-long-latency
-short-latency
-beta wave
-alpha wave

short latency

Question 6

-carboxyhemoglobin
-oxyhemoglobin
-reduced hemoglobin
-methemoglobin

Answer 6

-carboxyhemoglobin

Question 7

Physiologic effects of hypocarbia? (Capnography | slide 4)
-blunting of respiratory drive and decreased cerebral blood flow
-blunting of respiratory drive and respiratory acidosis
-respiratory alkalosis and potassium shift to intravascular space
-respiratory alkalosis and increased ICP

Answer 7

-blunting of respiratory drive and decreased cerebral blood flow

Question 8

End-tidal CO2 is typically measured at the end point of which phase?
-phase I
-phase IV
-phase III
-phase 0
-phase II

Answer 8

phase III

Question 9

The capnogram has a prolonged upstroke with an alpha angle of >110 degrees, what is the problem causing this change?
-the ETT is partially obstructed
-the heart is beating in close proximity to the heart
-the waveform is normal
-spontaneous ventilation is occurring

Answer 9

-the ETT is partially obstructed

Question 10

10. What are the causes of decreased ETCO2? (SELECT 2)
    -seizures
    -hypoventilation
    -hypothermia
    -poor gas sampling

Answer 10

-hypothermia
-poor gas sampling

Question 11

11. The cause of this end-tidal capnogram is due to:
    -circuit leak
    -exhausted absorbent
    -hyperventilation
    -obstructed ETT

Answer 11

• exhausted absorbent
• RATIONALE: If the inspiratory baseline is elevated and carbon dioxide is greater than zero, CO2is being rebreathed
  differential diagnosis includes anincompetent expiratory valve, exhausted CO2absorbent, gas channeling through the absorbent, or an imperfectly calibrated capnometer.

Question 12

The fast-flush test of an arterial line is a method that determines:
-transducer leveling
-assessment of the vascular tree
-changes in conduction system
-system dynamic response

Answer 12

• system dynamic response
  RATIONALE: Thefast-flush test provides a convenient bedside method for determining system dynamic response and assessing signal distortion.

Question 13

Which method of heart transfer results in a loss of heat to air immediately surrounding the body?
-evaporation
-radiation
-convection
-conduction

Answer 13

convection
