Q

Pneumonia: definition

A

inflammation of the lung parenchyma by various microorganisms, bacteria, fungi, and viruses: infection is deep in lungs
-infection causes inflammation which attracts WBCs to fill alveoli causing decreased ability for as exchange causing poorly oxygenated blood

Q

pneumonia: diagnosis

A
  • chest xray: determines diagnosis

Q

initial treatment fo pneumonia

A
  • oxygenation assessment
  • start abx after culture: should improve in 24-48 hours
  • initially use broad spectrum abx
  • after C &S results start Iv antibiotics hen PO abx
17
Q

ongoing treatment of pneumonia

A
  • assess vitals and O2
  • comfort, positing,
  • administer meds
  • splint for pleuritic chest pain
  • supplemental oxygen
  • fluids,
  • respiratory therapist: postural drainage/ percussion
  • suction if needed
  • rest and increase activity when fever subsides
  • stop smoking
  • pneumovax on discharge
  • flu vaccine can lead to PNA
18
Q

complications of pneumonia

A
  • Empyema: build up of pus or fluid with demonstrable bacteria in pleural space
  • pleural effusion
  • septic shock
  • respiratory
19
Q

aspiration pneumonia

A
  • food enters trachea instead of esophagus and causes infection
  • inhalation of bacteria in oropharynx and/or content of oropharyngeal/gastric content
20
Q

aspiration pneumonia: those at risk

A
  • impaired LOC
  • depressed cough reflex
  • dysphagia
  • GE reflux
  • vomiting
  • supine positioning
21
Q

prevention aspiration pneumonia

A
  • head of bed elevated with sedated/intubated/NGt
  • NGT- tube feeds off when flat
  • check placement of NGT
  • during emesis: turn on side if sedated or flat if unable to sit up
22
Q

tuberculosis: definition

A
  • highly contagious respiratory infection caused by mycobacterium tuberculosis bacilli
  • airborne droplets
  • can travel to meningitis, kidney, bones, lymph ode
  • initial infection occur 2-10 weeks after exposure
23
Q

Latent tuberculosis

A
  • after exposure: localized infection in lungs that walled off by immune system
  • no symptoms and not contagious
  • can reactivate: when immune system is stressed
  • usually positive in PPD
24
Q

active tuberculosis

A

-exposed person develops acute illness

25
Q

symptoms

A
  • varied to none; insidious
  • early on: may be asymptomatic
  • cough: starts nonproductive and becomes mucoplurulent sputum; may have hemoptysis
  • night sweats
  • loss of appetite
  • unintended weight loss
  • malaise
  • SOB
26
Q

AFB smear

A
  • acid fast smear
  • done while culture is being tested
  • if postive: could be m. tuberulosis or other mycobacteria
27
Q

AFB culture

A

need a sputum sample

-maytakes weeks for culture to grow

28
Q

tuberculosis diagnosis: specimen

A

-3 consecutive sputum specimen, collected 8-24hrs intervals with at least one in the morning
-must have at least 2mL
-

29
Q

tuberculosis diagnosis

A
  • culture
  • afb smear
  • tuberculin skin test
  • chest Xray: show small patchy infiltrations of early lesions in upper lung
  • cavitation and scar tissue
30
Q

tuberculin skin test (Mantoux/PPD)

A
  • only way to identify exposure before it progresses to active disease
  • repeat test after 1-3 weeks after initial test in recommended for older adults: may have decreased response to tuberculin because of viral, bacterial infection and malnutrition
31
Q

positive ppd fining

A

15mm induration for people without risk factors

  • 10mm: resident of long term care families, drug abusers, medically underserved, healthcare workers
  • 5mm: HIV positive, recent contact with active TB
32
Q

management of tuberculosi

A
  • isolation
  • INH or rifampin, monitor liver toxicity
  • multiple drug combination-
  • DOT: directly observed therapy: recommenced for high risk/ unreliable patients: treat them in hospital
33
Q

nursing considerations for TB

A
  • adhere to medication regime
  • take on empty stomach
  • INH avoid: histamine: red wine, aged cheese– flushing, h/a, hypotension, light headedness
  • Rifampn interaction cause them to be ineffective: beta blockers, anticoagulants, birth control pills: check LFT, BUN, creatine
  • prevent TB spread
  • reportable to health department
34
Q

TB nursing priorities

A
  • adequate ventilation/oxygenation
  • prevent spread with PPE
  • support behaviors to maintain health
  • promote effective coping strategies
  • provide information about disease/prognosis and treatment need
35
Q

tramission of TB

A
  • airborn precaution/ isolation with negative pressure room
  • N95
  • discontinue: no evidence of infectiousness: cough decreased, sputum culture show less organism or negative
36
Q

airborne precaustion

A
  • Are used to prevent transmission of microorganisms spread on very small particles that drift on air currents such as droplet nuclei, dust particles. These organisms can remain suspended in the air for long periods of time
  • Pulmonary Tuberculosis (TB)Varicella (Chicken Pox)Measles
