Internal And External Wounds

Explanation
An abrasion is a type of external wound that occurs when the skin is scraped or rubbed against a rough surface, causing the top layer of skin to be removed. This can result in pain, bleeding, and sometimes the formation of a scab. Ulcer, diarrhea, and bruise are not types of external wounds. Ulcer refers to a sore that develops on the skin or mucous membranes, diarrhea is a condition characterized by frequent loose or watery stools, and a bruise is a discoloration of the skin caused by bleeding underneath the surface.

Explanation
An internal wound refers to an injury that occurs beneath the surface of the skin, meaning that the skin itself remains intact. This can happen when there is trauma to the underlying tissues, such as muscles, organs, or blood vessels, without breaking the skin. It is important to recognize internal wounds as they may not be immediately visible, but can still cause significant damage and require medical attention. Therefore, the statement "An internal wound is when the surface of the skin is intact but the underlying tissue is injured" is true.

Explanation
An external wound refers to a break in the skin's surface where blood may come through the tear, resulting in external bleeding. This can occur due to various reasons such as cuts, scrapes, or puncture wounds. The term "external" implies that the injury is visible on the outside of the body rather than internal. It is important to clean and treat external wounds properly to prevent infection and promote healing.

Explanation
The given statement does not make logical sense. A job for internal and external wounds cannot be a teacher. Therefore, the correct answer is False.

Explanation
Keeping an external wound clean is an essential part of the treatment process. When a wound is clean, it reduces the risk of infection and promotes faster healing. Cleaning the wound helps remove dirt, debris, and bacteria that may have entered the wound, preventing further complications. It also helps to keep the wound moist and prevents it from drying out, which can impede the healing process. Therefore, it is crucial to keep an external wound clean as part of its treatment.
