A female student is driving to school when another driver nearly hits her. Her heart begins beating hard and fast as she becomes scared and aroused. Which of the following stages of the general adaptation syndrome is she experiencing?
Exhaustion
Adaptation
Alarm stage
Stage of resistance
The Correct Answer is C
Choice A Reason:
The exhaustion stage is the final phase of the general adaptation syndrome (GAS). It occurs when the body has been exposed to stress for a prolonged period and can no longer maintain resistance. Symptoms of exhaustion include fatigue, burnout, depression, and decreased stress tolerance. Since the student is experiencing an immediate response to a sudden stressor, this stage does not apply.
Choice B Reason:
Adaptation is not a specific stage in the general adaptation syndrome. The correct stages are alarm, resistance, and exhaustion. Therefore, this choice is incorrect.
Choice C Reason:
This is the correct answer. The alarm stage is the initial phase of the general adaptation syndrome, also known as the “fight-or-flight” response. During this stage, the body reacts to a stressor by activating the sympathetic nervous system, which leads to increased heart rate, rapid breathing, and heightened alertness. The student’s reaction to the near-miss accident fits this description perfectly.
Choice D Reason:
The stage of resistance is the second phase of the general adaptation syndrome. During this stage, the body attempts to adapt to the stressor and return to a state of balance. If the stressor persists, the body remains on high alert, but the initial shock of the alarm stage has passed. Since the student’s response is immediate and acute, it aligns with the alarm stage rather than the resistance stage.

Correct Answer is D
Explanation
Choice A Reason:
Fat necrosis occurs when fatty tissues are damaged, leading to the release of enzymes that break down fat cells. This type of necrosis is commonly seen in the pancreas and breast tissue, often due to trauma or pancreatitis. It is not typically associated with brain tissue.
Choice B Reason:
Coagulative necrosis is characterized by the preservation of the basic outline of the coagulated cells for a few days after cell death. This type of necrosis is usually seen in tissues affected by ischemia, such as the heart, kidneys, and adrenal glands. However, it is not the typical pattern of necrosis seen in brain tissue.
Choice C Reason:
Caseous necrosis is a form of cell death in which the tissue maintains a cheese-like appearance. It is most commonly associated with tuberculosis infections in the lungs. This type of necrosis is not typically seen in brain tissue.
Choice D Reason:
Liquefactive necrosis is the correct answer. This type of necrosis occurs when the tissue becomes soft and liquefied, often forming a pus-filled cavity. It is commonly seen in the brain due to ischemic injury or bacterial infections. The high lipid content and low structural support in brain tissue make it particularly susceptible to liquefactive necrosis.
Correct Answer is B
Explanation
Choice A Reason:
Vomiting is not a risk factor for a heart attack but rather a symptom that can occur during a heart attack. Risk factors are conditions or behaviors that increase the likelihood of developing a disease. Vomiting can be a sign of various conditions, including gastrointestinal issues or even a heart attack, but it does not contribute to the risk of having a heart attack.
Choice B Reason:
Hypertension, or high blood pressure, is a significant risk factor for heart attacks. It causes the heart to work harder than normal, leading to the thickening of the heart muscle and narrowing of the arteries. Over time, this increased workload can damage the arteries, making them more susceptible to blockages that can cause a heart attack. Managing blood pressure through lifestyle changes and medication is crucial in reducing the risk of heart attacks.
Choice C Reason:
Chest pain is a common symptom of a heart attack but not a risk factor. Risk factors are pre-existing conditions or behaviors that increase the likelihood of developing a disease. Chest pain, also known as angina, occurs when there is reduced blood flow to the heart muscle, often due to blockages in the coronary arteries. While chest pain indicates a potential heart problem, it is not a contributing factor to the development of a heart attack.
Choice D Reason:
Cell necrosis refers to the death of cells, which can occur during a heart attack when the blood supply to part of the heart muscle is blocked. This is a consequence of a heart attack rather than a risk factor. Risk factors are conditions or behaviors that increase the likelihood of developing a disease, whereas cell necrosis is a result of the disease process.
