test 2 Flashcards
Heart failure management
Digoxin side effects
Report fatigue, muscle weakness, confusion, loss of appetite
toxicity warnings and symptoms
Lack of appetite, nausea, vomiting, or diarrhea
Headache, confusion, anxiety, or hallucinations
Restlessness, weakness, or depression
Changes in vision such as blurred vision or seeing halos around bright objects
A fast, slow, or irregular heartbeat, or palpitations (fast, forceful heartbeats in an irregular rhythm)
digoxin patient education
Count pulse for 1 min before taking the medication. If the pulse rate is irregular or the pulse rate is outside of the limitations set by the provider (usually less than 60/min or greater than 100/min), hold the dose and contact the provider.
Take the digoxin dose at the same time each day.
Do not take digoxin at the same time as antacids. Separate the two medications by at least 2 hr.
Report manifestations of toxicity, including nausea, fatigue, muscle weakness, confusion, and loss of appetite.
Have blood digoxin and potassium levels checked regularly.
furosemide side effects (diuretic)
Dehydration
Hypokalemia
Hypomagnisemia
Hypovolemia
Metabolic Acidosis
furosemide patient education
Furosemide IV: no faster than 20mg/min
Teach: ingest foods/drinks high in potassium (if taking loop & thiazide)
heart failure classifications
class 1- no symptoms
class 2- mild symptoms, comfortable at rest, slight limits
class 3- moderate symptoms with less than normal physical activity, only comfortable at rest
class 4- severe symptoms- minimal physical activity even at rest
left sided heart failure symptoms
Dyspnea, orthopnea (shortness of breath while lying down), nocturnal dyspnea
Fatigue
Displaced apical pulse (hypertrophy)
S3 heart sound (gallop)
Pulmonary congestion (dyspnea, cough, bibasilar crackles)
Frothy sputum (can be blood-tinged)
Altered mental status
Manifestations of organ failure, such as oliguria (decrease in urine output)
Nocturia
Heart failure interventions
Monitor daily weight and I&O.
Assess for shortness of breath and dyspnea on exertion.
Administer oxygen as prescribed.
Monitor vital signs and hemodynamic pressures.
Position the client to maximize ventilation (high-Fowler’s).
Monitor diagnostic results to track progress.
Assess for manifestations of medication toxicity (digoxin toxicity).
Encourage bed rest until the client is stable.
Encourage energy conservation by assisting with care and ADLs.
Maintain dietary restrictions as prescribed (restricted fluid intake, restricted sodium intake).
Provide emotional support to the client and family.
right sided heart failure symtoms
Jugular vein distention
Ascending dependent edema (legs, ankles, sacrum)
Abdominal distention, ascites
Fatigue, weakness
Nausea and anorexia
Polyuria at rest (nocturnal)
Liver enlargement (hepatomegaly) and tenderness
Weight gain
American College of Cardiology and American Heart Association staging heart failure
A: High risk for developing heart failure
B: Cardiac structural abnormalities or remodeling but no manifestations of heart failure
C: Current or prior manifestations of heart failure
D: Refractory end-stage heart failure
Left-sided heart (ventricular) failure risk factors
Hypertension
Coronary artery disease, angina, MI
Valvular disease (mitral and aortic)
Smoking
Right-sided heart (ventricular) failure risk factors
Left-sided heart (ventricular) failure
Right ventricular MI
Pulmonary problems (COPD, pulmonary fibrosis)
heart failure dishcharge instructions
Take diuretics in the early morning and early afternoon.
Restrict fluid and sodium as instructed. Regulate potassium intake as instructed to prevent high or low potassium levels. A dietitian can help with menu planning.
Check weight daily at the same time, and notify the provider for a weight gain of 0.9 kg to 1.4 kg (2 to 3 lb) in 1 day or 2.3 kg (5 lb) in 1 week.
Schedule regular follow-up visits with the provider.
Obtain the pneumococcal and yearly influenza vaccines.
Initiate regular exercise as tolerated and prescribed.
Participate in cardiac rehabilitation program.
