What is an example of a risk factor in a patient with a heart attack?

Choice A Reason:

Tertiary prevention focuses on managing and mitigating the complications of an existing disease to prevent further deterioration. For obesity, this might involve interventions like bariatric surgery or intensive management of comorbid conditions such as diabetes or cardiovascular disease. In this scenario, the goal is not to prevent the onset of disease but to manage its long-term effects and improve quality of life.

Choice B Reason:

Disease treatment refers to the direct management of a diagnosed condition. For a diabetic teen, this could include medications like insulin or metformin, regular monitoring of blood glucose levels, and other medical interventions to control diabetes. While a low-calorie diet and exercise are important components of diabetes management, they are more aligned with preventive measures rather than direct treatment.

Choice C Reason:

Secondary prevention aims to detect and address a disease early in its course to prevent progression. This might include screening programs, early interventions, and lifestyle modifications for individuals at high risk of developing a condition. In the context of diabetes, secondary prevention could involve regular blood glucose monitoring and early dietary changes to prevent the progression from prediabetes to diabetes.

Choice D Reason:

Primary prevention involves measures taken to prevent the onset of a disease before it occurs. This includes lifestyle interventions such as a healthy diet, regular physical activity, and maintaining a healthy weight. For an obese diabetic teen, a prescription for a low-calorie diet and exercise program is aimed at preventing further weight gain and reducing the risk of developing additional health complications, making it a primary prevention strategy.

Choice A: Size

Muscular hypertrophy refers to the increase in the size of muscle cells12. This process typically occurs as a result of strength training, where the muscles are subjected to stress and damage, leading to the repair and growth of muscle fibers. The increase in muscle cell size enhances muscle strength and mass, making it a key goal for athletes and bodybuilders.

Choice B: Vacuoles

Vacuoles are membrane-bound organelles found in cells, primarily involved in storage and transport of substances3. While vacuoles play important roles in cellular function, they are not directly related to muscular hypertrophy. The primary change in muscular hypertrophy is the increase in muscle cell size, not the number or size of vacuoles.

Choice C: Types

Muscle cells can be categorized into different types, such as slow-twitch (Type I) and fast-twitch (Type II) fibers4. However, muscular hypertrophy does not involve a change in the types of muscle cells. Instead, it focuses on the growth and enlargement of existing muscle fibers, regardless of their type.

Choice D: Number

An increase in the number of muscle cells is referred to as hyperplasia, which is different from hypertrophy. Hyperplasia involves the formation of new muscle cells, whereas hypertrophy involves the enlargement of existing muscle cells. Current evidence suggests that hypertrophy, rather than hyperplasia, is the primary mechanism for muscle growth in response to strength training.
