NSG4330 - Midterm #1 QUESTIONS WITH |\ |\ |\ |\ |\ |\




ANSWERS

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
|\ |\ |\ |\ |\ |\ |\ |\ |\




Normal myoglobin - CORRECT ANSWERS ✔✔<90 mcg/L
|\ |\ |\ |\ |\ |\




Unstable Angina - CORRECT ANSWERS ✔✔New onset chest pain
|\ |\ |\ |\ |\ |\ |\ |\ |\


that occurs at rest or is worsening without cell death. Can be
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


stable angina that becomes unpredictable.
