What is the recommended patient position for taking a rectal temperature?

• A. Supine position
• B. Prone position
• C. Left side-lying Sim's position
• D. Sitting upright

Answer: (D)

Taking a rectal temperature is best done with the patient in the left side-lying Sims position. This posture exposes the anal area for easy, stable access while helping the patient relax and reducing the risk of injury during insertion. It also aligns the rectal canal to allow safe, controlled placement of the thermometer. Other positions—lying on the back, lying face down, or sitting upright—make access more awkward, can be less comfortable or stable, and may compromise the accuracy and safety of the measurement.
