My Mock Registry Flashcards
(926 cards)
What is a normal pulse rate for a healthy adult
60-100 beats/minute
Systolic blood pressure corresponds with the contraction of which chamber of the heart
Left ventricle contraction
What is a normal blood pressure
120/80 or less
Diastolic blood pressure corresponds to
Ventricular diastole or ventricular relaxation
Initial electrical impulse in the heart is generated by the
Sinus node
An elevated ST segment on an EKG indicates what
Myocardial infarction
Which reasons might a patient’s pulse ox reading fall below 90%
Sleep apneaPoorly placed oximetry sensorChronic obstructive pulmonary diseaseCardiac arrest
Which aspect of the EKG rhythm strip represents the electrical conduction through the atria of the heart
P segment (the first little bump)
Which aspect of the EKG rhythm strips represents the electrical activity of the ventricles during diastole e
T segment(small little bump at the end)
