Question 1

Which of the following best describes the main difference between regeneration and fibrosis during tissue repair?

Accepted Answer

Regeneration restores original tissue function, while fibrosis replaces tissue with scar tissue that lacks original function.

Question 2

A patient suffers a deep cut that damages both the epidermis and dermis. Which of the following best describes the process that will occur during tissue repair?

Accepted Answer

Both regeneration and fibrosis will occur, with regeneration restoring the epidermis and fibrosis forming scar tissue in the dermis.

Question 3

Which of the following is NOT a general component of all tissues?

Accepted Answer

Blood plasma

Question 4

Which tissue type has the highest regenerative capacity?

Accepted Answer

Epithelial tissue

Question 5

During the inflammatory stage of tissue repair, which of the following events occurs FIRST?

Accepted Answer

Release of inflammatory chemicals that increase blood vessel permeability

Question 6

Which of the following is a function of the skin?

Accepted Answer

Acts as a barrier to pathogens

Question 7

A burn patient is assessed using the 'Rule of Nines.' If the entire left arm and the anterior trunk are burned, what percentage of the body surface area is affected? (Assume the anterior trunk is 18% and each arm is 9% total.)

Accepted Answer

$$9\% + 18\% = 27\%$$

Question 8

Which of the following best describes the structure of the epidermis?

Accepted Answer

A stratified squamous epithelium composed of multiple layers of keratinocytes

Question 9

Which epidermal cell type is responsible for producing the pigment melanin?

Accepted Answer

Melanocytes

Question 10

Which of the following is a function of the dermis?

Accepted Answer

Provides strength and elasticity to the skin due to collagen and elastic fibers

Question 11

Which of the following is an example of an epidermal derivative and its general function?

Accepted Answer

Hair, which provides protection and sensory input

Question 12

A patient presents with yellowing of the skin (jaundice). Which change in skin color is most likely associated with this condition?

Accepted Answer

Increased bilirubin in the blood

Question 13

Which of the following best explains why elderly individuals are more prone to skin tears and bruising?

Accepted Answer

The dermis thins and loses elasticity with age, reducing protection and support for blood vessels.

Question 14

Which of the following is a complication associated with third-degree burns?

Accepted Answer

Loss of fluid and increased risk of infection

Question 15

Which of the following best describes the function of Langerhans cells in the epidermis?

Accepted Answer

They act as immune cells, detecting and presenting antigens to T cells.

Question 16

Which of the following is a characteristic of connective tissue that distinguishes it from epithelial tissue?

Accepted Answer

Connective tissue has a large amount of extracellular matrix.

Question 17

Which of the following best describes the process of inflammation in tissue repair?

Accepted Answer

It is the body's initial response to injury, involving increased blood flow, capillary permeability, and migration of white blood cells to the area.

Question 18

Which of the following is a correct pairing of a tissue type and a sample function?

Accepted Answer

Muscle tissue: contraction to produce movement

Question 19

Which of the following best explains why cartilage heals more slowly than skin?

Accepted Answer

Cartilage is avascular, so nutrients and cells required for repair must diffuse from surrounding tissues.

Question 20

A patient with a genetic disorder has defective collagen fibers in their connective tissue. Which of the following symptoms would most likely be observed?

Accepted Answer

Weakness and reduced elasticity in skin, tendons, and ligaments
