1
Q

A

It is more likely to affect their bronchioles –> Different terminology

Q

What are croup syndromes? What do they look like?

A

Affect upper Respiratory tract - pharynx, epiglottis, larynx, trachea, tonsils, middle ear (otitis media)

Characterizes by sudden onset of harsh, barking cough. Often inspiratory stridor with hoarseness and sore throat.
Causes mild to severe respiratory distress.

Q

Mucosal inflammation/edema, accompanied by bronchioles becoming constricted during expiration occurs during which illness process? What does this lead to?

A

Bronchiolitis
–> Air trapping + hyperinflation
–> Atelectasis with complete obstruction

Impaired gas exchange results in metabolic acidosis and mild respiratory alkalosis

Q

Chest overexpansion, rhinorrhea, and crackles are common in which airway issue in children?

A

Bronchiolitis
–> Alterations in behaviour and LOC is sign of cyanosis

22
Q

What does the course of RSV look like?

A

Peaks at day 3-5 and lingers for 2-4 weeks.

23
Q

What is most important of treatment for bronchiolitis?

A

Oxygen and hydration
–> We want to increase efficacy and decrease resp effort to prevent exhaustion

24
Q

Influenza is most severe in which age group?

25
Q

A child presents with dry throat, dry cough, is flushed and fevered with chills, has photophobia, myalgia and a lack of energy. What does this resemble?

26
Q

How long does influenza last?

27
Q

What bacteria causes pertussis or whooping cough?

A

Bordetella pertussis

28
Q

Pertussis is highly contagious and has a high risk to young infants. It has a high morbidity and risk of mortality. How is it prevented?

A

Vaccination
–> Lifelong immunity after infection

29
Q

What is the usual etiology of pneumonia in children?

A

Viral - RSV/influenza most common

May also be bacterial or aspiration

30
Q

What is the normal respiratory rate for a three year old?

31
Q

What is the normal respiratory rate for a school aged child?

A

3-6: 20-25
6-12: 14-22

32
Q

What is the normal respiratory rate for a youth (12+)

33
Q

What are the goals of care in a child with a respiratory tract infection?

A

To decrease respiratory effort, prevent exhaustion, and/or increase efficacy

34
Q

What is the most serious croup disorder? What causes it?

A

Acute epiglottitis due to high risk of airway obstruction
–> caused by haemophilus influenzae

35
Q

What is Otitis media?

A

Fluid in middle ear alongside acute illness and symptoms of middle ear infection

36
Q

What causes mononucleosis? What symptoms are associated with it?

A

Caused by Epstein-Barr Virus
–> Fever, exudative pharyngitis, lymphadenopathy, hepatosplenomegaly, and increased atypical lymphocytes.

37
Q

Which structures can be affected by croup syndromes?

A

Larynx, trachea, bronchi, epiglottis, pharynx (upper airway)

38
Q

What age group is usually effected by acute larygotracheobronchitis?

A

Children under 5

39
Q

What age is usually affected by acute spasmodic laryngitis?

A

1-3 years of age.

40
Q

What is the most common kind of croup?

A

Laryngotracheobronchitis

41
Q

Do children develop immunity to RSV?

A

No, re-infections are common

42
Q

What are the long-term effects of bronchiolitis?

A

Infection in the first year of life Increases the risk of childhood asthma

43
Q

What age group is typically effected by bronchiolitis?

A

Children ages 2-12 months, rare after 2 years

44
Q

What is tamiflu?

A

Antiviral that can be given in early infection of influenza to prevent severe infection.

45
Q

When is RSV season?

A

Q

What is a congenital diaphragmatic hernia?
