QuestionSBA
QuestionChoice
C-type natriuretic peptide (CNP) is released from the vascular endothelium, not the ventricles. These peptides cause vasodilatation and natriuresis (which is an increase in sodium excretion) in an attempt to decrease fluid overload.

d
C-type natriuretic peptide (CNP) from the ventricles
QuestionChoice
BNP is released from the ventricles in response to cardiac strain. BNP, along with atrial natriuretic peptide and C-type peptide cause vasodilatation and natriuresis (which is an increase in sodium excretion) in an attempt to decrease fluid overload.

a
Brain natriuretic peptide (BNP) from the ventricles
QuestionChoice
Atrial natriuretic peptide (ANP) is released from the atria, not the vascular endothelium. These peptides cause vasodilatation and natriuresis (which is an increase in sodium excretion) in an attempt to decrease fluid overload.

e
Atrial natriuretic peptide (ANP) from the vascular endothelium
QuestionChoice
Atrial natriuretic peptide (ANP) is secreted from the atria, not the ventricles. These peptides cause vasodilatation and natriuresis (which is an increase in sodium excretion) in an attempt to decrease fluid overload.

c
Atrial natriuretic peptide (ANP) from the ventricles
QuestionChoice
Even though the name might suggest this, BNP is secreted from the ventricles, not the brain. These peptides cause vasodilatation and natriuresis (which is an increase in sodium excretion) in an attempt to decrease fluid overload.

A 68-year-old male presents to the GP with shortness of breath and swelling of his legs which have gradually gotten worse over the last 5 months. He has noticed that he cannot walk to the shops without getting out of breath and that his shoes are getting tighter around his ankles. The GP suspects he has heart failure and orders a specific blood test to help confirm the diagnosis.

Given the diagnosis, what molecule is this blood test measuring and where is it released from?
