Exposure to ultraviolet (UV) radiation

Question 10

A burn patient is assessed using the 'rule of nines.' What is the primary purpose of this rule?

Accepted Answer

To estimate the percentage of body surface area affected by burns

Question 11

Which mechanism of glandular secretion involves the release of products by exocytosis without loss of cellular material?

Accepted Answer

Merocrine secretion

Question 12

Which skin gland is responsible for producing oily secretions that lubricate the skin and hair?

Accepted Answer

Meissner's corpuscle

Question 16

Which of the following correctly describes the two layers of the dermis?

Accepted Answer

Papillary layer: loose areolar connective tissue; Reticular layer: dense irregular connective tissue

Question 17

A Langerhans cell in the epidermis primarily functions as:

Accepted Answer

An immune cell involved in antigen presentation

Question 18

Which of the following best describes the difference between 1st, 2nd, and 3rd degree burns?

Accepted Answer

1st degree: affects only epidermis; 2nd degree: affects epidermis and dermis; 3rd degree: affects epidermis, dermis, and deeper tissues

Question 19

Which of the following best explains the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands secrete products onto epithelial surfaces

Question 20

A patient with a severe burn covering 36% of their body surface area is at risk for fluid loss. Using the rule of nines, calculate the percentage of body surface area affected if both legs and the anterior trunk are burned. (Each leg = 18%, anterior trunk = 18%)

$$	ext{Total Burned Area} = 18\% + 18\% + 18\% = 54\%$$

Accepted Answer

54%
