A nurse is caring for a client who has angina. Exhibits Complete the following sentence by using the lists of options. The client is at risk for developing dropdowndue todropdown.

Rationale for correct choices: Myocardial infarction: Elevated troponin levels are a specific biomarker for myocardial injury. The client’s Troponin T rose from 0.08 to 0.2 ng/mL, and Troponin I from 0.01 to 0.1 ng/mL, both exceeding normal limits, suggesting ongoing cardiac muscle damage consistent with a myocardial infarction. Troponin levels: Troponins are proteins released into the bloodstream when cardiac muscle is injured. A marked rise in both Troponin T and I over a short period indicates acute coronary syndrome progressing to myocardial infarction, especially in a client with chest pain unrelieved by nitroglycerin. Rationale for incorrect choices: Bleeding: The client’s aPTT is 32 seconds and platelet count is 350,000/mm³, both within normal ranges. These do not suggest any coagulopathy or increased bleeding risk, especially prior to thrombolytic therapy. Pulmonary embolism: While shortness of breath and anxiety can be symptoms of a pulmonary embolism, the primary lab indicator—rising troponins—points toward cardiac injury. Additionally, pulmonary embolism is typically diagnosed with D-dimer, CT angiography, or V/Q scan, not troponin trends. Shortness of breath: Though concerning, shortness of breath is a nonspecific symptom and can occur in multiple conditions including angina, anxiety, and myocardial infarction. It is not the primary diagnostic indicator in this case and does not support a specific risk like the troponin trend does. aPTT levels: The client’s aPTT is 32 seconds, which is within the normal reference range of 30–40 seconds. This does not suggest impaired clotting and therefore does not indicate a bleeding risk at this time.
