Final answer:
The EKG machine can pose a slight risk of injury to patients, mainly due to the adhesive electrodes causing skin irritation or burns. Extra caution should be taken for patients with pacemakers or other implanted devices.
Step-by-step explanation:
While the EKG machine is generally safe, there is a slight risk of injury for the patients. The main risk is from skin irritation or burns caused by the adhesive electrodes that are attached to the patient's skin during the procedure. These risks can be minimized by ensuring that the electrodes are properly placed and not left on the skin for too long. Additionally, patients with certain medical conditions or implanted devices like pacemakers should be cautious when undergoing an EKG to avoid any interference or harm to those devices.
