Q

What is the Yellow Zone for Peak flow?

A

<80% but >50% of the patients best

  • if this happens, have the patient take a dose of their rescue inhaler and repeat
  • On repeat, there should be a 20% + improvement
  • Medications may beed to be evaluated

Q

If control is not achieved in 3-6 months, what is the appropriate next step?

A

Referral

19
Q

When a child has a foreign body, how can you tell if it is upper or lower based on clinical sxs?

A

Upper: Coughing and strider
Lower: Coughing and wheezing with unilateral decreased breath sounds, with retractions/accessory muscle use

20
Q

With a high suspicion of a foreign body, what is the study of choice?

A

Rigid bronchoscopy: allows for removal at the time of visualization

21
Q

Which of the following is NOT true regarding Cystic Fibrosis?

  1. CF is autosomal dominant
  2. It is an abnormality of the CF conducting regulator that affects chloride channels effecting movement of salt across the cell
  3. Children often present with FTT
  4. Confirmation of CF dx is done with a Pilocarpine sweat test
A
  1. is NOT true: CF is autosomal recessive

Note: >60 mmol for the Pilocarpine sweat test

22
Q

What is the CF “quad” seen in children? (You made up “quad”)

A
  1. Meconium ileus*
  2. Later have FTT WITH foul smelling stools
  3. GERD
  4. Clubbing
23
Q

What bacteria becomes predominant in CF patients?

A

Pseudomonas aeruginosa

24
Q

What is the leading cause of death in pre-term infants?

A

Infant Respiratory Distress Syndrome/Hyaline Membrane Disease
(IRDS)

25
Q

What are the 3 main causes for Hyaline membrane disease?

A
  1. Developmental insufficiency of of pulmonary surfactant production and structural maturity in the lungs
  2. Neonatal infection
  3. Genetic problem with the production of surfactant associated proteins
26
Q

What are the risks of developing IRDS?

A

Risks decrease with advancing gestational age:

  1. 50% chance with infants born at 26-26 weeks
  2. 25% chance with infants born at 30-31 weeks
  3. More frequent with children born to diabetic mothers
  4. the second born of premature twins
27
Q

You are performing a newborn exam on a 26-week infant in the hospital. Vital signs reveal tachypnea, tachycardia and high CO2. On PE, you notice nasal flaring, grunting, and some cyanosis. What would you expect to see on a chest x ray?

A

“Bell shaped chest”

-IRDS

28
Q

You are performing a newborn exam on a 26-week infant in the hospital. Vital signs reveal tachypnea, tachycardia and high CO2. On PE, you notice nasal flaring, grunting, and some cyanosis. What is the most appropriate management?

A

PREVENTION is the best tx: in premature births, giving mother steroids can increase rate of surfactant production

  • O2 via CPAP and surfactant
  • Infant may need ET tube and ventilation
29
Q

What is Acute Bronchiolitis?

A

Nonspecific inflammation of the bronchioles

30
Q

A 1 year old infant is seen in the clinic. Vital signs reveal an increased RR. On PE, you hear rhonchi and wheezing; you see retractions while the patient is breathing. Parents say their child has had a cough for about 2-3 days. What is the most common cause of this child’s condition?

A

Usually caused by RSV or Adenovirus

31
Q

A 1 year old infant is seen in the clinic. Vital signs reveal an increased RR. On PE, you hear rhonchi and wheezing; you see retractions while the patient is breathing. Parents say their child has had a fever, cough, and runny nose for about 2-3 days. What is the most appropriate treatment for this patient?

A

Supportive: Albuterol and O2; cool mist humidifier

  • RSV is self limiting
  • If there is a pneumonia –> treat
  • Steroids may be used in severe cases
32
Q

What is the MCC of pneumonia in children <2 y/o?

A

Viral:

  • RSV
  • Parainfluenza
  • Influenza A/B
  • Human metapneumovirus
33
Q

What is the difference between a pneumonia CXR and a bronchiolitis CXR?

A

Pneumonia: perihilar streaking, increased interstitial markings, peribronchial cuffing

Bronchiolitis: “patchy pneumonia”? and HYPERINFLATION

34
Q

What is the MC bacterial cause of pneumonia in neonates?

A
  1. Group B strep***

2. Chlamydia

35
Q

What is the MC bacterial cause of pneumonia in children older than neonate age?

A
  1. Strep pneumo***
  2. Hib
  3. M. cat
  4. Staph
  5. Klebsiella
  6. E. coli
36
Q

What are the following findings consistent of:

  • Increased vocal fremitus
  • Dullness to percussion
  • Tachypnea
  • Tachycardia
  • Fever with productive cough* (part of hx)
A

Bacterial pneumonia

37
Q

What is the most appropriate tx for bacterial pneumonia for a <4 wk old infant?

A

-admission for Gentamicin and Ampicillin

38
Q

What is the most appropriate tx for bacterial pneumonia for a 3months to 5 yrs old child?

A

-Amoxicillin 50-90 mg/kg/d x 7-10 days

39
Q

What is the most appropriate tx for bacterial pneumonia for a child >5y/o?

A

-Amoxicillin, Macrolide, or Penicillin G can all be effective based on the pathogen

40
Q

What is “lobar consolidation” consistent with on CXR?

A

bacterial pneumonia

41
Q

What CXR finding is the classic hallmark of Croup?

A

Steeple sign = Supraglottic narrowing

42
Q

A 4 year old child is seen in the office with a balky, seal cough. You notice stridor while the child is breathing. Vital signs reveal a low grade 99 degrees fever. What is the most likely cause of this condition?

A
  • Croup

- Parainfluenza virus***

43
Q

A 4 year old child is seen in the office with a balky, seal cough. You notice stridor while the child is breathing at rest. Vital signs reveal a low grade 99 degrees fever. What is the most appropriate tx for this child?

A
  • Supportive therapy
  • Hydration and O2
  • Nebulized racemic epinephrine***–used when pt has resting stridor
