A nurse is reviewing the laboratory values of a client who had a myocardial infarction 3 hr ago. The nurse should expect which of the following laboratory values to be elevated?
Serum amylase
Unconjugated bilirubin
Aspartate aminotransferase (AST).
Troponin I
The Correct Answer is D
A. Serum amylase: Serum amylase is an enzyme associated with pancreatic function, and its elevation is not specific to myocardial infarction.
B. Unconjugated bilirubin: Elevation of unconjugated bilirubin is associated with liver function and hemolysis, not specifically with myocardial infarction.
C. Aspartate aminotransferase (AST): While AST may be elevated in conditions affecting the heart, it is not as specific or sensitive for myocardial infarction as troponin I.
D. Troponin I: This is the correct answer. Troponin I is a cardiac-specific biomarker released into the bloodstream when there is damage to cardiac muscle, such as during a myocardial infarction. Troponin I levels start to rise within 3-4 hours after the onset of myocardial infarction, making it a crucial marker for early detection.

Correct Answer is D
Explanation
A. Aortic regurgitation: Aortic regurgitation typically presents with a diastolic murmur, not a systolic click.
B. Mitral stenosis: Mitral stenosis presents with a diastolic murmur, often associated with an opening snap, rather than a systolic click.
C. Aortic stenosis: Aortic stenosis typically presents with a systolic ejection murmur, but not a systolic click.
D. Mitral valve prolapse: This is the correct answer. Mitral valve prolapse (MVP) is characterized by the displacement of the mitral valve leaflets into the left atrium during systole, often producing a systolic click. Symptoms associated with MVP can include atypical chest pain, palpitations, and exercise intolerance.
Correct Answer is D
Explanation
A. Call emergency services for the client: While difficulty breathing is a concerning symptom, the immediate priority is to assess the client's respiratory status to determine the cause and appropriate interventions. Calling emergency services may be necessary based on the assessment findings, but assessment comes first.
B. Increase the oxygen flow to 3 L/min: Adjusting oxygen flow may be part of the intervention, but it should be based on a comprehensive assessment of the client's respiratory status. Simply increasing the oxygen flow without a thorough assessment may not address the underlying issue.
C. Have the client cough and expectorate secretions: This action may be appropriate if the client is experiencing difficulty breathing due to increased bronchial secretions. However, assessment is needed to determine the cause of the difficulty breathing before implementing interventions.
D. Assess the client's respiratory status: This is the correct answer. Assessment is the priority when a client with COPD on oxygen reports difficulty breathing. The nurse should gather information about the client's respiratory rate, effort, oxygen saturation, lung sounds, and overall respiratory distress to determine the appropriate course of action.
