A vital-sign range becomes useful when it is attached to an action: verify the measurement, compare with baseline, assess the patient, recognize a pattern, and escalate the change that threatens perfusion or oxygenation. A memorized number without that response is only half of the exam skill.
Common resting-adult study anchors
- Pulse: 60–100 beats/min
- Respirations: 12–20 breaths/min
- Temperature: 36.5–37.5°C (97.7–99.5°F), varying with route and time of day
- Oxygen saturation: 95–100% on room air
Practice each measurement in context: heart rate and pulse, respiratory rate and pattern, and temperature.
Blood pressure categories
- Normal: systolic below 120 and diastolic below 80 mm Hg.
- Elevated: systolic 120–129 and diastolic below 80 mm Hg.
- Stage 1 hypertension: systolic 130–139 or diastolic 80–89 mm Hg.
- Stage 2 hypertension: systolic at least 140 or diastolic at least 90 mm Hg.
When systolic and diastolic values land in different categories, classify the reading by the higher category. One abnormal reading is also a measurement problem until technique, cuff size, position, recent activity, and baseline are considered.

That card is a NurseSavvy range slider: you set the boundaries yourself instead of recognizing them, which is why it is a retrieval and not a reread. The four vital-sign topics are among the 853 topics with a learning flow; a boundary set wrong brings a read card under 50 words and the same slider again in the session, and the five-step response below is the Take Action rung of the same flow.
Use a five-step response to any abnormal value
- Verify: repeat or confirm technique when appropriate.
- Compare: look for change from the patient’s baseline.
- Assess: connect the number with symptoms and the full pattern.
- Prioritize: identify airway, breathing, circulation, or neurologic threat.
- Communicate: report the trend and associated findings clearly.
Pulse, respiration, temperature, and saturation anchors are the standard adult resting ranges printed in nursing fundamentals textbooks and used by the NCLEX; blood-pressure categories are from the 2025 AHA/ACC blood-pressure guideline summary, checked September 9, 2026.
Clinical-context note: Expected values and escalation thresholds differ by age, pregnancy, diagnosis, medication, measurement site, and facility policy; use the ordered parameters and the patient’s condition in real care.
Common questions
What is a normal adult pulse?
A common resting-adult study anchor is 60–100 beats per minute, interpreted with rhythm, quality, symptoms, medications, activity, and baseline.
What is a normal adult respiratory rate?
The MedlinePlus resting-adult reference range is 12–18 breaths per minute. Course references may use a slightly different upper boundary; pattern, depth, effort, oxygenation, symptoms, and baseline matter with the number.
What is considered normal blood pressure?
The 2025 AHA/ACC framework defines normal adult blood pressure as systolic below 120 and diastolic below 80 mm Hg.
What should a nurse do with an abnormal vital sign?
Verify technique when appropriate, compare with baseline, assess associated cues and the overall pattern, identify immediate ABC or neurologic threats, and communicate or intervene according to the patient and policy.
