Question: how to check axillary temperature with mercury thermometer?
Answer: Use a rectal or oral thermometer.
Clean the thermometer with cool, soapy water and rinse.
Shake the thermometer so that the mercury inside goes below 36°C (96.8°F).
Place the tip of the thermometer in the centre of the armpit.
