An obese diabetic teen is given a prescription for a low-calorie diet and exercise program. This is an example of:
Tertiary prevention
Disease treatment
Secondary prevention
Primary prevention
The Correct Answer is D
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.

Correct Answer is D
Explanation
Choice A: Calcium
Calcium plays a crucial role in various physiological processes, including muscle contraction, blood clotting, and nerve transmission. While calcium is essential for maintaining overall health, it is not directly associated with changes in blood pH. Calcium levels are tightly regulated by hormones such as parathyroid hormone (PTH) and calcitonin, but these do not significantly influence blood pH.
Choice B: Sodium
Sodium is a major extracellular electrolyte that helps regulate fluid balance, nerve function, and muscle contraction. Although sodium is vital for maintaining osmotic balance and blood pressure, it does not directly affect blood pH. Sodium levels are primarily controlled by the kidneys and hormones like aldosterone, which do not have a direct impact on the acid-base balance of the blood.
Choice C: Magnesium
Magnesium is involved in over 300 biochemical reactions in the body, including protein synthesis, muscle and nerve function, and blood glucose control. While magnesium is important for overall health, it does not have a direct role in altering blood pH. Magnesium levels are regulated by the kidneys and are essential for maintaining normal muscle and nerve function, but they do not directly influence the acid-base balance.
Choice D: Potassium
Potassium is a key intracellular electrolyte that plays a significant role in maintaining the acid-base balance of the blood. Changes in potassium levels can affect the pH of the blood. For example, hyperkalemia (high potassium levels) can lead to acidosis, while hypokalemia (low potassium levels) can lead to alkalosis. Potassium helps regulate the hydrogen ion concentration in the blood, which directly impacts the pH. Therefore, potassium is the electrolyte most closely associated with changes in blood pH.
Correct Answer is C
Explanation
Choice A Reason:
Psychosocial factors, such as stress, beliefs, and expectations, can influence drug response to some extent. However, they are not the primary reason for the most common variations in drug response. These factors might affect how a patient perceives the effectiveness of a drug, but they do not significantly alter the pharmacokinetics or pharmacodynamics of the drug itself.
Choice B Reason:
Drug receptor sites can vary between individuals, affecting how well a drug binds and exerts its effect. While this can contribute to differences in drug response, it is not the most common cause. Variations in receptor sites are often due to genetic differences, which can influence the efficacy and potency of a drug.
Choice C Reason:
This is the correct answer. The metabolism of drugs is the most common cause of variation in drug response among individuals. Differences in metabolic rates can be attributed to genetic factors, age, liver function, and the presence of other medications. These factors affect how quickly a drug is broken down and eliminated from the body, leading to variations in drug levels and responses.
Choice D Reason:
Hypersensitivity potential refers to the likelihood of an individual having an allergic reaction to a drug. While this can cause significant differences in drug response, it is not the most common reason for variations. Hypersensitivity reactions are relatively rare compared to metabolic differences.
