Answers Already Graded A+
When properly placed, the distal tip of the LMA should sit where? - CORRECT
ANSWER-distal tip should sit at the cricopharyngeus muscle (right at the upper
esophageal sphincter)
Which antiemetics can prolong the QT interval and should be avoided in patients
with known Prolonged QT Syndrome? - CORRECT ANSWER-Avoid:
droperidol
ondansetron
decadron and scopolamine would be good to give these patients
Find the TV delivered to a patient when there is fresh gas flow coupling.
O2 flow= 2L/min
air flow= 1L/min
,set TV= 450 mL/min
RR= 10 breaths per min
I:E= 1:2 - CORRECT ANSWER-1. add the coupled flows together and change
from L to mL
2L/min + 1L/min = 3L/min = 3000 mL/min
2. multiply by the time spent in inspiration (1 sec I, 2 sec
E, total of 3 sec)
3000mL/min * 1/3 = 1000 mL/min
3. divide by RR
(1000 mL/min) / (10 breaths/min) = 100 mL/breath
4. add 100 mL to the set TV of 450 mL --> 550 mL
550 mL is the TV actually delivered
"Can't ventilate, can't intubate" scenario. What is the best way to secure the
airway? - CORRECT ANSWER-Requires an emergent surgical airway
a) surgical cricothyrotomy
,b) transtracheal jet ventilation
tracheostomy and retrograde intubation are not considered emergent airways
Convert Fahrenheit to Celsius - CORRECT ANSWER-F= (C x 1.8) + 32
What are the best oxygen sources for transtracheal ventilation? - CORRECT
ANSWER-High pressure O2 sources (TTJV requires psi of at least 25)
1. jet ventilator attached to anesthesia machine
2. O2 tank with a pressure regulator set to 50 psi
3. O2 flush valve on the anesthesia machine
Low pressure O2 sources (self resuscitation bag or reservoir bag on the anesthesia
machine) are not used for TTJV because they cannot fill the lungs with adequate
O2 flow
LA ranked from shortest DOA to longest DOA
a) procaine
b) lidocaine
, c) chloroprocaine
d) bupivacaine
e) mepivacaine
f) tetracaine
g) ropivacaine - CORRECT ANSWER-shortest (lowest protein binding) :
procaine, cholorprocaine (zero protein binding)
intermediate: lidocaine, mepivacine
longest (most protein binding): bupivacaine, ropivacaine, tetracaine
In a cirlce system, work of breathing is primarily determined by which component
of the system?
Think about Pouiselle's Law... - CORRECT ANSWER-Whatever answer choice
gives you the smallest diameter--> decreased radius/diameter increases
resistance
ETT is likely the answer since it has the narrowest diameter out of the Y piece,
unidirectional valves and circuit tubing
