The practical nurse (PN) notices that one of the unlicensed assistive personnel (UAP) working in the long- term care facility consistently records subnormal temperatures when using the thermometer. Which action should the PN take first?

When the practical nurse (PN) notices that one of the unlicensed assistive personnel (UAP) consistently records subnormal temperatures when using the thermometer, the first action the PN should take is to observe how the UAP obtains temperatures. This allows the PN to directly assess the UAP's technique and determine if any errors or inaccuracies are occurring during temperature measurement. By observing the process, the PN can identify any potential issues, such as incorrect placement of the thermometer or improper technique, and provide appropriate guidance and education.
