A medical assistant should take which of the following actions when placing electrodes on a patient for an EKG?
Place the arm electrodes facing downward.
Place the electrodes over bony prominences when possible.
Place the leg electrodes downward.
Place the chest electrodes in a straight line just below the nipple.
The Correct Answer is A
A. Place the arm electrodes facing downward. The arm electrodes should be placed with the tabs facing downward to reduce the risk of artifacts on the EKG tracing caused by movement or improper lead contact.
B. Place the electrodes over bony prominences when possible. Electrodes should not be placed over bony prominences, as this can interfere with the accuracy of the EKG reading. Instead, they should be placed on soft tissue.
C. Place the leg electrodes downward. Leg electrodes should also be placed with the tabs facing downward to prevent artifacts, similar to the arm electrodes.
D. Place the chest electrodes in a straight line just below the nipple. Chest electrodes should be placed according to specific anatomical landmarks, not in a straight line, to ensure accurate heart rhythm tracing.

Correct Answer is D
Explanation
A. Alcohol-based sanitizer: Alcohol-based sanitizers are effective for hand hygiene when there is no visible dirt or grease. They are generally used for routine hand antisepsis in situations where hands are not visibly soiled. For procedures involving body fluids, if hands are visibly soiled, traditional handwashing with soap and water is preferred.
B. Disinfectant scrub: Disinfectant scrubs are generally used for cleaning surfaces and are not appropriate for personal hand hygiene.
C. Antiseptic solution: Antiseptic solutions are used for cleaning skin before injections or procedures, not typically for hand hygiene.
D. Liquid soap: Liquid soap is suitable for handwashing, especially when hands are visibly soiled or after exposure to body fluids. In the context of body fluids, soap and water would be preferable to ensure effective removal of contaminants.
Correct Answer is B
Explanation
A. Ask the laboratory to send a link to an electronic version of the patient's report: The laboratory is not responsible for providing electronic versions of reports if paper reports are already received.
B. Scan the report into the patient's electronic health record (EHR): Scanning the report into the EHR ensures that the patient’s records are complete and accessible within the system.
C. Document that the results were delivered to the office in the patient's electronic health record (EHR): While documenting receipt is important, it does not substitute for the actual entry of the report into the EHR.
D. Sign their initials and place in the "to be filed" bin: Simply filing the report without scanning it into the EHR means the information is not integrated into the patient's digital health record.
