Respiratory Flashcards
How long are newborns obligatory nose breathers?
Until at least 4 weeks of age
- Newborns only breath through their mouth when they are crying
Anatomical Differences of Respiratory Structures in Children
- Infants are nose breathers with very small nasal passages
- More space is taken up by the tongue
- Enlarged tonsils and adenoids
- Smaller airway
- Narrow larynx (and higher location)
- Airway has less functional supporting muscles
- Smaller number of alveoli
For a focused respiratory assessment, what should be included in the health history?
- Recurrent respiratory issues
- Chronic respiratory disorders
- Fever
- Cough
- Sore throat
- Congestion
- Second hand smoke
- Prematurity
- Daycare/school
Respiratory Focused Assessment (Physical Exam)
- Color
- Nose and oral cavity
- Cough and airway noise
- Respiratory effort
- Retractions
- Anxiety and restlessness
- Clubbing
- Hydration status
- Breath sounds
Wheezing Lung Sounds
High pitched sound (expiration)
What causes wheezing?
Secretions which can be coughed up or cleared, or obstruction of the bronchioles (bronchiolitis, asthma, chronic lung disease, cystic fibrosis) that does not clear with coughing
Rales
AKA crackles
What causes rales?
Caused by the alveoli becoming fluid filled (pneumonia)
Stridor
Heard on inspiration
What causes stridor?
Caused by upper airway obstruction
What is Croup?
A viral infection that causes inflammation, edema, and mucus to obstruct the airway. Narrowing of the trachea occurs.
S/Sx of Croup
- Inspiratory stridor
- “barking” cough
- Symptoms are more severe at night
How long does croup usually last?
3-5 days
Croup Treatment
- Rest
- Corticosteroids
- Racemic epinephrine treatment
- Humidified air
- Increased fluids
What should we teach the parent about croup?
- Its viral so antibiotics are ineffective
- The importance of hygiene
- The s/sx of croup getting worse
What are the s/sx that croup is getting worse?
- Tachypnea
- Lethargy
- Paleness, cyanosis
- Retractions
- Nasal flaring
- Irritability
Home Care of Croup
- Keep the child quiet and discourage crying
- Allow the child to sit up (in your arms)
- Encourage rest and fluid intake
- If stridor occurs, take the child into a steamy bathroom for 10 minutes
- Administer medication (corticosteroid) as directed
What is Bronchiolitis (RSV)?
Highly contagious, acute inflammatory process of the bronchioles and small bronchi. Invades the nasopharynx, replicates, and spreads to the lower airway causing small airway obstruction and necrosis(from mucus and exudate). Almost always caused by the RSV virus.
How do you diagnose RSV?
Mucus swab
S/Sx of RSV
- Fever
- Wheezing
- Cough
- Mucus congestion
- Frequency and severity of the viral infection decreases with age
Nursing Management of RSV
- Management is largely supportive
- Contact and droplet isolation
- Supplemental oxygen
- Suctioning
- Hydration
- Antipyretics
- Bronchodilators
- Sleep with HOB elevated
What should we teach the parents about RSV?
- Very dangerous for infants
- No sick people around infants
- Hand hygiene
- It’s viral, so antibiotics are ineffective
What is pneumonia?
Inflammation of the lung parenchyma. Can be viral, bacterial, or fungal.
What is aspiration pneumonia?
Aspiration of a foreign body
S/Sx of pneumonia
- Fever
- Wheezing
- Rales
- Cough
- Chest pain
- Retractions
Nursing Management of Pneumonia
- Rest
- Analgesics
- Antipyretics
- Adequate hydration
- Supplemental oxygen
- Antibiotic (for bacterial pneumonia)
- Close observation
Pneumonia Recovery
For 1-2 weeks the child might continue to tire easily and the infant might continue to need small, frequent feedings. Cough may also persist after the acute recovery period but should lessen over time.
What is foreign body aspiration?
When any solid or liquid substance is inhaled into the respiratory tract. Can become lodged in the upper or lower airway, causing varying degree of respiratory difficulty.
Treatment of foreign body aspiration
Removed via bronchoscopy and treated with antibiotics if infection is present
Complications of foreign body aspiration
- Pneumonia
- Abscess formation
- Hypoxia
- Respiratory failure
- Death
What is the most important intervention for foreign body aspiration?
Prevention
- Avoid toys with small parts, balloons, coins, peanuts
- Cut grapes, hot dogs, and carrots into small pieces
Lungs sounds that point to foreign body aspiration
The infant or young child might present with a history of sudden onset of cough, wheeze, or stridor. Stridor suggests that the foreign body is lodged in the upper airway. When the item has traveled down one of the bronchi, then wheezing, rhonchi, and decreased aeration can be heard on the affected side
What is asthma?
Chronic inflammatory disorder characterized by airway hyperresponsiveness, airway edema, mucus production, and constriction of the airway. Occurrence ranges from long periods of control or have symptoms daily.
S/Sx of asthma
- Persistent cough (particularly at night)
- Difficulty breathing
- Chest tightness
- Wheezing
- Restlessness
- Barrel chest in severe cases
- Mild retractions can be present
Management of asthma goal
Avoid asthma triggers (allergy testing) and reduce and control inflammatory episodes
What is the stepwise approach?
Used for prescribing medication to asthma patients
Increasing medications as the child’s condition worsens, then backing off as the condition improves. Asthma requires periodic assessment of control and periodic education.
Laboratory Tests for Asthma
- Allergy test
- Pulmonary function tests (PFTs)
- Peak expiratory flow rate (PEFR)
Pulmonary Function Tests for Asthma
Can be very useful in determining the degree of disease but are not useful during an acute attack.
Peak Expiratory Flow Rate during an asthma attack
Is decreased during an exacerbation (asthma attack)
What is cystic fibrosis?
Autosomal recessive disorder
Dysfunction of the exocrine glands resulting in thickened, tenacious secretions (sweat glands, GI tract, pancreas, respiratory tract)
S/Sx of cystic fibrosis
- Salty skin
- Cough
- Barrel chest
- Clubbing of nail beds
- Small appearance for age
- Fine or coarse crackles
- Wheezing
- Diminished breath sounds
Sweat Chloride Test (cystic fibrosis)
Considered suspicious if the level of chloride in collected sweat is above 50 mEq/L and diagnostic if the level is above 60 mEq/L
Pulmonary Function Tests (cystic fibrosis)
Might reveal a decrease in forced vital capacity and forced expiratory volume, with increases in residual volume.
Cystic Fibrosis Interventions
- When in hospital, droplet and contact precautions
- Daily chest physiotherapy
- Vest airway clearance
- Physical exercise (when not in acute exacerbation)
