d) Use an oral thermometer for rectal temperature

Answer 1

The correct guidelines for checking rectal temperature are lubricating the thermometer, inserting it 1-2 inches into the rectum, and holding in place for 2-3 minutes, using a special rectal thermometer.

Step-by-step explanation:

When checking a rectal temperature, there are specific guidelines to ensure accuracy and safety. Remember to:

• Lubricate the thermometer before use to minimize discomfort and facilitate easier insertion.
• Insert the thermometer 1-2 inches into the rectum to ensure it is in contact with the mucous membrane, where it can gauge the core body temperature effectively.
• Once inserted, hold the thermometer in place for 2-3 minutes to obtain a reliable reading. Digital thermometers may signal earlier when the reading is complete.

It's important to note that a special rectal thermometer is necessary for this purpose, as oral thermometers are not designed for rectal use and can give inaccurate readings or become damaged.
