04
Front
How should a LABA be used for asthma?
Back
For asthma, a LABA should be used with an inhaled corticosteroid, not alone as monotherapy.
05
Front
How does ipratropium produce bronchodilation?
Back
Ipratropium blocks muscarinic receptors, reducing cholinergic bronchoconstriction.
06
Front
What eye-related risk can occur if ipratropium spray gets into the eyes?
Back
Ipratropium spray entering the eyes can increase intraocular pressure and may precipitate or worsen narrow-angle glaucoma.
07
Front
Why does theophylline require careful monitoring?
Back
Theophylline has a narrow safety margin and variable clearance, so careful monitoring is important.
08
Front

Back
Theophylline toxicity may cause persistent vomiting, arrhythmias, and seizures; suspected toxicity needs prompt clinical evaluation.
09
Front
How can ciprofloxacin affect theophylline levels?
Back
Ciprofloxacin can reduce theophylline clearance, raising theophylline levels and toxicity risk.
10
Front
What electrolyte change can occur with higher beta₂-agonist exposure?
Back
Higher beta₂-agonist exposure can lower serum potassium and contribute to cardiovascular effects.
11
Front
Are LABAs intended for immediate relief of sudden symptoms?
