The nurse is caring for patient who has been diagnosed with an altered mycogenic

1 -- The myogenic mechanism, which responds to pressure changes in the renal blood vessels, controls the diameter of the afferent arterioles to achieve autoregulation. An increase in systemic blood pressure causes the renal vessels to constrict, whereas a decrease in blood pressure causes the afferent arterioles to dilate. These changes adjust the glomerular hydrostatic pressure and, indirectly, maintain the GFR. An alteration in this system exposes the kidneys to pressures that are too high for proper long term kidney function. Option 2 does not address the patient’s question. Option 3 and 4 are incorrect.
