What is the primary reason for using a bath thermometer for this patient?

• A. To ensure water temperature is below 102° F (38.8° C).
• B. To measure blood pressure.
• C. To monitor heart rate.
• D. To test water acidity.

Answer: (A)

Older adults have thinner skin and may not feel heat as quickly, so bathwater can cause burns before they realize it. A bath thermometer helps verify the water is at a safe temperature before immersion, reducing the risk of scalding. Keeping the water below about 102°F (38.8°C) makes bathing comfortable and safer. It isn’t used to measure blood pressure or heart rate, nor to test water acidity, which is why those other options aren’t appropriate. Use the thermometer to set the temperature, then adjust with cooler water as needed for safety.
