Clinical Medical Assistant Certification Exam Practice Question
A medical assistant is performing an ECG. Following the procedure, the ECG lead wires will need to be cleaned to prevent which of the following types of transmission?
Correct Answer: A
Rationale: Cleaning ECG lead wires is essential to prevent fomite transmission, which involves the spread of pathogens via contaminated surfaces or objects. Since lead wires come into direct contact with patients, they can harbor infectious agents that may be transferred to others.
Vector-borne transmission (B) requires a living organism, such as insects, to spread disease, which is not applicable here. Airborne transmission (C) involves pathogens that remain suspended in the air, while bloodborne transmission (D) pertains to pathogens found in blood, neither of which relates to the cleaning of ECG equipment. Lastly, droplet transmission (E) involves larger respiratory droplets, not surfaces. Thus, fomite transmission is the primary concern in this scenario.
