Final answer:
Placing pads directly over an implanted medical device could cause it to malfunction, potentially leading to incorrect device operation such as in the case of pacemakers or defibrillators. Additionally, the existence of biofilms on medical devices can lead to stubborn infections, highlighting the need for cautious interaction with such devices.
Step-by-step explanation:
If you place pads directly over an implanted medical device, the implanted medical device may malfunction or be adversely affected. The reason behind this is that the electrical current or pressure from the pads could interfere with the proper functioning of the device. For example, in the case of a pacemaker or defibrillator, placing pads directly on top of where the device is implanted can lead to incorrect sensing or therapy delivery.
Moreover, medical devices such as catheters can become contaminated when they come in contact with external factors. This can lead to the formation of biofilms, where Staphylococcus aureus bacteria and other microorganisms create layers of extracellular substrate, as indicated by the electron micrograph in the figure described. These biofilms are incredibly problematic because they are difficult to remove and can cause infections. Although the biofilm issue does not directly relate to the placement of pads, it demonstrates the importance of maintaining a sterile environment around any implanted medical device.
