What types of atrial arrhythmias are characterized by extremely rapid incomplete contractions?
- ANS Atrial Fibrillation (A-Fib)
How many leads are recorded on the standard electrocardiogram? - ANS 12 leads (6 limb
leads, 6 chest leads)
What are the standard bipolar leads in an electrocardiogram? - ANS Leads I, II, III
What are the augmented unipolar leads in an electrocardiogram? - ANS Leads aVR, aVL, aVF
What are the chest (precordial) leads in an electrocardiogram? - ANS Leads V1-V6
What is the name of the body's natural pacemaker? - ANS Sinoatrial (SA) node
Why should the ECG tracing be performed in a quiet, warm exam room? - ANS To minimize
artifacts from external electrical noise and patient movement

, What indicates ventricular depolarization? - ANS The electrical event where positively
charged ions rush into ventricular muscle cells, triggering muscle contraction
What is an electrocardiogram used for? - ANS Diagnosing heart problems, checking heart
rhythm, assessing heart structure, monitoring treatment, and screening
What bandage wrapping technique is used on a joint that requires movement? - ANS Figure-
of-eight bandage
What is required when labeling packages for autoclaving? - ANS Name of the item, date of
sterilization, initials of the preparer, sterilizer number, and expiration date
What is the recommended temperature for effective sterilization in an autoclave? -
ANS 250°F to 270°F (121°C to 132°C)
What should a patient observe for signs of infection? - ANS Jagged edges, tenderness,
purulent drainage, fever, red streaks, and bleeding that does not stop
What is the first step when setting up a sterile field? - ANS Wash your hands
What should be checked before opening a sterile package? - ANS Ensure the package is dry,
intact, and not expired
What is an example of a closed wound? - ANS Bruise (contusion), hematoma, sprain, strain,
closed fracture, crush injury
What are the basic rules for cleaning instruments? - ANS Clean immediately after use, use
appropriate cleaning agents, rinse thoroughly
