Objective. Students will perform a complete set of all five vital signs on a simulated resident in sequence while maintaining infection control and patient dignity, then enter results into a simulated electronic health record with no transcription errors.
This lesson, its worked examples and its practice questions has not yet been verified by a licensed clinician in the field or by a certification or approval body. It is a study draft and may contain errors. Do not use it to make decisions about any patient or medication. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
Measuring vital signs one at a time in isolation is a training step. In real practice, you will perform all five measurements — temperature, pulse, respiration, blood pressure, and oxygen saturation (SpO₂) — as a single, flowing procedure. Combining them saves the resident's time and energy, reduces the number of times you disturb them, and lets you detect patterns across signs that a single measurement would miss. The state CNA competency evaluation expects you to perform this sequence correctly, safely, and efficiently.
Gather all equipment before approaching the resident: thermometer with probe cover, pulse oximeter, blood pressure cuff and stethoscope, watch with a second hand, and your documentation form or EHR login. Confirm the cuff size is appropriate for the resident's arm. Wash your hands or use hand sanitizer outside the room. Knock and wait before entering — this simple act protects dignity and is a critical step on your skills checklist.
Introduce yourself by name and role every time. Explain what you are about to do in plain language: "I'm going to check your temperature, pulse, breathing, blood pressure, and oxygen level. It will take just a few minutes." Obtain verbal agreement before touching the resident. Provide privacy by closing the curtain or door. Apply gloves if contact with mucous membranes or body fluids is anticipated (for example, oral temperature).
The recommended sequence used in most state-approved CNA curricula is:
1. Temperature — insert the probe and leave it in place while you proceed.
2. Respiration — count breaths while the thermometer is still in position and before you announce that you are removing it. Residents unconsciously alter their breathing rate when they know it is being watched. Counting during thermometry keeps the measurement accurate.
3. Pulse — after respiration, move to the radial pulse. You may also obtain pulse and SpO₂ simultaneously if your pulse oximeter displays heart rate.
4. SpO₂ — clip the pulse oximeter to a fingertip and allow it to stabilize (usually 15–30 seconds) while you prepare for blood pressure.
5. Blood pressure — last, because the cuff inflation can briefly cause discomfort and affect the resident's relaxed state.
Write down each result on your pocket notepad immediately — do not rely on memory.
Skipping any of these steps is a critical error on the skills checklist and a patient safety risk.
After all measurements, remove the blood pressure cuff, return the resident to a comfortable position, lower the bed if it was raised, and ensure the call light is within reach. Thank the resident and tell them you will record the results. Remove gloves if still worn, perform hand hygiene, and exit.
Documentation must happen as soon as you leave the room — delays increase transcription errors. In the EHR training module:
Correcting a paper error: Draw a single line through the incorrect value so the original is still readable, write the correct value nearby, and add your initials and the date. Never use correction fluid (white-out). The same principle applies to EHR systems with a correction or amendment function — always follow your facility's policy.
The practice target for the full integrated procedure is completion in under 15 minutes. Speed matters in clinical work, but accuracy and safety come first. If you are cutting steps to meet the time, slow down. On the state competency evaluation, a single critical-step omission — such as failing to perform hand hygiene or failing to introduce yourself — results in failure of that skill, regardless of how well the rest of the procedure is performed.
Use the full-procedure checklist during every practice run. Have your evaluator mark each step in real time. After the run, review any missed steps and repeat the procedure before your next scheduled shift.
Answer each question, then check it. Nothing is recorded; this is your own practice.

Does the school offer financial aid?
No. We don’t offer financial aid because we’re free. No, really: completely free.
Do you offer industry certification?
No. We are not certified yet, so we can’t offer that to students. What we do offer is knowledge and understanding of a trade.
