An older adult male client is admitted after three reported syncopal episodes at home. He has several bruises at various stages of healing noted over his arms and legs. The cardiac monitor shows atrial fibrillation (A-fib) with a ventricular response of 140 beats/minute. In addition to contacting the client's healthcare provider (HCP), which intervention should the nurse implement?

• Congestive cardiomyopathy is the most likely condition given the client’s symptoms of labored breathing, bilateral leg edema, S3 gallop, and apical pulse displacement—all signs of fluid overload and decreased cardiac output associated with heart failure.
• Applying oxygen helps manage dyspnea and improves tissue oxygenation in clients with heart failure, especially when respiratory rate is elevated and breathing is labored.
• Requesting a chest x-ray allows for visualization of pulmonary congestion or cardiomegaly, both of which are common in heart failure and can guide further treatment decisions.
• Monitoring breath sounds helps detect improvement or worsening of pulmonary congestion, such as crackles or rales, which indicate fluid buildup in the lungs.
• Monitoring urine output evaluates kidney perfusion and fluid status, which reflects the effectiveness of heart failure treatment and overall cardiac output.
• Hypertrophic cardiomyopathy typically presents with exertional syncope or chest pain, not fluid overload signs like leg edema and S3 gallop. Apical displacement also favors dilation rather than hypertrophy.
• Dilated cardiomyopathy overlaps with congestive cardiomyopathy, but the broader term “congestive” aligns more clearly with fluid overload and heart failure signs.
• Restrictive cardiomyopathy involves impaired ventricular filling but does not usually present with displaced apical pulse or bilateral edema in early stages. It is also less common in this clinical setting.
• Starting IV fluids would worsen the client’s condition by increasing preload and exacerbating fluid overload in heart failure.
• Giving the client 80 mg of aspirin is more appropriate in acute coronary syndrome, not in managing cardiomyopathy or fluid retention.
• Preparing for cardioversion is indicated in arrhythmias like atrial fibrillation with hemodynamic instability, not in a hemodynamically stable patient with heart failure.
• Monitoring platelet count is not relevant to evaluating heart failure progression or response to treatment.
• Monitoring temperature is important for infection but does not reflect cardiac or fluid status in this context.
• Monitoring cerebral perfusion pressure is reserved for neurocritical care settings and is not appropriate for routine heart failure monitoring.

A. Assist with ambulation in the hallway: While progressive ambulation is part of cardiac rehabilitation, early ambulation too soon after a myocardial infarction may increase myocardial oxygen demand and cardiac workload.

B. Provide a bedside commode for toileting: Using a bedside commode reduces the effort and energy expenditure required to walk to the bathroom, thus lowering cardiac workload. This helps prevent unnecessary increases in heart rate and oxygen demand.

C. Encourage active range of motion exercise: Active range of motion is beneficial for preventing complications like thromboembolism, but if done too aggressively or frequently early post-MI, it can stress the heart.

D. Teach to sleep in a side-lying position: Sleeping position may affect comfort and breathing but does not significantly influence cardiac workload. Semi-Fowler’s position may be more beneficial in reducing preload in cardiac patients than simply lying on the side.
