A nurse is reviewing laboratory results for a client who has pericarditis. Which of the following blood test results should the nurse anticipate? (Select All that Apply.)

A. Encouraging increased mobility: While mobility is important for overall health, it may not be the primary lifestyle modification emphasized in the discharge teaching for heart failure. The focus is typically on dietary and fluid restrictions, medication adherence, and symptom management.

B. Dietary and fluid restrictions: Dietary and fluid restrictions are essential lifestyle modifications for managing heart failure. Clients are often advised to follow a low-sodium diet and restrict fluid intake to prevent fluid retention and exacerbation of heart failure symptoms.

C. Cessation of intravenous (IV) drug use: While cessation of intravenous drug use is important for overall health and may be addressed if relevant to the client's situation, it may not be a primary focus of discharge teaching specifically related to heart failure.

D. Cessation of hormonal supplements: Cessation of hormonal supplements may be recommended if they contribute to heart failure or exacerbate its symptoms. However, this recommendation would be specific to individual client circumstances and may not apply to all clients with heart failure.

A. Creatine kinase (CK) test: While creatine kinase isoenzymes, including CK-MB, can be elevated following myocardial infarction (MI), they are not specific to cardiac muscle injury. CK is found in various tissues throughout the body, so elevated levels can also indicate damage to skeletal muscle or brain tissue, among other sources.

B. Creatine kinase-myocardial band (CK-MB) test: CK-MB is a cardiac-specific isoform of creatine kinase, and elevated levels can indicate myocardial injury, particularly in the context of an acute MI. However, troponin T is a more sensitive and specific marker for myocardial injury.

C. Brain natriuretic peptide (BNP) test: Brain natriuretic peptide is primarily used in the diagnosis and management of heart failure. While elevated BNP levels can indicate heart muscle strain or stress, they are not specific markers for acute myocardial infarction or early injury to the cardiac muscle.

D. Troponin T test: This is the correct answer. Troponin T is a highly specific marker for cardiac muscle injury. Elevated troponin levels can be detected within hours of myocardial infarction and persist for several days, making it an essential tool in the diagnosis of acute coronary syndromes, including myocardial infarction. Troponin T is considered one of the gold standard biomarkers for detecting early injury to the cardiac muscle.
