|
Definition
|
|
Term

|
Term
What are the effects of Digoxin on the heart? |
|
Definition
•Increases the contractility of cardiac muscle •Slows heart rate and conduction |
|
|
Term
What assessment must be made before administering Digoxin? |
|
Definition

|
|
Term
What are S&S of endocarditis? |
|
Definition
1.Fever 2.Chills, malaise, night sweats, fatigue 3.Murmurs 4.Symptoms of heart failure 5.Atrial embolization |
|
|
Term
What are S&S of pericarditis? |
|
Definition
1.Pain: sudden, sharp, severe: a.Substernal, radiating to the back or arm b.Aggravated by coughing, inhalation, deep breathing c.Relieved by leaning forward 2.Pericardial friction rub 3.Fever |
|
|
Term
How does infective endocaarditis damage the heart valves? What does this put the pt at risk for and what can it lead to? |
|
Definition
Infective endocarditis damage to heart valves occurs with the growth of vegetative lesions on valve leaflets. These lesions pose a risk for embolization, erosion or perforation of the valve leaflets, or abscesses within adjacent myocardial tissue. Valvular stenosis or regurgitation (insufficiency), most commonly of the mitral valve, can occur, depending on the type of damage inflicted by the lesions, and can lead to symptoms of left- or right-sided heart failure |
|
|
Term
What sound is an indication of pericarditis? |
|
Definition
|
|
Term
What ECG changes indicate pericarditis? |
|
Definition
ST-segment elevation and T-wave inversion |
|
|
Term
Describe the antibiotic regimen of the pt with endocarditis? |
|
Definition
Administer antibiotics IV for 4 to 6 weeks. The American Heart Association recommends administration of erythromycin before dental or genitourinary procedures. Clients may be instructed in IV therapy for home health care. |
|
|
Term
What needs to be part of pt teaching regarding future doctor visits for the pt with endocarditis? |
|
Definition
5.Instruct client to inform dentist and other health care providers of history. |
|
|
Term
What are some causes of valvular heart disease? |
