Guidelines for Measuring Vital Signs
  • Establish a baseline for future assessments.
  • Be able to understand and interpret values.
  • Appropriately delegate measurement.
  • Communicate findings.
  • Ensure equipment is in working order.
  • Accurately document findings.

3
VITAL SIGNS
  • TEMPERATURE
  • BLOOD PRESSURE
  • PULSE
  • APICAL
  • RADIAL
  • RESPIRATIONS
  • PULSE OXIMETRY
  • PAIN SCALE

4
VITAL SIGNS ARE PART OF THE PHYSICAL ASSESSMENT
  • Delegation of Duties to UAP
  • Unlicensed Assistive Personnel
  • RN is Responsible to Manage Care Based on
    Physical Assessment
  • Administering medications
  • Communicating to other members of the health care
    team
  • Supervising delegated tasks

5
EQUIPMENT
  • RN is responsible for assuring equipment is
    functioning properly
  • Appropriate equipment
  • Must be appropriate to patient age size
  • Thermometer
  • Stethascope Diaphragm (high-pitched sounds)
    bell (low-pitched sounds)
  • BP cuff
  • Pulse oximeter

6
PATIENT HISTORY
  • RN must know patient medical history, including
    medications
  • These facts can affect vital signs
  • RN is responsible for knowing the patients usual
    vital sign range

7
FREQUENCY OF VITAL SIGNS
  • Physicians order the frequency of vital signs
  • Could be ordered by protocol or policy
  • The RN can increase the frequency based on
    his/her assessment
  • VITAL SIGNS can be an early warning sign that
    complications are developing

8
INDICATIONS FOR MEDICATION ADMINISTRATION
  • Many medications are administered when the vital
    signs are within an acceptable range.
  • Accurate VITAL SIGNS are required in order to
    make treatment decisions.

9
COMPREHENSIVE ASSESSMENT FINDINGS
  • Compare VITAL SIGNS to assessment findings and
    laboratory results to accurately interpret the
    patient status.
  • Discuss your findings with peers and charge RN
    before deciding on a plan of action.

10
Temperature
  • Represents the balance of heat produced by
    metabolism, muscular activity, and other factors
    and heat lost through the skin, lungs, and body
    waste
  • A stable temperature pattern promotes proper
    function of cells, tissues, and organs a change
    in this pattern usually signals the onset of
    illness.

11
TEMPERATURE
  • Factors affecting body temp. (36-38C/96.8-100.4F
    )
  • Age
  • Infants 95.9 99.5 F 36.5-37.2C
  • Elderly Average temp is 96.8 F Sensitive to
    temp extremes
  • Exercise
  • Hormone levels
  • Circadian rhythm
  • Stress
  • Environment

12
TEMPERATURE ALTERATIONS
  • Afebrile
  • Fever of unknown origin (FUO)
  • Malignant hyperthermia hereditary, occurs during
    anesthesia
  • Heatstroke medical emergency
  • Heat exhaustion
  • Hypothermia
  • Frostbite

13
Measurement of Temperature
  • Electronic digital
  • Chemical-dot
  • Tympanic
  • Oral 97-99.5F 36.1-37.5C
  • Rectal (most accurate) is usually 1F or 0.6C
    higher
  • Axillary, least accurate 1-2F or0.6-1.1C lower
  • Tympanic 0.5-1F higher

14
TEMPERATURE Contd.
  • Sites
  • Core temp is measured in pulmonary artery,
    temporal artery, esophagus, and urinary bladder
  • Mouth, rectum, tympanic membrane, and axilla
  • Variety of types available electronic and
    disposable
  • Antipyretics drugs that reduce fever

15
  • Using an oral electronic thermometer, the nurse
    checks the early morning temperature of a client.
    The client's temperature is 36.1 C (97 F). The
    client's remaining vital signs are in the
    normally acceptable range. What should the nurse
    do next?
  • A) Check the client's temperature history. B)
    Document the results temperature is normal. C)
    Recheck the temperature every 15 minutes until
    it is normal. D) Get another thermometer the
    temperature is obviously an error.

16
Equipment
  • Electronic thermometer, chemical-dot thermometer
    or tympanic thermometer
  • Facial tissue
  • Disposable thermometer sheath or probe cover
  • Alcohol pad
  • If you are using an electronic thermometer, make
    sure its been recharged

How to
  • You can take an oral, rectal, or axillary temp
    with various electronic digital thermometers or a
    chemical-dot device
  • Use oral route for most adults who are awake,
    alert, oriented and cooperative.
  • For infants, young children, and confused or
    unconscious pts, you may need to take the temp
    rectally.
  • The tympanic route may be used on almost all pts.

22
Taking a Temp
  • Hand hygiene
  • Confirm pts identity with two pt identifiers
  • Explain procedure to pt
  • If pt has had hot or cold liquids, chewed gum or
    smoked, wait 15 minutes before taking an oral temp

23
Taking a Tympanic Temp
  • Make sure the lens under the probe is clean and
    shiny. Attach a disposable probe cover.
  • Examine the pts ear. It should be free from
    cerumen to obtain and accurate reading. If the
    pt has any visible lesion or drainage STOP
  • Stabilize the pts head gently pull the ear up
    and back.
  • Insert the tenmometer until the ear canal is
    sealed. Insert like an otoscope.
  • Press the button to activate. Hold 1 second.

24
Taking an Oral Temp
  • Position the thermometer under the pts tongue,
    as far back as possible on either side of the
    frenulum linguae. (promotes contact with
    superficial blood vessels and contributes to
    accurate reading)
  • Instruct pt to close lips but avoid biting down
    with teeth.
  • Leave a chemical-dot in place for 45 sec. Read
    the last dot that has changed color.
  • Wait until maximum temp is displayed on
    electronic thermometer.

25
Taking an Axillary Temp
  • Position the pt with axilla exposed.
  • Gently pat the axilla dry with a facial tissue
    because moisture conducts heat.
  • Avoid harsh rubbing, which generates heat
  • Ask the pt to reach across chest and grasp the
    opposite shoulder, lifting elbow.
  • Position the thermometer in the center of the
    axilla.
  • Tell pt to keep grasping shoulder and lower elbow
    against chest. This promotes skin contact with
    the thermometer probe

26
Remember
  • Axillary temps take longer to register than oral
    or rectal temps because the thermometer isnt
    enclosed in a body cavity.
  • Dispose of the probe cover.
  • Perform hand hygiene
  • Clean or disinfect the electronic model after use
    to prevent cross-contamination.
  • Perform hand hygiene.
  • Document the procedure.

27
Special Considerations
  • Make sure the probe cover doesnt have any
    wrinkles, they interfer with the reading.
  • Oral measurement is contraindicated in pts who
    are unconscious, disoriented, or seizure-prone
    in young children and infants and in pts who
    must breathe through their mouths.
  • Use the same thermometer for repeats to avoid
    spurious variations
  • Dont avoid oral temps in pts receiving nasal
    oxygen (Oxygen administration raises oral temp
    only 0.3F or 0.17C
  • Make sure you document where the temp as taken.

28
Pulse
  • Blood is pumped into an already-full aorta during
    ventricular contraction creates a fluid wave that
    travels from the heart to the peripheral
    arteries.
  • This recurring wave is called a pulse and can be
    palpated at locations on the body where an artery
    crosses over bone on firm tissue.
  • In adults and children older than age 3 and in
    adults with a suspected cardiac disorder that
    affects the pts heart rate and rhythm, the
    radial artery is the most common palpation site.
  • In infants and children younger than age 3, a
    stethoscope is used to listen to the heart

29
(No Transcript)
30
Apical-Radial Pulse
  • Taken simultaneously counting apical and radial
    beats
  • First by auscultation at the apex of the heart
  • Second by palpation at the radial artery
  • Some heartbeats detected at the apex cannot be
    detected at peripheral sites
  • When this occurs, the apical pulse rate is higher
    than the radial the difference is the pulse
    deficit.

31
What to Assess
  • Determine the rate (number of beats per minute)
  • Rhythm (pattern or regularity of the beats)
  • Volume (amount of blood pumped with each beat.
  • If the pulse is faint or weak, use a Doppler
    ultrasonic blood flow detector if available.

32
PULSE
  • Sites
  • Temporal, Carotid, Apical, Brachial, Radial,
    Femoral, Popliteal, Posterior Tibial, Dorsalis
    Pedis
  • Increases in HR
  • Short-term exercise, fever, heat, pain, anxiety,
    drugs, loss of blood, standing or sitting, poor
    oxygenation
  • Decreases in HR
  • Long-term exercise, hypothermia, relaxation,
    drugs, lying down

33
Taking a Radial Pulse
  • You will need a watch with a second hand, a
    stethoscope alcohol pad.
  • If not using your own stethoscope disinfect
    earpieces
  • Confirm pt identity
  • Hand hygiene
  • Tell pt you intend to take his pulse
  • Make sure pt is comfortable relaxed because an
    awkward, uncomfortable position may affect heart
    rate.
  • Place pt is a sitting or supine position, with
    arm at the side or across the chest.

34
Radial Pulse Taking
  • After locating the pulse, count the beats for 60
    seconds, or 30 sec and multiply by 2.
  • Counting for a full minute provides a more
    accurate picture of irregularities.
  • If you detect an irregularity, repeat the count,
    and note whether it occurs in a pattern or
    randomly. If in doubt, take an apical pulse.
  • Document
  • Gently press your index, middle and ring fingers
    on the radial artery, inside the pts wrist. You
    should feel a pulse with only moderate pressure
    excessive pressure may obstruct blood flow distal
    to the pulse site.
  • Dont use your thumb. Why?

35
Taking an Apical Pulse
  • Help the pt to a supine position and drape
  • Warm the diaphragm or bell of the stethoscope in
    your hand. A cold stethoscope may startle the pt
    and momentarily increase heart rate.
  • Place diaphragm over apex of heart.
  • Where? 5th intercostal space, left of the
    midclavicular line
  • Count for 60 seconds, note rate, rhythm, volume
    and intensity.
  • Make pt comfortable
  • Clean stethoscope
  • Document

36
PULSE Contd.
  • Volume of blood pumped by the heart during 1
    minute is the cardiac output
  • When mechanical, neural or chemical factors are
    unable to alter stroke volume, a change in heart
    rate will result in change in cardiac output,
    which affects blood pressure
  • HR ?, less time for heart to fill, BP ?
  • HR ?, filling time is increased, BP ?
  • An abnormally slow, rapid, or irregular pulse
    alters cardiac output

37
  • The nurse decides to take an apical pulse instead
    of a radial pulse. Which of the following client
    conditions influenced the nurse's decision?
  • A) The client is in shock. B) The client has
    an arrhythmia. C) The client underwent surgery
    18 hours earlier. D) The client showed a
    response to orthostatic changes.

38
Taking an Apical-Radial Pulse
  • Two nurses work together to obtain the
    apical-radial pulse
  • One palpates the radial pulse while the other
    auscultates the apical pulse with a stethoscope.
  • Both must use the same watch when counting beats.

39
Pulse Patterns
  • Normal 60-100 beats/minute in neonates
    120-140 beats/minute
  • Varies with such factors as age, physical
    activity and gender
  • Men usually have lower pulse rates than women

40
Tachycardia
  • More than 100 beats/minute
  • Accompanies stimulation of the sympathetic
    nervous system by emotional stress, such as
    anger, fear, or anxiety, or by the use of certain
    drugs such as caffeine.
  • May result from exercise and from certain health
    conditions, such as heart failure, anemia, and
    fever (which increase oxygen requirements and
    therefore increase pulse rates)

41
Bradycardia
  • Less than 60 beats/minute
  • Accompanies stimulation of the parasympathetic
    nervous system by drug use, especially digoxin,
    and such conditions as cerebral hemorrhage and
    heart block.
  • May also be present in fit athletes.

42
Irregular Pulse
  • Uneven time intervals between beats (for example,
    periods of regular rhythm interrupted by pauses
    or premature beats)
  • May indicate cardiac irritability, hypoxia,
    digoxin toxicity, potassium imbalance, or
    sometimes more serious arrhythmias if premature
    beats occur frequently
  • Occasional premature beats are normal

43
Special Considerations
  • When peripheral pulse is irregular, take an
    apical
  • If pulse is weak or faint get a Doppler
  • If taking an apical-radial alone, hold
    stethoscope in place with the hand that holds th
    watch while palpating the radial with the other
    hand
  • Document pulse rate, rhythm, and volume as well
    as time of measurement. Full/Boundingincreased
    volume
  • Weak/Threadydecreased volume
  • A/R 80/76

44
RESPIRATIONS
  • Ventilation the movement of gases in and out of
    lungs
  • Diffusion the movement of oxygen and CO2
    between the alveoli and RBCs
  • Perfusion the distribution of RBCs to and from
    the pulmonary capillaries

45
Respiration
  • Controlled by the respiratory center in the
    lateral medulla oblongata
  • Exchange of O2 and CO2 between the atmosphere and
    body cells
  • Accomplished by the diaphragm and chest muscles
  • Four measures
  • Rate
  • Rhythm
  • Depth
  • Sound
  • Reflect bodys metabolic state, diaphragm and
    chest muscle condition and airway patency

46
Implementation
  • Hand hygiene
  • After taking pulse keep your fingertips over the
    radial artery and dont tell the pt you are
    counting respirations
  • Observe chest rise and fall
  • Count for 30 seconds x2 or 1 full minute.
  • Be alert for and record breath sounds such as
    stridor, stertor, wheezing and an expiratory
    grunt.

47
Refresher
  • Stridor inspiratory crowing sound that occurs
    with upper airway obstruction in laryngitis,
    croup, or the presence of a foreign body
  • Wheezing caused by partial airway obstruction in
    the smaller bronchi and bronchioles. This
    high-pitched musical sound is common in pts with
    emphysema asthma
  • Stertor snoring sound resulting from secretions
    in the trachea and large bronchi
  • Listen for it in pts with neurologic disorders
    and those who are comatose

48
Elder Alert
  • In older pts, an expiratory grunt may result from
    partial airway obstruction or neuromuscular reflex

49
Assessment
  • Observe chest movements for depths of
    respirations. Shallow vs Deep
  • Listen with stethoscope to determine rhythm and
    sound of respirations. Crackles/rhonchi or lack
    of sound
  • Observe the use of accessory muscles scalene,
    sternocleidomstoid, trapezius, and latissimus
    dorsi. Reflects weakness of diaphragm and
    intercostals

50
Patterns
  • Apnea periodic absence (mechanical/brain)
  • Apneustic prolonged, gasping inspiration,
    followed by extremely short, inefficient
    expiration (lesions of respiratory center)
  • Bradypnea slow, regular respirations (sleep,
    opiates, ETOH, tumors, metabolic disorders
  • Cheyne-Stokes Fast, deep puncuated by periods of
    apnea lasting 20 to 60 seconds (inc ICP, severe
    heart failure, meningitis, drugOD, cerebral
    anoxia.

51
Patterns
  • Eupnea normal rate rhythm
  • Kussmauls Fast (over 20 breaths/minute), deep
    (resembling sighs), labored without pause (renal
    failure or metabolic acidosis, DKA
  • Tachypnea rapid respirations. Rate rises with
    body temperature about 4 breaths/minute for
    every degree F above normal. (PNA, respiratory
    insufficiency, lesions of respiratory center,
    salicylate poisoning)

52
Special considerations
  • Rate lt 8 or gt 40 are abnormal. Report ASAP
  • Observe for dyspnea anxious facial expression,
    nasal flaring, heaving chest wall, cyanosis.
  • To detect cyanosis check nail beds, lips, under
    the tongue, buccal mucosa, conjunctiva.
  • Consider personal and family hx. Smoker? ? Pack
    years?

53
Factors Influencing Character of Respirations
  • Exercise
  • Acute Pain
  • Anxiety
  • Smoking
  • Body Position
  • Medications
  • Neurological injury
  • Hemoglobin function

54
Pulse Oximetry
  • Noninvasive estimation of arterial oxyhemoglobin
    saturation
  • Emits 2 wavelengths of light, one red, one
    infared. Well oxygenated blood absorbs light
    differently from deoxygenated blood
  • Oximeter determines amount of light absorbed by
    the vascular bed and calculates saturation SpO2

55
Pulse Ox
  • Saturation of 90 is equivalent to an arterial
    blood gas value of 60 torr
  • Early detector of impending hypoxemia
  • Rapid response time between changes in pt status
    and reading on pulse ox
  • Accurate within the range of 65 - 95 saturation
    with only a 1-2 error
  • Able to assess pt draped in darkened room

56
Uses
  • ICU
  • Pre/Peri operative areas where sedation decreases
    LOC, might mask hypoxemia
  • Assessed routinely with VS
  • Exercise testing

57
Prepare site
  • Remove fingernail polish, cleanse skin
  • Area of probe placement should be checked for
    proper circulation with good cap refill.
  • Pts with poor cap refill secondary to PVD will be
    better monitored utilizing earlobes, nose or
    forehead.

58
Probes
  • Probes can be permanent or disposable
  • Recheck probe location for cap refill after probe
    placement and intermittently during pt
    monitoring.
  • Not on same arm as BP cuff
  • No information on pts ventillatory status
  • If O2 sat is below 65, the monitor will
    overestimate the saturationproviding inaccurate
    measurement

59
Locations for Pulse Ox
  • Repetitive studies has shown probes placed on
    earlobes are more accurate and have faster
    response times.
  • Earlobes, nose, forehead, toe
  • If Hgb variants are present/ carboxyhgb values
    are less. Other factors that effect oximetry
    motion, anemia, bright flourescent lights,
    artificial fingernails, dark skin color

60
Situations in which Pulse oximetry is limited
  • Severe hypothermia
  • Pt is receiving intravascular dyes, impact
    short-lived, but need other methods to ensure
    oxygenation
  • Significant hypotension
  • Vasoconstrictive drug use
  • Arterial compression/pulsating venous blood
  • Anemia
  • Carbon monoxide posioning
  • Muscular contraction

61
PULSE OXIMETER
  • Indirect measurement of oxygen saturation
  • Photodetector detects the amount of oxygen bound
    to hemoglobin molecules and oximeter calculates
    the pulse saturation
  • Only reliable when SaO2 is over 70
  • Certain conditions may give an inaccurate reading

62
  • A client is being monitored with pulse oximetry.
    On review of the following factors, the nurse
    suspects that the values will be influenced by
    which of the following?
  • A) The placement of the sensor on the
    extremityB) A diagnosis of peripheral vascular
    diseaseC) A reduced amount of artificial light
    in the roomD) The increased ambient temperature
    of the clients room

63
BLOOD PRESSURE
  • Force exerted on the walls of an artery by the
    pulsing blood under pressure from the heart
  • Systolic maximum pressure when ejection occurs
  • Diastolic minimum pressure of blood remaining
    in the arteries after ventricles relax

64
BP Depends ON
  • Force of ventricular contractions
  • Arterial wall elasticity
  • Peripheral vascular resistance
  • Reflects integrity of the heart, arteries,
    arterioles
  • Diastolic or minimal pressure occurs during left
    ventricular relaxation and directly indicates
    blood vessel resistance

65
BLOOD PRESSURE Contd.
  • Physiology of arterial blood pressure
  • Cardiac Output, Peripheral resistance, Blood
    volume, Viscosity, Elasticity
  • Factors influencing BP
  • Age, Stress, Ethnicity, Gender, Daily Variation,
    Meds, Activity, Weight, Smoking
  • Hypertension
  • Hypotension
  • Orthostatic or postural hypotension

66
Frequent BP Measurement
  • After serious injury, surgery, anesthesia and
    during illness or condition that threatens CV
    stability
  • Unstable pts
  • Pts receiving blood transfusion
  • Pts receiving oral or IV meds to stabilize BP

67
Classification of BP
Category SBP mmHg DBP mmHg
Normal lt120 And lt80
Prehypertension 120-139 Or 80-89
Hypertension, stage 1 140-159 Or 90-99
Hypertension, stage 2 160 or higher Or 100 or higher
68
Prepare Equipment
  • Choose appropriate size cuff bladder should
    encircle at least 80 of the upper arm
  • Excessively narrow cuff may cause a falsely high
    reading an excessively wide one, a falsely low
    reading.
  • Palpate brachial artery. Position cuff 1 above
    site of pulsation, center above artery. Wrap
    snug.
  • Confirm pt identity.

69
Pre-Procedure
  • Have pt rest for at least 5 minutes.
  • No smoking or caffeine
  • Explain to pt
  • Supine or sitting OK. No crossed legs
  • Extend arm at level of heart. If below could get
    false-high reading
  • Forearm and thigh alternative option
  • Inflate cuff til radial pulse disappears, add
    30mmHg. Deflate cuff. Place stethoscope over
    brachial artery

70
Procedure
  • Pump cuff to determined level.
  • Carefully open valve and slowly deflate, no
    faster than 2-3mmHg/second.
  • Ausculatate sound over artery.
  • First beat SBP (first of 5 Korotkoff sounds,
    second is swish, third crisp tapping, fourth a
    soft muffle and fifth the last sound heard)
  • Note pressure where sound disappearsDBP

71
Special Considerations
  • If you cant auscultate BP you can estimate SBP
    by palpation. Palpate brachial or radial, inflate
    cuff til you no longer detect the pulse
  • If pt is crying or anxious defer
  • Occasionally BP is measured in both arms or with
    pt in two different postions
  • Measure BP of pts taking antihypertensives in
    sitting position.

72
Complications
  • Dont take BP in arm of the affected side of a
    mastectomy, may decrease already compromised
    lymphatic circulation, worsen edema, damage arm.
  • Dont take BP in same arm of AV fistula or
    hemodialysis shunt blood flow through vascular
    device may be compromised.

73
  • The nurse is assessing a clients blood pressure
    during a routine visit. When asked, the client
    volunteers that when he took his pressure at home
    yesterday it was 126/72 mmHg. The nurse
    determines that the clients pressure today is
    134/70 mmHg. The nurse recognizes that the most
    likely cause of the elevation is due to which of
    the following?
  • A) The difference between the monitoring
    equipment being used
  • B) The clients inability to hear the first
    Korotkoff sound
  • C) The client may be experiencing mild anxiety
    regarding the check-up
  • D) The client is not inflating the cuff
    sufficiently to detect the systolic pressure

74
Critical Thinking Exercise
  • Mr. Coburn, a 56-year-old schoolteacher who was
    seen earlier in the week for hyperthermia,
    arrives at the walk-in clinic complaining of
    feeling dizzy and nauseated. You immediately
    note that her appears to be having some
    difficulty catching his breath during coughing
    spells.
  • List in priority order the vital signs to be
    measured for Mr. Colburn.

75
Priority Order
  • 1. SpO2
  • 2. BP
  • 3. heart rate
  • 4. respiratory rate
  • 5. temperature
  • Which of the vital signs do you delegate to the
    nursing assistant?

76
Delegation
  • Temperature. The pt has signs and symptoms of
    unstable hemodynamics and the nurse should obtain
    other vital signs.
  • The electronic blood pressure machine alarm is
    sounding. You note that it is flashing 72
    systolic with no diastolic reading. What
    actions do you take?

77
Nursing Response
  • Check pt for LOC and palpate for pulse. Check to
    make sure that electronic BP machine is attached
    to pt, and all connections are intact. Repeat BP
    measurement using electronic machine.
  • Mr. Colburns BP according to the machine is
    82/38 mmHg. His radial pulse is 1, slightly
    irregular, and 112 BPM What actions do you take?

78
Nursing Response
  • Obtain BP manually with sphygmomanometer. Obtain
    remaining vital signs including SpO2, RR.
    Administer oxygen if ordered or on protocol.
    Notify nurse in charge or health care provider.
  • You have difficulty auscultating Mr. Coburns
    blood pressure in his left upper arm. List three
    actions that you take?

79
Possible Nursing Actions
  • Take BP in right upper arm
  • Obtain Doppler ultrasound to obtain BP
  • Ask a colleague to measure BP

  • Normal body flora
  • Cilia in lungs
  • Intact skin
  • pH of body fluids
  • Acidic gastric secretions
  • Alkaline vaginal secretions

86
Types of Infections
  • Heath Care-Associated Infections (HAIs formerly
    called nosocomial) result from delivery of
    health services in a health care facility
  • Iatrogenic a type of HAI from a diagnostic or
    therapeutic procedure
  • Exogenous an infection that is present outside
    the client, i.e. a post-op infection
  • Endogenous an infection that occurs when part of
    the clients flora becomes altered or overgrowth
    results, i.e. C. Diff, vaginal yeast infection

87
  • Which of the following is an example of a nursing
    intervention that is implemented to reduce a
    reservoir of infection for a client?
  • A) Covering the mouth and nose when sneezingB)
    Wearing disposable glovesC) Isolating clients
    articlesD) Changing soiled dressings

88
VIGNETTE
  • An older adult, hospitalized with a GI disorder
    is on bedrest and requires assistance for
    uncontrolled diarrhea stools.
  • Following one episode of cleaning the patient and
    changing the bed linens, the nurse went to a
    second patient to provide tracheostomy care.
  • The nurses hands were not washed before
    assisting the second patient

89
VIGNETTE ANALYSIS
  • Infectious agent ? Escherichia Coli
  • Reservoir ? Large Intestines
  • Portal of Exit ? Feces
  • Mode of Transmission ? Nurses Hands
  • Portal of Entry ? Tracheostomy
  • Susceptible Host ? Older Adult with Trach

90
NURSING PROCESS
  • Assessment
  • Patient
  • Client Susceptibility
  • Status of defense mechanisms (smoker?)
  • Age very young and very old
  • Nutritional status decreased protein intake
    reduces the bodys defenses against infection and
    impairs wound healing
  • Stress lowers immunity
  • Disease process HIV, Leukemia, Lymphoma
  • Laboratory Data
  • Client needs related to disease status

91
NURSING PROCESS
  • Nursing Diagnosis
  • Risk for infection R/T compromised defense
    mechanism as evidenced by (AEB) presence of
    tracheostomy

92
NURSING PROCESS
  • Planning
  • Goal
  • Patient will remain free from infection during
    hospital stay
  • Interventions
  • Nurse will monitor temperature every 4 hours
    (Expectation Patient will remain afebrile)
  • Nurse will monitor for signs/symptoms of
    infection every shift (Expectation Patient will
    have no s/s of infection)
  • Nurse will maintain standard precautions for all
    patient contact

93
NURSING PROCESS
  • Evaluation
  • Did patient remain infection free?
  • YES Good job!
  • NO ? - Reassess patient and environment to
    determine where the chain of infection was broken

Break The Chain!
  • Implement ASEPSIS absence of disease-producing
    microorganisms refers to practices/procedures
    that assist in reducing the risk of infection
  • 2 Types
  • Medical (clean technique)
  • Surgical (sterile technique)

96
MEDICAL ASEPSIS
  • A clean technique that limits the number of
    pathogens that could cause infections
  • Aseptic technique practices/procedures that
    assist in reducing the risk for infection
  • 3 components to the technique
  • Hand washing,
  • Barriers of PPE (gloves, gowns, mask, protective
    eyewear)
  • Routine environmental cleaning
  • Contaminated area one suspected of containing
    pathogens eg. used bedpan, wet gauze, soiled
    linen, laboratory specimens, etc

97
Disinfection/Sterilization
  • Disinfection the process that eliminates many
    or all microorganisms, with the exception of
    bacterial spores, from inanimate objects
  • Disinfection of surfaces
  • High-level disinfection
  • Alcohols, chlorines, glutaraldehydes, hydrogen
    peroxide
  • Sterilization complete elimination or
    destruction of all microorganism, including
    spores
  • Steam under pressure, ethylene oxide gas (ETO)

98
CDC GUIDELINES
  • Standard Precautions apply to
  • Blood
  • All body fluids and secretions (feces, urine,
    mucus, wound drainage) except sweat
  • Non-intact skin
  • Mucous membranes
  • Respiratory secretions

99
STANDARD PRECAUTIONSTIER 1

108
WHERE ARE WE IN THE CHAIN OF INFECTION?
  • Portal of Exit
  • Susceptible Host
  • Reservoir
  • USE CRITICAL THINKING!!

109
Surgical Asepsis
  • Sterile technique that prevents contamination of
    an open wound, serves to isolate the operative
    area from the unsterile environment, and
    maintains sterile field for surgery
  • Includes procedures used to eliminate all
    microorganisms, including pathogens and spores
    from an object or area
  • Used in the following situations
  • Procedures requiring perforation of the skin
  • When the skins integrity is broken as a result
    of trauma, surgery or burns
  • During procedures that involve insertion of
    catheters or surgical instruments into sterile
    body cavities

110
Principles of Surgical Asepsis
  • A sterile object remains sterile only when
    touched by another sterile object
  • Only sterile objects may be placed on a sterile
    field
  • A sterile object or field out of the range of
    vision or an object held below a persons waist
    is contaminated
  • A sterile object or field becomes contaminated by
    prolonged exposure to air
  • When a sterile surface comes in contact with a
    wet, contaminated surface, the sterile object or
    field becomes contaminated by capillary action
  • Fluid flows in the direction of gravity so a
    sterile object becomes contaminated if gravity
    causes a contaminated liquid to flow over the
    objects surface
  • The edges of a sterile field or container are
    considered to be contaminated a 1 inch border
    around the drape is considered contaminated

111
  • For which procedure would the nurse use aseptic
    technique and which would require the nurse to
    use sterile technique?
  • A) Aseptic technique for urinary catheterization
    in the hospital and sterile technique for
    cleaning surgical wound
  • B) Aseptic technique for changing the patients
    linen and sterile technique for assisting in
    surgery
  • C) Aseptic technique for food preparation and
    sterile technique for starting an IV line
  • D) Aseptic technique for a spinal tap and
    sterile technique for placing a central line

112
LAB Practice Isolation Precautions
  • Demonstrate donning Isolation Gown, Mask, Gloves,
    Eyewear
  • Demonstrate removing Isolation Gown, Mask,
    Gloves, Eyewear
  • Demonstrate proper disposal of PPE before leaving
    Isolation Room
  • When performing care/treatments use hospital
    provided stethoscope and leave in the room

113
Lab Practice Contd.
  • Practice pretending you are entering patient room
    (use curtains) and give Complete Bed Bath and do
    Bed Linen Change wearing PPE (gown, mask, gloves)
  • Remember to dispose of PPE INSIDE the patients
    room before you leave
  • Practice bringing in all the supplies you need so
    you can stay in the room not have to leave
    (de-gown etc) and come back in (re-gown etc)

114
LAB Practice Sterile Procedures
  • Opening sterile packages Flap fartherest away
    from nurse first, then sides, then flap closest
    to nurse
  • Preparing a sterile field
  • Pouring sterile solutions label to palm, lip
    it
  • Donning sterile gown and gloves

115
QUESTIONS?
116
Critical Thinking Exercise
  • Mrs. Jaycock had an indwelling urethral catheter
    for 1 week. The catheter has now been out for 24
    hours. She complains of frequency and pain on
    urination. Mrs. Jaycock suggests reinsertion of
    the catheter because of the need to get up
    frequently. What can frequency or pain on
    urination be an indication of?

117
Answer
  • UTI
  • Should the catheter be reinserted?
  • Why or why not?

118
Answer
  • No reinserting the catheter may aggravate the
    infection and promote the spread of the infection
    to the bloodstream.
  • Describe at least one appropriate assessment
    measure and one independent nursing action or
    intervention for Mrs. Jaycock

119
Nursing Response
  • Increase her fluid intake if not clnically
    contraindicated
  • Check her urinalysis

120
Situation
  • You are caring for Mr. Huang, who has a large
    open, and draining abdominal wound. You notice
    another health care worker changing Mr. Huangs
    dressing without wearing gloves or using sterile
    technique. When you question the health care
    worker regarding his or her practice, this person
    says, Dont worry, the wound is already
    infected, and the antibiotics and drainng will
    take care of any contaminants. How would you
    respond to this comment?

121
Response
  • It is important to not only protect Mr. Huang
    from additional infection, but also to protect
    ourselves from becoming contaminated.
  • What would your next steps be in following up on
    this incident?

122
Situation
  • Mrs. Niles is 83 years of age and lives alone.
    She has difficulty walking and relies on a church
    volunteer group to deliver lunches during the
    week. Her fixed income limits her ability to buy
    food. Last week, Mrs. Niles 79-year-old sister
    died. The two sisters had been very close. As a
    home care nurse, explain the factors that might
    increase Mrs. Niles risk for infection.

123
Response
  • Age
  • Potential for poor nutrition
  • Potential for depression

124
Situation
  • Mr. Vargas is admitted to the facility with a
    history of recent weight loss, a cough that has
    persisted for 2 months, and hemoptysis. His
    chest x-ray film shows a cavity lesion in one
    lung, and his physician suspects tuberculosis.
    What type of isolation precautions would you use
    for Mr. Vargas? What protection would you use to
    provide care? What education would you provide
    to the family?

125
Response
  • Airborne precautions
  • Wear an N95 mask
  • Keep the door closed
  • Educate the pt and family on transmission of TB
    and reason for isolation.
