knowledge assessment II Flashcards
thoracic cage is composed of
sternum, clavicle, scapulae, 12 vertebrae, and 12 pairs of ribs
three main compartments of thoracic cage
airways
blood vessels
interstitinum
mediastinum
heart, great vessels, lymph nodes, nerves, fat
additional structures within the thorax
thymus, distal part of trachea, and most of the esophagous
thoracic muscles
- intercostals
- transverse thoracic
- subcostal
blood supply within thorax
arterial: thoracic aorta, subclavian, brachial, axillary
venous: various veins
pulmonary arteries, pulmonary veins
pulmonary arteries
carry deoxygenated blood from the right side of the heart to each lung
pulmonary veins
return oxygenated blood from lungs to the left side of the heart
anterior thoracic landmarks
begin at suprasternal (jugular notch)
costal angle
angle between ribs at the costal margins located at bottom of sternum at the xiphoid process
typically 90 degrees or less
why wouldn’t you palpate ribs posteriorly?
harder to do as a result of overlying musculature so easiest to assess at vertebrae
midsternal line
anterior in center of sternum
midclavicular line
in middle of clavicle or collar bone
anterior axiallary line
aligns where arms closed
vertebral line
middle of vertebrae posteriorly
scapular line
starts closest to vertebral line right where scapula starts
midscapular line
starts in middle of scapula
posterior axillary line
runs vertically along posterior edge from top of axilla between anterior and posterior axiallary lines
the right lung has how many lobes?
3
the left lung has how many lobes?
2
RML is ausculatated using an
anterior approach, although a small portion can be ausculatated laterally
- may be difficult with women due to breast tissue
horixontal fissue
divides RUL and RML of lung
RML extends from
4th rib at sternal border to the 5th rib at midaxillary line
the lower border of right lung is
higher than the left because the liver displaces the lung tissue upward
the left lung is
narrower than right because the heart and pericardium bulge to the left displacing the lung tissue
the base of the lungs refers to
very bottom of lung fieldsd
apex of lungs refers to
very top of lungs
components of respiratory tracts
nasal cavity
eipglottis
nasopharynx
oropharynx
laryngeal pharynx
larynx and vocal cords
esophagous
trachea
right and left lung
right and left bronchus
terminal bronchiole
diaphargm
the trachea bifurcates at the
caring into right and left mainstem bronchi which turn into smaller bronchi and continue to separate until becoming terminal bronchioles which give rise to alveolar sacs lined by alveoli
the right mainstem broncus is
shorter, wider, and more vertical than left
the upper respiratory tract is responsible for
moisturizing inhaled air and filtering noxious particles
what triggers respiration
automatic process initiated by pons and medulla
main trigger in respiration
increased CO2 levels in blood
other triggers of respiration
decreased oxygen levels, increased acidity, certain medication (drug overdoses, opiates, sedatives) causing hypoventilation or apnea, brain injury (hyperventilation)
inspiration
- diaphragm contract and flattens pulling lungs downward
- thorax and lungs elongate increasing in length
- external intercostal muscles open ribs and lift sternum
- increase in anteroposterior diamter fo thorax causing 500-800 mL of air to enter lungs of adults
with increased thoracic size
pressure within the thorax is less than pressure in the atmosphere causing influx of atmospheric air to enter the lungs
expiration
- diaphragm, internal intercostal muscles, abdominal muscles relax
- pressure in lungs is greater than atmosphere
- air is pushed out and chest and abdomen return to relaxed position
effective breathing depends on sufficient
nerve innervation, muscle excursion, strength
pts with conditions effecting the spinal cord (especially c3-5) may need
ventilator support
extreme obesity can limit
chest wall expansion therefore compromising breathing
progressive loss of muscle function can
limit ability to ventilate and cough
(muscular dystrophy)
respiratory issues in older adults
- decline in respiratory strength
- lungs lose elasticity
- decreased flexibility in rib cartilage
- bone density decreases
- decreased AP ratio (barrel chest)
- diminished respiratory volume
immobility in older adults creates risk for
- atelectasis (airway collapse)
- reduced air exchange
- hypoxia
- hypercapnia
- acidosis
older people having a reduced cough and gag reflex puts them at higher risk for
aspiration of secretions
aspiration pneumonia
risk of postoperative respiratory complications in older adults due to
impaired cough reflex, weaker muscles, and decreased respiratory capacity
stress increases what in older adults
respiratory complications
genetic patterns of inheritance increase risk for respiratory disorders such as
cystic fibrosis
alpha-1 antitrypsin deficiency (associated w/ early onset emphysema)
asthma
cultural and ethnic variability of respiratory illnesses
TB
smoking
risk factors of TB
HIV +
immigrants
homeless
drug and alc abuse
ABC
airway breathing circulation
acute shortness of breath priorty assessment
assess airway, RR, PR, BP, and O2 sat
auscultate lungs for possible abnormalities
administer O2 as orderd
administer bronchodilators as ordered
elevate head of bed
important factors for those with acute SOB
keep patient calm as anxiety increases respiratory decline
as O2 level in blood and tissues decrease,
pts become more dyspneic and cyanotic causing insufficient blood supply to brain resulting in confusion and decreasing level of consciousness
priority urgent assessment #3 for acute SOB
- may be unable to cooperate fully
- ausculatate when turning client
- prioritize subjective data
- ask only pertinent Qs related to situation
- cluster interventions
- assess when client is more relaxed
assessment of risk factors for respiratory conditions
past medical history
lifestyle and personal habits
occupational history
environmental exposures
medications
family hx
teaching and health promotion for respiratory conditions
smoking cessation
prevention of occupation exposure
prevention of asthma
immunizations
all smokers should be
asked at every appointment about readiness to stop as smoking has been linked to lung cancer, emphysema, chronic bronchitis, CV disease, and oropharyngeal cancer
asthma triggers
tobacco smoke
dust
molds
furred and feathered animals
cockroaches
pests
have you ever been diagnosed with a respiratory disease or condition such as asthma, bronchitis, emphysema, pneumonia or lung cancer?
you want to ask this as certain diseases like COPD have long term effects that result in slow progressive decline in function, asthma symptoms may occur at any age and improve or worsen over time, pneumonia usually has acute onset and resolves itself after meds
common chest symptoms
- chest pain
- dyspnea
- orthopnea
- paroxysmal nocturnal dyspnea
- cough
- sputum
- wheezing
- functional abilities
- older adults
- cultural factors
general appearance of respiratory examination
observe pt posture and positioning
posture is upright and ANOx3/4, facial expression relaxed
abnormal: pts in tripod position (common in COPD or those w respiratory distress)
inspection of posterior chest
moving around to inspect posterior chest, inspect and compare AP to assess overall shape of thoracic cage, observe spontaneous chest expansion
palpation of posterior chest
palpate chest for tender areas
use fingertips starting above scapula over the lung apex and progress from sid eto side compare findings bilaterally, palpate for crepitus
abnormal: lesions, lumps, massess, crepitus (air filled massess underneath skin)
tactile fremitus posterior chest
evaluates density of lung tissue
- place palmar base or ulnar surface of hand on patients chest above scapula and ask patient to say 99, vibrations of air in bronchial tree are transmitted allowing assessment of intensity and symmetry of fremitus from L + R lungs
percussion in posterior chest
can help discover if tissue is air filled, fluid filled, or solid, usually interpreted in combination with otehr examination techniques
percuss anteriorly, posteriorly, and laterally
ausculatation posterior chest
ask pt to breathe deeply through mouth
ID breath sounds by listening for intensity, quality, pitch, and duration of inspriation compared with expiration
vesicular breath sounds
soft, low pitched and found over fine airways near site of air exchange (lung periphery)
bronchovesicular sounds
found more centrally, over major bronchi that have fever alveoli
bronchial breath sounds are
loud high pitched and found over trachea and larynx
common to hear crackles on inspiration with first deep breath (if heard ask patient to cough)
inspection of anterior chest
use same techniques
inspect chest wall for deformities or asymmetry between right and left sides, assess size of costal angle, observe for use of accessory muscles to breathe, no barrel chest, inspect ICSs for retractions or bulging
palpation of anterior chest
Palpate the anterior chest for tenderness, masses, or lesions. Begin at the lung apices and move from side to side, ending below the costal angle and moving laterally to the midaxillary line-No tenderness, masses, or lesions should be observed
percussion anterior chest
precuss anterior and lateral chest in the ICSs
avoid percussion over bone and/or breast tissue
percussion in anterior chest should sound
resonant in lungs
auscultation of anterior chest
auscultate the trachea and anaterior and lateral lung fields
listen to lung apices
listen down to the 6th ICS bilaterally or when breath sounds become absent signalling end of lung fields
bronchial breath sounds are audible over
the trachea
bronchovesicular sounds are heard over the
2nd-3rd ICSs to the right and left of sternum over the bronchi
vesicular sounds are heard in
other areas of lung fields
making clinical decisions regarding respiratory conditions
- analyze lab and diagnostic testing
- prioritize hypotheses and take action
- analyzing changing findings
- interprofessional collaboration w respiratory therapy
- plan the care
- evaluate outcomes
RR: elevated WBC count may indicate
infection like pneumonia
analysis of sputum sample may help ID
causative microorganism
arterial blood gas is a direct measure of
blood O2 , CO2, and acid balance
radiographic studies can provide
objective evidence of disease process within thorax and lungs
PET scans
measure the metabolic rate of various body tissues, providing info about presence and stage of a malignancy
if PET scans revealed adrenal metasisis the potentially lethal surgery would not benefit pt
Acute shortness of breath is a medical emergency. Immediate assessments are necessary. What is the priority assessment the nurse would make with a client who has acute shortness of breath?
A. Administer inhalers
B. Administer oxygen
C. Raise the head of the bed
D. Auscultate lungs
D. auscultate
acute SOB; immediate auscultation then o2 is administered and inhalers may be given then head of bed elevated
nurses measure nutritional status by
- taking height and weight measurements
- monitoring I&Os
- measuring lab values
body function is affected by intake of
primary nutrients
nutrients
- carbohydrates
- proteins and amino acids
- lipids and fatty acids
- vitamins and minerals
- supplements
- fluid and electrolytes
carbohydrates
main source of bodily energy
simple and complex
should comprise 45-65% of caloric intake
proteins and amino acids
proteins function in cell structure and tissue maintenance
amino acids are building blocks of protein
total amount needed per day increases when ill
lipids and fatty acids
- triglycerides, sterols, and phospholipids
- maintain total body function (promote absorption of fat soluble vitamins A, D, E, K
- saturated, unsaturated, and monosaturated
- HDLs and LDLs
clinical significance of lipids and fatty acids
excess leads to atherosclerosis, stroke, and MI
increase in obesity
USDA and AHA recommend how much fat intake
20-35% of caloric intake
vitamins and minerals
- foundation of cellular structures
- key role in nutrient metabolism
- vitamin B and D are commonly lacking
- minerals of importance: iron, zinc, calcium
water
body loses 1500-2800mL/day
requires minimum intake of 1500 mL/day to maintain excretion of metabolic waste
sodium and potassium
essential
limited to 2300 mg/day
medications commonly prescribed for individuals w/ chronic illness can lead to
alteration in K+ levels
abnormal K+ levels can lead to lethal cardiac dysrhythmias
utilize MyPlate guidelines mad eby USDA and HHS
- consider food choices that meet personal, cultural, and budget preferences
- recognize that eating is part of lifestyle, social system, and way of living
goals for nutritional guidelines
encourage individuals to meet nutritional needs
choose variety of options
pay attention to portions
pregnancy and lactation
additional 300-500 calories per day
emphasis on protein
vitamin and mineral supplement may be required
vitamin b
neccessary for those trying to get preganant at least 1 month before conception and 2-3 months after
infants, children, and adolescents
protein is ciritcal
milk:
- under 2: whole milk
- 2-5: low fat milk
older adults have decreased
taste and third drive
poor dentition
BMR decline
high risk of malnutrition and dehydration
factors influencing nutrition
culture
religion
geographic location
food and fluid preferences
eating patterns, digestions, allergies
shopping resources and skills
kitchen facilities and ability to prepare food
meaning behind food and feeding
social patterns at means
GI structures and dentititon
subjective cues in nutritional assessment
- deficits develop over time
- during stress or trauma caloric need increases
- ask pt nutritional preferences
- if pt in unable to make decisions, consider consult
nurses role in nutritional assessment
- look at developmental, social, economic, and cultural facotrs
- complete nutrition screening (risk factor assessment, comp. nutritional history, physical exam, calculated measurements, serial lab values)
- pt teaching
main causes of malnutrition
poverty, alcoholism, hospitalization, aging, and eating disorders
alcohol recommeded intake
1 drink/day - females
2 drink/day - males
if pt is at risk for altered nutrition this should be done
- food records
- food frequency questionnaires
- direct observation
comprehensive physcial assessment for nutrition
body time - small, average, large
general appearance
swallowing
BMI (18.5-24.9)
CBC
can exclude anemias from nutritional deficiencies like iron, folate, and b12
serum albumin
longer half life protein than prealbumin
inflammation will decrease serum albumin making it an unreliable serum marker for malnutrition
prealbumin
half life is much shorter (2 days) and its total body pool is smaller and is a more reliable indicator of pt nutritional status
prealbumin is degraded by
kidneys so any renal dysfunction causes increase in its serum levels
transferrin
iron deficiency states (chronic blood loss anemia) levels of transferrin are elevated because of increase amount of iron absorption
levels increase w renal failure
oral contraceptives or estrogen formulas also alter levels
rentinol binding protein
vitamin a and zinc are vital in proper functioning of RBP and hence any abnormalities in levels of these micronutrients affect levels of RBP in serum
creatinine and blood urea nitrogen
- nitrogen balance means more loss than intake
nitrogen balance is measured w concentration of urea in urine
diagnosis or hypothesis: UNDERWEIGHT
description

interventions
have pt keep food diary and record every intake
teach reading of food labels, weight 2x/week, iteach increased intake of fruits and vegetables
fluid imablance
description
increased fluid usually due to impaired heart and circulation or low excretion by kidneys
assessment
altered electrolytes, elevated creatinine, decreased hematocrit, and hemoglobin, weight gain

steps of kidney filtration
- glomerulus
filters small solutes from blood - proximal convoluted tubules
reabsorbs ions, water, and nutrients; removes toxins and adjusts filtrate pH - descending loop of henle
aquaporins allow water to pass from filtrate into interstitial fluid - ascending loop of henle
reabsorb na+ and cl- from filtrate into the interstitial fluid - distal tubule
selectively secretes and absorbs different ions to maintain blood pH and electrolyte imbalance - collecting duct
reabsorbs solutes and water from filtrate
GI considerations for older adults
- decreased saliva and stomach acid produciton
- difficulty swallowing, absobing, and digesting
- motility and peristalsis decrease
- dentition changes
- financial constraints
- less likely to feel abdominal pain
- fat accumulates in lower abdomen making assessment more difficult
- liver decreases in size and function
- renal function declines
- diminished thirst sensation
