malfunctioning eustachian tubes
usually viral

bronchiolitis and RSV

Answer 19

common in infants
CM: fever, cough, wheeze, coarse lung sounds, tachypnea, lethargy, poor feeding
dx: nasopharyngeal swab
manage: NP suctioning, O2, hydration

Question 20

most common reason for hospitalization w RSV

Answer 20

dehydration
low O2 sat

Question 21

asthma

Answer 21

chronic inflammatory disorder
dx: pulm function tests
cause: genetics, 2nd hand smoke, being black, premature birth
risk factors for exacerbation: URI, allergies, exercise
CM: wheezing, diminished lung sounds, cough at night, breathlessness, chest tightness, feel better after rescue inhaler

Question 22

mag sulfate
steroids

Question 24

uncontrolled asthma can lead to

Answer 24

COPD

Question 25

long term controller meds

Answer 25

Question 26

quick release meds

Answer 26

asthma goal

Answer 27

less than 2 symptomatic days per week monitor function w peak flow meter (blow out hard and fast, do 3 attempts, zero out before each use, stand upright)

Question 28

cystic fibrosis

Answer 28

exocrine glands produce thick mucus that obstruct respiratory passages lethal, progressive genetic illness (autosomal recessive. need CTFR gene from both parents) dx: newborn screening, sweat chloride test (elevated Cl and Na) CM: meconium ileus, steatorrhea, weight loss, increased appetite, progressive COPD, repeated bouts of URIs, gradual resp deterioration, electrolyte deficiency manage: vigorous daily resp routine (chest physiotherapy, bronchodilator nebs), aggressive infection treatment, replace pancreatic enzymes w meals, high protein/high calorie diet, treat constipation, salt supplementation prognosis- 37.4 yrs can do lung, heart, liver, pancreas transplants
