9.1 Care of the Sensory-Impaired Resident: Vision, Hearing & Speech
Key Takeaways
- Always identify yourself by name before touching a resident with visual impairment, explain what you are about to do, and tell them when you are leaving the room so they are not left speaking to an empty room.
- Never rearrange the furniture or personal belongings of a resident with visual impairment without telling them; a familiar room layout is that resident's mobility system and safety net.
- For a resident with hearing loss, face them at eye level in good light, speak in a lower pitch rather than louder, and rephrase rather than simply repeating the same words at higher volume.
- Expressive aphasia means the resident understands but cannot produce words; receptive aphasia means speech is fluent but comprehension is impaired. Both require yes/no questions, extra time, and never finishing the resident's sentences for them.
- In the sighted-guide technique the resident takes the CNA's arm just above the elbow and walks half a step behind; the CNA never pushes, pulls, or grips the resident's arm.
Care of the Sensory-Impaired Resident: Vision, Hearing & Speech
Care Impaired is one of the twelve published North Dakota knowledge-exam subject areas, worth five questions. The handbook defines it as "questions dealing with residents who are physically or mentally limited from receiving 'standard' care. CNAs must perform more extensively or differently to accommodate these residents." In other words: the care goal does not change, but the method does.
Sensory loss is the most common form of impairment in long-term care, and its consequences are badly underestimated. Untreated vision and hearing loss produce social withdrawal, falls, malnutrition, and behavior that is routinely misread as dementia.
1. Visual Impairment
Common causes in older residents
| Condition | What the resident experiences |
|---|---|
| Cataracts | Clouding of the lens; blurred, hazy vision, faded colors, and severe glare sensitivity, especially at night |
| Glaucoma | Damage to the optic nerve from raised intraocular pressure; peripheral (side) vision is lost first, leaving "tunnel vision" |
| Macular degeneration | Loss of central vision; the resident sees around the edges but a blur or blank sits in the middle of the visual field |
| Diabetic retinopathy | Damaged retinal vessels; patchy, fluctuating vision and floaters |
| Presbyopia | Age-related loss of near focus; nearly universal after about age 45 |
Notice the mirror image: glaucoma takes the edges, macular degeneration takes the center. That contrast is a favorite exam distinction, and it changes practical care — a resident with macular degeneration may walk a hallway confidently but be unable to see the food on the plate.
CNA interventions
+-----------------------------------------------------------------------------+
| CARING FOR A RESIDENT WITH VISION LOSS |
| |
| [ANNOUNCE] ---> Identify yourself BY NAME on entering. Never touch |
| first. Say when you are LEAVING the room. |
| [ORIENT] ---> Describe the room and the location of the call light, |
| water, and personal items - then LEAVE THEM THERE. |
| [NEVER MOVE] ---> Do not rearrange furniture or belongings without |
| telling the resident. The layout IS their map. |
| [LIGHT] ---> Bright, even, glare-free light; nightlights on. |
| [DEVICES] ---> Glasses clean, on the face, and in the labeled case |
| when not worn. Report scratches or a broken frame. |
| [MEALS] ---> Use the CLOCK METHOD to describe the plate. |
| [DIGNITY] ---> Speak to the resident, not to a companion about them. |

The sighted-guide technique
Ambulating a resident with visual impairment is a printed exam favorite because the intuitive move is the wrong one:
- Offer your arm; the resident grasps your arm just above the elbow.
- Walk half a step ahead; the resident follows half a step behind and slightly to the side.
- Announce changes as you reach them: "Two steps down, starting now." "The doorway narrows here — I'll go first."
- To seat the resident, place their hand on the back or arm of the chair and let them lower themselves.
- Never push the resident ahead of you, pull them by the wrist, or grip their arm and steer.
[!NOTE] Guide dogs and white canes. A working guide dog in harness is not a pet. Do not pet, feed, distract, or command it, and speak to the handler, not the dog. Never grab or move a resident's white cane; it is placed within reach exactly like a call light.
2. Hearing Impairment
Age-related hearing loss (presbycusis) is usually gradual, bilateral, and hits high-frequency sounds first — which is why consonants blur into mush while vowels stay audible, and why shouting makes speech less intelligible rather than more.
Behavioral clues a CNA should notice and report
- Turning one ear toward the speaker, or leaning in
- Answering questions that were not asked; inappropriate responses
- Speaking unusually loudly without realizing it
- Television or radio volume set very high
- Withdrawal from group activities and meals; new suspiciousness or irritability
- Complaints of ringing in the ears (tinnitus)
How to communicate
| Do | Don't |
|---|---|
| Get the resident's attention first; make eye contact before speaking | Start talking from the doorway or from behind |
| Stand or sit at eye level, in good light, facing the resident so lips and expression are visible | Cover your mouth, chew gum, or turn away mid-sentence |
| Lower your pitch and speak clearly at a moderate pace | Shout — shouting raises pitch and distorts consonants |
| Rephrase if not understood | Repeat the identical sentence louder |
| Reduce background noise: television off, door closed | Compete with a TV, cart, or hallway conversation |
| Write key words or use a picture/communication board | Give up and speak only to the family member |
| Confirm understanding by asking the resident to repeat the plan back | Assume a nod means comprehension |
Hearing aids
Hearing aids are expensive, small, and lost constantly, and their care is a scored CNA responsibility.
- Turn the aid off before removing it to avoid squealing feedback; turn the volume down before inserting, then adjust up.
- Clean the earmold with a dry cloth or the supplied brush. Never immerse a hearing aid in water or use alcohol.
- Remove hearing aids before showering, bathing, or using a hair dryer.
- Open the battery door when storing overnight to preserve battery life; store in a labeled case, never in a tissue on the overbed table where it will be thrown out.
- Report whistling (feedback), no sound, or a distorted signal — often earwax on the mold, a dead battery, or an aid set to the wrong program.
[!TIP] Whistling has a simple first check. Persistent feedback usually means the earmold is not seated properly in the ear canal or is coated with cerumen. Reseat it and inspect the mold before assuming the device is broken.
3. Speech Impairment and Aphasia
Aphasia is a language disorder, most often after a stroke affecting the left hemisphere. It is not a loss of intelligence, and treating the resident as if it were is a dignity violation as well as a clinical error.
| Type | What is impaired | What the CNA sees |
|---|---|---|
| Expressive (Broca's) aphasia | Producing language | The resident understands you but cannot find or form words; speech is halting and effortful; they are visibly frustrated by their own speech |
| Receptive (Wernicke's) aphasia | Understanding language | Speech is fluent and well-paced but the content is jumbled or nonsensical; the resident does not follow directions and may not realize the problem |
| Global aphasia | Both | Severe impairment of expression and comprehension |
| Dysarthria | Muscle control for speech | Language is intact; speech is slurred, slow, or weak because the muscles are weak — common after stroke and in Parkinson's disease |
Communication strategies
- Give time. Sit down. Silence is not failure; it is processing. A resident with expressive aphasia may need thirty seconds to produce a word.
- Do not finish sentences or supply the word unless the resident asks you to. Finishing sentences is the fastest way to make a resident stop trying.
- Ask yes/no questions — "Are you in pain?" rather than "How are you feeling today?"
- One idea at a time, in short simple sentences. Do not string three instructions together.
- Use gestures, pointing, pictures, communication boards, and writing, and accept whatever channel works.
- Reduce distractions — turn off the television before starting a conversation.
- Watch for and report signs of frustration, tearfulness, or withdrawal, and never speak about the resident in the third person while standing beside them.
[!IMPORTANT] Never assume a resident who cannot speak cannot hear or understand. This applies to aphasia, laryngectomy, tracheostomy, ventilator dependence, and end-stage dementia alike. Hearing is often the last sense to fade. Continue to explain every procedure, address the resident by name, and never discuss their condition over their body as though they were furniture.
4. Putting It Together on the Exam
Care Impaired questions almost always test the same underlying principle: the impairment changes the method, never the standard of care, and never the resident's right to participate. When two answer options both look safe, the correct one is nearly always the one that preserves the resident's remaining independence and choice — describing the plate rather than feeding, guiding rather than pushing, rephrasing rather than giving up.
A CNA enters the room of a resident with advanced macular degeneration to assist with morning care. What is the correct first action?
A resident with presbycusis repeatedly answers questions incorrectly. Which approach is most likely to improve communication?
A resident recovering from a left-hemisphere stroke clearly understands instructions and follows them accurately, but struggles visibly to produce words and becomes frustrated mid-sentence. Which impairment is this, and what should the CNA do?
Which action reflects correct sighted-guide technique when ambulating a resident with visual impairment down a hallway?
