8.2 Vital Signs: Radial Pulse & Respirations

Vital Signs Inside Basic Nurse Skills

Among the ~10 Basic Nurse Skills knowledge questions, vital signs — especially pulse and respirations — are high-frequency content. Temperature and blood pressure appear in training and workplace practice, but the Wisconsin Headmaster skills pool specifically includes Vital Signs: Radial Pulse + Respirations as a scored task. That means you must perform a textbook radial pulse count, a textbook respiration count, and record both correctly under the evaluator's eyes.

Vital signs give an early picture of how the body is coping. A CNA's role is to:

1. Measure using correct technique
2. Record accurately
3. Compare to normal ranges and the resident's usual baseline
4. Report abnormal or changed findings to the nurse promptly
5. Never invent numbers, guess, or "fix" a reading to look normal

You do not diagnose "tachycardia" as a medical conclusion for the chart in a way that replaces nursing judgment — you report the rate, rhythm observations, and associated symptoms in objective language.

What "Vital Signs" Include (Big Picture)

*Memorize facility norms and individual baselines. An athlete may live at a pulse of 52; for them 52 may be normal, while 52 in a usually-80 resident after a fall is urgent. Always think baseline + symptoms, not only textbook cutoffs.

Radial Pulse: Location and Technique

The radial pulse is felt on the thumb side of the inner wrist, where the radial artery runs near the surface. It is the pulse Wisconsin skills testing expects you to count.

Step-by-Step Radial Pulse (Skills-Ready)

1. Introduce yourself, identify the resident, explain you will check the pulse, provide privacy if needed, and perform hand hygiene.
2. Position the resident comfortably, arm supported, palm up if possible.
3. Place the pads of your index and middle fingers (sometimes three fingers) over the radial artery. Do not use your thumb — your thumb has its own pulse and can confuse the count.
4. Press lightly until you feel a regular beat; too hard can obliterate the pulse.
5. Count beats for one full minute (60 seconds). The Wisconsin skill sheet offers no 30-second shortcut, and it adds a step candidates routinely forget: tell the RN Test Observer when you start counting and tell them when you stop. Some employers allow 30 seconds × 2 for regular pulses in daily practice; that habit costs you scored steps on test day.
6. Note rate, and observe whether the rhythm feels regular or irregular and whether the force feels strong or weak (report quality in words if trained to do so).
7. Record the number immediately; do not rely on memory after other care.
8. Report rates outside parameters, new irregularity, weak thready pulse with symptoms, or resident complaints of chest pain, palpitations, or dizziness.

Pulse Vocabulary for Reporting

If you cannot find a radial pulse, do not invent one. Reposition fingers, try the other wrist if appropriate, and get the nurse if the pulse is absent or the resident looks unstable. Carotid checks for routine vital signs are not a casual CNA improvisation during skills — stick to the assigned radial method unless emergency protocols apply.

Respirations: Count Without Changing the Pattern

A respiration is one full cycle of inspiration and expiration (chest rise and fall = one breath). Normal adult resting rate is about 12–20 breaths per minute. Factors that change rate include pain, fever, anxiety, activity, lung disease, opioids, and knowing someone is watching you breathe.

Two Audiences: Say Nothing to the Resident, Say It Clearly to the Observer

When people know their breathing is being counted, they often speed up, slow down, or breathe deeper. That ruins accuracy, so the resident is kept unaware. The RN Test Observer is not. Wisconsin scores an explicit announcement on this task: you tell the observer when the respiration count starts and when it stops, exactly as you did for the pulse. Candidates who have absorbed the generic "count breaths discreetly" rule from other states often stay silent through both counts and lose the step.

Standard technique for the Wisconsin task:

1. After finishing the pulse count, keep your fingers on the wrist as if you are still counting the pulse.
2. Watch the chest or abdomen rise and fall (or feel subtle movement if covers make visual hard — still without announcing).
3. Count respirations for one full minute (60 seconds) — again the full minute, and again announce the start and stop of the count to the RN Test Observer while saying nothing about it to the resident.
4. Note rate and whether breathing looks easy, labored, shallow, deep, noisy, or irregular.
5. Record and report abnormalities: very fast or slow rates, difficulty breathing, blue lips, use of neck/shoulder muscles, wheezing, gasping, or new confusion with breathing change.

Respiration Observation Clues

Recording Accuracy: Skills and Knowledge Both Care

On the Wisconsin radial pulse and respirations skill, recording is not optional fluff. The RN Test Observer counts alongside you and compares your written values to their own, using published tolerances:

The respiration window is the tight one: two breaths is a very small margin over a 60-second count, so a distracted count or a rounded guess fails the step outright. You also write both values on a previously signed recording form — practice precise counting rather than planning to use the margin.

Recording habits that prevent errors:

• Write pulse and respirations in the correct blanks; do not swap them.
• Use whole numbers as trained; include units or form fields as required (e.g., "pulse 78," "resp 16").
• Record promptly before leaving the bedside area if the form allows.
• If interrupted mid-count, restart the count — do not patch partial counts from memory.
• Never copy a previous shift's vitals or estimate "about 80."

Sample Documentation Mindset (Facility Forms Vary)

Objective charting example: "Radial pulse 88, regular. Respirations 18, unlabored. Resident denies chest pain." If the pulse is irregular: "Radial pulse 96, irregular. Nurse notified." Stick to what you measured and observed.

When to Report Immediately vs Routinely

Get the nurse now (or activate emergency response per facility) when vitals come with distress:

• Chest pain, pressure, or radiation to arm/jaw with any pulse change
• Sudden dyspnea, inability to speak full sentences, blue color
• Pulse very fast or very slow with dizziness, fainting, or new weakness
• Respirations very slow after pain medication, or absent/near-absent effort
• New irregular pulse with fainting or severe fatigue

Report promptly (same shift / as soon as practical) for values outside ordered parameters even if the resident "looks fine," for new irregularity without acute distress, and for trends (pulse climbing over several checks, respirations rising with fever).

Remember: the nurse integrates vitals with the full clinical picture. Your job is accurate data + timely communication.

Factors That Affect Pulse and Respirations (Exam Favorites)

If you take vitals right after a transfer or heated argument, note the context when reporting: "Pulse 104 after ambulating to bathroom; resting pulse earlier was 78."

Wisconsin Skills Task: Pulse + Respirations Workflow

Treat the skill as one continuous performance:

1. Opening: knock, introduce, identify, explain, hand hygiene, gather watch with second hand (or facility timer), provide privacy as needed.
2. Position arm; locate radial pulse; count per skill sheet duration.
3. Without announcing, count respirations while appearing to continue pulse assessment.
4. Recognize resident comfort; call light in reach; bed safety as required.
5. Record both values on the recording form with required identifiers.
6. Closing hand hygiene and reporting if values are abnormal (in a real facility — on skills, follow whether the evaluator wants verbal report).

Practice with a partner until you can count accurately while making natural conversation after the count, not during it. Nervous candidates often count too fast, lose the artery mid-count, or stare obviously at the chest and trigger fake breathing.

Connecting Vitals to the Rest of Basic Nurse Skills

Pulse and respirations are not isolated trivia. After a difficult transfer, recheck how the resident looks and breathes. After pain medication (administered by the nurse), your observation of sedation and slow breathing protects the resident. When intake is poor and the resident is weak, a rising pulse may support your report of decline. Basic Nurse Skills is the domain where measurement meets mobility and observation — Section 8.4 builds the observation side further.

On test day, if a knowledge stem gives a pulse of 48 in a resting adult who is dizzy, choose report to the nurse immediately, not "recheck next week" or "give orange juice on your own as treatment." Numbers without action are incomplete nursing-assistant practice.
