Which diagnostic test will be most useful to the nurse in determining whether a client admitted with acute shortness of breath has heart failure?

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.

Resumption of sexual activity after a myocardial infarction (MI) is an important topic to address as part of the overall recovery and rehabilitation process. It should be discussed along with other physical activities during the patient's recovery. The nurse should initiate the discussion in a supportive and non-judgmental manner, addressing the patient's concerns, fears, and questions about sexual activity after an MI.

Sexual activity is a normal part of life, and patients may have concerns about the safety and appropriateness of engaging in sexual activity after a significant cardiac event like an MI. Discussing it along with other physical activities helps normalize the topic and allows the nurse to provide accurate information, address any misconceptions, and offer guidance on when and how to resume sexual activity safely. Patients should be encouraged to have an open dialogue with their healthcare provider about their concerns and any specific questions they may have related to resuming sexual activity.
