pneumonia/dyspnea Flashcards
what is dyspnea
laboured or difficulty breathing
shortness of breath, feeling your not getting enough air
SUBJECTIVE experience
risk factors for dyspnea?
SMOKING exposure to second hand smoke family history of lung disease genetic make up allergens and environmental pollutants recreational and occupational exposure poor nutrition inadequate exercise substance abuse stress
diagnostic tests for dyspnea?
o2 sat hgb, RBC, WBC, ABGs chest x-ray CT chest throat or sputum cultures possibly bronchoscopy PFTs
nursing interventions for dyspnea
multiple strategies decrease anxiety treat (if possible) underlying pathology oxygen may be helpful patient position pursed lip breathing meds
what is pneumonia?
inflammation of lung parenchyma caused by various microorganisms
-leading cause of death from infection, 5th leading cause of death worldwide
causes of pneumonia?
bacteria mycobacteria chlamydial mycoplasma fungi parasites viruses
community-acquired pneumonia?
develops in community or within 48 hrs of admission -STREPOTOCOCCUS PNEMONIAE (most common) haemophilus influenza pseudomonas aeurignosa legionella
hospital-acquired pneumonia (nosocomial)?
onset of symptoms more than 48 hrs after admission -most lethal of infetions -eneterobcater species e coli h influenzae staphylococcus auerus (MRSA) pseudomonas aeruginosa
why do hospitalized pts develop pneumonia?
- host defences impaired,
- inoculums or organisms reach lower resp tract
- HIGHLY virulent
how to prevent HAP?
frequent oral hygiene isolation of pts with known pneumonia reposition, early ambulation nutritious diet deep breathing and cough clean equipment
pneumonia in the immunocompromised ptient?
immunocompromised due to a variety of factors
-could be caused by CAP o HAP organisms
commonly acquire pneumonia from organisms of low virulence
-pneumocystis pneumonia and other fungal pneuonia
TB (mycobacterium tuberculosis)
aspiration pneumonia?
resulting from entry of endogenous or exogenous substances into lower airway
-most common form of aspiration of bacteria that normally live in upper airway, substances other than bacteria can aspirate and cause pneumonia
diagnostic findings associated with pneumonia?
-history of resp tract infection
-physical exam reveals: fever, chills, rigors, pleuritics chest pain worsened by coughing and deep breathing, may have flushed cheeks and circumoral cyanosis, cyanotic nail beds
-tachypnea (24-45), SOB, acessory muscle use
-some have URTI symptoms (running nose etc)
rash, pharyngitis
-mucoid or mucopurulent sputum may be evident after a few days
diagnostics for pneumonia?
chest x-ray CBC (elevated WBCs, leukcytes) sputum sample for c and s blood cultures (bacteremia common) ABGs oxygen sats
medical management of pneumonia?
-causative agents
-prompt administration of abx
prompt administration of antibiotic is KEY
length of treatment depends on causative agent
hydration
symptoms can be treated with supportive meds
bed rest
oxygen therapy
nursing assessments of pneumonia?
fever, chills, night sweats pleuritic-type pain fatigue tachypnea (use of accessory muscles) coughing, purulent sputum bradycardia assess oldeer pt for unusual behaviour, altered mental status, dehydration, fatigue, HF
nursing assessments after diagnosis?
-head to toe: changes in physical assessment watch for changes in temp, pulse, 02 sats -amount odour and color of secretions -degree of tachypnea and dyspnea -changes on chest x-ray -fatigue -fluid balance -oral intake of fluid -effect of meds -pt understanding of treatment
