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: Demonstrating proper technique is useful after identifying the source of the problem. However, before instructing, the PN must first assess whether the issue lies with the UAP’s technique, the thermometer, or both. B. Return the thermometer for recalibration: Sending the thermometer for recalibration may be unnecessary unless the PN confirms that incorrect readings are due to equipment malfunction. It is more appropriate to verify the accuracy of the procedure before assuming the device is faulty. C. Observe how UAP obtains temperatures: Direct observation allows the PN to assess whether the UAP is using correct technique, such as proper ear positioning and seal. This helps determine if the subnormal readings result from user error or equipment issues, guiding appropriate corrective action. D. Show UAP how to chart temperatures: Documentation accuracy is important, but charting technique is not the cause of consistently abnormal readings. The PN must first identify and correct the underlying problem in the temperature-taking process.
