Question 1 of 5
How does ephedrine act on the body?
Correct Answer: B
Rationale: The correct answer is B because ephedrine stimulates the release of norepinephrine from nerve endings, leading to increased sympathetic nervous system activity. This results in effects such as increased heart rate and blood pressure.
Choices A and C are incorrect because ephedrine does not directly act on alpha or beta-adrenergic receptor sites.
Choice D is incorrect because ephedrine primarily stimulates the release of norepinephrine, not dopamine.
Choices E, F, and G are not provided, but based on the mechanism of ephedrine action, they would also be incorrect.
