Correct Answer is B

Explanation

A. Appear yellow: Yellow skin is often due to jaundice (bilirubin accumulation) or carotene deposits, not keratinization.

B. Are hardened and water-resistant: Keratinization involves the production of keratin, making the epidermis tough and water-resistant to protect against dehydration and external damage.

C. Appear cyanotic: Cyanosis is a bluish discoloration due to hypoxia, not keratinization.

D. Have been replaced by connective tissue: Keratinized epidermal cells are still part of the skin, whereas connective tissue replacement occurs in scarring or wound healing.

A. The pain receptors in the dermis have been destroyed B. The melanin within the skin acts as a pain reliever C. The burn site has not yet become infected D. He is immobile and not moving the injured site

Correct Answer is A

Explanation

A. The pain receptors in the dermis have been destroyed: Third-degree burns penetrate the entire dermis and often destroy nerve endings, reducing the ability to feel pain at the site of injury.

B. The melanin within the skin acts as a pain reliever: Melanin is responsible for skin pigmentation and does not have analgesic properties.

C. The burn site has not yet become infected: The presence or absence of infection does not determine pain perception in third-degree burns.

D. He is immobile and not moving the injured site: While movement may exacerbate pain, third-degree burns often result in reduced pain due to nerve destruction.
