,Question 5
Atrial Flutter
Correct Answer
Pacemaker irritable focus issues impulse conducted in rapid, repetitive fashion. AV
node blocks some impulses from being conducted through protecting ventricles
from receiving too many impulses.
•Regular: Atrial rhythm regular ventricular may be regular or irregular depending on
pattern
•Rate: Atrial 250-350 beats/min. Ventricular depends on ratio of impulses
•P-Wave: atria's flutter producing series of well-defined P waves
•PRI: often impossible to determine PRI in this arrhythmia
•QRS: <0.12 seconds.



Question 6
Sinus Rhythm
Correct Answer
SA node is pacemaker firing at regular rate 60-100.
•Regular: Rhythm is regular.
•Rate: Heart rate between 60-100 beats per minute.
•P-Wave: P waves are uniform. One P wave in front of every QRS.
•PRI: Between.12 to .20 seconds; PRI constant across the strip.
•QRS:<.12 seconds.



Question 7
What kind of probes are low frequency?
Correct Answer
Phased Array and Curvilinear

,Question 8
Airway suctioning: min, better, best
Correct Answer

•Minimum: Manual suction device or improvised suction device, such as a 25cm
length portion of IV tubing connected to a 60mL syringe

•Better: Open suction tube, suction machine

•Best: Closed inline suction tube, suction machine



Question 9
Pre-Anesthesia Checklist - Suction: min, better, best
Correct Answer

•Minimum: Improvised Suction with Syringe (20cc or larger) and NPA. Patient
positioning if not contraindicated

•Better: Manual suction bulb with adapter

•Best: Powered commercial suction with oral tip and in-line endotracheal tube
suction adapter



Question 10
Describe Calcium Administration
Correct Answer
1 gm of Calcium (30mL of 10% Calcium Glucose; 10mL of 10% Calcium Chloride)
IV/IO after 1 unit of blood; repeat dose after every 4 units of blood product



Question 11
Initial action after AED analysis if the patient is in a shockable rhythm like VF/PVT
Correct Answer
Shock with 200J, and resume CPR

, Question 12
Class I - Sodium Channel Blockers
Correct Answer
•Blocks sodium influx through cell membranes
•Slows rate and amplitude of depolarization
•Reduces cell excitability
•Reduces conduction velocity



Question 13
Stimulation of β2 receptors causes:
Correct Answer
•β2- Dilates blood vessels and relaxes the airway.



Question 14
Atropine
Correct Answer
•Reverses cholinergic-mediated decreases in heart rate and should be a temporary
measure while awaiting transcutaneous pacemaker application.

•Atropine should first drug used for: Symptomatic bradycardia and in some AV
nodal heart blocks.

Note: Atropine should be avoided in patients with hypothermic bradycardia and
ischemic heart disease. Additionally atropine should be avoided in patients with 2nd
Degree Heart Block Type II and all 3rd degree Heart Blocks as these PTs require
immediate pacing.



Question 15
Dermis
Correct Answer
Tough and highly elastic layer of connective tissue
