1

unlabored breathing with nonproductive cough and expiratory wheeze

foreign body

2

best test to confirm foreign body

airway fluoroscopy

3

recurrent wheezing that increases with feeding and neck flexion

vascular ring

4

best test to diagnose vascular ring

barium swallow study

5

hypertrophic pulmonary osteoarthropathy aka

clubbing of fingers

6

pulsus paradoxus

difference >20 in BP between inspiration and expiration

7

chronic hypoxemia effect on kidneys

increased EPO so increased HCT and decreased platelets

8

chronic hypoxemia and respiratory drive

hypoxemia drives their respiratory drive so if you give them oxygen they may decompensate

9

best way to measure oxygenation with carbon monoxide poisoning

arterial blood gas (carboxyhemoglobin absorbs light the same as oxyhemoglobin so pulse ox won't be accurate)

10

blood measurement for oxygenation

must be arterial (capillary is not accurate for oxygenation)

11

test to distinguish pulmonary vs cardiac cause of cyanosis

hyperoxia test (after 10 minutes of 100% O2 PaO2 would increase in pulmonary disease but not cardiac)

12

iron in methemoglobinemia

is in the oxidized ferric state (Fe3+) so that it can't effectively unload oxygen to the tissues

13

best way to diagnose methemoglobinemia

cooximetry

14

common cause of methemoglobinemia in babies

topical anesthetics (benzocaine) for teething

15

methemoglobinemia treatment

remove exposure and/or IV methylene blue

16

pulse ox reading with methemoglobinemia

85% (methemoglobin absorbs both oxygenated and deoxygenated wavelengths)

17

loud brassy cough that is not present during sleep

psychogenic cough

18

FTT with low serum albumin, low sodium and pseudomonas infections

CF

19

diagnostic sweat test for CF

>60 meq

20

odds of a healthy sibling of someone with CF being a carrier

2/3

21

carrier rate of CF in caucasian population

1/25

22

newborn screen and CF

only 95% sensitive

23

newborn with hypoproteinemia, anemia, hypochloremic alkalosis, recurrent pulmonary symptoms and steatorrhea

CF

24

which symptoms of CF are more prevalent in infants

GI more so than pulm (meconium ileum, unconjugated hyperbilirubinemia)

25

vitamin supplementation in CF

vitamin D by 5 years old

26

coags in CF

prolonged PTT from vitamin K malabsorption

27

pseudocyst on xray in newborn

meconium peritonitis - think CF

28

bacteria with advanced CF that is associated with worsening lung function na poor overall outcome

burkholderia cepacia

29

treatment choice for acute pulmonary exacerbations with CF

aminoglycoside and penicillin derivative (ex: piperacillin)

30

R ventricular dysfunction when pulmonary vascular resistance is elevated

cor pulmonale
