Describe what’s happening in mitral valve stenosis. Blood slips through the stenosed mitral valve back into the left atrium.
Valvular dysfunction is more common on which side of the heart? Which valves are most commonly affected by valvular heart disease? Most valvular dysfunction takes place on the left side of the heart. The mitral valve is the most common followed by the aortic valve.
Define valvular heart disease. Heart valves that are unable to open fully (stenosis) or close fully (insufficiency or regurgitation)
Discuss the use of antibiotics as it relates to the patient with endocarditis. Administer antibiotics for 4-6 wks. AHA recommends erythromycin before dental or genitourinary procedures. Clients may be instructed in IV therapy for home health care.
How does the nurse care for the patient with pericarditis? Provide rest and position of comfort. Administer analgesics and anti-inflammatory drugs.
Give a couple of applicable nursing diagnoses for inflammatory/infectious heart disease patients. Decreased cardiac output; Risk for injury: emboli
What is a defining symptom of pericarditis? Friction rub
Explain how the heart valves are damaged with endocarditis. by the growth of vegetative lesions
Define pericarditis. inflammation of the outer lining of the heart
What symptoms might the nurse find on assessment of a patient with endocarditis (8)? Fever, chills, malaise, night sweats, fatigue, symptoms of heart failure, atrial embolization, murmurs
Name 7 causes of pericarditis (TMN CHII). Trauma, MI, Neoplasm, Connective tissue disease, Heart surgery, Idiopathic, Infections
Define Heart Failure. Inability of the heart to pump sufficient blood to meet the oxygen demands of the tissues
Describe atrial flutter. What would it look like on an ECG? fluttering in chest, ventricular rhythm stays regular, saw toothed waves between QRS spikes
How does ventricular tachycardia look on an ECG? Wide, bizarre QRS
Name 3 electrolytes that if out of balance could result in dysrhythmias. Potassium, calcium, and magnesium
Name 5 drugs that could cause dysrhythmias. Digoxin, quinidine, caffeine, nicotine, alcohol
Define dysrhythmia. disturbance in the heart rate or rhythm
What drug’s effectiveness is measured by PTT? Heparin
How reliable is Homan sign? Only about 10% of patients with phlebitis manifest Homan sign and there are many false positives
Define Thrombophlebitis. Inflammation of the venous wall with the formation of a clot
What is the end result of an untreated abdominal aortic aneurysm? Rupture/death
What is the most common cause of AAA? Atherosclerosis
Define AAA (abdominal aortic aneurysm). dilatation of the abdominal aorta caused by an alteration in the integrity of its wall
What is the antidote for Warfarin (Coumadine)? Vitamin K
What is the antidote for heparin? Protamine sulfate
How is heparin administered? Heparin is administered SQ or IV
What drug may be given post surgery for PVD? Why? Anticoagulant to prevent thrombosis
What complication does the nurse assess frequently for after surgical intervention for PVD? hemorrhage
What can we teach the patient with PVD to prevent further injury? Change position frequently; wear nonrestrictive clothing; avoid crossing legs; avoid keeping legs dependent; wear good shoes; proper foot and nail care
What lifestyle changes can the nurse teach the client with hypertension about? stress reduction, weight loss, tobacco cessation, exercise
