NSG4330 - Midterm #1 Exam Questions and Answers 100% Pass

NSG4330 - Midterm #1 Exam Questions and Answers 100% Pass Three Factor Framework - Correct Answer️️ -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 Answer️️ -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 Answer️️ -S: Pulmonic and aortic valves open, "lub". If BP is high, heart must work harder to close aortic valve (usually requires only 120mmHg).Smart PDF D: Bicuspid and tricuspid open, "dub". Coronary arteries fill during diastole (while aortic valve is closed) Cardiac Output - Correct Answer️️ -CO = Stroke Volume x Heart Rate Amount of blood your body ejects for 1 min Stroke Volume - Correct Answer️️ -The amount of blood your body ejects per beat Preload - Correct Answer️️ -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 Answer️️ -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 Answer️️ -Rate of impulse formation, controls HR (cHRonitropic) Dromotropic ANS Controls - Correct Answer️️ -Speed of conductionSmart PDF Inotropic ANS Controls - Correct Answer️️ -Strength of contraction Acute Coronary Syndrome - Correct Answer️️ -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 Answer️️ -22 to 198 U/L Normal troponin level - Correct Answer️️ -0.0 - 0.10 ng/m
