Answer 1

Question 1

Carvedilol belongs to the class of alpha and beta blockers.In simple it is alpha adrenergic receptor blocker and also beta adrenergic receptor blockers used to treat high blood pressure

Ans:True

Question 2

Glyceral triniteate is used as an antianginal drug.It is available in oral forms,as a spray ,intravenous medication,ointments and as a transdermal patch

Ans:d)all 9f the above

Question 3

The ACE inhibitors when taken stops the breakdown of bradykinin and substance P.This leads to secretions and stimulates cough .In addition to this the beta 2 receptor leads to constriction the respiratory tract, in 8rder to relieve this the cough reflex is stimulated

Inhibition of ACE leads to vasodilation

The action of angiotensin 1 and 2 decreases when reninrelease is inhibited

Activation of beta adrenergic receptor control BP

Ans:a) inhibition of bradykinin

Question 4

Cardiac output refers the quantity of blood pumped into the circulatory system with its heart rate and stroke volume

Ams:c)a product if heart rate and stroke volume
