Nurs 242 Midterm Module 1-5 Flashcards
Goals for client with oxygenation and circulation problems:
- maintain patent airway
- improving comfort and ease of breathing
- maintaining or improving pu,monary ventilation and oxygenation
- maintaining or improving tissue perfusion
- improving ability to participate in physical activities
- preventing risk associated with oxygenation prbs: skin & tissue breakdown, syncope, acid-base imbalances,
Interventions of nurse to maintain normal respiration’s of clients include:
- positioning client to allow maximum chest expansion
- encouraging or providing frequent changes in position
- encourage ambulation
- measures that promote comfort, such as giving analgesic
- providing fluids and humidification
- encouraging deep breathing & coughing
what positions give patient maximum chest expansion when confined to a bed?
Semi-fowlers
High Fowlers
Dyspneic pts often sit in bed and lean over their overbed tables, usually with a pillow for support this is called
orthopenic position (an adaptation of high fowlers)
what are the further advantages for orthopenic position instead over high fowlers
because organs not pressing on diaphragm, client can press on lower part of chest against table to facilitate exhaling
Artificial airways are inserted to?
maintain air passage for client’s whose airway has or may become obstructed
oropharyngeal airways stimulate…
gag reflex and are used only for clients w altered levels of consciousness
To insert an oropharyngeal airway
- place client in supine or semi fowlers position
- hold lubricated airway by outer flange w distal end pointing UP
- open clients mouth and insert airway along top of mouth
- when distal end reaches soft palate at back of mouth, rotate airway 180 degrees DOWNWARD, slip past uvula to oral pharynx
- if not contradicted place pt in side lying position to allow secretions to drain out of mouth
- oropharynx may be suctioned as needed, by inserting suction along airway
- do not tape airway in place, remove when client begins to cough or gag
Nasopharyngeal airways are tolerated better by
alert clients
Hypoxia
insufficient 02 to meet metabolic demands of tissues and cells
Oxygen devices fall into 2 categories
High flow devices and Low flow devices
High flow devices
discourage en training room air, which dilutes inspired oxygen percentage
- venturi mask
- large volume nebulizer
- blender masks
Low flow devices
- nasal cannula
- various types of face masks
- tracheostomy bag
Saftey guidelines for oxygen
- know pts normal vital signs & pule oximetry values (SP02)
- be aware of environmental conditions
- Document pts smoking history
- know pts most recent hemoglobin value
- oxygen is medication
- provide education
Nasal Cannula flow rate
1-6L?min,
Higher flow rates dry airway mucosa & do not increase inspired oxygen concentration, do not use humidifiers for rates less then 4L/min
Simple oxygen face mask
for short term 02 therapy, fits loosley and delivers 02 concentration form 40% to 60%
Venturi mask
cone shaped high flow device w entrainment ports of various sizes at base of mask entrainment ports adjust to permit regulation of 02 form 24% to 60%, this mask useful because delivers more precise concentration of oxygen to pt
Incentive spirometer helps a pt
deep breathe
Incentive spirometer often used after
abdominal or thoracic surgery to reduce incidence of past operative pulmonary atelectasis
Incentive spirometer provides visual feedback to pts about
depth of their breaths
two types of incentive spirometer
flow oriented and volume oriented devices
flow oriented incentive spirometer
one or more plastic chambers w freely moving colored balls, As pt inhales slowly balls elevated to premarked area, pts goal to keep balls elevated for long as possible to maintain maximal sustained inhilation
volume oriented devices
pt must raise to predetermined volume by inhaling slowly
pts benefiting from incentive spirometery include
using it before surgery, especially for abdominal, cardiac or orthopedic surgery, pts w history of smoking pneumonia or chronic respiratory disease & pts w atelectasis
expected outcomes for incentive spirometry
- pt demonstrates correct use of IS
- pt achieves target volume & number of repetitions per hour
- pt has improved breath sounds
Incentive spirometer implementation:
- position pt in erect position (eg. high fowlers)
- instruct pt to exhale completey through mouth & put lips tightly around mouthpeice
- instruct pt take slow deep breath & maintain constant flow–like pulling through straw –when pt cannot inhale anymore maximal inspiration reached
- have pt hold breath for at least 3 seconds & then exhale normally
- remind pt to perform IS excercises 5-10 times followd by controlled coughing every hour while awake as directed by health care provider
airway size correct
when flange is held parallel to front teeth w ariway against pts cheek end curve reaches angle of jaw
expected outcomes for oral airway
- pts respiratory status improves – resps normal rate, easier removal of secretions, lack of gargling noise in throat w respiration
- pt not able to grind teeth or bite tubes
- pts tounge does not obstruct airway
family members can verbalize understanding of need for
oropharyngeal airways
do not continue inserting oral airway if pt begins to
gag
oral aiways seldom used in treatment of ariway obstruction in
infants and children, airway so narrow causes more harm then benefits
Asepsis
“without infection” implies absence of disease causing microorganisms
aspetic technique or sterile technique is used to
to decrease possibility of transferring microorganisms from one place to another
sterile technique
strictest possible measures to maintain sterility throughout procedure
aseptic technique
(clean technique) clean, absence of almost all but not all microorganisms, efforts made to reduce transfer of microorganisms
Principles and Practices of establishing & maintaining a sterile feild
- All objects used in a sterile feild must be sterile
- sterile objects become unsterile when touched by unsterile objects
- Sterile items that are out of vision or below waist of nurse are considered unsterile
- sterile objects can become unsterile by prolonged exposure to airborne dust containing microorganisms
- fluid flow in one direction of gravity
- moisture that passes through a sterile object draws microorganisms from unsterile surfaces above or below to sterile surface by capillary action
- skin is unsterile and cannot be sterilized
- conscientiousness, alertness and honesty are essential qualities in maintaining surgical asepesis
sterile feild
microorgamism free area
culture and sensitivity test for urine
culture identify if bacteria is present
sensitivity most effective antibiotic for treatment
collecting a clean voided urinal sample
- perform peri-care
- using surgical aspesis, open outer package of specimen kit
- open specimen container, maintaining sterility of inside specimen container & place cap w sterile inside up –do not touch inside of cap or container
Male urine sample
- hold penis w one hand, using circular motion & antiseptic towelette, clean meatus, moving from center to outside 3x w different towelettes, uncircumcised retract fore skin clean and keep retraced for voiding
- pt initiates urine stream stops then tarts again for you to collect 90 -120 ml of urine
Female urine sample
- spread labia minora w fingers of non dominant hand
- w dominant hand clean urethral area w antiseptic swab, move from front to back use fresh swab each time, clean 3x, while continuing to hold labia apart, pt initiates urine stream into toilet/bed pan after stream achieved pass container into stream
Collecting urine from indwelling catheter
- clamp catheter with rubber band for 10-15 min (urine cannot be obtained form drainage bag-unsterile)
- location of port is where catheter attaches to drainage bag
- clean port for 15 seconds w disinfectant swab & allow to dry
- attach needless luer-lok syringe to port
- withdraw 3ml for C&S or 20 ml for routine urinalysis
- transfer form syringe into clean urine container for routine urinalysis or sterile urine container for C&S
- unclamp catheter
- send specimen & completed requisiton to lab within 20 min, refrigerate specimen if delay cannot be avoided
Obtain cultures from pts before
antibiotics started, may interrupt growth of microorganisms, if pt receiving antibiotics notify lab & identify antibiotics pt receiving
Collection of specimen from nose & throat can cause
discomfort and gagging
important to collect throat culture before
mealtime or at least 1 hr after eating/drinking to decrease chance of inducing vomiting
pts clear understanding of specimen collection and technique minimizes
anxiety or discomfort
parenteral medications
administered in manner other than digestive tract
subcutaneous injection
injection into tissues just under dermis of skin
intramuscular injection
injection into body of a muscle
