The client with PE may continue anticoagulation therapy for weeks, months, or years after discharge, depending on the risks for PE.
Typical causes of left-sided heart (ventricular) failure ? (Formally known as CHF) hypertensive, coronary artery, and valvular disease involving the mitral or aortic valve. Decreased tissue perfusion from poor cardiac output and pulmonary congestion from increased pressure in the pulmonary vessels indicate left ventricular failure.
CHF can be further divided into two subtypes: systolic heart failure and diastolic heart failure. Describe the two types. 1.Systolic heart failure results when the hrt is unable to contract forcefully enough during systole to eject adequate amounts of blood into the circulation. 2.diastolic hrt failure occurs when left ventricle is unable to relax adequately during diastole
Symptoms of left sided heart failure? blood accumulates in the pulmonary vessels. Manifestations of systolic dysfunction may include symptoms of inadequate tissue perfusion or pulmonary and systemic congestion.
What happens to the ejection fraction (the percentage of blood ejected from the heart during systole)during diastolic heart failure? The ejection fraction drops from a normal of 50% to 70% to below 40%.
What occurs during Right-sided heart (ventricular) failure ? In right-sided heart failure, the right ventricle is unable to empty completely. Increased volume and pressure develop in the systemic veins, and systemic venous congestion develops with peripheral edema.
What are common causes of Right sided heart failure? Right-sided heart (ventricular) failure may be caused by left ventricular failure, right ventricular myocardial infarction, or pulmonary hypertension.
What are some compensatory mechanisms that come into play when cardiac output is insufficient to meet the demands of the body? ▪ Sympathetic nervous system stimulation ▪ Renin-angiotensin system (RAS) activation ▪ Other neurohumoral responses ▪ Myocardial hypertrophy
Right-sided HF in the absence of left-sided HF is most often the result of ? pulmonary problems, such as chronic obstructive pulmonary disease (COPD) or cystic fibrosis.

What is an early manifestation of Left-sided HF? Cough As the amount of blood ejected from the left ventricle diminishes, hydrostatic pressure builds in the pulmonary venous system and results in fluid-filled alveoli and pulmonary congestion.
Dyspnea at rest in the recumbent (lying flat) position is known as ? Orthopnea
The signs and symptoms of HF can be considered in the context of these components of the syndrome: ▪ Failure of the left ventricle as a pump with decreased tissue perfusion and pulmonary venous congestion ▪ Failure of the right ventricle as a pump with systemic venous congestion
The following are priority nursing diagnoses for clients with HF: 1. Impaired Gas Exchange related to ventilation perfusion imbalance 2. Decreased Cardiac Output related to altered contractility, preload, and afterload 3. Activity Intolerance related to an imbalance between oxygen supply and demand
How do ACE inhibitors work? suppress the renin-angiotensin system (RAS), which is activated in response to decreased renal blood flow., resulting in arterial resistance, arterial dilation, and increased SV. These drugs block aldosterone, which prevents sodium and water retention.
What should you do when giving first dose of an ACE inhibitor? The health care provider usually starts doses of ACE inhibitors slowly and cautiously. The first dose of an ACE inhibitor is sometimes assoc. w/ a rapid drop in BP Monitor BP for several hours after the initial dose and each time the dose is increased
What are the benefits of Digoxin (digitalis) use in clients with HF? increase in contractility, a reduction in heart rate (HR), a slowing of conduction through the atrioventricular node, and an inhibition of sympathetic activity while enhancing parasympathetic activity.
What is the presentation of digitalis toxicity? Digitalis toxicity is often vague and nonspecific and includes anorexia, fatigue, and changes in mental status. Carefully monitor the apical pulse rate and heart rhythm of clients receiving digoxin.
When monitoring a client on digitalis, what s&s should you report? Report the development of either an irregular rhythm in a client with a previously regular rhythm or a regular rhythm in a client with a previously irregular one. Also, Monitor serum potassium levels (hypokalemia potentiates digitalis toxicity)
What are some symptoms of worsening HF that should be reported to physician? ▪Rapid weight gain (3 pounds in a week or 1 to 2 pounds overnight) ▪Decrease in exercise tolerance lasting 2 to 3 days ▪Excessive awakening at night to urinate ▪Development of dyspnea or angina at rest or worsening angina ▪Increased perph edema
What is Mitral Stenosis? In mitral stenosis, the valve leaflets fuse and become stiff, and the chordae tendineae contract and shorten. The valve opening narrows, preventing normal blood flow from the left atrium to the left ventricle.
What is the result of Mitral Stenosis? left atrial pressure rises, the left atrium dilates, pulmonary artery pressures increase, and the right ventricle hypertrophies. Pulmonary congestion and right-sided HF occur initially
What is the most common cause of Mitral Stenosis? Rheumatic fever is the most common cause of mitral stenosis. Mitral stenosis usually results from rheumatic carditis, which can cause valve thickening by fibrosis and calcification.
What is Rheumatic Carditis? (also called rheumatic endocarditis) is a sensitivity response that develops after an upper respiratory tract infection with group A beta-hemolytic streptococci, which occurs in about 40% of clients with rheumatic fever and affects more than one million Americans.

What is the effect of Thiazide diuretics? prevent sodium and water reabsorption in the distal tubules while promoting potassium excretion.
What is the effect of Loop diuretics? epress sodium reabsorption in the ascending loop of Henle and promote potassium excretion.
Calcium Channel Blocking Agents: Calcium channel blockers, such as diltiazem (Cardizem), lower blood pressure by interfering with the transmembrane flux of calcium ions. This results in vasodilation and subsequent decrease in blood pressure.

Most common causes of aneurysms? Atherosclerosis is the most common cause of all aneurysms, with hypertension and cigarette smoking being contributing factors. Syphilis (a sexually transmitted disease), Marfan syndrome (an autoimmune disease)
Coronary artery disease (CAD) CAD is a broad term that includes stable angina pectoris and acute coronary syndromes. CAD affects the arteries that provide blood, oxygen, and nutrients to the myocardium.
Ischemia occurs when insufficient oxygen is supplied to meet the requirements of the myocardium
Infarction necrosis, or cell death) occurs when severe ischemia is prolonged and irreversible damage to tissue results.
Angina pectoris means "strangling of the chest." Angina is a temporary imbalance between the coronary arteries' ability to supply oxygen and the cardiac muscle's demand for oxygen.
Stable angina is chest discomfort that occurs with moderate to prolonged exertion in a pattern that is familiar to the client. It is usually relieved by nitroglycerin or rest and often is managed with medication
Unstable angina (USA) is chest pain or discomfort that occurs at rest or with exertion and causes marked limitation of activity. An increase in the number of attacks and an increase in the intensity of the pain characterize USA.
Myocardial infarction (MI) occurs when myocardial tissue is abruptly and severely deprived of oxygen. When blood flow is acutely reduced by 80% to 90%, ischemia develops. Ischemia can lead to injury and necrosis (infarction)
Modifiable risk factors of MI/CAD elevated serum cholesterol levels, cigarette smoking, hypertension, impaired glucose tolerance, obesity, physical inactivity, and stress.
A client suffering from angina should feel relief upon taking nitroglycerin in how long? How many attempts at using nitro are allowed?

intestinal obstructions can be partial or complete and are classified as: Mechanical or nonmechanical obstruction
Mechanical intestinal obstruction In mechanical obstruction, the bowel is physically obstructed by disorders outside the intestine (e.g., adhesions or hernias) or by blockages in the lumen of the intestine (e.g., tumors, inflammation, strictures, or fecal impactions).
Nonmechanical intestinal obstruction Nonmechanical obstruction (also known as paralytic ileus does not involve a physical obstruction in or outside the intestine. Instead, peristalsis is decreased or absent, resulting in a slowing of the movement or a backup of intestinal contents.
inflammatory bowel disease (IBD) is used to describe two conditions of unknown etiology: ulcerative colitis and Crohn's disease
Appendicitis is acute inflammation of the vermiform appendix. Inflammation of the appendix can occur when the lumen (opening) of the appendix is obstructed. Inflammation leads to infection as bacteria invade the wall of the appendix.
Complications of appendicitis include: 1. Gangrene from hypoxia or perforation can occur within 24 to 36 hours. 2. peritonitis (inflammation of the peritoneum)
Abdominal pain that increases with cough or movement and is relieved by flexion of the right hip or the knees suggests : a perforated appendix with peritonitis.
Peritonitis is an acute inflammation of the visceral/parietal peritoneum and endothelial lining of the abdominal cavity, or peritoneum. Peritonitis can be classified as primary or secondary, localized or generalized. Peritonitis is a life-threatening illness.
What is "third spacing"? The body responds to the infectious process by shunting extra blood to the area of inflammation. Fluid is shifted from the extracellular fluid (ECF) compartment into the peritoneal cavity, connective tissues, and gastrointestinal (GI) tract
What complications does "third spacing" present? This shift of fluid out of the vascular space can result in a significant decrease in circulatory volume. Severely decreased circulatory volume can result in insufficient perfusion of the kidneys, leading to renal failure with electrolyte imbalance.
Ulcerative colitis is one of a group of bowel diseases of unknown etiology, characterized by remissions and exacerbations ("flare-ups"). It can result in loose stools containing blood and mucus, poor absorption of vital nutrients, and thickening of the colon wall.
The following are priority nursing diagnoses for clients with ulcerative colitis: 1. Diarrhea related to inflammation of the bowel mucosa 2. Acute and Chronic Pain related to inflammation and ulceration of the bowel mucosa and accompanying skin irritation The primary collaborative problem is Potential for Gastrointestinal Bleedin
