In which position would a patient be placed for a rectal exam?

For a rectal exam, the appropriate position for the patient is Sims' position. This lateral position involves the patient lying on their left side, with the right knee bent and brought up toward the chest. This position is advantageous for several reasons: it allows for easier access to the rectal area while providing comfort and maintaining the patient's dignity.

Positioning the patient in Sims' position also ensures that gravity assists in the examination, allowing for better visualization and access, which is crucial for a thorough assessment. Additionally, this position can help to relax the anal sphincter and make the examination less uncomfortable for the patient.

The other positions listed serve different purposes; Fowler's position is often used for patients who have difficulty breathing or need to be seated for certain examinations. Smith's position is not a standard term widely recognized in medical practice. Lithotomy position, commonly used for gynecological examinations, places the patient on their back with legs in stirrups, which is not suitable for a rectal exam.
