8.3 Measurement Skills: Pulse, Respirations, and Output
Key Takeaways
- Measurement skills test both technique and accuracy; the candidate must obtain the value correctly and record or report it in the required form.
- Pulse measurement requires correct site, finger placement, timing, rhythm awareness, resident comfort, and a clear recorded rate.
- Respirations should be counted without coaching the resident to change breathing, because awareness can alter the rate.
- Urinary drainage output must be read at eye level, measured in the correct unit, and handled without contaminating the drainage system.
Measurements Must Be Real, Clean, and Recorded
Measurement skills look simple until test pressure begins. Counting a pulse, counting respirations, or measuring urinary drainage output requires accuracy, infection control, privacy, and correct recording. The nurse depends on these numbers to notice changes in condition. Guessing, rounding carelessly, using the wrong unit, or contaminating equipment can harm a resident even if the task seems small.
For pulse, the radial pulse at the wrist is commonly used when assigned. Position the resident comfortably, support the arm if needed, and use the pads of your first two or three fingers. Do not use your thumb because it has its own pulse. Press gently enough to feel the beat but not so hard that you block it. Count for the time required by the skill instructions or facility procedure. If the rhythm feels irregular, follow the testing instructions and report the irregularity as appropriate.
A pulse is more than a number. Notice whether it is regular or irregular, strong or weak, fast or slow compared with what you expected, and whether the resident has symptoms such as dizziness, shortness of breath, chest discomfort, unusual fatigue, or pale color. In the test, do not invent symptoms or overstep your role. In real care, report abnormal findings and resident complaints promptly.
Respirations should be counted by watching the rise and fall of the chest or abdomen. One rise and one fall count as one respiration. Many residents change their breathing if they know it is being counted, so you may keep your fingers near the pulse site and count respirations quietly after pulse measurement, depending on the assigned procedure. Do not tell the resident to breathe faster, slower, deeper, or normally unless the procedure specifically requires instruction. Your job is to observe the current rate.
Structured Aid: Measurement Accuracy Grid
| Skill | Clean technique | Accuracy point | Finish step |
|---|---|---|---|
| Pulse | Hand hygiene before and after, clean contact with resident | Use fingertips, correct site, correct timing, do not use thumb | Record rate and report concerns as directed |
| Respirations | Maintain resident comfort and privacy | Count one rise and fall as one breath without cueing breathing | Record rate and report difficulty breathing or unusual pattern |
| Urinary output | Wear gloves, avoid contaminating drain, keep bag below bladder | Drain into graduate if assigned, read at eye level, use mL | Empty or secure equipment as directed, remove gloves, hand hygiene, record output |
Urinary drainage output measures the amount of urine in a drainage bag. The drainage system must stay below the level of the bladder and off the floor. Tubing should not be kinked, pulled tight, or looped in a way that blocks urine flow. When emptying a drainage bag, wear gloves and keep the drain from touching the graduate, floor, bed, or your gloves if possible. If the drain becomes contaminated, follow facility policy and report as needed.
Read liquid output at eye level on a flat surface. The surface of liquid curves slightly; use the line at the bottom of the curve when reading a graduate. Record the amount in milliliters, often written as mL. Do not record ounces unless the assigned form asks for that unit. Do not estimate from across the room. A difference that looks small can matter when intake and output are being monitored.
Measurement skills often create silence, and silence can make candidates nervous. Use short, appropriate statements. For pulse, you might say, I am going to check your pulse at your wrist. For respirations, avoid announcing in a way that changes breathing if your procedure teaches a quiet count. For output, explain that you will empty and measure the drainage bag while maintaining privacy. You do not need to narrate every number while counting.
Avoid common test errors. Do not count respirations while talking to the resident. Do not let the resident's hand dangle unsupported if that makes the pulse hard to find. Do not place the drainage bag on the bed or raise it above bladder level. Do not touch the inside of the graduate. Do not forget to remove gloves and wash hands after handling urine. Do not leave the resident without call light and safe positioning.
Practice measurements with real timing. Use a watch with a second hand or approved timing device during practice. Count pulse and respirations on different people because rates vary. Practice reading water in a graduate at different levels, including awkward amounts like 175 mL or 450 mL. Say and write the final value clearly. The goal is to make accuracy ordinary under pressure.
A candidate is counting a resident's respirations after pulse. The resident asks what she is doing, and the candidate says, I am counting your breaths, so breathe normally and slowly. The resident immediately changes breathing pattern. What would have been a better approach?
While measuring urinary drainage bag output, a candidate drains urine into a graduate, places it on the bedside table, and reads the amount while standing above it. The meniscus is hard to see. What should the candidate do?
A candidate checks radial pulse using her thumb because it feels stronger than her fingertips. Why is this incorrect?
