$$\text{Total Burn Area} = 9\% \times \text{Number of Regions Burned}$$

Question 1

Which of the following best describes the function of the Haversian canal in compact bone?

Accepted Answer

It houses blood vessels and nerves that supply bone cells.

Question 2

Ed's lower legs were severely blistered and red after a sunburn. According to burn classification, what degree of burn did Ed most likely experience?

Accepted Answer

Second degree

Question 3

Which of the following is NOT a primary function of the skeletal system?

Accepted Answer

Thermal regulation

Question 4

Why are injuries to connective tissue generally considered more serious than those to epithelial tissue?

Accepted Answer

Connective tissue is vascularized, increasing the risk of infection.

Question 5

A dull scalpel causes a jagged wound during surgery. What type of wound is this most likely to be classified as?

Accepted Answer

Laceration

Question 6

Cartilage types are distinguished primarily by which of the following characteristics?

Accepted Answer

The quantity and composition of matrix fibers

Question 7

Stratified epithelia are most likely to be found in which of the following locations?

Accepted Answer

Where abrasion and friction can wear off the surface

Question 8

Which stem cell is responsible for producing cells found in cartilage?

Accepted Answer

Chondroblast

Question 9

A patient presents with a puncture wound. Compared to an abrasion, why is the risk of infection greater?

Accepted Answer

Puncture wounds penetrate deeper, introducing pathogens into vascularized connective tissue.

Question 10

Which of the following best explains why thermal burns are NOT classified by degree?

Accepted Answer

Because temperature varies and causes confusion in classification.

Question 11

If a tissue sample shows cells tightly packed with little extracellular matrix and is avascular, which tissue type is most likely being observed?

Accepted Answer

Epithelial tissue

Question 12

Which of the following is a hematopoietic function of bone?

Accepted Answer

Production of red blood cells in the marrow

Question 13

A patient has a third-degree burn. Which of the following best describes the tissue damage?

Accepted Answer

Full thickness of skin is destroyed; tissue may appear white or charred and is often painless.

Question 14

Which equation best represents the percentage of body surface area affected by burns using the 'Rule of Nines'?

Accepted Answer

$$	ext{Total Burn Area} = 9\% 	imes 	ext{Number of Regions Burned}$$

Question 15

Which of the following is most likely to be found in the central cavity of an osteon (Haversian system)?

Accepted Answer

Blood vessels and nerves

Question 16

Which connective tissue cell type is most likely to be destroyed and not replaced after injury?

Accepted Answer

Connective tissue cells generally have limited regenerative capacity compared to epithelial cells.

Question 17

Which of the following best describes the difference between a lesion and a laceration?

Accepted Answer

A lesion is a general term for any abnormal tissue change, while a laceration is a specific type of wound with jagged edges.

Question 18

Which of the following statements about the matrix of cartilage is correct?

Accepted Answer

It is distinguished by the quantity and composition of its fibers.

Question 19

Which of the following is a real-world consequence of damage to stratified epithelial tissue?

Accepted Answer

Increased susceptibility to infection due to loss of protective barrier.

Question 20

A patient with a bone fracture is at risk for which of the following complications due to the vascular nature of bone tissue?

Accepted Answer

Increased risk of infection due to blood vessel exposure
