When positioning a patient for a bone density scan, their shoulders should be squared with which part of the body?

• A. Head
• B. Pelvis
• C. Feet
• D. Knees

Answer: (B)

In a bone density scan, proper patient positioning is crucial for obtaining accurate results. When the patient's shoulders are squared with the pelvis, it ensures that the entire body is aligned correctly for the scan. This alignment reduces the chances of rotation or misalignment, which can affect the measurements obtained during the scan. The pelvis serves as a central point for anatomical alignment in many types of imaging, including bone density assessments. By positioning the shoulders parallel to the pelvis, it helps to ensure that the regions of interest, typically the lumbar spine or hip, are captured accurately without distortions. This alignment is important for the reproducibility of the scan results, allowing for consistent measurements over time, which is essential for tracking changes in bone density. Positioning the shoulders with respect to other body parts, like the head, feet, or knees, would not provide the same level of alignment with the pelvis and may lead to inaccuracies in the scan results. Thus, having the shoulders squared with the pelvis is the optimal choice for ensuring precise and reliable bone density measurements.
