What is the appropriate instruction to give a patient before taking a lateral lumbar X-ray?

When preparing a patient for a lateral lumbar X-ray, the correct instruction is to encourage the patient to take a breath in, then exhale, and hold their breath just as the exposure is made. This instruction is essential because holding the breath helps to minimize motion during the imaging process, which can lead to clearer images. It’s crucial for the patient to exhale and hold their breath instead of inhaling and holding, as this can prevent respiratory motion artifacts that may distort the X-ray image.

The sequence of breathing ensures that the diaphragm is in a neutral position, providing the best possible view of the lumbar region. This method helps to achieve optimal image quality while reducing the likelihood of repeat exposures due to poor image clarity. Additionally, it ensures patient safety and comfort by preventing unnecessary stress from prolonged breath-holding.
