Q: Which equation correctly represents the calculation of the total body surface area (TBSA) affected by burns using the 'rule of nines' for an adult?

$$TBSA = \text{Sum of percentages assigned to each affected region}$$

Question 1

Which of the following best describes the difference between gross and microscopic anatomy?

Accepted Answer

Gross anatomy studies structures visible to the naked eye, while microscopic anatomy examines structures that require magnification.

Question 2

A patient presents with a burn that affects the epidermis and part of the dermis, causing blistering and pain. Which type of burn is this?

Accepted Answer

Second-degree burn

Question 3

Which of the following is an example of negative feedback in homeostatic regulation?

Accepted Answer

Sweating to cool the body when overheated

Question 4

Which equation correctly represents the calculation of the total body surface area (TBSA) affected by burns using the 'rule of nines' for an adult?

Accepted Answer

$$TBSA = 	ext{Sum of percentages assigned to each affected region}$$

Question 5

Which of the following best describes the function of desmosomes in epithelial tissue?

Accepted Answer

They anchor adjacent cells together, providing mechanical strength.

Question 6

A tissue sample shows cells that are flat and arranged in multiple layers. Which type of epithelial tissue is this?

Accepted Answer

Stratified squamous epithelium

Question 7

Which of the following is a function of the subcutaneous layer (hypodermis)?

Accepted Answer

Insulation and energy storage

Question 8

Which statement correctly describes the difference between apocrine and eccrine sweat glands?

Accepted Answer

Apocrine glands secrete into hair follicles and are activated during emotional stress, while eccrine glands secrete directly onto the skin surface and are involved in thermoregulation.

Question 9

Which process is described by the equation $$	ext{Keratinization} = 	ext{Production of keratin by epidermal cells}$$?

Accepted Answer

Formation of a tough, protective layer in the skin

Question 10

A patient has a genetic disorder resulting in the absence of melanin production. What condition does this patient have?

Accepted Answer

Albinism

Question 11

Which of the following best describes the difference between loose and dense connective tissue?

Accepted Answer

Loose connective tissue has fewer fibers and more ground substance, while dense connective tissue has more fibers and less ground substance.

Question 12

Which of the following is NOT a function of the epidermis?

Accepted Answer

Insulation and energy storage

Question 13

Which cell junction allows the passage of ions and small molecules directly between adjacent cells?

Accepted Answer

Gap junction

Question 14

Which of the following best describes the process of apoptosis?

Accepted Answer

Programmed cell death that is a normal part of development and tissue homeostasis

Question 15

Which equation represents the relationship between the rate of sweat production ($$R) $$and body temperature ($$T) in $$thermoregulation?

Accepted Answer

$$R \propto (T - T_{set})$$

Question 16

Which of the following is a function of sebaceous glands?

Accepted Answer

Secretion of oily substance to lubricate and protect the skin

Question 17

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

Accepted Answer

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

Question 18

A patient is unable to absorb calcium efficiently due to lack of vitamin D. Which process is most directly affected?

Accepted Answer

Calcium absorption in the GI tract

Question 19

Which of the following is a characteristic of the stratum basale in the epidermis?

Accepted Answer

It contains stem cells that divide to produce new keratinocytes.

Question 20

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

Accepted Answer

They act as sensory receptors for touch.
