During which of the following activities is it necessary for a medical assistant to use personal protective equipment (PPE)?

Using personal protective equipment (PPE) is crucial during the administration of injections because it helps ensure the safety of both the patient and the healthcare provider. When a medical assistant administers injections, they may come into contact with bodily fluids, which can pose a risk of infection or transmission of infectious diseases. PPE, such as gloves, helps create a barrier against these fluids, protecting the provider from potential exposure to pathogens. In addition, wearing PPE helps maintain a sterile environment, reducing the risk of contamination and ensuring that injections are performed safely and effectively.

In contrast, activities like scheduling appointments, taking patient temperatures, and filing medical records do not typically involve exposure to blood or bodily fluids, which is why PPE is not necessary in those scenarios. These tasks primarily involve administrative or non-invasive procedures where the risk of transmission is significantly lower.
