Observation and Charting Vocabulary Practice

  1. The nurse wrote “BP” on the chart as an abbreviation for blood pressure, which is a shortened version of the complete medical term.

Module 15: 5 CNA Dialogues for English Learners

Module 15: Observation and Charting Vocabulary

Dialogue 1: Shift Report and Care Planning

Setting: Two CNAs discussing a resident during shift change

Maria (Day Shift CNA): Good evening, Sarah. Let me give you the report on Mrs. Johnson in room 205.

Sarah (Night Shift CNA): Sure, I’m ready to take notes on her care plan.

Maria: Her ADL status has changed since yesterday. She needed more assistance with bathing and dressing today.

Sarah: Should I document that as an objective observation or subjective?

Maria: Objective – you can see that she couldn’t button her shirt independently. Also, her ROM exercises went well this morning. No complaints of pain.

Sarah: Got it. Any incidents to report?

Maria: No incident reports needed today. Her assessment shows she’s stable. Check the Kardex for her medication times.

Sarah: Perfect. I’ll continue monitoring and make observations throughout my shift.


Dialogue 2: Documentation Training

Setting: Experienced CNA training a new employee

Supervisor: Welcome to your first day, Tom. Let me explain our documentation system.

Tom (New CNA): Thank you. I’m excited to learn about the charting process.

Supervisor: First, understand that we use many abbreviations to save time. For example, “ADL” means Activities of Daily Living.

Tom: I see. What’s the difference between objective and subjective observations?

Supervisor: Objective observations are facts you can see or measure, like “blood pressure 120/80.” Subjective observations are what the resident tells you, like “I feel dizzy.”

Tom: That makes sense. What about those longer forms I heard about?

Supervisor: You mean the MDS – Minimum Data Set. It’s a comprehensive assessment we complete regularly. The RAI (Resident Assessment Instrument) includes the MDS and helps us create RAPs – Resident Assessment Protocols.

Tom: When do we complete these assessments?

Supervisor: The ARD – Assessment Reference Day – determines our timeline. Each resident has scheduled assessment dates.


Dialogue 3: Medical Terminology Lesson

Setting: ESL classroom focusing on healthcare vocabulary

Teacher: Today we’ll break down medical terms using root words, prefixes, and suffixes.

Student 1: Can you give us an example?

Teacher: Sure! Take the word “assessment.” The root word is “assess,” meaning to evaluate. What about abbreviations?

Student 2: We use ROM for Range of Motion, right?

Teacher: Exactly! In healthcare, abbreviations save time. ADL stands for Activities of Daily Living – basic self-care tasks.

Student 1: What’s the difference between assessment and observation?

Teacher: Good question! Observation is watching and noting what you see. Assessment is evaluating that information to understand the patient’s condition.

Student 2: Are patient, resident, and client the same?

Teacher: Yes, they’re synonymous terms for the person receiving care. In long-term care, we typically say “resident.”


Dialogue 4: Incident Reporting

Setting: CNA speaking with charge nurse about an incident

CNA: I need to complete an incident report for Mr. Davis.

Charge Nurse: What happened? Give me your objective observations first.

CNA: At 2:30 PM, I found Mr. Davis on the floor beside his bed. He was alert and responsive.

Charge Nurse: Any subjective information from the resident?

CNA: He said he felt dizzy when he stood up and lost his balance. He denied pain.

Charge Nurse: Good observation skills. Did you check his vital signs?

CNA: Yes, blood pressure was low at 90/60. I documented everything in the Kardex and notified you immediately.

Charge Nurse: Perfect. This information will be important for his care plan revision and next assessment. The PHI (Paraprofessional Healthcare Institute) guidelines emphasize thorough incident documentation.

CNA: Should I monitor his ADL abilities more closely now?

Charge Nurse: Absolutely. Include ROM checks and mobility assessment in your observations.


Dialogue 5: Care Plan Meeting

Setting: Healthcare team discussing resident care

RN: Let’s review Mrs. Thompson’s updated care plan based on her recent MDS completion.

CNA: I’ve been doing daily observations. Her ADL independence has improved significantly.

Physical Therapist: Her ROM exercises are showing results. She can dress herself now with minimal assistance.

RN: Excellent objective data. Any subjective complaints from the resident?

CNA: She mentioned feeling more confident during transfers. That’s important for her assessment.

Social Worker: The RAP recommendations suggest continued independence training.

RN: Good. Tom, update the Kardex with these changes. Use proper abbreviations and medical terminology.

CNA: I’ll include both objective measurements and subjective feedback in my charting.

RN: Remember, accurate documentation protects both the resident and our facility. If anything unusual happens, complete an incident report immediately.

Physical Therapist: The ARD for her next full assessment is coming up next month.

RN: Perfect. Continue monitoring and make detailed observations. This resident’s progress shows the importance of our comprehensive RAI system.


Key Learning Points:

  • Objective vs. Subjective observations
  • Proper use of medical abbreviations
  • Understanding assessment tools (MDS, RAI, RAP)
  • Documentation in Kardex and care plans
  • Incident report procedures
  • Medical terminology structure (root words, prefixes, suffixes)
  • Synonymous terms: patient/resident/client
