Drug Classes

Question 0

Albuterol

Answer 0

Sympathetic Agonist

Sympathomimetic bronchodilator selective direct acting B2 agonist

Bronchial Asthma, emphysema, chronic bronchitis, allergic bronchospasm

Question 1

Adenosine

Answer 1

Anti arrhythmic

Slows AV conduction

Ind: symptomatic PSVT, incl. Wolff-Parkinson-White Syndrome

Question 2

Amiodarone

Answer 2

Anti arrhythmic

Slows action potential and refractory rate, slows sinus rate, increases PR and QT intervals. Decreases peripheral vascular resistance.

Ind: Vtach and Vfib

Question 3

Aspirin

Answer 3

Platelet aggregate inhibitor
Analgesic 
NSAID 
Antipyretic 
Salicylate 

Anti inflammatory, blocks platelet function

Question 4

Atropine

Answer 4

Anticholinergic, antimuscarinic, parasympatholytic

Decreases vagal tone resulting in positive chronotropic effect. Increases AV conduction.

Competitive antagonist for acetylcholine at muscarinic receptors.

Bronchodialates via parasympatholytic mechanism.

Ind: hemodynamically significant bradycardia. Cholinergic poisoning.

Question 5

Diphenhydramine

Answer 5

Antihistamine (with anticholinergic and sedative effects)

Prevents (does not reverse) histamine mediated response (particularly on the smooth muscles of the airway, GI tract, uterus, and blood vessels)

Question 6

Calcium Chloride

Answer 6

Electrolyte

Increases cardiac contractility

May increase or decrease vascular resistance

Question 7

Cardizem

Answer 7

Calcium channel blocker

Slows conduction through AV node
Causes vasodilation

Question 8

Naloxone

Answer 8

opioid antagonist

Half life of 30-80 minutes (average 60)
