Communication and Documentation for CNAs: NNAAP Written Exam Guide

This is the final lesson in the free CNA course, Module 6, Lesson 2. Like the previous lesson on resident rights, this topic is tested on the written portion of the NNAAP certification exam, not on the clinical skills test. There is no hands-on evaluation for communication or documentation. You will see multiple-choice questions on the written exam about how to report observations to the nurse, how to correct a documentation error, and how to communicate effectively with residents who have barriers to communication. Getting this material down is your last step before you are ready to take the practice test and then the real thing.

Communication is the foundation of everything a CNA does. Every time you speak with a resident, you are communicating. Every time you write in a chart, you are communicating with the rest of the care team. Every time you report an observation to the nurse, you are part of the chain that keeps residents safe. CNAs spend more time with residents than any other member of the care team, which means you are often the first person to notice a change in a resident's condition. Whether that observation reaches the nurse accurately and promptly depends entirely on your communication skills.

Types of Communication

Communication happens in three ways, and all three matter in a care setting:

Verbal communication is communication through spoken words. This includes everything you say directly to a resident, to a family member, to a nurse, or to a coworker.
Nonverbal communication is communication through body language, facial expressions, posture, eye contact, and touch, everything you convey without using words. Research consistently shows that nonverbal communication carries more emotional weight than what is said. A CNA who speaks kindly but looks rushed, avoids eye contact, and never makes physical contact communicates differently than one whose body language matches their words.
Written communication is documentation: the entries you make in the resident's chart, the intake and output records, the activity logs, and the shift handover notes. Written communication becomes a permanent legal record.

Communicating with Residents

Effective communication with residents is a clinical skill. These are the principles the NNAAP exam tests and that matter in daily practice:

Introduce yourself before speaking. Always say your name and role when you enter a room or begin interacting with a resident, even if you have cared for them before. Residents with cognitive impairment may not recognize you from one visit to the next. Starting with an introduction orients the resident to the interaction.
Use the resident's preferred name. Ask how the resident would like to be addressed. Do not assume a resident named "Margaret" wants to be called "Maggie," or that any resident wants to be called by their first name. Using the name the resident chooses is both a practical communication step and a right.
Face the resident when speaking. Make eye contact at the resident's level. Sit or crouch down rather than speaking from above if the resident is in a chair or bed. Speaking from directly in front of the resident, at the same eye level, makes conversation easier for residents with hearing or vision problems, and signals respect.
Use simple, clear language. Avoid medical jargon when talking to residents. Instead of "I am going to take your BP," say "I am going to check your blood pressure." Plain language prevents confusion and shows that you respect the resident's ability to understand their own care.
Speak clearly at a normal pace. Do not raise your voice unless the resident is hard of hearing and you know that speaking louder helps. Shouting at a resident who does not have a hearing problem is condescending. For residents with hearing loss, speaking louder may help, but so may facing them directly, speaking more slowly, or writing things down.
Allow time for the resident to respond. Some residents: particularly those with dementia, those who are drowsy from medication, or those who have had a stroke, need more time to process what you said and form a response. Wait patiently without filling the silence.

Nonverbal Communication in Care

Your body communicates to residents even when you are not speaking. Common ways nonverbal communication affects the care relationship:

Touch is one of the most powerful ways to communicate care and safety. A hand on the shoulder, holding a resident's hand during a difficult moment, or a gentle touch on the arm when explaining a procedure all signal connection and warmth. Touch must always be appropriate, consensual, and culturally sensitive.
Facial expression reveals what you actually feel. A CNA who looks annoyed, rushed, or disgusted during personal care communicates those feelings to the resident regardless of what is said. Maintaining a calm, attentive expression throughout care, including during difficult tasks, is a professional skill that takes practice.
Posture and body language also communicate. Leaning in toward the resident during conversation signals engagement. Standing with arms crossed, looking at the door, or checking the clock signals that you are in a hurry to leave. Residents notice.

Therapeutic Communication Techniques

Therapeutic communication means using specific techniques to help residents express themselves and feel heard. These are tested on the NNAAP written exam:

Active listening: Giving the resident your full attention, maintaining eye contact, and not interrupting. Active listening is different from waiting for the resident to stop talking so you can respond.
Open-ended questions: Questions that cannot be answered with a simple yes or no. "How are you feeling today?" gets more information than "Are you feeling okay?" Open-ended questions invite the resident to share more and give you better clinical information.
Reflecting and restating: Repeating back what the resident said in slightly different words to confirm you understood. If a resident says "I feel like nobody listens to me," you might respond "It sounds like you have been feeling unheard." This shows you are paying attention and gives the resident a chance to confirm or correct your understanding.
Silence: Sometimes the most therapeutic thing you can do is simply be present without filling the quiet with words. Silence gives the resident space to think, feel, and speak when they are ready.

Barriers to Communication

Many residents in long-term care face one or more barriers that make communication more difficult. Recognizing these barriers is the first step to working around them:

Language differences: Residents whose primary language is not English may struggle to understand or respond in English. Use an interpreter whenever possible. Do not ask family members to interpret medical information, use a professional interpreter service or a trained staff member. Picture boards and translation apps can help with basic communication when a formal interpreter is not available.
Hearing impairment: Check that hearing aids are in place and turned on before attempting to communicate. Face the resident directly so they can see your lips. Speak more slowly and clearly. Reduce background noise. Offer written communication as an alternative.
Vision impairment: Announce yourself by name when entering the room. Describe what you are doing before you touch the resident. Offer large-print materials or read written information aloud.
Cognitive impairment (dementia): Use short, simple sentences with one request at a time. Speak slowly and calmly. Allow plenty of time for the resident to respond. Use nonverbal cues, gestures, pointing, demonstrating, alongside words. Repeat information consistently rather than expecting the resident to remember from one interaction to the next. Do not argue with a resident who has dementia about what is real, redirect instead.
Pain or discomfort: A resident who is in significant pain cannot focus on communication. Address pain first when possible, or factor it into your communication approach.
Medications: Some medications cause drowsiness, confusion, or slowed responses. A resident who is unusually difficult to rouse or who seems more confused than usual after a medication change should be reported to the nurse.

Reporting to the Nurse: Observe and Report

CNAs observe. Nurses assess. Physicians diagnose and treat. These are distinct roles, and the written exam tests whether you understand the difference.

Your job as a CNA is to report what you directly observe, hear, measure, or smell, not to interpret what those observations mean or to decide whether they are significant. When you report an observation to the nurse, use objective, factual language. Objective means based on measurable facts, not opinions or interpretations. Subjective means based on feelings or interpretations. Document and report objective information only.

Examples of objective versus subjective reporting:

Objective: "Mrs. Jones told me she has a headache and rated her pain at 6 out of 10. Her face is flushed. Her blood pressure was 148/92."
Subjective (incorrect for reporting): "Mrs. Jones seems to have high blood pressure."
Objective: "Mr. Rivera refused his lunch tray and said he feels nauseated. He has not eaten since yesterday evening. He vomited approximately 100 mL of clear fluid at 10:15 this morning."
Subjective (incorrect for reporting): "Mr. Rivera looks sick and probably has a stomach bug."

Report changes from the resident's baseline, what is normal for that resident. A blood pressure of 130/85 might be entirely normal for one resident and a significant change for another. Knowing each resident's normal helps you recognize when something is different.

Report to the nurse promptly when you notice: a significant change in a resident's condition, any complaint of pain, chest tightness, or difficulty breathing, a fall or near-fall, any sign of injury, skin changes, a change in mental status or level of responsiveness, or any situation that does not feel right. When in doubt, report. It is never wrong to bring something to the nurse's attention.

SBAR: Structured Communication

Some facilities use a structured communication format called SBAR when CNAs report to nurses. SBAR stands for:

Situation: What is happening right now? ("Mrs. Jones is complaining of chest pain.")
Background: Relevant background information. ("She has a history of heart disease. Her last vital signs were taken at 8am, and her BP was 126/80.")
Assessment: What you think is going on: your observation, not a diagnosis. ("She looks pale and says the pain started about 20 minutes ago.")
Recommendation: What you are asking for or what action you think should happen. ("I think you should come assess her.")

Not all facilities use SBAR for CNA-to-nurse communication, but knowing the framework helps you organize your thoughts before making a report so you do not leave out important information.

Documentation Rules

Documentation in a resident's medical record is a legal document. What you write becomes part of the permanent record that may be reviewed by nurses, physicians, administrators, auditors, and in some cases courts. These rules are absolute:

Document after care is provided, never before. Writing that you gave care before you have given it is falsification of a medical record, a serious offense that can result in loss of certification.
Use objective, factual language. Write what you observed, measured, heard, or smelled. Do not write opinions, judgments, or interpretations.
Use the 24-hour clock (military time). The 24-hour clock eliminates ambiguity between morning and afternoon. Midnight is 00:00. Noon is 12:00. 1pm is 13:00. 2pm is 14:00. Continue adding 12 to any pm time to convert. 9pm is 21:00. This matters because a documentation entry that reads "4:00" could mean 4am or 4pm. In a medical record, that ambiguity can have serious consequences.
Use only approved abbreviations. Each facility maintains a list of approved abbreviations. Using non-approved abbreviations can create confusion. When in doubt, write it out in full.
Correct errors properly. If you make a mistake in a handwritten entry, draw a single line through the error so the original text is still readable, write the word "error" next to it, and initial it. Never use correction fluid (whiteout), never erase, and never write over the mistake so it cannot be read. Obliterating a documentation error looks like an attempt to hide something.
Date, time, and sign every entry. Every entry must include the date, the time in 24-hour format, and your full name and title or title abbreviation (CNA). An unsigned entry has no accountability.
Write legibly. If your handwriting cannot be read, the documentation is effectively useless. Take the time to write clearly.
Never document for someone else. You may only document care that you personally provided. If a coworker asks you to document something on their behalf, decline. They must document their own care.

Change-of-Shift Report

At the end of every shift, care information is passed from the outgoing staff to the incoming staff. This is called the change-of-shift report, end-of-shift report, or handover. CNAs typically participate in this process for the residents they cared for during their shift.

An effective change-of-shift report includes: the resident's current condition and any changes since the previous report, any complaints or concerns the resident expressed, intake and output totals, significant observations (skin changes, mood changes, unusual behavior), care that was completed and care that remains outstanding, and anything the incoming shift needs to watch for or follow up on.

Consistent, accurate handover communication is one of the most important safety tools in any healthcare setting. Most medical errors and adverse events that happen in the first hour of a shift can be traced back to something that was missed or miscommunicated during handover.

Confidentiality in Communication

Everything discussed about HIPAA in the resident rights lesson applies here as well. As a quick reminder: resident health information may only be discussed with people who are directly involved in that resident's care. This means:

Clinical conversations belong in clinical spaces, not hallways or break rooms.
Do not discuss residents with family members who have not been granted access to that resident's information.
Do not share anything about a resident on social media, not names, not room numbers, not diagnoses, not stories, even if you think the resident is not identifiable.
