Question 1

Which of the following are the two most distinct layers of skin?&#10;A) stratum germinativum and stratum corneum&#10;B) epidermis and dermis&#10;C) subcutaneous and stratum corneum&#10;D) integument and stratum germinativum

Accepted Answer

The skin has two distinct layers-the outer, or surface, layer is the epidermis and the inner layer is the dermis.

Question 2

Which layer of skin contains the stratum germinativum and stratum corneum?&#10;A) epidermal layer&#10;B) adipose tissue&#10;C) dermal layer&#10;D) hypodermal layer

Accepted Answer

The epidermis can be divided into five layers. Two of the layers are the deeper stratum germinativum and the more superficial stratum corneum.

Question 3

Which skin layer supports the dermis?&#10;A) epidermal layer&#10;B) hypodermis&#10;C) adipose tissue&#10;D) cutaneous membrane

Accepted Answer

The dermis sits on a subcutaneous layer called the hypodermis.

Question 4

Which of the following best describes hyperthermia?&#10;A) an elevation in body temperature; the body simply cannot cool itself&#10;B) a decrease in body temperature caused by a prolonged exposure to cold&#10;C) the normal range of body temperatures&#10;D) an increase in body temperature generally caused by an infection

Accepted Answer

Hyperthermia refers to an elevation of body temperature caused by the inability of the body to get rid of excess heat; the body simply cannot cool itself.

Question 5

A blackhead is formed when this gland becomes blocked by accumulated oil and cellular debris.&#10;A) ceruminous&#10;B) eccrine&#10;C) sebaceous&#10;D) apocrine

Accepted Answer

Sometimes, the sebaceous glands become blocked by accumulated sebum and other debris. When the sebum is exposed to the air and dries out, it turns black, forming a blackhead.

Question 6

Alopecia is most likely to occur in a ________.&#10;A) tanned patient&#10;B) cyanotic patient&#10;C) patient who is being treated with anticancer drugs&#10;D) patient with vitiligo

Accepted Answer

A second common cause of hair loss is related to drug toxicity, as with chemotherapy or radiation therapy. Anticancer drugs are so cytotoxic that they often destroy hair-producing epithelial cells.

Question 7

This condition is exhibited when no melanin is secreted.&#10;A) melanoma&#10;B) vitiligo&#10;C) alopecia&#10;D) albinism

Accepted Answer

If the melanocytes completely fail to secrete melanin, the skin, hair, and the colored part of the eye (iris) are white. This condition is referred to as albinism.

Question 8

Why do older people tend to feel cold?&#10;A) There is a decrease in the amount of adipose tissue under the skin.&#10;B) There is an increase blood flow to the skin, resulting in excess cooling.&#10;C) Metabolic rate increases with age.&#10;D) Keratinization decreases with age.

Accepted Answer

The amount of adipose tissue in the subcutaneous layer decreases, resulting in increased and wrinkled skin that has a decreased ability to maintain body temperature. The person tends to feel cold.

Question 9

Why does the skin become dry, coarse, and itchy in the older person?&#10;A) There is a decrease in the amount of adipose tissue.&#10;B) There is an increase in the blood flow to the skin.&#10;C) There is an increased fragility of the skin.&#10;D) There is decreased sebaceous gland activity in the skin.

Accepted Answer

Sebaceous gland activity decreases, resulting in dry, coarse, itchy skin.

Question 10

Which patient is most likely to require an escharotomy?&#10;A) a person who is cyanotic&#10;B) a person with severe digital clubbing&#10;C) a severely burned patient&#10;D) a person with drug-induced urticaria

Accepted Answer

Because eschar can have such serious consequences, it is often slit (escharotomy) to allow expansion of the burned area or removed to rid the body of a source of toxin.
