Skin Integrity – Ch 32 Flashcards
What are the functions of the skin
+ Protective barrier against injuries – mechanical, thermal, physical
+ prevent loss of moisture
+ immune system organ
+ production of vitamin D
+ temperature regulator
+ sensory organ
What are the factors that affect scanned
+ Developmental – babies and Jerry’s of thin skin
+ fluid loss/dehydration
+ weight – excessively thin or obese persons
+ nutrition
+ diseases – autoimmune, jaundice etc.
Categories/types of wins
+ Intentional/unintentional
+ open/closed
+ acute/chronic
+ pressure injuries
+ contusion/abrasion/laceration/avulsion
Open wound – explain
+ Intentional or unintentional trauma
+ skin surface is broken
+ Includes intentional surgical cuts
+ Increased risk for infection, delayed healing may occur
Closed wound – explain
+ Flow, force, or strain
+ trauma such as a fall, assault, motor vehicle crash
+ skin surface not broken
+ soft tissue damage Dash internal injury or hemorrhage may occur
Acute wound – describe
+ Expected to progress through phases of normal healing
+ results in wound closure – surgical wound
Chronic wound – explain
+ Does not progress through normal, orderly, timely sequence of repair
+ often incorrectly treated
Four types of trauma wound to the skin
+ Contusion Dash bruise
+ abrasion Dash scraping top 1 to 2 layers of skin
+ Lazeration – cut by sharp objects – no skin as missing
+ avulsion - forcible tearing off of skin or other part of body, likely exposing muscles tendons and tissue
Three principles of dealing
+ primary intention
+ Secondary intention
+ tertiary intention
Explain primary intention of wound healing
Closing a word with staples, sutures, glue
Explain secondary intention of wound healing
+ Graduation present, waves that cannot be stitched causing a large amount of tissue loss
+ Pressure injuries
Explain tertiary intention of wound healing
+ Graduation present
+ wounds that cannot be stitched causing large amount of tissue loss
