Cardiovascular System Disorders Questions and Answers

Answer: B

Arteriosclerosis means progressive degeneration of arteries.

Arteriosclerosis is the thickening, hardening and loss of elasticity of the arterial walls. It develops slowly over years, often with ageing, high blood pressure and atherosclerosis, which makes it a progressive degenerative change.

Arteries do not regenerate in this condition, which rules out both 'regeneration' options. The change is gradual rather than rapid, which rules out 'rapid degeneration'.

Answer: C

The signs of heart attack are (i) and (ii), so the answer is Both (i) and (ii) are correct.

A heart attack typically causes chest pain, a crushing or squeezing pain that may spread to the left arm, jaw or back. The body's stress response also brings on sweating with wet, clammy skin, along with breathlessness, nausea and anxiety.

Joint pain is a feature of arthritis and other joint disorders, and yellow discoloration of the eyes is jaundice, a sign of liver disease or haemolysis. Neither is a sign of heart attack, so the options including (iii) or (iv) are wrong.
