NRSG430 Complex Care Final Exam
Questions With Verified Solutions.
Which two valves are open during ventricular systole? - Answer aortic and pulmonic
Which two valves are closed during ventricular systole? - Answer mitral and tricuspid
Amount of time systole takes in the cardiac cycle - Answer 1/3 of cardiac cycle
Amount of time diastole takes in the cardiac cycle - Answer 2/3 of cardiac cycle
How does activation of the RASS system affect both preload and after load? - Answer after
load: vasoconstriction
preload: sodium and water retention
Always use an armboard for patients with an ___________ - Answer arterial line
An arterial line should be leveled to - Answer the phlebostatic axis (4th intercostal
space/halfway point between anterior and posterior)
Causes of sinus tachycardia - Answer 1. Stress
2. Dehydration
3. Pain
4. Fever
5. Hypoxia
Starlings Law - Answer There needs to be adequate volume for there to be adequate stretch
and contractility. This is why with hypovolemia, contractility will eventually go down
Determinants of preload - Answer 1. Intravascular volume
2. Venous tone/pressure
3. Intra-pericardial pressure
, Normal CVP - Answer 5
Normal wedge pressure - Answer 10
Measures of contractility - Answer CO/CI, SV/SVI, EF
Normal ejection fraction - Answer 60-65%
Determinants of contractility - Answer 1. Preload/Afterload
2. Ventricular musculature
3. Neural control
4. Physiological depressants
5. Drug therapy
6. Intrinsic depression
7. Electrolytes
Normal SVR - Answer 800-1200
Leads that look left main - Answer V1-V6, Lead 1, AVL
Leads that look at the left anterior descending - Answer V2-V4
Circumflex/CX - Answer Lead 1 & Avl, V5 & V6
The rate of cell death in an acute myocardial infarction is dependent on - Answer collateral
circulation
myocardial oxygen supply
restoration of blood flow
Contraindications for fibrinolytics - Answer Any prior ICH, known cerebral vascular lesion,
known malignant intracranial neoplasm, ischemic stroke within 3 months, suspected aortic
