NSG4330 - Midterm #1 || Graded A+.
Three Factor Framework correct answers The Client: degree of complexity and predictability
(i.e. teaching vs. ICU), risk of negative outcomes (++ risk factors?)
The Nurse: leadership (understanding own competencies/abilities), critical thinking, decision
making abilities
The Environment: practice supports, consultation resources, stability/predictability of
environment
Coronary Arteries correct answers Rt Coronary Artery: covers entire Rt side, circles to posterior
Lt Main Coronary Artery branches into:
Circumflex: circles posterior and lateral Lt side
Lt Anterior Descending: feeds Lt ventricle
Systole vs. Diastole correct answers S: Pulmonic and aortic valves open, "lub". If BP is high,
heart must work harder to close aortic valve (usually requires only 120mmHg).
D: Bicuspid and tricuspid open, "dub". Coronary arteries fill during diastole (while aortic valve
is closed)
Cardiac Output correct answers CO = Stroke Volume x Heart Rate
Amount of blood your body ejects for 1 min
Stroke Volume correct answers The amount of blood your body ejects per beat
Preload correct answers Amount of blood in your ventricles before systole
, The greater the stretch (more blood) the better the contraction (elastic band analogy).
Low preload could be from low BP (though HR may increase to compensate), dehydration
Afterload correct answers How much pressure it takes for the heart to contract and open valve to
eject blood (Lt ventricle must push against pressure in aorta to open valve... ex. easy to open a
door, harder if there are people on the other side holding it closed).
More pressure in aorta = more pressure needed to open valve = more energy = more oxygen =
faster HR
Chronotropic ANS Controls correct answers Rate of impulse formation, controls HR
(cHRonitropic)
Dromotropic ANS Controls correct answers Speed of conduction
Inotropic ANS Controls correct answers Strength of contraction
Acute Coronary Syndrome correct answers Umbrella term for conditions that result in decrease
blood flow to heart/prolonged oxygen suplpy+demand imbalance
Unstable Angina (moreso than stable)
STEMI
non-STEMI
Normal CK correct answers 22 to 198 U/L
Normal troponin level correct answers 0.0 - 0.10 ng/mL
