Study Notes
Clubbing and Nail Care
- Clubbing is a change in the angle between the nail and nail base of more than 180 degrees.
Innate Immunity
- NK cells and neutrophils are involved in innate immunity, not T cells, which aid in adaptive immunity.
- NK cells are not a type of macrophage.
Sebaceous Glands
- Sebaceous glands produce sebum.
Wound Healing
- An acute wound is not defined as one that requires various treatments and takes a long time to heal.
- Interferon is effective against viruses.
Lymphatic System
- The spleen filters blood.
- Lymph fluid flows through the lymphatic system as a result of a pressure gradient that forces fluid into the lymphatic capillaries.
- The right lymphatic duct drains vessels from the right arm, right side of the head and neck, and right side of the chest.
Pressure Areas
- There are four stages of pressure areas.
- A stage one pressure area is an area of persistent, non-blanchable redness when compared to the surrounding skin.
Infections and Prevention
- Impetigo is a contagious infection that requires strict handwashing guidelines to prevent spread.
- Pyrogens are an example of cytokines, which act on the hypothalamus to increase body temperature during times of invasion by pathogens.
Viruses and Reproduction
- Viruses need the host cell to reproduce because they have no organelles and cannot participate in normal cellular processes.
Assessment and Risk
- The Braden scale is used to assess people who are at risk of pressure areas.
- When doing an assessment of the hair, asking about changes in appetite or diet is important because it can influence nutritional intake, which is evident in the condition of the hair.
Leukocytes and Maturation
- T lymphocytes mature in the thymus.
- When doing a skin assessment, it is important to consider turgor because... (incomplete information)
Lymphatic System
