Final answer:
The placement of an implanted port considers site suitability and device type. The removal in Barbara's case was due to symptoms suggesting a localized infection, likely from biofilm growth.
Step-by-step explanation:
When considering the placement of an implanted port, two key things are taken into account. Firstly, the suitability of the site for the implant, which must facilitate ease of access for chemotherapy, minimize the risk of infection, and ensure patient comfort. Secondly, the type of device used must be appropriate for the patient's condition and the type of treatment they will be receiving.
In Barbara's case, given her symptoms such as the localized infection at the catheter site indicated by redness and warmth, along with a fever, her physician decided to remove the implanted port and catheter. These signs and symptoms suggest that a localized infection could be present, likely arising from the growth of microorganisms forming a biofilm on the catheter. In managing such infections, physicians aim for the prompt removal of the device to prevent further complications.
