NU 327 Exam 4 Questions with All
Correct Answers
Orthostatic Hypertension - Answer- decreases BP when moving from resting to non-
resting SBP drop 20 >mmHg or DBP 10>mmHg
Alterations in Cardiac function - Answer- Coronary Heart Disease
Ischemia
Myocardial ischemia
Agina Pectoris
myocardial infarction
Vulvar disease
Disorders of Mitral Valve
Mitral Valve Prolapse
Coronary Heart Disease - Answer- underlying cause: atherosclerosis. plaque build up in
coronary arteries (arteries that supply O2 to the heart tissue)
Ischemia - Answer- inadequate O2 supply to the myocardium b/c of impaired blood flow
Myocardium - Answer- tissues of the heart
Myocardial Ischemia - Answer- acute coronary syndrome: sudden obstruction of
coronary blood flow
Chronic CS: plaque build up over time, the heart as time to develope other pathways
Angina Pectoris - Answer- Chest pain;
Stable: narrowing/stiffening of coronary heart vessel - predictable
Variant (prinzmetal): coronary vasospasms, unpredicatbale
Unstable: hard to distinguish b/w MI
Myocardial infarction - Answer- prolonged or total disruption of blood flow to the
myocardium.
Signs of MI - Answer- 1. SEVERE chest pain that lasts >15 min
2. ECG changes - ST segment elevated or not elevated (better outcome)
3. Serum markers - CK-MB only elevated 48-72 hrs, troponin elevated longer(marker of
choice)
Treatment of MI - Answer- Reduce O2 demand, increase O2 supply, apsirin
, Vulvar disease - Answer- dmg caused by inflammaton, scarring, and calcification
Stenosis - Answer- failure for valve to open completely = increased work
Regurgitation - Answer- failure of valve to close. Backflow into prev. chamber
Prolapse - Answer- valves balloon backwards
Disorders of the mitral valve - Answer- Mitral stenosis - increases LA pressure,
increases pulmonic pressure, calcium deposits
Mitral regurgitation: back flow of blood from LV to LA = LS HF
Mitral Valve Prolapse - Answer- Mitral valve balloons into LA during systole
disorders of Aortic Valve - Answer- Aortic Stenosis - Calcium deposits on aortic cusps,
increased LV pressure, can lead to LS HF
SIGNS: Syncope, low SBP, faint pulse
Aortic regurgitations - blood leaks from aorta into LV. LS HF
Diseases of the endocardium - Answer- Rheumatic Heart Dz
Ineffective endocarditis
Rheumatic Heart Dz - Answer- predisposed by rheumatic fever.
Heart Dmged from immune attack on own tissue.
heart valves become scarred and shortened
Inefective endocarditis - Answer- infection of endocardial structures by microorganisms
= INFLAMMATION
