Final answer:
The laboratory finding that supports the conclusion of atheroembolic renal disease is increased eosinophils.
Step-by-step explanation:
The laboratory finding that supports the conclusion of atheroembolic renal disease in the patient with acute kidney injury and secondary hypertension is: increased eosinophils.
The presence of increased eosinophils in the blood indicates an
allergic or hypersensitivity reaction
. In the case of atheroembolic renal disease, the atherosclerotic plaques can break off and embolize to the smaller blood vessels of the kidneys, resulting in inflammation and an increase in eosinophil count.
