NUR 325 Final Exam Questions and Answers | 100% Pass! The degree of stretch at the end of diastole (how much blood is in the ventricles) is known as -Answer-Preload An increase in fluids will __________ preload, and a decrease in fluids will ___________ preload -Answer-An increase in fluids will increase preload, and a decrease in fluids will decrease preload The resistance to eject blood from the ventricles is known as -Answer-Afterload Hypertension and vasoconstriction have what effect...

Pacemakers of the Heart correct answer: Sinoatrial (SA) node Atrioventricular (AV) node Bundle of His Bundle Branches Purkinje Fibers -SA node: p wave -SA node to AV node: PR segment -Impulse travels from Bundle of His to Bundle branches and then to Purkinje fibers: QRS complex -Repolarization of ventricles: T wave P wave correct answer: sinoatrial node (SA node) starts an impulse, as the wave of depolarization spreads through the atria, _______ is inscribed on the ECG AV nod...

First Degree AV Block Characteristics - ANSWER- P wave before every qrs complex - P waves are upright and uniform - LONG PR INTERVAL 2nd Degree AV Block Type 1 (Wenkebach) Characteristics - ANSWER- pr interval increases with each beat until a qrs complex is dropped 2nd Degree AV Block Type 2 (Mobitz II) Characteristics - ANSWER- p wave before each qrs - some p's are not followed by a qrs - pr interval is the same for every conducted (full) beat - usually bradycardic Third Degree A...

what is the most accurate method for acquiring heart rate? Correct Answer: 1500 method As an impulse moves toward a positive electrode it produces what type of deflection? Correct Answer: upward on ECG papers horizontal measurements are used to determine what? Correct Answer: heart rate the initiation of the impulse in the SA Node and its movement through the atria produce? Correct Answer: P-wave repolarization of the ventricles is represented by the? Correct Answer: T-wave a...

Dysrhythmia Test Questions And Answers All Correct First Degree AV Block Characteristics - P wave before every qrs complex - P waves are upright and uniform - LONG PR INTERVAL 2nd Degree AV Block Type 1 (Wenckebach) Characteristics - pr interval increases with each beat until a qrs complex is dropped 2nd Degree AV Block Type 2 (Mobitz II) Characteristics - p wave before each qrs - some p's are not followed by a qrs - pr interval is the same for every conducted (full) beat - usually ...

1ST DEGREE AV BLOCK - Answer-THE P WAVE PRECEDES EACH QRS COMPLEX BUT THE PR INTERVAL IS .0.2 SECS. 22 PREMATURE ATRIAL CONTRACTIONS - Answer-THERE ARE PREMATURE AND ABNORMALLY SHAPED P WAVES. THE PR INTERVAL IS TYPICALLY WITHIN NORMAL LIMITS, BUT MAY BE SHORT OR SLIGHTLY PROLONGED. THE QRS COMPLEX IS USUALLY WITHIN NORMAL LIMITS AND NORMAL CONFIGURATION 2ND DEGREE AV BLOCK MOBITZ 1 (WENCKEBACH) - Answer-DISEASED TISSUES OF THE AV NODE CONDUCT EACH IMPULSE EARLIER IN THE REFRACTORY PERI...
