Medical Emergencies

Question 1

drug that slows tachycardias. Acts directly on sinus pacemaker cells and vagal nerce terminals

Answer 1

Adenosine

Question 2

the drug of choice for paroxysmal supraventricular tachycardia (PSVT)

Answer 2

Adenoside

Question 3

this drug increases the heart rate

Answer 3

atropine

Question 4

drug used in bradycardia rhythms to increase the heart rate. Also used in asystole

Answer 4

Atropine

Question 5

has different effects at precise dosage levels. Greater than 10mcg/kg/min it has Alpha properties used to treat hypotension. At low dosage, 1-3mcg/kg/min it has dopaminergic properties that result in vasodilation of renal, messenteric, and cerebral arteries. At dosages between 3-10mcg/kg/min it has beta-1 properties, similar to dobutamine.

Answer 5

dopamine

Question 6

drug used for treatment of hypotension that is not volume related. First line drug for hypotension.

Answer 6

dopamine

Question 7

dopamine doses greater than 10mcg/kg/min are used for what?

Answer 7

alpha properties; hypotension

Question 8

dopamine at low dosage, 1-3mcg/kg/min is used for:

Answer 8

dopaminergic properties that result in vasodilation of renal, messenteric, and cerebral arteries

Question 9

Improved coronary and cerebral profusion is the primary beneficial effect of this drug during cardiac arrest. May also increase automaticity and make VF more susceptible to DC countershock.

Answer 9

Epinepherine

Question 10

the first drug of choice of all ACLS situations where the patient is pulseless, dead!

Answer 10

Epinepherine

Question 11

this drug suppresses ventricular tachycardia, and ventricular fibrillation

Answer 11

lidocaine

Question 12

this drug is the first line antiarrhythmic drug; used to treat PVC’s, Ventricular Tachycardia, and Ventricular Fibrillation.

Answer 12

lidocaine

Question 13

initial treatment for managing dysrhythmias. Also probably helpful for refractory ventricular fibrillation and ventricular tachycardia after administration of lidocaine or bretylium doses.

Answer 13

Magnesium Sulfate

Question 14

this drug stimulates alpha-, beta1-, and beta2-adrenergic receptors in dose-related fashion

Answer 14

norepinephrine

Question 15

this drug is indicated for non-volume related hypotension. (Systolic blood pressure less than 70mmhg, in a non-volume depleted patient). Also used for the treatment of cardiogenic shock (systolic B/P < 70 mmHg)

Answer 15

norepinephrine

Question 16

used in hypoxemia or suspected hypoxemia. Used as one of the first line treatments in all ACLS Situations. Has been proven to decrease the workload on the myocardium.

Answer 16

Oxygen

Question 17

works by inhibiting the movement of calcium ions across cell membranes. this drug decreases atrial automaticity, reduces AV conduction velocity, and prolongs the AV nodal refractory period. In addition, verapamil depresses mvocardial contractility, reduces vascular smooth muscle tone, and dilates coronary arteries in normal and ischemic tissues.

Answer 17

Verapamil

Question 18

this drug is used as an antidysrhythmic and antianginal agent. Primarily used in PSVT, atrial flutter with a rapid ventricular response and atrial fibrillation with a rapid ventricular response

Answer 18

Verapamil
