The nurse is caring for a patient with manifestations of acute decompensated heart failure (ADHF). What is the priority nursing assessment?

B-type natriuretic peptide (BNP) is a diagnostic blood test that can be most useful to the nurse in determining whether a client admitted with acute shortness of breath has heart failure.

BNP is a hormone produced by the heart in response to increased pressure and volume in the heart, especially in cases of heart failure. When the heart is under stress, such as in heart failure, it releases BNP into the bloodstream. Elevated levels of BNP are strongly indicative of heart failure, and the testis particularly helpful in differentiating heart failure from other conditions that may present withsimilar symptoms, such as pulmonary disorders.

When a patient presents with acute shortness of breath, the BNP test can provide valuable information to help guide the diagnosis and treatment. If the BNP level is elevated, it suggests that heart failure is likely the cause of the symptoms, and appropriate interventions can be initiated promptly.

While other diagnostic tests like serum troponin (A) are important for assessing heart damage in conditions like myocardial infarction (heart attack), they may not be as specific for heart failure.

Arterial blood gases (B) are helpful in evaluating gas exchange and acid-base balance, especially in patients with respiratory distress, but they are not specific for diagnosing heart failure.

A 12-lead electrocardiogram (ECG) (C) can provide valuable information about the heart's electrical activity and any signs of acute myocardial infarction or other cardiac abnormalities, but it is not the primary test for diagnosing heart failure. An ECG can support the diagnosis if specific changes suggestive of heart failure are present, but the BNP test provides more direct evidence for heart failure diagnosis.

In a patient with acute decompensated heart failure (ADHF), the priority nursing assessment is to auscultate lung sounds. ADHF is characterized by the sudden worsening of heart failure symptoms, which may include pulmonary congestion and fluid accumulation in the lungs. Assessing lung sounds helps to identify signs of pulmonary edema, which is a serious complication of ADHF.

The nurse should listen for crackles or rales, which are abnormal lung sounds caused by the presence of fluid in the alveoli. These findings suggest that the patient is experiencing fluid overload and inadequate gas exchange in the lungs. Prompt recognition of pulmonary edema allows for early intervention, such as administering diuretics or other medications, to relieve fluid overload and improve respiratory function.

While the other options (B) Facial swelling, (C) Level of anxiety, and (D) Intake and output, are important assessments in a patient with heart failure, they are not the priority in a patient with manifestations of acute decompensated heart failure. The priority is to assess for signs of respiratory

distress and pulmonary congestion, as these can quickly lead to respiratory failure and life threatening complications.
