Which of the following laboratory sections performs CBC and erythrocyte sedimentation rate?

A. Alternating current (AC) interference: AC interference is caused by electrical equipment near the EKG machine and appears as uniform, small, rapid spikes. It is not caused by patient movement.
B. Arrhythmia: An arrhythmia refers to an abnormal heart rhythm and is related to cardiac function, not patient movement.
C. Somatic tremor: Somatic tremor is caused by voluntary or involuntary muscle movement, such as a patient moving their arm, which creates artifact on the EKG tracing that appears as irregular, erratic spikes.
D. Interrupted baseline: An interrupted baseline occurs when the electrical connection is lost, often due to a lead falling off, not due to patient movement.

A. Perform a sterile hand scrub: While sterile technique is important in many procedures, a sterile hand scrub is not specifically necessary for suture removal.
B. Lift the knot toward the wound: Lifting the knot towards the wound helps to ease the removal of the suture by reducing tension on the skin, making the procedure easier and less painful.
C. Begin cutting the sutures in the middle of the wound: Sutures should be cut close to the skin, not in the middle, to ensure proper removal and avoid causing unnecessary trauma to the wound.
D. Clean the wound with a disinfectant: Cleaning the wound with a disinfectant is not necessary before suture removal and might irritate the wound. Instead, the area should be cleaned after suture removal if needed.
