5%of cases of HTN are secondary to adrenal disorders e.g. Hyperaldosteronism Conn’s). LVH is a pathological effect of HTN. ACTH increases corticosteroid synthesis in the adrenal glands- glucocorticoids and aldosterone.
Hyperaldosteronism results in hypertension.
Hypoxia due to respiratory failure results in stimulation of carotid and aortic bodies which results in tachycardia, hypertension and hyperventilation. Methydopa is a centrally acting anti-hypertensive agent

Paradoxical hypertension has been reported after iv use therefore (e) is True (A-Z P339)

doesn't it do a similar thing to clonidine so you get a wee bit of hypertension initially then the hypotensive effect kicks in
