Questions and Answers
What is the class of epinephrine?
What is the class of epinephrine?
- Catecholamine, sympathomimetic, alpha 1, beta 1, and beta 2 adrenergic agonist and histamine antagonist (correct)
- Alpha 1, Alpha 2 and beta 1 adrenergic agonist
- Beta 1 and beta 2 adrenergic agonist
- Alpha 1, beta 1, HT3 and beta 2 adrenergic agonist
What is the mechanism of action of Adenosine?
What is the mechanism of action of Adenosine?
- Stimulates beta receptors, causes positive inotropy, chronograph and dronotropy, leading to Supra ventricular tachycardia if not given in small doses.
- Acts on alpha receptors, causes vasoconstriction by increasing ADH.
- Inhibits histamine receptors, causes a reduction of swelling and inflammation in anaphylaxis and allergic reactions.
- Adenosine works by slowing down atrioventricular conduction, resulting in cardioversion. By slowing down atrioventricular conduction, the reentry pathway becomes terminated, resulting in the SA node taking over electrical conduction as the primary pacemaker. (correct)

Study Notes
- Epinephrine is a catecholamine indicated for anaphylaxis, cardiac arrest, bradycardia, and asthma. It binds to adrenergic and histamine receptors, providing positive effects on the heart and bronchial smooth muscle, and increasing blood pressure.
- Lidocaine, an antidysrhythmic, works by blocking sodium channels to decrease excitability in ventricular dysrhythmias. It is used for various tachycardias and premature complexes.
- Adenosine, an endogenous nucleotide, is used for supraventricular tachycardia by slowing atrioventricular conduction and allowing the SA node to take over.
- Amiodarone, an antidysrhythmic, blocks sodium, potassium, and calcium channels to treat ventricular dysrhythmias by slowing heart rate and prolonging cardiac segments.
- Atropine, an anticholinergic, is indicated for bradycardia and poisoning by blocking acetylcholine on the SA node and other organs.
- Nitroglycerin, a vasodilator, is used for chest pain and heart failure by dilating coronary vessels and reducing heart workload.
- Magnesium sulfate is used for hypertension, seizures in pregnancy, and cardiac dysrhythmias by relaxing muscles and blocking acetylcholine release.
- Ipratropium bromide is a bronchodilator used for asthma and bronchitis by blocking acetylcholine on bronchial smooth muscles.
- Albuterol sulfate is a bronchodilator used for respiratory diseases by binding to beta 2 receptors and relaxing bronchial smooth muscles.
- Acetylsalicylic acid is an antiplatelet indicated for chest pain and heart conditions by preventing blood clot formation through thromboxane A2 inhibition.
- Diltiazem, a calcium channel blocker, is used for atrial dysrhythmias by reducing calcium influx and slowing cardiac conduction.
