Vital Signs and Laboratory Reference Intervals
- Vital signs include temperature, pulse, respirations, blood pressure (BP), oxygen saturation (pulse oximetry), and pain assessment.
- Initial vital sign measurements provide baseline data and help identify changes in a client's health status.
- Some vital sign measurements (temperature, pulse, respirations, BP, pulse oximetry) may be delegated to assistive personnel (AP), but the nurse is responsible for interpreting the findings.
- The nurse collaborates with the primary health care provider (PHCP) to determine the frequency of vital sign assessment and makes independent decisions based on the client's status.
- The nurse documents vital signs and reports abnormal or unexpected findings to the PHCP.
- Vital signs are measured on initial contact with a client, during physical assessments, before and after invasive or surgical procedures, during medication administration if it affects cardiac, respiratory, or temperature control, and before, during, and after blood transfusions.
- Vital signs are checked whenever a client's condition changes or reports unusual feelings.
- Vital signs are checked with fever or known infection, every 2-4 hours.
Temperature
- Normal body temperature can range from 97.0° F (36.1° C) to 99.0° F (37.2° C) (according to WebMD, 2020).
- A fever is present when temperature is elevated, feels warm to touch, or report feeling feverish.
- A client might have a flushed face, glassy eyes, or chills with a fever.
- Some health care providers consider a fever when the temperature is 100.4° F (38° C) or higher.
- Common measurement sites are the mouth, rectum (unless contraindicated), axilla, ear, and forehead (temporal artery).
- Rectal temperatures are usually 1° F (0.5° C) higher and tympanic and axillary temperatures about 1° F (0.5° C) lower than oral temperature.
Pulse
- Average adult heart rate is 60 to 100 beats per minute.
- Pulse measurements can evaluate a client's tolerance to interventions like ambulation, bathing, and exercise.
- A Doppler ultrasound stethoscope is used to amplify pulse sounds when difficult to locate manually.
Respirations
- Respiration is the exchange of gases (atmosphere to blood and blood to cells).
- Normal adult respiratory rate is 12-20 breaths per minute.
- Respirations are affected by factors like exercise, pain, anxiety, smoking, and body position.
