Thermometers and Temperature Scales

Any physical property that depends consistently and reproducibly on temperature can be used as the basis of a thermometer. For example, volume increases with temperature for most substances. This property is the basis for the common alcohol thermometer and the original mercury thermometers. Other properties used to measure temperature include electrical resistance, color, and the emission of infrared radiation. As many physical properties depend on temperature, the variety of thermometers is...

Gas Thermometers and the Kelvin Scale

The definition of temperature in terms of molecular motion suggests that there should be a lowest possible temperature, where the average kinetic energy of molecules is zero (or the minimum allowed by quantum mechanics). Experiments confirm the existence of such a temperature, called absolute zero. An absolute temperature scale is one whose zero point is absolute zero. Such scales are convenient in science because several physical quantities, such as the volume of an ideal gas, are directly...

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT The purpose of peripheral intravenous catheter (PIV) insertion is to infuse medications, perform intravenous (IV) fluid therapy, or inject radioactive tracers for special examination procedures. Placing a PIV is an invasive procedure and requires the use of an aseptic, no-touch technique. Common IV venipuncture sites are the arms and hands in adults and the feet in children. According to...

FAQs
Temperature sensing is not instantaneous: the probe detects heat as it approaches the temperature of surrounding tissue or body fluids. If it is removed before stabilization, the displayed value may not represent the sampled site. Allowing sufficient time for equilibration therefore improves measurement reliability and helps clinicians interpret changes in physiological status with greater confidence.
Site selection determines what the measurement represents. An appropriately positioned probe can assess core temperature or a more localized temperature, depending on the designated body site and clinical purpose. Placement that does not provide adequate contact with the intended tissue or fluid can reduce accuracy, so the site and positioning must match the measurement goal.
Contact allows heat to pass from tissue or body fluids to the temperature-sensing device. Poor contact or incorrect placement can prevent the probe from reaching a representative thermal condition, even when the device itself is functioning. Checking contact and waiting for stabilization are consequently central to obtaining a dependable value rather than a misleading transient reading.
Reliable insertion starts with choosing the designated site and device for the clinical purpose, then placing the probe correctly with adequate contact. The clinician should allow sufficient time for the reading to stabilize before recording it. Patient comfort, hygiene, and infection-control measures also remain part of the technique, because measurement quality and safe clinical practice must be addressed together.
Different sites are selected according to the device and the clinical purpose of the measurement. Oral and rectal insertion are examples of site-specific approaches, while another designated site may be appropriate when the intended measurement differs. The choice affects whether the result is interpreted as core or local temperature, so site selection should be deliberate rather than interchangeable.
An accurately obtained temperature can help identify fever or hypothermia and can reveal changes during monitoring or treatment. Its clinical value depends on trustworthy placement, contact, and stabilization, because an unreliable measurement may obscure a physiological change. Consistent attention to these conditions supports assessment of the patient's status and interpretation of temperature changes during care.
