Answer 12

Preload
After load
Contractility

Question 13

most accurate MAP is from the

Answer 13

arterial line

Question 14

indicates arterial depolarization, stimulated by the SA node

Answer 14

P wave

Question 15

indicates conduction of the impulses form the SA node through the internodal pathway to the AV node and downward to the ventricles

Answer 15

PR interval

Question 16

reflect ventricular depolarization and arterial repolarization

Answer 16

QRS complex

Question 17

represents completion of ventricular depolarization and beginning of ventricular repolrization

Answer 17

ST segment

Question 18

represents repolarization of ventricles

Answer 18

t wave

Question 19

represents ventricular depolarization and repolarization

Answer 19

QT intervals

Question 20

normal value for PR interval

Answer 20

0.12- 0.2 sec

Question 21

If PR is greater than 0.2

Answer 21

represents conduction delay

Question 22

normal value for QRS complex

Answer 22

less than 0.12 sec

Question 23

if QRS complex is greater than 0.12 sec

Answer 23

suggests bundle branch block or conduction delay

Question 24

normal QT interval

Answer 24

less than half of the R-R interval
