If a client recently smoked a cigarette, how long should a psychiatric technician wait before taking their oral temperature?

The appropriate waiting period before taking an oral temperature after a client has smoked a cigarette is 15 minutes. This timeframe is recommended because smoking can significantly affect oral temperature readings. Nicotine and the heat from the cigarette can temporarily elevate body temperature, leading to inaccurate readings if taken immediately afterward.

By waiting 15 minutes, the technician allows enough time for the immediate effects of smoking to dissipate, ensuring that the temperature taken reflects the client's true physiological state rather than the transient influence of smoking. This practice aligns with standard procedures for obtaining accurate temperature readings and is essential in clinical settings to provide relevant data for assessments and interventions.
