After suffering a heart attack, a middle-aged man is counseled to attend physical therapy. This is an example of:
Disease treatment.
Tertiary prevention.
Secondary prevention.
Primary prevention.
The Correct Answer is B
Choice A Reason:
Disease treatment refers to the management and care of a patient to combat a disease or condition. This includes interventions aimed at curing the disease, alleviating symptoms, or preventing complications. While physical therapy can be part of disease treatment, in the context of a heart attack, it is more accurately described as a form of tertiary prevention.
Choice B 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. Physical therapy after a heart attack is a classic example of tertiary prevention, as it aims to improve the patient’s quality of life, enhance physical function, and prevent further cardiac events.
Choice C 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. In the case of heart disease, secondary prevention might involve regular monitoring of blood pressure and cholesterol levels to detect and manage risk factors early.
Choice D Reason:
Primary prevention aims to prevent the onset of disease before it occurs by reducing risk factors and promoting healthy behaviors. This includes lifestyle changes such as a healthy diet, regular exercise, and smoking cessation to prevent the development of heart disease in the first place. Physical therapy after a heart attack does not fall under primary prevention, as it is an intervention after the disease has already occurred.

Correct Answer is C
Explanation
Choice A: Alkalosis
Alkalosis refers to a condition where the blood pH is higher than the normal range (above 7.45). In this case, the pH is 7.25, which indicates an acidic environment rather than an alkaline one. Therefore, alkalosis is not the correct answer.
Choice B: Respiratory
Respiratory acidosis or alkalosis is determined by the levels of PaCO2. In respiratory acidosis, PaCO2 is elevated, while in respiratory alkalosis, PaCO2 is decreased. Here, the PaCO2 is 20 mm Hg, which is below the normal range, indicating a respiratory component. However, the primary issue is not respiratory because the HCO3- is also significantly low, pointing towards a metabolic cause.
Choice C: Metabolic
Metabolic acidosis is characterized by a low pH and a low HCO3- level. In this case, the pH is 7.25, and the HCO3- is 10 mEq/L, both of which are below the normal ranges. This indicates that the primary acid-base imbalance is metabolic acidosis.
Choice D: Acidosis
Acidosis refers to a condition where the blood pH is lower than the normal range (below 7.35). The given pH of 7.25 confirms that the patient is experiencing acidosis. However, this choice alone does not specify whether it is metabolic or respiratory acidosis.
Choice E: With Compensation (Being Compensated)
Compensation refers to the body’s attempt to return the pH to normal by adjusting the levels of PaCO2 or HCO3-. In this case, the low PaCO2 suggests that there is a respiratory compensation for the metabolic acidosis. However, the primary imbalance remains metabolic acidosis.
Correct Answer is B
Explanation
Choice A Reason:
Atrophy refers to the reduction in size or wasting away of an organ or tissue due to a decrease in cell size or number. It is not a type of cell death but rather a process of cell shrinkage and loss of function. Therefore, it does not directly relate to the damage caused to nearby cells.
Choice B Reason:
This is the correct answer. Apoptosis is a form of programmed cell death that occurs in a controlled and regulated manner. It allows for the removal of damaged or unnecessary cells without causing an inflammatory response or damage to surrounding tissues. During apoptosis, cellular components are neatly packaged into vesicles called apoptotic bodies, which are then phagocytosed by neighboring cells or immune cells, preventing the release of harmful substances.
Choice C Reason:
Necrosis is a form of traumatic cell death that results from acute cellular injury. It often leads to the uncontrolled release of cellular contents, causing inflammation and damage to surrounding tissues. This process can be detrimental to nearby cells and is generally considered more harmful than apoptosis.
Choice D Reason:
Lysis refers to the breaking down or destruction of cells, often due to external factors such as toxins, infections, or immune responses. Like necrosis, lysis can result in the release of cellular contents into the surrounding environment, leading to inflammation and damage to nearby cells.
