A 17-year-old college-bound student receives a vaccine against an organism that causes meningitis. This is an example of:
Tertiary prevention.
Primary prevention.
Disease treatment.
Secondary prevention.
The Correct Answer is B
Choice A Reason:
Tertiary prevention involves measures taken to reduce the impact of an ongoing illness or injury that has lasting effects. This includes rehabilitation and efforts to prevent further complications or deterioration. Vaccination, however, is aimed at preventing the disease before it occurs, which does not align with the concept of tertiary prevention.
Choice B Reason:
Primary prevention refers to actions taken to prevent the onset of disease before it occurs. Vaccination is a classic example of primary prevention because it aims to protect individuals from contracting diseases by stimulating the immune system to recognize and fight specific pathogens. In this case, the meningococcal vaccine helps prevent meningitis, making it a primary preventive measure.
Choice C Reason:
Disease treatment involves managing and caring for a patient to combat a disease or condition. This includes interventions aimed at curing the disease, alleviating symptoms, or preventing complications. Vaccination does not fall under disease treatment because it is a preventive measure rather than a therapeutic one
Choice D Reason:
Secondary prevention focuses on early detection and prompt intervention to prevent the progression of a disease. This includes screening tests and early treatment of conditions to halt or slow their progression. Vaccination, however, is intended to prevent the disease from occurring in the first place, which is not the goal of secondary prevention.

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.
Correct Answer is ["A","C"]
Explanation
Choice A Reason:
Acidosis is indicated by a pH lower than the normal range of 7.35-7.45. In this case, the patient’s pH is 7.3, which confirms acidosis. Acidosis can be caused by either respiratory or metabolic factors, but the low pH alone confirms the presence of acidosis.
Choice B Reason:
Compensation refers to the body’s attempt to return the pH to normal by adjusting the levels of CO2 or HCO3-. In this case, the HCO3- level is within the normal range (22-26 mEq/L), indicating that there is no metabolic compensation occurring. Therefore, this choice is incorrect.
Choice C Reason:
Respiratory acidosis is indicated by an elevated PaCO2 level, which is higher than the normal range of 36-44 mmHg. The patient’s PaCO2 is 48 mmHg, suggesting that the acidosis is due to respiratory factors. This is consistent with the patient’s history of smoking and symptoms of respiratory distress.
Choice D Reason:
Alkalosis is indicated by a pH higher than the normal range of 7.35-7.45. Since the patient’s pH is 7.3, which is below the normal range, this indicates acidosis, not alkalosis. Therefore, this choice is incorrect.
Choice E Reason:
Metabolic acidosis is indicated by a low HCO3- level. In this case, the patient’s HCO3- level is within the normal range (25 mEq/L), indicating that the acidosis is not metabolic. Therefore, this choice is incorrect.
