A patient is taking an inducer medication. The provider added a new medication. What is the effect of the inducer medication on the newly added medication?
Increases the blood level of the newly added medication.
Decreases the blood level of the newly added medication.
Increases the half-life of the newly added medication.
Doesn’t have any effect on new medications.
The Correct Answer is B
Choice A Reason:
Inducer medications do not increase the blood level of newly added medications. Instead, they enhance the activity of enzymes that metabolize drugs, leading to a faster breakdown and lower concentration of the new medication in the bloodstream. This can result in reduced efficacy of the newly added medication.
Choice B Reason:
Inducer medications increase the activity of enzymes, particularly those in the cytochrome P450 family, which are responsible for drug metabolism. This increased enzyme activity accelerates the breakdown of the newly added medication, thereby decreasing its blood level and potentially reducing its therapeutic effect. For example, rifampin is a well-known inducer that can significantly lower the levels of drugs metabolized by CYP3A4.
Choice C Reason:
Inducer medications do not increase the half-life of newly added medications. On the contrary, by enhancing the metabolic activity of enzymes, they typically reduce the half-life of the new medication. This means the drug is broken down and eliminated from the body more quickly.
Choice D Reason:
Inducer medications do have a significant effect on new medications. They alter the metabolism of drugs by increasing the activity of metabolic enzymes, which can lead to decreased blood levels and reduced effectiveness of the new medication. Ignoring this interaction can result in subtherapeutic drug levels and treatment failure.

Correct Answer is D
Explanation
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: Atrophy
Atrophy refers to the reduction in size or wasting away of an organ or tissue due to a decrease in cell size or number. This can occur due to various reasons such as disuse, lack of nutrition, or loss of nerve supply. While atrophy involves the shrinkage of cells, it does not directly result in cellular death. Instead, it is a form of cellular adaptation to adverse conditions.
Choice B: Proliferation
Proliferation is the process by which cells grow and divide to produce more cells. This process is essential for growth, development, and tissue repair. Proliferation leads to an increase in the number of cells and is the opposite of cellular death. It is a tightly regulated process that ensures the maintenance and regeneration of tissues.
Choice C: Mutation
Mutation refers to changes in the DNA sequence of a cell. These changes can occur due to errors during DNA replication, exposure to radiation, or chemical mutagens. While mutations can lead to various outcomes, including cancer, they do not directly cause cellular death. Instead, mutations can alter the function of genes and proteins, potentially leading to uncontrolled cell growth or other cellular dysfunctions.
Choice D: Death
Apoptosis is a form of programmed cell death that occurs in multicellular organisms. It is a highly regulated process that allows the body to remove damaged or unnecessary cells without causing harm to surrounding tissues. Apoptosis involves a series of biochemical events leading to characteristic cell changes and eventual death. This process is crucial for maintaining cellular homeostasis and preventing the development of diseases such as cancer.
