Medsurg Cardiac ati Exam Questions and Answers 2024 heart failure occurs when the heart muscle is unable to pump effectively, resulting in inadequate _____, myocardial hypertrophy, and pulmonary/systemic congestion. - Answer-Heart failure _____ is a severe, life threatening accumulation of fluid in the alveoli and interstitial spaces of the lung that can result from severe heart failure - Answer-pulmonary edema class 1 HF - Answer-client exhibits no symptoms with activity. class 2 HF - An...

Tx to decrease preload - -Diuretics -Dilators (nitrates, nitroprusside, morphine) Define preload - -Preload is the volume/pressure in the ventricle at the end of DIASTOLE after the AV valves close, just prior to ejection -As preload increases, SV and CO will increase up to a point -Too high of a preload may lead to heart failure -Preload will seldom be elevate if the heart is without disease and there are no metabolic abnormalities Cardiac output equation - CO = HR x SV Components of str...

How does COPD result in atrial fibrillation and predisposition to PEs? - COPD causes pulmonary hypertension, right ventricular hypertrophy, and right atrial enlargement. The right atrial enlargement causes stretching of the atrial tissue and frequently results in atrial dysrhythmias. SA blocks, second-degree AV block type I, and third-degree AV heart block at the level of the AV node would occur in _______________ occlusion - RCA (as seen in inferior wall MIs) There is (more/less) risk of b...

2024 CVICU TEST STUDY GUIDE GRADED A+ SVO2 Mixed venous oxygen saturation (SvO2) is the percentage of oxygen bound to hemoglobin in blood returning to the right side of the heart. This refects the amount of oxygen "left over" after the tissues remove what they need. SVO2 Normal >60% Low SVO2 Inadequate oxygen delivery or increased oxygen consumption Ex: fever, pain, bleeding, infection High SVO2 increase in CO, decrease in oxygen demand, reduction in oxygen extraction Ex: anesth...

SVO2 - ANS gives us info about balance between oxygen delivery and oxygen consumption in the body SVO2 normal values - ANS 60-80% SVO2 <60% - ANS considered low SVO2 >80% - ANS considered high SVO2 <60% - ANS decreased oxygen delivery (oxygen in body is low) increased oxygen consumption reasons for decreased O2 delivery - ANS (when SVO2 is low) -- anemia, hemorrhage (pt could be bleeding), hypoxia, heart failure (decreased C...

A patient develops atrial fibrillation after abdominal surgery. Her blood pressure falls from 110/70 mm Hg to 92/68 mm Hg. The hypotension is related to which of the following? a. Decrease in ventricular contractility b. Hypovolemia c. Mural thrombi d. Decrease in ventricular filling - Correct answer: d Rationale: The contribution that atrial contraction makes to ventricular filling volume is approximately 15% to 30%. Atrial fibrillation results in quivering but not contracting atria. The...
