Question:
What is the primary difference between reversible and irreversible cellular injury?
Answer:
Reversible cellular injury refers to a situation where the cell can return to its normal state after
the stressor is removed. The cell may undergo changes such as swelling or fatty change, but it
can recover once homeostasis is restored. In contrast, irreversible injury leads to cell death, often
through necrosis or apoptosis. The hallmark of irreversible injury includes damage to the cell
membrane, mitochondrial dysfunction, and loss of the cell's ability to maintain homeostasis.
Rationale:
Reversible injury is often temporary and can be managed, while irreversible injury typically
results in cell death. This distinction is crucial in understanding the potential for recovery of
damaged tissues.
Question:
Which of the following is a characteristic feature of acute inflammation?
A) Chronicity of tissue damage
B) Presence of neutrophils
C) Fibrosis
D) Slow onset
Answer:
B) Presence of neutrophils
Rationale:
,Acute inflammation is characterized by the rapid onset of the inflammatory response, which
includes the influx of neutrophils to the site of injury. Neutrophils are the first responders to
acute tissue injury and play a critical role in combating infections and initiating repair.
Question:
Which of the following is the most common cause of acquired immunodeficiency?
A) Genetic mutations
B) HIV infection
C) Organ transplantation
D) Cancer
Answer:
B) HIV infection
Rationale:
HIV infection is a primary cause of acquired immunodeficiency. The virus targets CD4+ T
lymphocytes, leading to a weakened immune system and an increased susceptibility to
opportunistic infections. Genetic mutations, organ transplantation, and cancer can also affect
immunity, but HIV is the most common cause of acquired immunodeficiency.
Question:
Which of the following is a primary cause of left-sided heart failure?
A) Pulmonary hypertension
B) Myocardial infarction
C) Valvular stenosis
D) Renal artery stenosis
Answer:
B) Myocardial infarction
Rationale:
Myocardial infarction (MI) is one of the leading causes of left-sided heart failure. The damage to
the heart muscle from an MI impairs the left ventricle's ability to pump blood effectively, leading
to a backup of blood into the pulmonary circulation and symptoms of pulmonary edema.
,Question:
What is the primary pathophysiologic process involved in asthma?
A) Airway inflammation
B) Decreased pulmonary compliance
C) Pulmonary fibrosis
D) Airway obstruction due to mucus plugs
Answer:
A) Airway inflammation
Rationale:
Asthma is primarily characterized by inflammation of the airways, leading to
bronchoconstriction, mucus production, and airway hyperresponsiveness. While airway
obstruction may occur due to mucus plugs, the hallmark of asthma is inflammation, which leads
to the acute exacerbations seen in the disease.
Question:
Which of the following hormones is elevated in Graves’ disease?
A) Cortisol
B) Insulin
C) Thyroid hormone (T3 and T4)
D) Parathyroid hormone
Answer:
C) Thyroid hormone (T3 and T4)
Rationale:
Graves' disease is an autoimmune disorder that leads to hyperthyroidism, characterized by
elevated levels of thyroid hormones (T3 and T4). This overproduction of thyroid hormones
causes symptoms such as weight loss, heat intolerance, and tremors.
, 7Question:
Which of the following is the most common cause of acute renal failure?
A) Glomerulonephritis
B) Acute tubular necrosis (ATN)
C) Renal artery stenosis
D) Nephrolithiasis
Answer:
B) Acute tubular necrosis (ATN)
Rationale:
Acute tubular necrosis (ATN) is the most common cause of acute renal failure, often resulting
from ischemia or nephrotoxic substances that damage the renal tubules. This damage impairs
renal filtration and can lead to renal failure.
Question:
Which of the following conditions is characterized by demyelination of the central nervous
system?
A) Parkinson's disease
B) Multiple sclerosis
C) Alzheimer's disease
D) Huntington's disease
Answer:
B) Multiple sclerosis
Rationale:
Multiple sclerosis (MS) is an autoimmune disease in which the body's immune system attacks
the myelin sheath of neurons in the central nervous system, leading to impaired nerve conduction
and a variety of neurologic symptoms. The other diseases listed involve different
pathophysiologic processes.
