Question 1: To minimize artifact, what must be done?
Answer:
Attach electrode patches securely and tell the patient not to move during the EKG Question 2: The most common cause for the P wave, QRS complex, and T wave to be inverted in Lead I is
Answer:
Incorrect lead placement Question 3: Your patient for a 12-lead EKG has no legs as a result of bilateral amputations.Where should you put the leg electrode?
Answer:
On the lower abdomen above where the legs would be Question 4: If there is artifact in leads II, III, and aVF, on which limb(s) would you expect to find the cause of the artifact?
Answer:
Left leg
Question 5: On your patient's 12-lead EKG, lead I's waves and complexes are completely negative. AVR's waves and complexes are completely positive. The most likely cause of this is
Answer:
Right and left arm leads inadvertently reversed Question 6: If artifact is seen in leads I, III, and aVL, the problem is on which limb?
Answer:
Left arm
Question 7: Microshock is different from macroshock in that microshock is
Answer:
A lower-voltage electrical shock
Question 8: A digital converter on the EKG machine
Answer:
Converts the analog signal to a digital one
Question 9: Small adhesive patches with conductive gel on the skin side are
Answer:
Electrodes Question 10: Electrical shock is LEAST likely to be caused by which of the following?
Answer:
Properly maintained EKG machine Question 11: Your patient is having chills. What kind of artifact can this produce?
Answer:
Somatic Tremors Question 12: The artifact cause by the jiggling of wires doing tooth-brushing is called
Answer:
"Toothbrush Tachycardia"
Question 13: If your patient's cardiac rhythm is life-threatening, your FIRST action should be to
Answer:
Check the patient- assess vital signs and see how he/she feels
Question 14: Electrically speaking, the heart is
Answer:
transmitter
Question 15: Muscle artifact can be minimized by monitoring the patient in lead
Answer:
V1 or MCL1 Question 16: Your patient is smiling and visiting family, but the cardiac monitor shows that the patient's heart has completely stopped. The rhythm on the monitor is thus
Answer:
Artifact
Question 17: Somatic tremor artifact is commonly caused by
Answer:
Patient movement Question 18: The most important benefit of a three-channel recorder when doing a 12-lead EKG is
Answer:
All leads can be recorded simultaneously
Question 19: Normal paper speed for printing out the EKG is
Answer:
25 mm/sec.
Question 20: Muscle artifact is seen most often in
Answer:
The frontal leads
Question 21: A patient is short of breath and his nurse tells you he must have the head of the bed (HOB) at 90 degrees for his 12-Lead EKG. You
Answer:
Do the EKG at 90 degrees and document this position on the EKG.Question 22: If artifact is present in lead I, II, and AVR, the most likely source of the artifact is on the
Answer:
Right arm Question 23: Some modern EKG machines are Bluetooth-capable, allowing EMS workers to
Answer:
Transmit the EKG to the nearest hospital so workers can prepare for the patient's arrival
Question 24: Sixty-cycle interference is commonly caused by
Answer:
Electrical interference
Question 25: The "gain" setting on the EKG machine is concerned with
Answer:
The amplitude of the waves and complexes
