Demo Test

1. In which 2 leads on a 12 lead can you commonly identify a Left Bundle Branch Block (LBBB)?

Leads V3, V5

Leads V5, V6

Leads V2, V3

Leads V2, V6

2. You and your AEMT partner are dispatched to a 34-year-old male with chest pain. As you approach the patient you notice he is breathing fast and holding his chest. He is able to talk to you in complete sentences and does not appear to have a diminished LOC. He states he has been under a lot of emotional stress with work and just found out his girlfriend is pregnant. He also tells you he does not have a cardiac history and feels light headed. Your partner obtains a set of vital signs while you attach a cardiac monitor. Your partner relates that the patient is breathing at 27 breaths per minute, has a blood pressure of 98/62, and a rapid pulse. Once you have the monitor attached you observe sinus tach at 175 beats a minute with a narrow QRS. After attaching oxygen and having your partner start an IV, what would be the next appropriate intervention?

Ask the patient "to bear down" in an attempt to slow the heart rate

This patient is symptomatic and needs to be cardioverted immediately

Administer 6mg of Adenosine, rapid push followed by a 20cc flush

There is nothing more you can do for this patient besides rapid transport

3. You are performing CPR on a man in cardiac arrest. Which of the following choices would you administer first?

Vasopressin 20 units

Atropine 1mg

Epinephrine (1:10000) 1mg

Vasopressin 40 units Vasopressin 40 units

4. If a patient has a positive QRS in Lead I and a negative QRS in Lead AVF, how would you describe their Axis Deviation?

Normal Axis Deviation

Left Axis Deviation

Extreme Right Axis Deviation

Right Axis Deviation

5. Your cardiac arrest patient has a return of spontaneous circulation. The patient's blood pressure has dropped below 90 systolic and medical direction has ordered an Epinephrine infusion. What is the correct formula?

1-5 mcg/kg per minute

.01-.05 mcg/kg per second

.1-.5 mcg/kg per minute

10 mg over a 20 minute period

6. What is the first dosage of adenosine that should be given?

2 mg per kilo pushed by IV with a 50 cc fluid bolus

10 mg rapid IV push followed by a 100 cc fluid bolus

20 mg rapid IV push followed by a fluid bolus of 100 cc

6 mg rapid IV push followed up by a 20 cc fluid bolus

7. You have successfully defibrillated a patient in ventricular fibrillation. The patient has a return of spontaneous circulation but is still unresponsive. Which of the following would be most appropriate in your care?

Administer 150mg of Amiodarone

Hyperventilate the patient

Begin Targeted Temperature Management protocol

Start a dopamine drip if blood pressure is under 100 systolic

8. What is the correct conduction rate of the rhythm strip below?

1:1

2:1

3:1

2:2

9. What range of degrees is Extreme Right Axis Deviation?

0 to 90 degrees

0 to -90 degrees

90 to 180 degrees

-90 to -180 degrees

10. You are assessing a patient who has a blood pressure of 105/60, pulse is 101 and respirations are at 19. They state that if they stand up after lying down for a while they get dizzy and feel like they are going to pass out. This patient is most likely suffering from:

Pulsus Paradoxes

Orthostatic Hypotension

Levine's Sign

Battle's Sign
