A woman undergoes a mammogram test for cancer screening. This is an example of:
Primary prevention
Secondary prevention
Disease treatment
Tertiary prevention
The Correct Answer is B
Choice A 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 vaccinations. Mammograms, however, are not used to prevent breast cancer from occurring but to detect it early.
Choice B Reason:
Secondary prevention aims to detect and address a disease early in its course to prevent progression. Mammograms are a classic example of secondary prevention because they are used to screen for breast cancer in women who do not yet show symptoms2. Early detection through mammograms can lead to earlier treatment, which can significantly improve outcomes and reduce mortality rates.
Choice C Reason:
Disease treatment refers to the direct management of a diagnosed condition. For breast cancer, this could include surgery, chemotherapy, radiation therapy, and other medical interventions. Mammograms are not a treatment but a diagnostic tool used to detect the presence of cancer.
Choice D Reason:
Tertiary prevention focuses on managing and mitigating the complications of an existing disease to prevent further deterioration. For breast cancer, this might involve rehabilitation, ongoing treatment to prevent recurrence, and palliative care. Mammograms are used for early detection, not for managing complications of already diagnosed cancer.

Correct Answer is ["A","B","C","E"]
Explanation
Choice A Reason:
Chronic stress can significantly impact mental health, leading to conditions such as depression. The persistent activation of the stress response system, particularly the release of cortisol, can alter brain function and structure, contributing to mood disorders. Studies have shown that prolonged exposure to stress hormones can lead to changes in the brain that are associated with depression.
Choice B Reason:
Impaired cognitive function is another consequence of chronic stress. Elevated levels of cortisol over an extended period can damage the hippocampus, a region of the brain involved in memory and learning. This can result in difficulties with concentration, memory, and decision-making. Chronic stress has been linked to cognitive decline and an increased risk of neurodegenerative diseases.
Choice C Reason:
Chronic stress can also affect the immune system, leading to autoimmune diseases. The continuous activation of the stress response can cause immune dysregulation, where the body’s immune system mistakenly attacks its own tissues. This can result in conditions such as rheumatoid arthritis, lupus, and other autoimmune disorders.
Choice D Reason:
Overactive immune function is not typically associated with chronic stress. Instead, chronic stress often leads to a weakened immune response, making the body more susceptible to infections and illnesses. Therefore, this choice is incorrect.
Choice E Reason:
Cardiovascular disease is a well-documented consequence of chronic stress. The persistent release of stress hormones like adrenaline and cortisol can lead to increased blood pressure, heart rate, and the formation of artery-clogging deposits. These changes can increase the risk of heart disease, heart attacks, and strokes.
Correct Answer is C
Explanation
Choice A Reason:
The sympathetic nervous system (SNS) plays a role in regulating body temperature. It does this by controlling the dilation and constriction of blood vessels in the skin, which helps to dissipate or conserve heat as needed. Therefore, the statement that the SNS regulates body temperature is correct.
Choice B Reason:
The SNS is crucial in regulating the cardiovascular system. It increases heart rate and the force of heart contractions, and it also causes vasoconstriction, which raises blood pressure. This statement is accurate and does not indicate a need for further teaching.
Choice C Reason:
This is the correct answer. The SNS generally inhibits digestive functions during the “fight-or-flight” response. It reduces blood flow to the digestive organs, decreases peristalsis, and inhibits digestive secretions. Therefore, the statement that the SNS regulates digestive functions is incorrect and indicates a need for further teaching.
Choice D Reason:
The SNS is responsible for the “fight-or-flight” response, which prepares the body to respond to perceived threats. This includes increasing heart rate, dilating airways, and mobilizing energy stores. This statement is correct and does not indicate a need for further teaching.
