Question

A CNA needs to obtain a resident's oral temperature. The resident is drinking a cold cup of water. What should the CNA do?

1) Take the oral temperature immediately.
2) Wait until the next time the resident's oral temperature is ordered.
3) Wait approximately an hour before taking the resident's oral temperature.
4) Wait approximately 15 minutes before taking the resident's oral temperature.

Answer 1

A CNA should wait approximately 15 minutes before taking a resident's oral temperature if they are drinking a cold cup of water.

Step-by-step explanation:

When a CNA needs to obtain a resident's oral temperature and the resident is drinking a cold cup of water, the CNA should wait approximately 15 minutes before taking the resident's oral temperature. This is because drinking cold water can temporarily lower the temperature in the mouth. Waiting for 15 minutes allows the mouth temperature to return to its normal range. After 15 minutes, the CNA can take the oral temperature using a digital thermometer placed under the tongue.
