sitting
head erect neck and vertebral colun in striahgt alignment, body weight evenly distrubuted on buttocks and thighs, thighs parallel and i horizontal plane. both feet supported on floor 1"-2" maintained between edge of seat and poplitelal space on posterior surface of knee --pressure on popliteal artery or nerve decreases circulation and impairs nerve functhion

encourage patient to assist with move if possible
keep the weight to be lifted as close to the body as possible--place object in same plane as lifter and close to center of gravity for balance.
bend at knees: helps maintain center of gravity and uses stronger leg muscles to do the lifting. avoid twisting --can overload spine and cause serious injury.
tighten abdominal muscles and tuck the pelvis -- provides balance and helps protect the back.
maintain the trunk erect andknees bent so that multiple groups work together in coordinated manner.
assess for correct body alignment and pressure after each transfer.---wash hands
how can illness effect nutritional status
short term illness: cold/ no taste flu/ not hungry
chronic illness: cancer- HIV- low apetite for longer periods at risk of malnutrion
P&I: oral suplements like ensure, InG feedings, total parental nutrition TPN
NPO: nothing by mouth
how can a nurse improve the nutrition status of a patient lacking apetite?
assessment: ask their food preferences, the may hate hamburger meat or chicken. if they are just not hungry alter feedings to fit their appetite better. temperature of food. make sure they have their teeth in!
if room smells due to dirty commode.
meds to increase appetite
name two meds that stimulate appetite
Megace and Periactin
patient with physical impairments such as
blind clients: foster independence by offering favorite foods, relate food on plate like a clock.
immobilized patients: can cause calcium to leave the bones and increase the risk for fracture. excess calcium in blood can lead to bladder and kidney stones. encourage protein intake for tissue repair,increased fluid intake, ROM to reduce skin breakdown.
swallowing difficulties: increases risk for aspiration. may need SLP -service location protocol-to help with evaluation and management of eating. need to be upright seated position to eat, or HOB -head of bed elevated.
dysphagia: need smaller bites and eat more slowly. may need changed in the consistency of liquids -thin nectar like honey-like and spoon thick.
other reason for patients not eating properly
decreased financial resources. often only able to afford purchasing less expensive items leading to malnutrition.
what are some of the community resources that are available to clients?
churches hospitals, WIC, special groups,private dietician, food stamps.
advise to purchase generic brands, beans, frozen veggies, instead of fresh. supplements.
how does the mind effect how someone eats-phsycological influence?
social affair, sit i there with them while they eat if they are alone and won't eat. discuss with family what food they could bring to get them to eat.
how does evaluation impact nursing care of a client with a nutritional problem?
make sure that the nutritional goal is being achieved.
ask why they are not eating. maybe they want to have company while eating.
