B.  Cannot be given via ET tube.

C.  Has a maximum total dosage of 3 mg IV in the setting of cardiac arrest     

D.  When given IV for unstable bradycardia, should always be given slowly

B.     2-10ug/min

C.     2-10ug/kg/min

D.      0.5mg-1.0mg IV

4. Atropine may:

1. Be given via the endotracheal tube

2. Be ineffective in second-degree and third-degree atrioventricular block

3. Result in undesirable tachycardia

4. Increase the rate of sinus bradycardia

A.    1,2,3

B.     1,3,4

C.     2,4

D.    All the above

5. A Dopamine infusion at 20ug/kg/min will likely result in:

A. Depressed myocardial contractility

B. Peripheral arterial vasoconstriction

C. Renal arterial vasodilatation

D. Respiratory depression

6. In contrast to other catecholamines, Dopamine at low doses (1-2ug/kg/min) can be expected to result in:

A.    An increase in blood pressure

B.     Gangrene

C.     Renal vasodilation

D.    Tachycardia

7. Match the following EKG changes with the appropriate block:  Regular rhythm, P waves before each QRS, PR interval is prolonged beyond 0.20, Usually no treatment is indicated unless the patient is symptomatic

A.    Third degree heart block

B.     Mobitz II

C.     Second degree heart block type I

D.    First degree AV block

8. Match the following EKG changes with the appropriate block:  There is complete absence of conduction between the atria and the ventricles causing the atria and the ventricles to beat independently of one another
