closed drainage system

-Jackson-pratt drain -hemovac drain may be connected to an electrical suction or built-in reservoir

color classification of open wounds

-R: red-protect -Y: yellow-cleanse -B: black-debride -mixed wound: contains components of RY&B wounds

water

-accounts for between 50% and 60% of adults total weight -2/3 of body water is contained within the cells (ICF) -the remainder of body water is extracellular fluid, body fluids -acts as solvent, aids digestion

factors affecting body temp

-circadian rhythms -age and gender -physical activity -state of health -environmental temperature

Nurse Practice Acts

-define legal scope of nursing practice -create state board of nursing to make and enforce rules and regulation -define important terms and activities in nursing, including legal requirements and titles for RNs and LPNs - established criteria for the education and licensure of nurses

phases of wound healing

-hemostasis-vessels constrict and clotting begins -inflammatory-white blood cells move to wound -proliferation-granulation tissue is formed -maturation-collagen is remodeled, forms scar

goals of nursing research

-improve care in clinical setting -study ppl and nurse process: education, policy development, ethics, nursing history -develop greater autonomy and strength as a profession -provide evidence-based nursing practice

wound complications

-infection -hemorrhage -dehiscence(wound separates) and evisceration(protrusion) -fistula formation

minerals

-inorganic elements found in all body fluids and tissues -some function to provide structure in the body, others help regulate body processes -contained in ash that remains after digestion -macrominerals include calcium, phosphorus, magnesium -microminerals include iron, zinc, manganese, and iodine

fats

-insoluble in water and blood -composed of carbon, hydrogen, and oxygen - 95% of lipids in diet are triglycerides -most animal fats are saturated -most vegetable fats are unsaturated -digestion occurs largely in small intestine -most concentrated source of energy in diet -RDA not established, 20-35% total calorie intake

nursing process for bowels

-inspection -auscultation -percussion -palpation (deep palpation is performed by advanced medical personal)

assessing blood pressure

-listening for korotkoff sounds w/ stethoscope -first sound is systolic -change or cessation of sound occurs: diastolic pressure - brachial artery and popliteal artery are commonly used

The Nursing Process

-one of major guidelines for nursing practice -helps nurses implement their roles -integrates art and science of nursing -allows nurses to use critical thinking and clinical reasoning -defines the areas of care that are within the domain of nursing

Vitamins

-organic compounds needed by the body in small amounts -most are active in form of coenzymes -classified as water soluble or fat soluble -absorbed through intestinal wall (small intestine) directly into bloodstream -needed for metablolism

major classifications of hypertension

-primary (essential): characterized by an increase above normal in both systolic and diastolic pressures -secondary : caused by another disease condition like kidney disease, aorta disorders, or adrenal cortex disorders

heat production

-primary source is metabolism -hormones, muscle movements, exercise increase metabolism -thyroid hormone and shivering also increase heat production - energy production decreases and heat production increases

establishing an effective nurse-patient relationship

-reduce anxiety through therapeutic communication, teaching, and acceptance -remember that the patient has concerns and needs other medical ones -communicate with the patient as an individual -take time to learn about the patient being admitted -provide for the family participation in all aspects of care

protein

-required for formation of all body structures -based on amino acid composition -animal proteins are complete, plant proteins are incomplete -RDA for adults is 0.8g/kg

types of knowledge

-science (observing, identifying, describing, investigating, and explaining events and occurences that are perceived in world) -philosophy (the study of wisdom, fundamental knowledge, and the processes used to develop and construct on perception on life) -process (a series of actions, changes, or functions intended to bring about a desired result)

measurement of pressure ulcer

-size of wound -depth of wound -presence of undermining, tunneling, or sinus tract(all on wound bed)

stages of pressure ulcers

-stage1: nonblanchable erythema of intact skin -stage2: partial-thickness skin loss -stage3: full-thickness skin loss; not involving underlying fascia( epidermis and dermis) -stage4: full-thickness skin loss with extensive destruction (epidermis, dermis, and subcutaneous) -unstageable: base of ulcer covered by slough and/or eschar in wound bed

carbs

-sugars and starches -organic compounds composed of carbon, hydrogen, and oxygen -lactose is an animal source -most abundant and least expensive -classified as simple or complex sugars -converted to glucose for transport through blood -50-100g needed daily to prevent ketosis

sources of knowledge

-traditional ( passed down from generation to generation) -authoritative- comes from an expert, accepted as truth based on person's perceived expertise -scientific (obtained through the scientific method-research)

Nursing is recognized as profession based on what criteria

-well defined body specific and unique knowledge -strong service orientation -recognized authority by a professional group (ANA) -code of ethics -professional organization that sets standards -ongoing research -autonomy and self-regulation
