,QUESTIONS AND ANSWERS
Duration of P wave. ( CORRECT ANSWER ) .06-.12 seconds
Duration of PR interval. ( CORRECT ANSWER ) .12-.20 seconds
Duration of QRS Complex. ( CORRECT ANSWER ) .04-.12 seconds
Duration of ST segment. ( CORRECT ANSWER ) .12 seconds
Duration of T wave. ( CORRECT ANSWER ) .16 seconds
Duration of QT interval. ( CORRECT ANSWER ) .34-.43 seconds
Causes of prolonged p wave. ( CORRECT ANSWER ) conduction problems within the SA
node or the atria
Causes of prolonged PR interval. ( CORRECT ANSWER ) conduction problem within the AV
node, bundle of HIS, bundle branches or aorta
In 90% of people, the AV node and bundle of HIS receive blood supply from:. ( CORRECT
ANSWER ) Right coronary artery
Normal Cardiac output range. ( CORRECT ANSWER ) 4-8 L/min
How to measure pulse pressure. ( CORRECT ANSWER ) Usually about 1/3 of the systolic
blood pressure
*(ex 120/80 --> PP = 40)*
How to calculate MAP. ( CORRECT ANSWER ) (2DBP + SBP) /3
Normal MAP range. ( CORRECT ANSWER ) 60-110
Normal range for BNP. ( CORRECT ANSWER ) <100 = normal
Common emergency medications for an MI. ( CORRECT ANSWER ) Oxygen
Nitroglycerine
Morphine
Aspirin 162- 325 mg
Non-specific marker of CAD
Used to indicate inflammation
Produced by the liver. ( CORRECT ANSWER ) C-reactive protein
, Relationship between gradual/sudden onset CAD and collateral circulation. ( CORRECT
ANSWER ) Gradual onset of CAD allows for the arteries to develop collateral circulation and
the body may still receive adequate O2
Sudden onset CAD may not allow time for collateral circulation to develop and the body may
not receive an adequate amount of O2
Non-modifiable risk factors associated with CAD. ( CORRECT ANSWER ) White men have
highest incidence
African Americans have an earlier onset
Gender differences associated with CAD. ( CORRECT ANSWER ) *MEN*
More likely to experience MI first time vs Angina
Report more typical S&S of angina and MI
*WOMEN*
Experience onset typically 10 yrs later than men
Seek help later than men
First event is usually unstable angina
Higher mortality rate from CABG
Clinical presentations of chronic stable angina. ( CORRECT ANSWER ) Pain that occurs
intermittently over a period of time and is relieved by rest
Occurs with increased physical demand
Does not change with positioning and described as tightness
*may radiate to jaw, neck, shoulders or arms*
*women often report atypical symptoms such as dyspnea and fatigue = angina equivalent*
ST segment depression or T wave inversion
Controlled with drugs on outpatient basis and taken at a specific time
Prinzmetals Angina Manifestations. ( CORRECT ANSWER ) Occurs at rest
May be relieved with mild exercise
Cyclic, short burst of pain at same time each day
CC blockers and nitrates used to control pain
Drug alert for Nitrates. ( CORRECT ANSWER ) 1. Must be kept in a cool, dark place
2. Do not combine with viagra
