Myocarditis is inflammation of the heart muscle.
- generalized weakness;
- reduced energy stores,
- increased metabolic rate from massive production of leukocytes,
- imbalance between oxygen supply and demand (anemia and hypoxia),
- therapeutic restrictions—isolation,
- effect of drug therapy
- Verbal report of fatigue or weakness
- Exertional discomfort or dyspnea
- Abnormal heart rate or BP response
Expected Result / criteria for evaluation of patients will :
- Report a measurable increase in activity tolerance.
- Participate in ADLs to level of ability.
- Demonstrate a decrease in physiological signs of intolerance—pulse, respiration, and BP remain within client’s normal range.
Nursing intervention and Rationale for Myocarditis :
- Assess patient's response to the activity. Watch for changes and complaints of weakness, fatigue, and dyspnea related to activity.
R: myocarditis causing inflammation and possible damage to the function of myocardial cells.
- Monitor frequency / heart rhythm, BP, and respiratory frequency before and after activity and as long as necessary.
R: helps determine the degree of cardiac and pulmonary decompensation. Decrease in blood pressure, tachycardia, dysrhythmias, and tachypnea is indicative of damage to the heart of activity tolerance.
- Maintain bed rest during febrile period and according to indications.
R: improving the resolution of inflammation during the acute phase.
- Plan of care, with periods of rest / sleep without interruption.
R: provide balance in the needs which the activity relies on the heart.
- Assist patients in gradually progressive exercise program as soon as possible to get out of bed, noting the response of vital signs and patient tolerance to the increase in activity.
R: when inflammatory / basic condition is resolved, the patient may be able to perform the desired activity, except for permanent myocardial damage / complications.
- Collaboration supplemental oxygen administration as indicated.
R: maximizing the availability of oxygen to reduce the heart's workload.
