21.6: Cardiomyopathy VI: Nursing Management

Assessment: Nursing management of patients with cardiomyopathy begins with a thorough assessment of the patient's history, including a family history of cardiomyopathy or sudden cardiac death, personal history of heart disease, hypertension, diabetes, and any alcohol consumption or drug use.

During the physical examination, assess vital signs, look for signs of heart failure (such as edema, jugular venous distention, and cyanosis), auscultate for abnormal heart sounds (like murmurs and gallops), and check for pulmonary congestion by listening for crackles or wheezes.

Evaluate essential diagnostic tests such as an electrocardiogram (ECG) to check for arrhythmias, conduction abnormalities, ischemia, and left ventricular hypertrophy (LVH); an echocardiogram to evaluate cardiac structure and function; a chest X-ray for cardiac enlargement and pulmonary congestion; and blood tests to measure BNP (B-type Natriuretic Peptide) levels, electrolytes, kidney function, and thyroid function. These assessments are crucial for understanding the patient's condition and guiding management.

Diagnosis: Based on the assessment, the nurse formulates the following nursing diagnoses:

1. Decreased cardiac output related to structural changes in the heart, as evidenced by dyspnea, fatigue, and edema.
2. Activity intolerance related to decreased cardiac output, as evidenced by excessive fatigue and shortness of breath upon exertion.
3. Excess fluid volume related to decreased cardiac output, as evidenced by edema of lower extremities and weight gain.
4. Knowledge deficit related to the disease condition and its management, as evidenced by patient questions and misconceptions about the condition.

The nurse collaborates with the patient and sets goals for improved cardiac output with stable vital signs, relieving fluid overload symptoms, engaging in activities within tolerance levels, and verbalizing an understanding of the disease process and management strategies.

Planning

The nurse develops a comprehensive care plan and implements the following interventions:

• Position the patient in a semi-Fowler's position (head of the bed elevated 30-45 degrees) to decrease preload and reduce cardiac workload, improving breathing.
• Administer supplemental oxygen as prescribed and monitor respiratory status regularly.
• Encourage the patient to participate in a prescribed activity program or daily exercise program, with walking and other activities that do not cause unusual fatigue or dyspnea. Conserve energy by balancing activity with rest periods. Avoid strenuous activity, isometric exercises, and competitive sports.
• Encourage smoking cessation and provide resources for support. Discuss the impact of alcohol on heart health and recommend limiting or avoiding alcohol intake.
• Provide emotional support to help manage anxiety related to the illness and refer to support groups or counseling services as needed.

Patient Education:

• Emphasize the importance of taking prescribed medications and discuss common side effects and what to do if they occur.
• Educate the patient on a low-sodium diet to manage fluid retention. Encourage avoiding high-sodium foods like processed foods and salty snacks. Provide detailed guidance on dietary changes and meal planning tips.
• Explain the disease process, symptoms, and treatment plan. Emphasize the significance of medication adherence and regular follow-ups.
• Instruct the patient to weigh themselves daily at the same time. Explain why daily weighing is crucial for monitoring fluid retention.
• Teach the patient and family regarding signs of worsening heart failure, such as sudden weight gain, increased swelling, and shortness of breath, and to report these signs promptly.
• Offer a detailed explanation of symptoms of worsening heart failure and the importance of early intervention.

Evaluation: Lastly, the nurse regularly assesses the patient's vital signs and symptoms to determine whether they are improving or deteriorating and adjusts the care plan based on the patient's progress.
