Questions: 4. A controllable risk factor for heart attack is: age genetics homocysteine inadequate exercise 5. A stroke is also known as: ecchymosis apoplexy cardiac arrhythmia

4. The answer is the last one: inadequate exercise.

Explanation:

• Age: This is not a controllable risk factor. As people age, their risk of heart attack naturally increases, but age itself cannot be controlled or changed.
• Genetics: This is also not a controllable risk factor. Genetic predisposition to heart disease is inherited and cannot be altered.
• Homocysteine: While elevated homocysteine levels can be a risk factor for heart disease, they are influenced by genetics and diet. However, they are not as directly controllable as lifestyle factors like exercise.
• Inadequate exercise: This is a controllable risk factor. Regular physical activity can significantly reduce the risk of heart attack by improving cardiovascular health, lowering blood pressure, and helping to maintain a healthy weight.

5. The answer is the second one: apoplexy.

Explanation:

• Ecchymosis: This refers to a discoloration of the skin resulting from bleeding underneath, typically caused by bruising. It is not related to a stroke.
• Apoplexy: This is an older term historically used to describe what we now know as a stroke, which is a sudden loss of brain function due to a disturbance in the blood supply to the brain.
• Cardiac arrhythmia: This refers to an irregular heartbeat and is related to heart function, not a stroke.
