Answer 1

41. The autonomic nervous system controls the central and peripheral nervous system. Option A is the correct answer.

42. Dobutamine primarily acts on stimulating beta-1 receptors. Option C is the correct answer.

43. The heart is self-controlled and does not depend on the brain to beat. The cardiovascular center in medulla regulates the blood pressure but not the heart function. Option D is the correct answer.

44. The risk of damage to vessel walls is a potential consequence of hypertension. This may lead to stroke. Option A is the correct answer

45. The nurse should assess lying, sitting and standing blood pressures to monitor for adverse effects of the therapy. Option D is the correct answer.
