Inherent rate of sa node - Study guides, Class notes & Summaries

Automaticity correct answers The ability to act as an impulse, initiating electrical activity and spontaneous depolarization (this is the most important difference between cardiac and skeletal muscle cells) Excitability correct answers The ability to respond to a stimulation and initiate an impulse Conductivity correct answers The ability to transmit an impulse that has been initiated and passes along cell membrane Refractoriness correct answers The inability of a muscle cell fiber to r...

The heart valve that is located between the right atrium and the right ventricle CORRECT ANSWER Tricuspid Valve inherent rate of conduction SA node CORRECT ANSWER 60-100 Are infants Mouth or Nose Breathers? CORRECT ANSWER Nose During Triage of MCI cardiac arrest would be? CORRECT ANSWER Black hypoxemia CORRECT ANSWER decreased level of oxygen in the blood Typical Tidal volume of male patient CORRECT ANSWER 500 Ml Type 1 Diabetes typically takes insulin daily? CORRECT ANSWER Tru...

2 types of cardiac cells - Electrical -specialized cells which conduct electrical impulses -these cells start and transmit electrical activity in the heart Mechanical -cells which make up bulk musculature in the heart -these cells contract in response to stimuli from the electrical cells 2 types of cardiac cells - Electrical -specialized cells which conduct electrical impulses -these cells start and transmit electrical activity in the heart Mechanical -cells which make up bulk musculat...

Med-Surg Telemetryelectrical systole - correct answer activation excitation depolarization electrical diastole - correct answer recovery repolarization mechanical systole - correct answer shortening contraction emptying mechanical diastole - correct answer lengthening relaxation filling automaticity - correct answer ability to initiate and maintain electrical rhythm excitability - correct answer ability to respond to electrical stimulus conductivity - correct answ...

Basic ECG Interpretation correct answers -Normal conduction system = *electrical impulses* -Components of an ECG complex -Determining rate & regularity -Measuring intervals (PR, QRS & QT) -*Identify*: Normal Sinus Rhythm, Sinus Bradycardia, Sinus Tachycardia & Sinus Arrythmia & Treatment for each Cardiac Conduction correct answers -based on automaticity( ability of heart cells to spontaneously generate an action potential) -conductivity (ability for cardiac cells to transmit acti...

Anatomy and physiology of the *CARDIAC SYSTEM:* - Heart: ▪ Hollow, cone-shaped, size of fist ▪ Located in mediastinum ▪ Enclosed by the *pericardium* = LAYERS INCLUDE = ▪ *epicardium* (a serous membrane that forms the innermost layer of the pericardium) ▪ *myocardium* (the middle and thickest layer of the heart wall) ▪ *endocardium* (lines the inside of the chambers of the heart and forms the surface of the valves ▪ Chambers are two upper atria, two lower ventricles separate...

What is repolarization? - period of rest, no electrical activity is occurring and a straight line is recorded on the EKG What is depolarization? - period of contraction Where is the SA node? What is it's inherent rate? - At the junction of the superior vena cava and right atrium, rate is 60-100 What is the rate of the AV node and what does it do? - Rate 40-60, control the number of impulses which reach the ventricles and prevents them from contracting before adequate filling occurs

Critical Care Exam 1 Practice Questions and Answers 100% Pass The nurse is caring for a patient admitted with unstable angina. The laboratory result for the initial troponin I is elevated in this patient. The nurse should recognize what implication of this assessment finding? A) This is only an accurate indicator of myocardial damage when it reaches its peak in 24 hours. B) Because the patient has a history of unstable angina, this is a poor indicator of myocardial injury. C) This is an a...
