EKG Exam NYU LangoneA delayed conduction of the AV node is manifested by a:
a. prolonged PR interval
b. widened QRS
c. inverted P wave
d. absence of a P wave - answer a. prolonged PR interval
Which of the following waveforms represent the electrical event that should initiate
ventricular contraction? – answer QRS complex
What is the normal range of the PR interval? - answer0.12-0.20
What is the normal length of the QRS interval? - answer below 0.12
What bpm rate is Sinus Tachycardia on a strip? - answer101-160 bpm
Which of the following describes a cells ability to spontaneously generate an impulse? -
answer automaticity
Which node independently conducts a rate of 40-60 in an adult patient? - answerAV
node
Which node independently conducts a rate of 60-100 in an adult patient? - answerSA
node 'the pacemaker of the heart'
What does the T-wave represent? - answerventricle repolarization
What is the normal PQRS ratio? - answer1:1
What is the rate on a strip for sinus bradycardia? - answerless than 60 bpm
How do you calculate the rate on a strip? - answermultiply the number of QRS's by 10
*pay attention to marks on strip to count right*
How to differentiate between normal sinus rhythm and sinus arrhythmia - answerthe
distance between each R (peak in QRS wave) is different and NOT the same within a
strip
the activation of BLANK system causes in a release in epinephrine which results in an
increase in heart rate, blood pressure, and cardiac output - answersympathetic nervous
system
, the QRS on an EKG corresponds to which of the following electrical events:
a. ventricular depolarization
b. ventricular repolarization
c. atrial repolarization
d. atrial depolarization - answera. ventricular depolarization
Inefective atrial contractions are associated with which rhythm
a. normal sinus with PAC
b. normal sinus with PVC
c. ventricular fibrillation
d. atrial fibrillation - answerd. atrial fibrillation
How can you tell a strip with normal sinus rhythm with PAC (premature atrial contraction
is occurring)? - answerThe P wave comes EARLY.
P waves occur when the atria contracts followed by the QRS and T waves. You know a
PAC is occurring when the PQRST segment happens too soon after the last PQRST.
Which of the following is a characteristic of atrial flutter? - answertombstone pattern
When taking the pulse of a patient in atrial fibrillation the nurse would expect
a. an irregular pulse and pulse deficit
b. an irregular and bounding pulse
c. a regular pulse and pulse deficit
d. a regular and bounding pulse - answera. an irregular pulse and pulse deficit
In atrial flutter the atrial rate usually ranges between: - answer250 and 400 bpm
Which of the following would you expect to see in a patient with SVT at a ventricular
rate of 220?
a. hypotension
b. hypertension
c. headache
d. pulse deficit - answera. hypotension
What will NEVER be an answer on the test? - answerHeadache
Symptoms that may be experienced by a patient who suddenly develops atrial
fibrillation with a ventricular rate of 160 include:
a. palpitations
b. dyspnea
c. hypotension
d. all of the above - answerd. all of the above
Which of the following is not an appropriate intervention for new onset symptomatic
SVT?
