The nurse recalls that which type of drug therapy is used to treat volume overload in patients with acute decompensated heart failure (ADHF)?
Diuretics
Narcotics
Vasodilators
Positive inotropes
The Correct Answer is A
Diuretics are the primary class of drugs used to treat volume overload in patients with acute decompensated heart failure (ADHF). These medications help to increase urine output, reducing the overall fluid volume in the body and relieving congestion in the lungs and other tissues.
The goal of using diuretics in ADHF is to alleviate symptoms such as shortness of breath, edema (swelling), and fluid retention by promoting the elimination of excess fluid. The most commonly used diuretics in this setting are loop diuretics (e.g., furosemide, bumetanide), which have a potent diuretic effect and can rapidly reduce fluid overload.
While narcotics, vasodilators, and positive inotropes may have roles in specific cases of ADHF, they are not the primary drugs used to treat volume overload. Narcotics may be used for pain management, vasodilators to reduce afterload (the resistance the heart has to pump against), and positive inotropes to increase the heart's contractility in certain situations. However, the first-line treatment for volume overload in ADHF is diuretic therapy.

Correct Answer is D
Explanation
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.
Correct Answer is D
Explanation
Discharge teaching for a client with heart failure and reduced ejection fraction should prioritize education about medications that are essential in managing heart failure, such as angiotensin-converting enzyme (ACE) inhibitors.
ACE inhibitors are a class of medications commonly prescribed to heart failure patients with reduced ejection fraction. They work by dilating blood vessels, reducing the workload on the heart, and improving the heart's pumping ability. They are one of the cornerstones of heart failure management and have been shown to reduce symptoms, improve quality of life, and prolong survival in heart failure patients.
Educating the client about the benefits and effects of ACE inhibitors is crucial to promote medication adherence and ensure they understand the importance of taking this medication as prescribed. Common side effects, such as dizziness or dry cough, should also be discussed so the client knows what to expect and when to notify their healthcare provider.
While the other options may also be relevant to a client with heart failure, including starting an aerobic exercise program (A), reducing salt intake (B), and scheduling regular follow-up appointments (C), the immediate priority in discharge teaching should be about the medication regimen and the specific benefits and effects of ACE inhibitors. Other aspects of heart failure management can be addressed during the overall education and follow-up sessions.
