Purpose
- The pulse is the beat of the heart felt at an artery as a wave of blood passes through the artery. A pulse is felt every time the heart beats.
- The temporal, carotid, brachial, radial, femoral, popliteal, posterior tibial, and dorsalis pedis (pedal) pulses are felt on each side of the body. The radial pulse is used most often. It is easy to reach and find. The person is not exposed.
- The pulse rate is the number of heartbeats or pulses felt or heard in 1 minute.
- The pulse rate is affected by many factors, including activity, drugs, and pain.
- The adult pulse rate is between 60 and 100 beats per minute. A rate of less than 60 or more than 100 is abnormal. Report abnormal pulses at once.
- The pulse rhythm should be regular. That is, pulses are felt in a pattern. The same interval occurs between beats. An irregular pulse occurs when the beats are not evenly spaced or beats are skipped.
- Force relates to pulse strength. A forceful pulse is easy to feel. It is described as strong, full, or bounding. Hard-to-feel pulses are termed weak, thready, or feeble.
- You will take radial and apical pulses. You must count, report, and record accurately.
- The radial pulse is used for routine vital signs. Place the first two or three fingertips against the radial artery. The radial artery is on the thumb side of the wrist. Count the pulse for 30 seconds. Then multiply the number by 2. This gives the number of beats per minute. If the pulse is irregular, count it for 1 minute. In some agencies, all radial pulses are taken for 1 minute. Follow agency policy.
Equipment
Roll cursor over items to see labels. For the purposes of clearly depicting the equipment, a barrier is not shown in this photo. When providing care, a barrier should always be placed on the surface before placing the equipment.
Watch with a second hand
Delegation
- Follow delegation guidelines. Before taking a radial pulse, obtain this information from the nurse and care plan:
- What pulse to take for each person—radial or apical
- When to take the pulse
- What other vital signs to measure
- How long to count the pulse—30 seconds or 1 minute
- If the nurse has concerns about certain patients or residents
- What observations to report and record
- When to report the pulse rate
- What patient or resident concerns to report at once
Preparation
- Observe quality-of-life measures.
- Review the information under Delegation and Safety and Comfort.
- Practice hand hygiene.
- Identify the person. Check the ID bracelet against the assignment sheet. Also call the person by name.
- Provide for privacy.
Safety
- Use your first two or three fingertips to take a pulse. Do not use your thumb. The thumb has a pulse. You could mistake the pulse in your thumb for the person’s pulse. Reporting and recording the wrong pulse can harm the person.
Comfort
- Support the exposed wrist in a non-compromised position for comfort.

- Provide for comfort.
- Place the call light within reach.
- Unscreen the person.
- Complete a safety check of the room.
- Practice hand hygiene.
Reporting/Recording
- Report and record your observations, including:
- The pulse site
- The pulse rate—report at once a pulse rate less than 60 (bradycardia) or more than 100 (tachycardia) beats per minute
- If the pulse is regular or irregular
- Pulse force—strong, full, bounding, weak, thready, or feeble
Review Questions
Select the best answer.
1. What is the purpose of taking a radial pulse?
- To detect changes in the heart
- To see if the person has good circulation
- To assess the number of heartbeats in 1 minute
- To determine the force of the blood against the artery walls
Select the best answer.
2. In an adult, which pulse requires you to notify the nurse at once?
- A strong pulse at 80 beats per minute
- A steady pulse at 94 beats per minute
- A regular pulse at 68 beats per minute
- An irregular pulse at 56 beats per minute
Select the best answer.
3. In an adult, what term describes a radial pulse above 100 beats per minute?
Select the best answer.
4. Which action is a correct method for taking a radial pulse?
- Place your thumb over the groove along the thumb side of the person’s wrist
- Place your index and middle fingertips over the thumb side of the person’s wrist
- Place two or three fingers over the radial artery on the inside of the person’s elbow
- Place a stethoscope over the left side of the chest to the left of the person’s sternum
Select the best answer.
5. If a person’s pulse is irregular, how should you determine the pulse rate?
- Count for 15 seconds and multiply by 4
- Count for 20 seconds and multiply by 3
- Count for 30 seconds and multiply by 2
- Count for 1 full minute
