respiratory conditions

Question 1

asthma and triggers

Answer 1

chronic inflammation of the airway in response to particular triggers. triggers
cold air, pollution, allergens
food allergens
resp infection, stress, exercise

Question 2

asthma patho

Answer 2

asthma inflammation —> bronconstriction, mucosal oedema and increase mucous production. —> increase airway resistance —? decreased gas exchange —> hypercapnia and hypoxia

Question 3

s/s and management of asthma

Answer 3

wheezing, coughing, chest tightness, SOB and increase HR.
Manage - broncodialotes and steroids

Question 4

cystic fibrosis what is it

Answer 4

autosomal recessive condition (need both recessive alleles)
gene codes for abnormal chlorine channels (Cl in and out of cell), this decreases Cl secretion into ECF (mainly mucous) which decreases water secretions in mucous making dry stick mucous which occurs throughout body

Question 5

CF affect on resp tract and Gi tract

Answer 5

resp - dry stick mucous —> decrease cilia action —> decrease clearance of debris (increase chronic infection) and microbes (increase airway resistance)

GI - dry sticky mucous –> decreased digestion and absorption —> malnutrition

Question 6

manage of CF

Answer 6

chest physio
bronchodialotr
mucolutics
prophylactic antibitoics
nutrient and enzyme supplement

Question 7

respiratory treatment

Answer 7

high flow oxygen
corticosteroids (anti inflammatory prednisone or hydrocortisone)
adrenaline to active sns
SpO2 and HR monitor

Question 8

beta agonist drugs and side effects

Answer 8

salbutamol - short acting and specific
salmeterol - long acting and specific
Terbutaline - short acting and specific
act as bronchodialotrs to relax smooth muscle
SE - palpitations, tremors, tachycardia, anxiety

Question 9

anticholingeric drug

Answer 9

ipratropium
bronchodialation
blocks receptors that cause bronchoconstriction
