What should a client be instructed to remove before undergoing a chest x-ray?

Before undergoing a chest x-ray, clients are advised to remove metal necklaces because these can interfere with the quality of the imaging. Metal can create artifacts on the x-ray film, potentially obscuring important anatomical details that need to be evaluated by the radiologist. This ensures that the images obtained are clear and accurate, allowing for proper diagnosis and assessment of the client's chest health.

While contact lenses, makeup, and jewelry on the hands may have various considerations in a medical context, they do not typically pose a significant risk for obscuring the imaging process in the same way that metallic items like necklaces do. Thus, the focus on removing metal necklaces prior to the x-ray underscores the need for maintaining image clarity and diagnostic efficiency.
