A fever is a common symptom of an illness, and measuring body temperature is an essential part of monitoring an individual’s health.

It is important to get an accurate reading of body temperature, or else it could lead to improper diagnosis and treatment. The most accurate way to measure body temperature is to use a thermometer. However, it is necessary to follow specific guidelines when taking someone’s temperature with a thermometer to ensure accurate readings.

Choose the right thermometer

When getting a thermometer, it is essential to choose the right one for the type of measurement that you want to take. Different types of thermometers are available on the market, including oral, ear, forehead, and rectal.

It is essential to pick one that suits you best, and that will give you an accurate reading. Oral thermometers are the most common type and are easy to use by placing them under the tongue. Ear and forehead thermometers are also widely used and non-invasive, but they might give different readings depending on environmental situations.

Prepare the thermometer

Before taking someone’s temperature, you need to prepare the thermometer to get accurate readings. Wash your hands to avoid transferring germs, and make sure that you clean the thermometer according to the instructions.

Once the thermometer is clean, you can turn it on and ensure that it is working correctly. Make sure to read the instructions, especially if you are using a new type of thermometer, to avoid inaccurate readings.

Choose the right location

The location where you take someone’s temperature with a thermometer can determine the accuracy of the reading. Different types of thermometers require different locations. Oral thermometers need to be placed under the tongue.

Ear thermometers need to be placed in the ear canal, and forehead thermometers need to be placed on the forehead, away from hair and brows. Rectal thermometers need to be inserted into the rectum. Choosing the right location can ensure accurate readings.

Avoid physical activity and drinks

Physical activity and drinking cold or hot drinks can affect body temperature readings. Physical activity can cause sweating, leading to inaccurate readings.

Having hot or cold drinks can cause a sudden change in the body temperature, leading to wrong readings. If you or the person whose temperature you are measuring has been physically active or had a drink, it is advisable to wait for at least 20 minutes before taking the temperature.

Place the thermometer correctly

Putting the thermometer in the right place is crucial to getting an accurate reading. The thermometer should be placed in the location specified by the instructions for the type of thermometer being used.

Once the thermometer is placed in the right location, hold it in place according to the instructions, and wait for the beep or indication that the reading is complete. Avoid removing the thermometer too soon or moving it around as it can affect the readings.

Read and record the temperature

Once the thermometer has completed the reading, read and record the temperature. Different types of thermometers have different ways of displaying readings.

For instance, digital thermometers display temperature readings on a screen while mercury thermometers have engraved scales. Make sure you know how to read the thermometer and record the temperature accurately.

Clean the thermometer

Cleaning the thermometer after use is important to avoid the spread of germs. Follow the instructions to clean and disinfect the thermometer after taking a measurement.

Cleaning the thermometer after use also ensures that it is ready for the next use without affecting accuracy.

Take temperature regularly

Taking temperature regularly can help in monitoring an individual’s health. Keeping track of the temperature can help to detect if the person’s illness is improving, deteriorating, or staying the same.

Depending on the severity of the sickness, temperature can be monitored at different intervals – hourly, daily or weekly – or as directed by a doctor.

Conclusion

A thermometer is an essential tool for measuring body temperature accurately. However, it is necessary to follow certain guidelines to ensure accurate readings. Choose the right thermometer and place it in the right location.

Avoid physical activity and drinking beverages before taking someone’s temperature, and place the thermometer correctly. Read and record the temperature, clean the thermometer after use, and take a temperature regularly as guided by a medical professional. Following these guidelines can ensure that you get an accurate fever reading with a thermometer.
