‘Aseptic non – touch technique (ANTT) and wound care’

• What is the main focus of the ANTT and wound care workbook?

  To gain an understanding of ANTT and wound care skills.
• What is a wound?

  A wound is a tear or break in the skin.
• What system is the skin a part of?

  The integumentary system.
• What are the components of the integumentary system?

  The skin, hair, nails, glands, and nerves.
• What are the three main functions of the skin?

  Protection, sensation, and temperature regulation.
• How does the skin protect the body?

  By preventing injury and blocking microorganisms.
• What role do nerve endings in the skin play?

  They allow us to identify touch, pain, and temperature.
• What is the hypodermis?

  A layer of fatty tissue that holds the skin to the muscle.
• What are the two main layers of the skin?

  The epidermis and the dermis.
• What is the epidermis?

  The outermost layer of the skin that does not contain blood vessels or nerve endings.
• How often does the epidermis regenerate?

  About every 2 to 4 weeks.
• Where is the epidermis thicker?

  On our hands and feet.
• What is the function of the dermis?

  It helps the skin maintain its shape and contains nerves and blood vessels.
• What happens when the dermis and epidermis are separated?

  The flow of waste and nutrients is obstructed, leading to fluid collection and blister formation.
• What can a wound affect?

  All layers of the skin and even the muscle.
• How can wounds occur?

  They can be intentional or caused by trauma, circulatory problems, or moisture from bodily fluids.
• What are some common types of wounds identified in children?

  Dog bites, cuts, burns/scalds, and surgical wounds.
• What are the four stages of wound healing?

  Haemostasis, inflammation, proliferation, and remodeling.
• What occurs during the haemostasis stage?

  Platelets clump together to form a plug to stop bleeding.
• What is the duration of the inflammation stage?

  Days.
• What happens during the inflammatory phase?

  Localized swelling occurs as blood vessels leak transudate, and healing cells move to the wound site.
• What are the signs of inflammation during wound healing?

  Swelling, heat, pain, and redness.
• What is interstitial fluid?

  Fluids that surround and bathe cells, facilitating nutrient exchange.
• What is the role of dendritic cells in the inflammatory response?

  They activate helper T-cells and phagocytose particles.
• What is the duration of the proliferation stage?

  Weeks.
• What happens during the remodeling stage?

  The fibers laid down in the proliferation stage are organized to form a new dermis.
• What factors can affect wound healing?

  Poor nutritional status, lack of sleep, pain, anxiety, and infection.
• What is primary intention in wound healing?

  When the layers of skin can be brought together to close the wound.
• What is secondary intention in wound healing?

  Wounds that are left open to heal due to tissue loss.
• What distinguishes acute wounds from chronic wounds?

  Acute wounds are recent, while chronic wounds do not heal as expected.
• What defines a clean wound?

  A surgical wound that is not inflamed or infected.
• What are the signs of an infected wound?

  Redness, swelling, pain, discharge, and heat.
• What is the importance of wound assessment?

  To determine the wound's appearance, drainage, and tissue viability for proper care.
• What is the key principle of ANTT?

  To prevent microbial contamination of key parts and sites.
• How does aseptic technique differ from sterile technique?

  Aseptic technique aims to prevent microorganisms, while sterile technique aims for total freedom from them.
• Why is ANTT important in healthcare?

  It helps prevent hospital-acquired infections (HAIs).
• What are the four key principles of ANTT?

  Always wash hands, use non-touch technique, touch non-key parts with confidence, and take appropriate precautions.
• What is the role of handwashing in ANTT?

  It is essential for preventing contamination and should not be replaced by gloves.
• What is a key part in ANTT?

  The part of the equipment that must remain sterile and only contact other key parts or sites.
• What is a key site in ANTT?

  The area on the patient that must be protected from microorganisms.
