16
Q

What is steatorrhea

A

excretion of abnormal quantities of fat with feces due to reduced absoprtion of fat by intestines

17
Q

How is CF diagnosed?

A

Quantitiative sweat chloride test
- CXR may reveal hyperinflation, mucus plugging and focal atelectasis

18

Maintenance: chest physiotherapy, hight-fat diet, supplement fat-soluble vitamins (A, D, E, K).
Acute exacerbations: antibiotics

19

institutionalization
advanced ageg
poor dentitition
alcohol
sedative use

ABG

21
Q

what is the presentation of nasal foreign body

A

persistent foul-smelling purulent unilateral nasal discharge in a young child without respiratory symtpoms

22
Q

What can be used with nasal foreign bodies to shrink the mucous membrane prior to removal of the FB

A

22
Q
A
23
Q

how are ocular foreign bodies diagnosed

A

full inspection of lids, conjunctiva and cornea
Slit lamp exam will assist in ID and removal

24
Q

What is hyaline membrane disease

A

when infants are born before the lungs are producing adequate amounts of surfactant

24
Q

What causes hyaline membrane disease

A

prematuraty
deficiency in sufactant resulting in poor lung compliance an dn atelectasis
