This type of inhaler is used for quick relief of asthma symptoms.

What is a short-acting beta-2 agonist (SABA)?


100

What are sodium channels?



100

This system classifies drugs based on their action on cardiac conduction.


What is the Vaughan-Williams classification? 



100

This neurotransmitter is often called the “feel-good” chemical and regulates mood, sleep, and appetite.


What is SEROTONINNNN :))))))))))

100

This waveform represents atrial depolarization on an EKG.


What is the P-wave?

200

These drugs block histamine H1 receptors to reduce sneezing, itching, and urticaria.


What are antihistamines?

200

Beta-blockers fall into which anti-arrhythmic class?


What is Class II?



200

Class II anti-arrhythmics reduce heart rate primarily by decreasing this node’s conduction velocity.


What is AV node conduction?



200

GABA primarily exerts this effect on the nervous system.


What is inhibitory, calming (basically chilling)?
200

The QRS complex represents this part of the cardiac cycle.


What is ventricular depolarization? 

300

Inhaled corticosteroids reduce airway inflammation by inhibiting transcription of these pro-inflammatory molecules.


What are cytokines and inflammatory cells (ex: eosinophils, mast cells, etc).



300
