to differentiate whether the question is about an acute or chronic condition. The nurse could delegate more tasks to the UAP if the client’s condition is chronic. For example, a client who has been blind for a long time is less likely to need the nurse to prompt or assess independence. However, for a client with a severely depressed respiratory rate, the nurse would not delegate performing this vital sign to the UAP.
After cataract surgery, the client experiences all of the symptoms listed below. Which symptom needs to be immediately reported to the health care provider?
- A scratchy sensation in the operative eye
- Loss of depth perception with the patch in place
- Poor vision 6 to 8 hours after patch removal
- Pain not relieved by prescribed medication
Ans: 4
Pain may signal hemorrhage, infection, or increased ocular pressure. A scratchy sensation and loss of depth perception with the patch in place are common. Adequate vision may not return for 24 hours. Focus: Prioritization.
A client reports a sudden excruciating pain in the left eye with the visual change of colored halos around lights and blurred vision. Which interventions should the nurse expect and perform for this emergency condition? Select all that apply.
- Prepare the client for photodynamic therapy.
- Instill a mydriatic agent, such as phenylephrine.
- Instill a miotic agent, such as pilocarpine.
- Administer an oral hyperosmotic agent, such as isosorbide.
- Apply a cool compress to the forehead.
- Provide a darkened, quiet, and private space for the client.
Ans: 3, 4, 5, 6
The client’s symptoms are suggestive of angle-closure glaucoma. Immediate inventions include instillation of miotics, which open the trabecular network and facilitate aqueous outflow, and intravenous or oral administration of hyperosmotic agents to move fluid from the intracellular space to the extracellular space. Applying cool compresses and providing a dark, quiet space are appropriate comfort measures. Photodynamic therapy is a treatment for age-related macular degeneration. Use of mydriatics is contraindicated because dilation of the pupil will further block the outflow. Focus: Prioritization.
The nurse is preparing to administer a beta-adrenergic blocking glaucoma agent. Which statement made by the client warrants additional assessment and notification of the health care provider?
- “My blood pressure runs a little high if I gain too much weight.”
- “Occasionally, I have palpitations, but they pass very quickly.”
- “My joints feel stiff today, but that’s just my arthritis.”
- “My pulse rate is a little low today because I take digoxin.”
Ans: 4
All beta-adrenergic blockers are contraindicated in bradycardia. Alpha-adrenergic agents can cause tachycardia and hypertension. Carbonic anhydrase inhibitors should not be given to clients with rheumatoid arthritis who are taking high dosages of aspirin. Focus: Prioritization; Test Taking Tip: Beta-adrenergic blockers “block” the receptor sites for epinephrine and norepinephrine, which are responsible for the “fight-or-flight” response; therefore, remember these medications will slow the pulse rate.
