Finding the Error Activity: Tympanic Temperature
Which is the correct technique for measuring the tympanic temperature?
Rectal Temperature
The normal rectal temperature is usually 1ºC higher than oral temperature (OER #1). A rectal thermometer has a red end to distinguish it from an oral/axillary thermometer. A rectal thermometer is shown in Figure 2.7. Technique First, ensure the client’s privacy. Wash your hands and put on gloves. For infants, lie them down in a supine Read more »
Axillary Temperature
The normal axillary temperature may be as much as 1ºC lower than the oral temperature (OER #1). An axillary thermometer is the same electronic device as an oral thermometer, and both have a blue end. Technique Remove the probe from the device and place a probe cover (from the box) on the thermometer without touching Read more »
Tympanic Temperature
The normal tympanic temperature is usually 0.3–0.6°C higher than an oral temperature (OER #1). It is accurate because the tympanic membrane shares the same vascular artery that perfuses the hypothalamus (OER #1). A tympanic thermometer is shown in Figure 2.4. Technique Remove the tympanic thermometer from the casing and place a probe cover (from the Read more »
Oral Temperature
The normal oral temperature is 35.8–37.3ºC (OER #1) or 96.4–99.1ºF. Oral temperature measurement is common and reliable because it is close to the sublingual artery. An oral thermometer is shown in Figure 2.2. The device has blue colouring, indicating that it is an oral or axillary thermometer as opposed to a rectal thermometer, which has Read more »
Methods of Measurement
Methods of measuring a client’s body temperature vary based on developmental age, cognitive functioning, level of consciousness, state of health, safety, and agency/unit policy. The healthcare provider chooses the best method after considering client safety, accuracy, and least invasiveness, all contingent on the client’s health and illness state. The most accurate way to measure core Read more »
Why is Temperature Measured?
Healthcare providers measure a client’s temperature because it can give information about their state of health and influence clinical decisions. Accurate measurements and interpretation are vital so that hyperthermia and hypothermia can be identified and appropriate interventions determined. Hyperthermia refers to an elevated body temperature. It can be related to an internal or external source. External Read more »
General Points to Consider in Vital Sign Measurement
Therapeutic Environment and Informed Consent It is important to seek informed consent while creating a therapeutic and safe environment during all encounters with clients. You will usually begin by introducing yourself by name and designation so the client knows who you are. Next, explain what you are going to do and always ask permission to Read more »
Finding the Error Activity
Now you have an opportunity to find errors in measurement techniques. The first activity involves watching a short film clip. What error in technique is this healthcare provider making while measuring oxygen saturation in Film clip 4.1?

Oxygen Saturation Technique
Technique The pulse oximeter probe is clipped onto or taped around a client’s finger, as shown in Figure 4.4. The device displays an oxygen saturation level and a pulse within a few seconds. Palpate the client’s radial pulse (taken for 30 seconds if regular and one minute if irregular) while the oximeter is attached to Read more »
