Question

question 13
a patient with an \infarction\ due to \stenosis\ leading to
ecrosis\ means that the patient has a:
blockage leading to new blood vessel formation
blockage leading to tissue death
hemorrhage leading to tissue death
tumor leading to new blood vessel formation

question 14
the medical term sy/stole actually means:
agent or nerve that enlarges the lumen of blood vessels
cardiac cycle phase where chambers contract raising blood pressure
abnormal or pathological condition of the blood
agent or nerve that narrows the lumen of blood vessels

question 15
a non - controllable risk factor for heart attack is:
obesity
smoking
age
alcohol

Explanation:

• Question 13: Stenosis is a blockage or narrowing. Infarction is tissue death due to lack of blood - supply caused by blockage. Necrosis also refers to tissue death. So, a patient with infarction due to stenosis leading to necrosis has a blockage leading to tissue death.
• Question 14: Systole is the phase of the cardiac cycle where the heart chambers contract, which raises blood pressure.
• Question 15: Obesity, smoking, and alcohol consumption can be controlled through lifestyle changes. Age is a non - controllable risk factor for heart attack as one cannot change their age.

Answer:

• Question 13: blockage leading to tissue death
• Question 14: cardiac cycle phase where chambers contract raising blood pressure
• Question 15: age
