A patient has a heart attack that leads to progressive cell injury that causes cell death with severe cell swelling and breakdown of organelles and release of cellular debris. What term would the nurse use to define this process?
Necrosis.
Apoptosis.
Adaptation.
Pathologic calcification.
The Correct Answer is A
Choice A Reason:
Necrosis is the term used to describe the death of cells or tissues through injury or disease, particularly when it involves severe cell swelling, breakdown of organelles, and release of cellular debris. This process is typically uncontrolled and results from factors such as lack of blood flow (ischemia), toxins, or trauma. In the context of a heart attack, necrosis occurs due to the lack of oxygen and nutrients, leading to cell death and tissue damage.
Choice B Reason:
Apoptosis is a form of programmed cell death that occurs in a controlled and regulated manner. It is a natural process that helps maintain homeostasis by eliminating damaged or unnecessary cells without causing inflammation. Unlike necrosis, apoptosis involves cell shrinkage, chromatin condensation, and DNA fragmentation, but it does not result in the release of cellular debris.
Choice C Reason:
Adaptation refers to the changes that cells undergo in response to stress or adverse conditions to survive and maintain function. These changes can include hypertrophy, hyperplasia, atrophy, and metaplasia. Adaptation is a reversible process and does not involve cell death or the breakdown of cellular components.
Choice D Reason:
Pathologic calcification is the abnormal deposition of calcium salts in tissues. It can occur in areas of necrosis (dystrophic calcification) or in normal tissues due to hypercalcemia (metastatic calcification). While pathologic calcification can be associated with cell injury and death, it is not the primary process described in the scenario of a heart attack leading to cell death with severe swelling and breakdown of organelles.

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.
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.
