Stroke: Ischemic stroke, Hemorrhagic stroke, Transient ischemic attack (TIA)
Stroke: Ischemic stroke, Hemorrhagic stroke, Transient ischemic attack (TIA) ( 5 Questions)
This is an incorrect answer. Elevated troponin level is not a finding that indicates atrial fibrillation as the cause of ischemic stroke. Troponin is a cardiac enzyme that is released into the bloodstream when there is damage to the heart muscle, such as in myocardial infarction (MI) or heart failure. Troponin level may be elevated in some clients who have ischemic stroke due to concurrent cardiac conditions, but it does not indicate the source of embolism.
This is a correct answer. Elevated D-dimer level is a finding that indicates atrial fibrillation as the cause of ischemic stroke. D-dimer is a protein fragment that is produced when a blood clot is dissolved by fibrinolysis. D-dimer level may be elevated in clients who have ischemic stroke due to embolism from atrial fibrillation, which is an irregular and rapid heart rhythm that causes poor blood flow and clot formation in the atria.
This is an incorrect answer. Elevated C-reactive protein level is not a finding that indicates atrial fibrillation as the cause of ischemic stroke. C-reactive protein is an inflammatory marker that is produced by the liver in response to infection, inflammation, or tissue injury. C-reactive protein level may be elevated in clients who have ischemic stroke due to various causes, but it does not indicate the source of embolism.
This is an incorrect answer. Elevated INR is not a finding that indicates atrial fibrillation as the cause of ischemic stroke. INR is a measure of how long it takes for blood to clot, which reflects the effect of anticoagulant medications such as warfarin. INR may be elevated in clients who have ischemic stroke due to anticoagulant therapy, but it does not indicate the source of embolism.
Choice A reason:
This is an incorrect answer. Elevated troponin level is not a finding that indicates atrial fibrillation as the cause of ischemic stroke. Troponin is a cardiac enzyme that is released into the bloodstream when there is damage to the heart muscle, such as in myocardial infarction (MI) or heart failure. Troponin level may be elevated in some clients who have ischemic stroke due to concurrent cardiac conditions, but it does not indicate the source of embolism.
Choice B reason:
This is a correct answer. Elevated D-dimer level is a finding that indicates atrial fibrillation as the cause of ischemic stroke. D-dimer is a protein fragment that is produced when a blood clot is dissolved by fibrinolysis. D-dimer level may be elevated in clients who have ischemic stroke due to embolism from atrial fibrillation, which is an irregular and rapid heart rhythm that causes poor blood flow and clot formation in the atria.
Choice C reason:
This is an incorrect answer. Elevated C-reactive protein level is not a finding that indicates atrial fibrillation as the cause of ischemic stroke. C-reactive protein is an inflammatory marker that is produced by the liver in response to infection, inflammation, or tissue injury. C-reactive protein level may be elevated in clients who have ischemic stroke due to various causes, but it does not indicate the source of embolism.
Choice D reason:
This is an incorrect answer. Elevated INR is not a finding that indicates atrial fibrillation as the cause of ischemic stroke. INR is a measure of how long it takes for blood to clot, which reflects the effect of anticoagulant medications such as warfarin. INR may be elevated in clients who have ischemic stroke due to anticoagulant therapy, but it does not indicate the source of embolism.
