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 a tympanic thermometer. Which action should the PN take first?

A. Demonstrate how to use the equipment: Not the first step-observe current technique before teaching. B. Return the thermometer for recalibration: May be necessary but only after confirming incorrect readings are not due to user error. C. Show UAP how to chart temperatures: Not relevant to low readings; focuses on documentation rather than accuracy. D. Observe how UAP obtains temperatures: First step-assess technique to determine if error is due to improper use or faulty equipment.
