Q

What is breathing like in kids less than 6/7 years old?

A

Breathing is less rhythmic and diaphragmatic or abominal.

Periodic breathing in infants.

Assessment: have to check RR for a full minute

Respiratory rate is higher (increased metabolism) and responds dramatically to emotion, illness, fever and exercise.

Q

What are peds characteristics that affects the respiratory system? (5)

A
  1. Respiratory tract has narrow lumen until 7~8 years old
  2. Fewer alveoli until age 12
  3. Respiraotry muscles are weaker, there is smaller vital capacity, thus less reserve
  4. Immune system is immature (less lymphoid tissue)
  5. Young children may have more severe symptoms

Know the baseline, is the child getting worse or better?

Look at respiratory pattern

}RR 70 to 80 for 2 days and is now 60

}Child wheezing last few days and now with decreased/absent wheeze

}Changes in oximetry (feeding, activity, rest)

}Apnea

Q

What are 4 teaching points of managing nasopharyngitis?

A

}Home management with antipyretics, bulb suctioning as indicated, Normal Saline (NS) nasal drops, maintaining adequate fluid intake & comfort measures

}Teach parents signs of respiratory complications and when to seek medical attention

}Recurrent URI’s very common in children less than three years. As exposure & immunity increases, frequency drops.

}Ear infections commonly occur with/after a URI and signs of infection should be reported to provider.

Q

How useful could cool mist be? What is a risk of it?

A

}Cool mist safer (decreased risk burns) with no evidence of advantage to steam

}Both promote a more comfortable environment; loosen secretions

}They DO NOT decrease viscosity of secretions

}Risk for growth of organisms exists in both (less with cool water)

}NS Nebs (may loosen secretions, so it’s easier to suck out secretions, and open the airway)

Q

Why is routine use of decongestants not recommended?

What about vasoconstrictive nose drops?

A

}Routine use not recommended for infants and young children. It’s because they can be overdosed. It can also increase HR, and that should be avoided.

}Use of vasoconstrictive nose drops such as Neo-Synephrine can have rebound congestion if used more than 3 days

22
Q

80 to 90% of pharyngitis are viral, however you need to rule out strep throat because

A

you need to treat it accordingly.

Group A beta hemolytic streptococci can cause pharyngitis.

23
Q

Unilateral nasal discharge with frequent sneezing should alert the nurse to suspect?

A

Obstruction of some type in the nose

24
Q

Sudden coughing with high-pitched wheezing sounds may be related to what nursing diagnosis?

A

}Foreign body ingestion. Could have gone down trach instead of esophagus.

25
Q

What is Croup Syndrome?

A

A group of symptoms that includes hoarseness, resonant cough that’s barky or brassy, inspiratory stridor, and respiratory distress

26
Q
A
27
Q

What does croup syndrome affect?

A
  1. Larynx
  2. Trachea
  3. epiglottis
  4. bronchi

Inflames the mucosa lining of larynx, and teachea, causes narrowing of airway. The area affected is often age related.

}Child attempting to inhale past the obstruction produces characteristic inspiratory stridor, suprasternal retractions & barky seal like cough.

28
Q

What are the causes of croup?

A

They’re often viral.

Causes: parainfluenza, RSV, influenza A &B, mycoplasma pneumonia

29
Q
A
30
Q

What is Epiglottis?

Causes?

A

Bacterial form of croup, H influenza.

usually caused by H influenza type B or strep pneumonia

31
Q
A
32
Q

What occurs to the body when a person has epiglottitis?

A

Inflammation and swelling of epiglottis; partial upper airway obstruction.

Occurs frequently between ages 2 to 8.

Onset is abrupt

33
Q

What are assessments for epiglottis?

A
  1. }Progressive stridor
  2. }Severe respiratory distress
  3. }Hypoxia/dyspnea
  4. }Refuses to swallow/drooling due to very sore throat
  5. }Sits up/leans forward with chin thrust out (tripod position)
  6. }Cyanosis/pallor
  7. }Decreased LOC
  8. }Rapid onset and progression
  9. Diagnosis based on history, symptoms, culture, lateral neck x-ray shows rounded & enlarged epiglotti
34
Q

What are 3 Lower Respiratory Tract illnesses?

A
  1. Bronchitis
  2. Bronchiolitis (RSV)
  3. Pneumonia
35
Q

How could you prevent epiglottis?

A

HIB Vaccine

36
Q
A
37
Q

Why are kids prone to Lower Resp Illnesses?

A

Cartilaginous suport of large airways are not fully developed until adolescence. So the smooth muscle in structures causes constriction of airway, esp bronchioles.

38
Q

What type of inflammation is occurring in Bronchiolitis?

A
  • Tissue edema and mucous plugging occurs
  • The viral infection affects small airways
  • Inflammation of bronchioles prevents air from leaving alveoli r/t narrowing of air passages and mucous and exudate. Airway trapping occurs in small air passages
  • Inflammation leads to necrosis and sloughing of epithelium into airway lumen
39
Q

Assessments for RSV (Respiratory Syncytial Virus)

A
  1. }Lower airway infection usually follows URI
  2. }Dry, persistent cough with dyspnea
  3. }Tachycardia and tachypnea
  4. }Retractions
  5. }Fever (100 to 101) OR (37.8 to 38.4)
  6. }Thick nasal secretions (ineffective airway clearance)
  7. }Difficulty with feedings, irritability
  8. }Expiratory grunts & wheezes
  9. }Can lead to pneumonia if untreated
  10. }RSV confirmed by viral culture (nasal swab)
40
Q

What are nursing interventions for RSV?

A

◦Monitor respiratory status, LOC, (detect early signs worsening condition, signs hypoxia)

◦Humidified oxygen (alleviate hypoxia & moisten secretions)

◦Maintain adequate hydration (keep secretions thin so can expectorate)

◦Emergency equipment at bedside (condition can deteriorate rapidly)

◦Keep Jack as quiet as possible (crying aggravates laryngospasm and increases hypoxia; rest Ô metabolic need for oxygen)

◦Position Jack upright with HOB elevated or held by parents (decrease pressure from abdominal contents on diaphragm)

41
Q

How is CF deterimental?

A
  1. }There is an increased viscosity of mucous gland secretions causing mechanical obstruction, that results in a cascade of clinical manifestations.
  2. }Mucous glands produce thick mucoproteins obstructing small passages in selected organs such as pancreas & bronchioles.
  3. }Earliest manifestation of CF may be a meconium ileus in newborn, where small intestine is obstructed by thick, puttylike, mucousy meconium.
42
Q

What are 4 ways to diagnose CF?

A
  1. }Sweat chloride test result of > 60 mEq/L
    Test indicated for children with recurrent respiratory infections, malabsorption or FT
    ◦Nail/Hair analysis (á Na)
    ◦Child tastes salty
  2. }New methods for diagnosis in infancy (including NB screening)
  3. }Malabsorption
    ◦High level of fecal fat
    ◦Most food passed undigested increasing # stools
    ◦Solids added; stools become frothy, fatty & foul smelling◦
  4. }Frequent respiratory infections
43
Q

Why are pulmonary complications from CF so serious?

A

Increased viscosity of mucous gland secretion causes thick &

stagnating mucous & bacterial colonization resulting in destruction

of lung tissue. Pulmonary complications are most serious and life-

threatening aspect of CF.

44
Q

What are 3 primary goals with CF?

A
  1. Prevent/Minimize Pulmonary complications. i.e ineffective airway r/t pulmonary secretion. Or impaired gas exchange r/t air trapping
  2. Optimize growth and nutrition
  3. Support child and family in management of chronic illness
45
Q

What are 6 ways to manage CF?

A
  1. Chest physical therapy
    Enhance removal of thick mucous
    Device includes mechanical precursors, flutter valve and therapy vest
  2. Exercise
  3. Aerosol Therapy: Bronchodilators neb vest. May cause voice alteration and laryngitis
  4. Oxygen Therapy for acute episodes
  5. Ibuprofen for anti inflammatory effects: must monitor for adverse effects
  6. Transplantation: doesn’t cure CF
46
Q

What is asthma?

A
47
Q

What occurs to the airways during an asthma exacerbation?

A
  • Lining of airways becomes swollen
  • airways produce a thick mucus
  • muscles aroudn the airways tighten and makes the airway narrower
48
Q

What are Medications for long term control (preventive) of asthma? (3)

A
  1. NSAID: cromoyn
  2. Long acting beta agnoist: solmeterol (servent)
  3. Leukotrienes: Inflammatory mediators (montelukast)
49
Q

What are quick relief medications for asthma? (Rescue Meds)

A
  1. Corticosteroids: anti inflammatory
  2. Short acting beta adrenergic agonist : albuterol. Relaxes smooth muscle of airways
  3. Anticholinergics: atrovent (Ipatropium)
50
Q

What is pertussiss?

Why does it typically occur?

A

Pertussis is the whooping cough.

Acute infection usually in younger non immunized children.

High rate mortality and morbidity
