Question | Answer |
Characteristic triad of asthma | - Airway inflammation - Airway hyper-responsiveness - Reversible airflow obstruction |
Extrinsic vs. intrinsic asthma | Extrinsic (most) - IgE produced to environmental antigens; associated with eczema, hay fever; starts young Intrinsic - not related to atopy or environmental triggers |
What movement of the abdomen/diaphragm is a sign of impending respiratory failure? | Paradoxic movement of abdomen and diaphragm on inspiration |
Most common physical exam finding in asthma | Wheezing |
On pulmonary function testing, when is airflow obstruction considered reversible? | If inhalation of β2-agonist increases FEV1 or FVC by at least 12% |
Asthma patients should self-monitor their ____________. | peak flow (peak expiratory flow rate) |
Peak flow monitoring for patients with mild persistent asthma: 1) How often? 2) What to do if it decreases | Periodic monitoring is sufficient Increase dose of inhaled steroid if decreases |
Peak flow monitoring for patients with moderate persistent asthma | Daily monitoring required Increase dose of inhaled steroid if decreases |
Peak flow monitoring for severe persistent asthma patients | Daily monitoring is required Initiate prednisone if decreases |
CXR in asthma | Normal in mild cases May have hyperinflation if severe Only necessary to get a CXR if asthma is severe (to rule out other conditions) |
T/F: Hypercarbia is common in asthma patients. | False; HYPOcarbia is common. If PaCO2 is normal or increased, respiratory failure may ensue |
What blood pressure meds should be avoided in asthmatics? | β-blockers |
Role of IV magnesium in asthma | Helps with bronchospasm in acute severe exacerbations that don't respond to other meds (inhaled β2-agonists or corticosteroids) |
In patients with asthma and nasal polyps, you should consider _________ as a diagnosis and avoid _______________. | Aspirin-sensitive asthma Avoid aspirin or any NSAIDs, which may cause a severe systemic reaction |
T/F: An MDI with a spacer is just as effective as a nebulizer | True BUT patients may report greater symptomatic relief with a nebulizer simply because it provides more medication |
