Question

CD58 Beta adrenergic receptor antagonists

A. Seldom causes inhibition of lipolyisis
B. Causes inhibition of gluconeogenesis caused by adrenergic stimulation following hypoglycaemia
C. Does not mask the signs of hypoglycaemia
D. Sudden cessation is not associated with rebound effects
E. There is no evidence of cardiac protection for high risk patients pre-operatively

Answer 1

Beta adrenergic receptor antagonists, or beta-blockers, have multiple effects on the body including decreasing glucose uptake by cells, inhibiting insulin secretion, and enhancing lipolysis. However, there is no evidence of cardiac protection for high-risk patients pre-operatively.

Step-by-step explanation:

Beta adrenergic receptor antagonists, also known as beta-blockers, have various effects on the body. They decrease the glucose uptake by cells, except for the brain and red blood cells. They inhibit the secretion of insulin and enhance lipolysis in adipose tissue. They increase blood pressure, basal metabolic rate, and act as smooth muscle relaxants. However, there is no evidence of cardiac protection for high-risk patients pre-operatively.
