• Body Temperature Measurement: Select an appropriate measurement method according to the patient’s condition, such as axillary, oral, or rectal measurement. For axillary measurement, keep the thermometer in close contact with the skin for 5 – 10 minutes. For oral measurement, place the thermometer under the tongue for 3 – 5 minutes. For rectal measurement, insert the thermometer 3 – 4 cm into the rectum and take it out for reading after about 3 minutes. Check the integrity and accuracy of the thermometer before and after measurement.

• Pulse Measurement: Usually, use the fingertips of the index finger, middle finger, and ring finger to press on the radial artery at the patient’s wrist, and count the number of pulses in 1 minute. At the same time, pay attention to the rhythm, strength, and other conditions of the pulse.

• Respiration Measurement: Observe the rise and fall of the patient’s chest or abdomen. One rise and fall counts as one breath. Count for 1 minute. Pay attention to the frequency, depth, rhythm of breathing, and the presence of any abnormal breath sounds.
