6.1 Vital Signs

Key Takeaways

  • Vital signs include temperature, pulse, respirations, blood pressure, oxygen saturation when assigned, and pain reporting.
  • Know normal adult ranges, but always follow facility-specific reporting thresholds.
  • Respirations should be counted without causing the resident to consciously alter breathing.
  • Blood pressure measurement requires correct cuff placement and quiet positioning.
  • Abnormal or sudden vital-sign changes must be reported promptly.

Vital Signs Basics

Vital signs are measurements that help the nurse assess resident condition. CNAs collect and report them; they do not diagnose based on them.

Vital SignCommon Adult Reference
Oral temperatureAbout 98.6 F, varies normally
Pulse60-100 beats per minute
Respirations12-20 breaths per minute
Blood pressureOften around 120/80 mmHg, varies by resident
Oxygen saturationFollow facility range and nurse direction

Temperature

Report fever, low temperature, or sudden change according to policy. Also report symptoms that go with temperature change, such as chills, sweating, confusion, or weakness.

Pulse

Measure pulse rhythm and rate. Report very fast, very slow, irregular, weak, or bounding pulse. If the resident has chest pain or shortness of breath, report immediately.

Respirations

Respirations should be counted quietly. If the resident knows you are counting, they may change the pattern.

Report labored breathing, noisy breathing, shallow breathing, bluish color, or inability to speak in full sentences.

Blood Pressure

Place the cuff on the bare upper arm unless policy or equipment indicates otherwise. The arm should be supported and relaxed.

Do not use an arm with an IV, injury, dialysis access, or other restriction. Ask the nurse if unsure.

Exam Tip

Vital signs questions often combine measurement with judgment. The correct CNA action is usually to measure accurately, record correctly, and report abnormal findings.
