304 Heart Failure

Front

What is heart failure?

Back

Heart failure is a chronic condition in which the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs.

Front

What are the common symptoms of heart failure?

Back

Common symptoms include shortness of breath, fatigue, swollen legs, and rapid or irregular heartbeat.

Front

What is the significance of B-type natriuretic peptide (BNP) in heart failure?

Back

BNP is a hormone produced by the heart; elevated levels indicate heart failure and can help assess the severity of the condition.

Front

What is the role of diuretics in heart failure management?

Back

Diuretics help reduce fluid overload by increasing urine output, which alleviates symptoms like edema and shortness of breath.

Front

What is orthopnea?

Back

Orthopnea is difficulty breathing when lying flat, often experienced by patients with heart failure.

Front

What is the purpose of positioning a heart failure patient in a sitting position?

Back

Sitting helps reduce the workload on the heart and improves breathing by allowing better lung expansion.

Front

What are the potential complications of administering captopril in heart failure patients?

Back

Complications may include hypotension, hyperkalemia, and renal impairment.

Front

What is the importance of monitoring potassium levels in heart failure patients on ACE inhibitors?

Back

ACE inhibitors can increase potassium levels, leading to hyperkalemia, which can cause serious cardiac issues.

Front

What does a urine output of 15 mL over 2 hours indicate in a heart failure patient?

Back

It indicates possible acute kidney injury or severe fluid overload, requiring immediate medical attention.

Front

What is the significance of confusion in heart failure patients?

Back

Confusion may indicate decreased cerebral perfusion due to low cardiac output, signaling a critical condition.
