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 A
Explanation
Choice A Reason:
Norepinephrine is a key neurotransmitter released by the sympathetic nervous system during the “fight-or-flight” response. It plays a crucial role in preparing the body to respond to stress by increasing heart rate, blood pressure, and blood flow to muscles, as well as dilating the airways. These physiological changes are essential for coping with acute stress.
Choice B Reason:
Cortisol is a hormone released by the adrenal glands in response to stress, but it is primarily associated with the hypothalamic-pituitary-adrenal (HPA) axis rather than the sympathetic nervous system. While cortisol contributes to the body’s overall stress response by increasing blood sugar levels and suppressing the immune system, it is not the primary mediator of the acute “fight-or-flight” response.
Choice C Reason:
ACTH (adrenocorticotropic hormone) is a hormone produced by the pituitary gland that stimulates the adrenal glands to release cortisol. It is part of the HPA axis and plays a role in the body’s long-term stress response, but it is not directly involved in the immediate activation of the sympathetic nervous system.
Choice D Reason:
Glucagon is a hormone produced by the pancreas that raises blood glucose levels by promoting the breakdown of glycogen to glucose in the liver. While it can be involved in the body’s response to stress by ensuring an adequate supply of glucose, it is not a primary mediator of the acute stress response mediated by the sympathetic nervous system.
Correct Answer is C
Explanation
Choice A Reason:
The sympathetic nervous system (SNS) is responsible for the “fight or flight” response, which prepares the body to respond to perceived threats. One of the primary effects of SNS activation is an increase in heart rate. This is achieved through the release of catecholamines like adrenaline, which stimulate the heart to pump more blood to vital organs and muscles.
Choice B Reason:
Another effect of SNS activation is an increase in blood glucose levels. This occurs because the body needs more energy to respond to stress. The SNS stimulates the liver to release glucose into the bloodstream, ensuring that muscles and other tissues have enough energy to function effectively during a stressful situation.
Choice C Reason:
The correct answer is that SNS activation does not increase GI motility and movement. In fact, it has the opposite effect. During a “fight or flight” response, the body prioritizes functions that are critical for immediate survival, such as increased heart rate and blood flow to muscles. As a result, non-essential functions like digestion are slowed down. The SNS decreases GI motility and movement to divert energy and blood flow to more critical areas.
Choice D Reason:
SNS activation also leads to an increase in blood pressure. This is achieved by constricting blood vessels and increasing the force of heart contractions. The purpose of this response is to ensure that enough blood and oxygen are delivered to essential organs and muscles during a stressful situation.
