RNSG 2539 EXAM 2 CERTIFICATION
EVALUATION SET 2026 ANSWERS
GUARANTEED PASS
⫸ Duration of PR interval Answer: .12-.20 seconds
⫸ Duration of QRS Complex Answer: .04-.12 seconds
⫸ Duration of ST segment Answer: .12 seconds
⫸ Duration of T wave Answer: .16 seconds
⫸ Duration of QT interval Answer: .34-.43 seconds
⫸ Causes of prolonged p wave Answer: conduction problems within the
SA node or the atria
⫸ Causes of prolonged PR interval 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: Answer: Right coronary artery
,⫸ Normal Cardiac output range Answer: 4-8 L/min
⫸ How to measure pulse pressure Answer: Usually about 1/3 of the
systolic blood pressure
*(ex 120/80 --> PP = 40)*
⫸ How to calculate MAP Answer: (2DBP + SBP) /3
⫸ Normal MAP range Answer: 60-110
⫸ Normal range for BNP Answer: <100 = normal
⫸ Common emergency medications for an MI Answer: Oxygen
Nitroglycerine
Morphine
Aspirin 162- 325 mg
⫸ Non-specific marker of CAD
Used to indicate inflammation
Produced by the liver Answer: C-reactive protein
,⫸ Relationship between gradual/sudden onset CAD and collateral
circulation 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 Answer: White
men have highest incidence
African Americans have an earlier onset
⫸ Gender differences associated with CAD 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 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 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 Answer: 1. Must be kept in a cool, dark place
2. Do not combine with viagra
