Answer 1

Answer 1)we should call the physician as patient is having ortho static hypotension, which can leads to hyoptensive shock.terbutaline is a beta agonist drug mainly used in treatment of Bronchial asthma, as beta 2 receptors are also present on the blood vessel-action of adrenaline or beta 2 agonist causes vasodilation and hence causes fall in the blood pressure. Beta 2 receptors also present on the respiratory tracts, stimulation of beta 2 receptors on the airway by adrenaline or terbutaline causes bronchiodilation. Hence causes relief in asthma. Sudden withdrawal of the terbutaline can precipitate the acute attack of asthma.

Answer 2)among the given options beta blockers are used for treatment of angina. As beta blockers reduces the heart rate, it will decreases cardiac demand of oxygen, of which cardiac muscles are already deprived. Beta blockers are contraindicated in asthma, as they can cause bronchospasm and leads to acute attack of asthma.
