EKG 3&4

QuestionAnswer
The Einthoven triangle is formed by the following three limb leads: right arm, left arm, left leg.
Unipolar leads include all the lead types except: standard leads.
To obtain a 12-lead ECG tracing, you must apply how many lead wires and electrodes to the patient? 10
The leads that make up a 12-lead ECG consist of: 3 standard, 3 augmented, and 6 chest leads.
Signal processing, which occurs inside the ECG machine, amplifies the electrical impulse.
The gain control is normally set at: 10 mm/mV.
Often it is difficult to read the ECG tracing if a patient's heart rate is fast. Where should you set the speed control to be able to interpret the ECG tracing more easily? 50 mm/sec
The usual setting for the artifact filter is: 40 to 150 Hz.
You are preparing to conduct a 12-lead ECG on a patient. As you are gathering your supplies, you notice that five of the electrodes are made by one company and the other five electrodes are made by another company. What is your next step? Find a complete set of 10 electrodes that are the same.
Which type of electrode is preferred for use in a hospital or acute care setting? Silver electrodes
The ECG graph paper represents time horizontally and voltage vertically. What time and voltage are represented by one large box? 0.20 second and 0.5 mV
You are performing a 12-lead ECG on a hospital patient using a portable ECG machine on a cart. As you are conducting the ECG, a red line appears at the bottom of the ECG graph paper. What should you do? Continue the ECG, but remember to replace the paper before performing the next ECG.
Which of the following is an advantage of using dot matrix paper instead of the standard grid paper? Dot matrix paper produces sharper photocopies than standard grid paper.
Which of the following substances can accidentally erase an ECG tracing? Plastic
Which one of these is not a commonly used method to calculate heart rates? 1 minute method
When estimating the heart rate with the 6-second method, you locate 6 seconds on a rhythm strip, count the number of complexes, and multiply by: 10
To perform an ECG with accuracy, the best source to obtain specific information about the machine you are using is to consult: the manufacturer's instructions.
How many leads does a multichannel recorder monitor at one time? 12
Which type of electrode is most commonly used to perform an ECG? Disposable
When serial ECGs are performed on a patient, which of the following guidelines should be followed to ensure accurate results? The electrode placement must be the same for each ECG.
How long must the ECG tracing be maintained as part of a patient's medical record? 7 years
Unwanted marks on an ECG tracing that are not related to the heart's electrical activity are known as: artifact.
The ECG waveform is indicative of: how the heart is functioning electrically.
Which rib is located next to the angle of Louis? Second rib
The patient has a cast on his lower left leg. The limb electrode placement should be: at equal levels on the thighs.
What is the difference between continuous cardiac monitoring and a routine ECG? Only three electrodes are used.
The standardization mark on a manual ECG machine should be inserted: between the T wave of one complex and the P wave of the next.
Which of the following is not commonly performed as part of routine maintenance of an ECG machine? Sterilizing the cables
