Q1
An 80-year-old woman with long-standing hypertension, coronary artery disease, and peripheral artery disease is started on ramipril. One week later, she complains of new-onset nausea and fatigue. Her blood pressure is 140/80 mmHg. Laboratory studies are significant for a serum creatinine that has increased from a baseline of 1.3 mg/dL to 2.9 mg/dL. This patient's acute kidney injury is most likely due to the new medication's effect on which of the following physiologic mechanisms?
