Certified Medical Assistant (CMA) Baseline Practice Test

To prepare a patient for a mole excision, it is essential to cleanse the site thoroughly to reduce the risk of infection and ensure a clear surgical field. Using surgical soap and an antiseptic is a critical step in this process, as it removes dirt, oils, and microbial flora from the skin. This preparation is crucial for maintaining a sterile environment, which helps in preventing complications during and after the procedure.

While marking the site with a pen is important for surgical accuracy, ensuring that the site is properly cleansed comes first to prioritize patient safety and minimize infection risks. Similarly, applying a bandage or using a cotton ball may occur after the procedure but is not a preparatory step before the excision. Therefore, the most appropriate action for the medical assistant to take in this scenario is to cleanse the site with surgical soap and an antiseptic.
