Final answer:
When taking an adult patient's temperature rectally, it is important to insert the probe so that you are aiming at the patient's pelvic area, dip the probe 1-1.5 inches into a tube of lubricant, insert the probe about an inch and a half into the patient's anus (Options 2, 3, and 4).
Step-by-step explanation:
It is important to follow specific procedures when taking an adult patient's temperature rectally. This is to ensure the process is done correctly and comfortably.
You should dip the probe about 1-1.5 inches into lubricant to minimize discomfort during insertion.
It is recommended to insert the probe about an inch and a half into the patient's anus, and always aim towards the patient's pelvic area to follow the natural curve of the rectum.
Rotating the probe is not typically advised, as it could cause discomfort or injury.
Digital medical thermometers work by measuring the resistance of a semiconductor device called a thermistor. A specific calculation can be made to determine a patient's body temperature based on the resistance measured.
If the thermistor's resistance at the patient's temperature is 82.0% of its value at 37.0°C (normal body temperature), calculations can be performed to find the actual body temperature.
Infrared technology has also advanced temperature-taking methods. Infrared ear thermometers, for example, use energy emission measurement to gauge temperature.
These devices are particularly beneficial in fast-paced or sensitive healthcare settings because they are quick, contactless, and help prevent the spread of infection.
Hence, the correct answers are Options 2, 3, and 4.
