What it means
The person has trouble expressing what they think or understanding what is said to them in words. It can stem from damage to the language areas of the brain, trouble articulating, a device that prevents speech, or not sharing a language with the care team.
Explanation written by our team. The official definition is in the NANDA-I 2024-2026 book.
When to use it
Clinical situations where it commonly shows up. The diagnosis is confirmed by your assessment, not by the medical diagnosis.
- Stroke with expressive, receptive or mixed aphasia.
- Dysarthria from stroke, multiple sclerosis, Parkinson's disease or amyotrophic lateral sclerosis.
- Intubated patients or patients with a tracheostomy and no speaking valve.
- The period after a seizure with temporary language disturbance.
- Patients who do not speak English, or who speak another language, with no interpreter available.
- Surgery or injury to the mouth, tongue, jaw or larynx.
What to assess
- Type of impairment: can't find words (expressive), can't follow commands (receptive), or understands and knows what to say but articulates poorly (dysarthria).
- Comprehension using simple one- and two-step commands: “close your eyes,” “touch your nose with your right hand.”
- Expression: naming common objects (pen, watch), repeating a short phrase, answering yes/no reliably.
- Reading and writing, and whether they can point to pictures or letters.
- Hearing, vision, use of glasses or a hearing aid, and dentures.
- Level of consciousness (Glasgow) and orientation, so aphasia is not mistaken for confusion.
- Primary language, education and how the patient communicated before admission (ask the family).
- Frustration, crying or withdrawal when they can't make themselves understood.
Defining characteristics
Assessment findings that support the diagnosis. They go in the "as evidenced by" part of the statement.
- Can't find words or substitutes one word for another (“give me the… the drinking thing”).
- Speaks in one- or two-word phrases or produces no speech.
- Does not follow simple verbal commands despite being awake.
- Speaks fluently but with meaningless words and seems unaware of it.
- Slow, slurred or hard-to-understand speech.
- Inconsistently answers yes when meaning no, or vice versa.
- Uses gestures, points or draws to ask for what they need.
- Cannot speak because of an endotracheal tube or tracheostomy tube.
- Shows anger, cries or stops trying to communicate.
- Does not share a language with the staff caring for them.
Related factors
The causes nursing can act on. They go in the "related to" part of the statement.
- No alternative communication system (communication board, whiteboard, picture cards).
- No interpreter or family member available to translate.
- Noisy, rushed environment or many people talking at once.
- Hearing aid, glasses or dentures not in place.
- Staff who speak fast, use long sentences or ask open-ended questions.
- Fatigue or uncontrolled pain that reduces the ability to concentrate.
- Family who doesn't know how to communicate with the patient.
At-risk populations
- Older adults after a stroke.
- ICU patients on mechanical ventilation.
- Patients with a new tracheostomy.
- Hospitalized patients who speak a different language from the staff.
- People with preexisting hearing loss.
Associated conditions
- Ischemic or hemorrhagic stroke of the dominant hemisphere.
- Traumatic brain injury and brain tumors.
- Neuromuscular and degenerative diseases (Parkinson's, ALS, multiple sclerosis).
- Endotracheal intubation and tracheostomy.
- Head and neck surgery.
- Postictal state after a seizure.
How to write it (PES)
Impaired verbal communication related to lack of an alternative communication system and a noisy, distracting environment as evidenced by inability to name 4 of 5 common objects, one- to two-word phrases, use of gestures to ask for water, and crying when not understood.
Impaired verbal communication (00051).
What nursing can address: the lack of an alternative method, environmental barriers, no interpreter. The stroke or the intubation is documented as an associated condition.
What you observed: how many objects they name, how long their phrases are, whether they follow commands, which gestures they use. Avoid writing only “does not speak.”

Goals / expected outcomes
Written in measurable terms: what, how much and by when.
- The patient answers yes/no reliably (by voice, gesture or card) on 9 of 10 questions within 48 hours.
- Uses a communication board or cards to request at least three basic needs (water, pain, bathroom) within 72 hours.
- Follows one-step commands on 4 of 5 attempts by the end of the first week.
- The family demonstrates at least three strategies for communicating with the patient before discharge.
- The patient has no episodes of crying or agitation from not being understood during the shift.
Nursing interventions and rationales
| Intervention | Rationale |
|---|---|
| Set up a yes/no code from the first contact (thumbs up, blinking, squeezing a hand) and post it at the bedside. | Gives the patient a reliable way to answer and makes sure the whole team uses the same code. |
| Face the patient and speak slowly, in short sentences with one idea at a time; wait for the answer without rushing. | Lowers the language-processing load and keeps the patient from giving up. |
| Ask closed questions and back them up with gestures or real objects. | A yes/no question or a choice between two objects is easier to answer than an open question. |
| Provide a communication board with pictures, letters and basic needs, or a whiteboard if the patient can write. | When spoken words fail, another channel lets the patient call for help, report pain and take part in their care. |
| Make sure glasses, hearing aid and dentures are in place. | A correctable sensory barrier makes any language disorder worse. |
| Reduce noise: turn off the TV, have one person speak at a time, close the curtain. | Aphasia worsens with distractions; a quiet setting improves comprehension. |
| Request a professional interpreter when the patient doesn't share the language, especially for consent and teaching. | Prevents misunderstandings about important clinical information; family members may leave out or change details. |
| Coordinate a speech-language pathology evaluation and reinforce the prescribed exercises every shift. | Early, repeated rehabilitation supports language recovery. |
| Teach the family not to finish the patient's sentences, not to shout, and to acknowledge their effort. | Preserves the patient's dignity and gives real chances to practice. |

Case study: Aphasia after an ischemic stroke
Patient. A 68-year-old right-handed man with hypertension is admitted to the medical floor on day 2 after an ischemic stroke in the left middle cerebral artery territory, with right-sided hemiparesis.
Assessment
- GCS 14 (E4, V4, M6); awake and attentive.
- Follows one-step commands on 4 of 5 attempts; fails two-step commands.
- Names 1 of 5 common objects; speaks in one- or two-word phrases.
- Reliably answers yes/no by nodding on 7 of 10 questions.
- Points to the cup to ask for water and bangs the side rail when not understood.
- Wears glasses but hasn't had them on since admission.
- His daughter says he used to read the newspaper every day.
Nursing diagnosis
Impaired verbal communication related to lack of an alternative communication system and environmental barriers as evidenced by naming 1 of 5 objects, one- to two-word phrases, use of gestures to ask for water, and anger when not understood, in a patient with ischemic stroke (associated condition).
Goal
The patient will use a picture board to request at least three basic needs within 72 hours.
Interventions
- Put on his glasses and provide a board with pictures for water, pain, bathroom, cold and family.
- Agree on yes = thumbs up and post it at the bedside.
- Face him when speaking, with short sentences and closed questions.
- Turn off the TV during visits and assessments.
- Request a speech-language pathology consult.
- Teach his daughter to wait for his answers without finishing them for him.
Evaluation
At 72 hours he asks for water, reports pain and requests the bedpan by pointing to the board, and answers yes/no with his thumb on 10 of 10 questions. He still cannot name objects. The diagnosis remains active with this week's goal: following two-step commands.
How it differs from similar diagnoses
- Risk for impaired verbal communication (00434): There is no language impairment yet, but there are factors that make it likely (for example, a planned intubation).
- Acute confusion (00128): If the patient doesn't understand or answers incoherently because attention and consciousness fluctuate, the problem is acute confusion, not language.
- Impaired social interaction (00052): Focuses on the quality of relationships with other people, not on the ability to produce or understand words.
- Readiness for enhanced verbal communication (00368): A health promotion diagnosis: the person communicates and wants to improve how they do it.
Common mistakes
- Writing “related to stroke” as the only factor: the stroke is the associated condition; name what nursing can change.
- Confusing aphasia with confusion or cognitive impairment and treating the patient as if they understand nothing.
- Speaking louder to a patient with aphasia who hears normally.
- Leaving out how the patient responds (gestures, board) in the shift documentation.
- Using a minor family member as an interpreter for clinical information.

Frequently asked questions
What is the NANDA code for impaired verbal communication?
00051. It belongs to Domain 5 (Perception/cognition), Class 5 (Communication), and is still current in the 2024-2026 edition.
Does an intubated patient have impaired verbal communication?
Yes, if they are awake and cannot speak because of the tube. The factor you act on is the lack of an alternative method; the intubation is the associated condition.
What's the difference between aphasia and dysarthria?
In aphasia, language itself fails: finding or understanding words. In dysarthria, language is intact, but the muscles used to articulate don't work properly.
Can I use this diagnosis for a language barrier?
Yes. A language barrier blocks verbal communication with the care team even if the person has no injury at all.
When do I resolve this diagnosis?
When the person can reliably communicate their needs and understand instructions, either by voice or with a stable alternative method.
