Which of the following molecules is likely to accumulate in any dead or dying tissues?

• Calcium
• Uric acid
• Melanin
• Protein - ANSWER- a. Calcium

Rationale: When calcium pumps fail due to mitochondrial

injury, calcium accumulates in the cytoplasm and contributes to irreversible cellular injury and cell death.

Why is carbon monoxide exposure a life-threatening condition?

• Carbon monoxide causes the release of toxic amounts of iron

from the tissues. 1 / 4

• | P a g e

• Inhalation of carbon monoxide interferes with oxygen

diffusion in the lungs.

• Carbon dioxide removal from the tissues is inhibited.
• Carbon monoxide binds to hemoglobin and prevents normal

oxygen transport to tissues. - ANSWER- d. Carbon monoxide binds to hemoglobin and prevents normal oxygen transport to tissues.

Which of the following molecules accumulates in liver cells as a result of alcohol abuse?

• Fat (lipids)
• Water
• Iron
• Protein - ANSWER- a. Fat (lipids)

What are the primary factors contributing to oncosis from hypoxic injury?

• Increase in ATP production and potassium movement out of

the cell

• Accumulation of lipids and pigments in the cell
• Injury to the endoplasmic reticulum and Golgi apparatus 2 / 4

• | P a g e

• Decrease in ATP production and sodium movement into the

cell - ANSWER- d. Decrease in ATP production and sodium movement into the cell

Pathologic hyperplasia can lead to:

• phagocytosis.
• stem cell activation.
• enlargement of the uterus.
• metaplasia. - ANSWER- d. metaplasia.

Which of the following is a form of metaplasia that can occur in the human body?

• Epithelial cells of the bronchial lining are replaced with

collagenous connective tissue.

• Adipose cells are replaced by cells that cannot store lipids.
• Squamous epithelial cells of the esophageal lining are

replaced by glandular cells similar to those lining the stomach.

• Liver cells are replaced by squamous epithelial cells. -

ANSWER- c. Squamous epithelial cells of the esophageal lining are replaced by glandular cells similar to those lining the stomach. 3 / 4

Free radicals directly injure cells by each of the following

mechanisms except:

• DNA fragmentation.
• lipid peroxidation.
• activation of lysosomal enzymes.
• alteration of proteins. - ANSWER- c. activation of lysosomal

enzymes.

Restoration of oxygen to oxygen-deprived tissues results in:

• chemical injury.
• establishment of normal cell metabolism.
• reperfusion injury.
• hypoxic injury. - ANSWER- c. reperfusion injury.

The process of cellular atrophy may be accomplished through which of the following processes?

• Decreased cell division
• Loss of fluid
