A medical assistant fails to accurately document a patient's reported adverse reactions after an office procedure. This is an example of which of the following?

A. Thoracentesis: Thoracentesis is a procedure to remove fluid from the space between the lungs and the chest wall; it is not a reconstruction.
B. Rhinoplasty: Rhinoplasty is a surgical reconstruction of the nose, often performed for cosmetic or functional reasons.
C. Appendectomy: Appendectomy is the surgical removal of the appendix, not a reconstructive surgery.
D. Colotomy: Colotomy is the surgical incision into the colon, not a reconstructive procedure.

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.
