Q

How does the size of a child’s respiratory tract impact influence their response to respiratory conditions?

A

Their anatomy is shorter compared to an adult. It is easier for organisms to reach the respiratory tract and cause infection. A smaller airway diameter increases risk of airway obstruction and increased secretions

A

Epstein-Barr virus (EBV) is the principal cause of infectious mononucleosis
through Contact with saliva (mildly contagious)

44
Q

True or False? When a child is suspected to have epiglottitis the nurse should attempt to visualize the epiglottis.

A

False. Visualization of the epiglottis should not be done by a nurse. Children with suspected epiglottitis should only be examined in a setting where emergency personnel are ready to intubate in case of further obstruction.

Paroxysmal (any sudden, uncontrollable outburst; a fit of emotion or action) attacks of laryngeal obstruction
Occur mostly at night- sit outside to breathe cold air to stop the cough
Child usually feels well the following day

49

69
Q

What changes occur to the alveoli in Acute Respiratory Distress Syndrome (ARDS)?

A

In ARDS, the lungs become very stiff (the surfactant that helps the alveoli move, expand and contract is inactive)
Improper gas exchange because alveoli cannot open up
Mucosa starts to swell and atelectasis can occur
