QuestionSBA
QuestionChoice
Dehydration reduces systemic blood volume, which decreases renal blood flow, causing the kidneys to release angiotensin II (which vasoconstricts efferent arterioles) and prostaglandins (which dilates afferent arterioles). This leads to reduced fluid pressure in the glomerulus, reducing GFR.

Dehydration
QuestionChoice
Chronic kidney disease can lead to issues such as dehydration and volume loss as the kidneys are responsible for maintaining fluid balance. This decreases renal blood flow, causing the kidneys to release angiotensin II (which vasoconstricts efferent arterioles) and prostaglandins (which dilates afferent arterioles). This leads to reduced fluid pressure in the glomerulus, reducing GFR.

d
Chronic kidney disease
QuestionChoice
Raised GFR can be caused by a build-up of pressure in the glomerulus from constricted efferent or dilated afferent arterioles. High dietary proteins can lead to afferent arteriole dilation.

a
Increased dietary protein
QuestionChoice
Hypotension decreases renal blood flow, causing the kidneys to release angiotensin II (which vasoconstricts efferent arterioles) and prostaglandins (which dilates afferent arterioles ). This leads to reduced fluid pressure in the glomerulus, reducing GFR.

e
Low blood pressure
QuestionChoice
Large losses of blood cause hypotension, which decreases renal blood flow, causing the kidneys to release angiotensin II (which vasoconstricts efferent arterioles) and prostaglandins (which dilates afferent arterioles). This leads to reduced fluid pressure in the glomerulus, reducing GFR.

A 43-year-old man has been started on spironolactone and requires monthly renal function monitoring. His two most recent results show a significant raise in eGFR.

Which of the following is the most likely cause of his results?
a
