What is the correct patient instruction before taking an imaging of the lumbosacral spot?

Before taking an imaging of the lumbosacral spot, it is crucial for the patient to remain still to ensure the clarity of the images captured. Deep breathing can help relax the patient and open up the thoracic cavity, providing a more stable and comfortable state during the procedure. However, once the imaging process begins, it's essential that the patient ceases any movement, including breathing, to avoid any blurring or artifacts in the x-ray.

In this context, the instruction to "remain still and breathe in deeply" emphasizes the need for stability during the imaging while promoting a state of relaxation through deep breathing. This practice not only enhances the integrity of the images but also contributes to patient comfort.

While the other options suggest different methods of breathing, they either encourage shallow breathing or in-progress inhalation or exhalation at the wrong time, which may compromise image quality. Therefore, the selected instruction aligns with best practices for obtaining clear and accurate imaging of the lumbosacral area.
