QuestionSBA
QuestionChoice
It is B1-adrenoceptor stimulation which leads to the release of renin. This stimulates angiotensin-2 production and leads to water and salt retention. These systemic effects lead to vasoconstriction and increase blood pressure.

b
B2-adrenoceptor stimulation leads to the release of renin
QuestionChoice
A1-adrenoceptors stimulation leads to **hyper**kalaemia. A1-adrenoceptors stimulation leads to the release of potassium from the liver.

e
A1-adrenoceptors stimulation leads to hypokalaemia
QuestionChoice
A1-adrenoceptor agonists such as phenylephrine are used as nasal decongestants. Swelling in the nasal passage due to infection or inflammation leads to vasodilation. A1-adrenoceptor stimulation leads to vasoconstriction and unblocks the nose.

a
A1-adrenoceptor agonists are used as nasal decongestants
QuestionChoice
B2-adrenoceptor simulation leads to uterine smooth muscle relaxation. This is why salbutamol is used in some cases to prevent premature labour. B2-adrenoceptor stimulation additionally leads to bronchodilation and systemic vasodilation.

c
B3-adrenoceptor stimulation leads to uterine smooth muscle relaxation
QuestionChoice
B1-adrenoceptor stimulation leads to positive chronotropic and inotropic effects on the heart. B2-adrenoceptor stimulation leads to bronchodilation and uterine smooth muscle relaxation.
