Question 5 of 5
A client is admitted to the hospital for shortness of breath and chest pain after an episode of syncope. Which laboratory finding is most important for the nurse to report to the healthcare provider?
Correct Answer: C
Rationale: Troponin I is the most important lab finding to report in a client with shortness of breath, chest pain, and syncope. These symptoms suggest a cardiac event like myocardial infarction, and troponin I is a specific marker of myocardial injury, guiding diagnosis and treatment (e.g., catheterization). Hematocrit reflects blood volume, glucose relates to metabolic issues, and oxygen saturation, while critical, is a vital sign, not a lab test. Troponin's elevation indicates urgent cardiac damage needing immediate attention.
