NUR 213 Exam 2024 | Nursing 213 ExamUpdate 2024 Questions and Correct
Answers Rated A+
What is the inherent pacemaker of the heart? -ANSWER-SA node
(sino-atrial node) 60-100 per minute is normal pace
What does the P wave indicate? -ANSWER-Atrial depolarization, we
cannot for sure say that the atria contracted because you can have
the electricity without the pump (is there a pulse with that rhythm?)
What does the QRS wave indicate? -ANSWER-Ventricular
depolarization, at the same time the atria is re-polarizing. We cannot
for sure say that the ventricle contracted because you can have the
electricity without the pump (is there a pulse with that rhythm?)
What does the T wave indicate? -ANSWER-Ventricular re-polarization
What is the appropriate time measurement for the PR interval? -
ANSWER-0.12-0.2 seconds, 3-5 small boxes on graph paper
What is the appropriate time measurement for the QRS
interval? -ANSWER-Less than 0.12 seconds
What is the resting state for an ECG? -ANSWER-Isoelectric line
When you are feeling a pulse what are you feeling? -ANSWER-The
QRS, which is the ventricle depolarizing. You cannot feel the atria
depolarize because it doesn't have a strong enough beat
How long is each small box? -ANSWER-0.04 seconds
,What is the time measurement of one LARGE box on the EKG paper?
-ANSWER-0.2 seconds
How do you calculate heart rate? -ANSWER-Feel patients pulse,
count the R's in a six second strip and multiply by 10
What are the RULES for Normal Sinus Rhythm? -ANSWER-Rhythm
needs to be regular (measured R to R) and is either regular or
irregular, then Rate (60-100), then P-waves (do we have one for every
QRS and is their morphology the same and are they upright), PR
interval (measure from where the P wave leaves the isoelectric line
and stop measuring at the beginning of the QRS complex) it should be
0.12-0.2 seconds, then look at QRS and it should be less than 0.12
ECG labeled -ANSWER-
Positive deflection, negative deflection and biphasic deflection -
ANSWER-
Measurements for ECG -ANSWER-PR interval - .12 - .20 sec.
QRS complex - less than .10 seconds
P - P - Regular
R - R - Regular
Analyzing a rhythm strip step-by-step -ANSWER-1. Determine the
regularity of R waves
2. Calculate the heart rate
3. Identify and examine P waves
4. Measure the PR Interval
5. Measure the QRS complex
,Precise rate calculation for HR -ANSWER-Precise rate calculation
Count the number of small squares between two consecutive R waves
Divide the number of small squares into 1500 or use a conversion
chart
Only accurate for regular rhythms
Identifying and examine P waves -ANSWER-One P wave preceding
each QRS
All P waves identical in shape, size, and position
P to P interval should be regular
Examine the ST segment -ANSWER-Normal ST segment is flat and at
the isoelectric line
Elevation or depression measuring 1mm above or below is abnormal
Elevation = acute myocardial injury
Depression = myocardial ischemia, hypokalemia, digitalis
Assess the patient when using an ECG -ANSWER-Is there a PULSE
with that Rhythm???!!!
ALWAYS take a pulse before you treat a high or low alarm
False high alarms
False low alarms
Artifact- junk
Normal Sinus Rhythm (NSR) -ANSWER-Rhythm: Regular
Rate: 60 - 100
P waves: 1 P wave before each QRS, Normal in appearance
PR: .12 - .20 seconds
QRS: < .12 seconds
Sinus Tachycardia (ST) -ANSWER-Rhythm: Regular
Rate: 100 - 160
, P waves: 1 P wave before each QRS, Normal in appearance
PR: .12 seconds - .20 seconds
QRS: < .12 seconds
Sinus Bradycardia (SB) -ANSWER-Rhythm: Regular
Rate: 40 - 60
P waves: 1 P wave before each QRS, Normal in appearance
PR: .12 seconds - .20 seconds
QRS: < .10 seconds
Sinus Arrhythmia -ANSWER-Rhythm: Irregular
Rate: 60 - 100
P waves: 1 P wave for each QRS, Normal in appearance
PR: .12 seconds - .20 seconds
QRS: < .10 seconds
Seen a lot in pediatric patients (called a respiratory variance because
when they breathe in and out their HR changes, this is normal for kids)
Premature Atrial Contractions (PAC) -ANSWER-Rhythm: Underlying
rhythm regular, Irregular with PAC
Rate: Rate of underlying Rhythm
P waves: PAC P Wave is premature, Abnormal in size, shape or
direction, May be hidden
PR: .12 seconds - .20 seconds (may be prolonged
QRS: < .10 seconds
When you see a PAC it is superimposed on another rhythm, usually
normal sinus rhythm
Atrial Tachycardia (PAT) -ANSWER-Rhythm: Regular
Rate:140-250
