What is the designated population that should never hold patients during an exam?

The designated population that should never hold patients during a radiographic exam is pregnant women. This is primarily due to the potential risks that ionizing radiation can pose to the developing fetus. During radiographic procedures, exposure to radiation, even at low levels, can lead to harmful effects including developmental issues or increased risk of cancer later in life for the unborn child.

In radiography, it is critical to minimize any unnecessary exposure to radiation for both patients and those who assist in the procedures. Since pregnant women are at a stage where the safety of the fetus is paramount, they are advised against holding patients, as this could inadvertently expose them to radiation.

Other populations, such as children and senior citizens, also require special consideration due to factors like sensitivity to radiation and the ability to remain still during procedures. However, the specific concern for the developing fetus makes pregnant women the designated group that should be completely excluded from holding patients during examinations.
