Which of the following should appear on an EKG tracing if a patient's arm moved during recording?
Alternating current (AC) interference
Arrhythmia
Somatic tremor
Interrupted baseline
The Correct Answer is C
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.

Correct Answer is D
Explanation
A. Remove dental plates before the procedure. Dental plates do not interfere with a mammogram, so removing them is unnecessary.
B. Do not eat or drink anything for 4 hr before the procedure. There are no dietary restrictions required before a mammogram, so this instruction is not necessary.
C. An IV will be started before the procedure. An IV is not required for a mammogram, which is a non-invasive imaging procedure.
D. Do not apply any deodorant before the procedure. Patients are advised not to apply deodorant, lotions, or powders before a mammogram because these products can show up as artifacts on the mammogram images, potentially leading to misinterpretation.
Correct Answer is C
Explanation
A. Glutaraldehyde: Glutaraldehyde is used for high-level disinfection of medical equipment, not for cleaning blood spills.
B. Isopropyl alcohol: While isopropyl alcohol is used for disinfection, it is not the preferred choice for blood spills due to its lower efficacy against certain pathogens.
C. Bleach: A bleach solution is effective for disinfecting surfaces contaminated with blood, as it is effective against a broad range of pathogens, including bloodborne viruses.
D. Iodine compounds: Iodine is used for antiseptic purposes on skin but is not ideal for disinfecting blood spills on surfaces.
