NUR 431L (AIRWAY) FINAL EXAM
QUESTIONS AND ANSWERS
10 breaths per minute - Answer-What is the proper ventilation rate for a patient in
cardiac arrest who has an advanced airway in place?
Pressure Support Ventilation (PSV) - Answer-Which of the following is a pressure-
targeted ventilator mode?
Synchronized Intermittent Mandatory Ventilation (SIMV) - Answer-Which of the following
is a volume-targeted ventilator mode?
1 breath every 5-6 seconds - Answer-What is the appropriate ventilation strategy for an
adult in respiratory arrest with a pulse rate of 80/minute?
High pressure - Answer-Which of the following alarm problems is caused by a blocked
or kinked ET?
-Circuit disconnect (Lewis)
-Coughing secretions building up, biting ET: high pressure - Answer-Which of the
following is a likely cause of a low-pressure alarm?
Plateau pressure - Answer--meaning there is no flow at the end of inspiration; measures
by pausing for a second right after inspiration
-the button on the machine is called the inspiratory pause
-this pressure should ALWAYS be lower than your peak inspiratory pressure
-if higher, repeat the maneuver
Airway resistance - Answer--can be manufactured or artificial airway;
-always choose the largest artificial airway that you can that will fit in pt comfortably bc it
minimizes the WOB that pt has to overcome, easier to breathe through, and less likely
to develop any type of mucus plugs
-change in pressure over flow
-will look at PIP, plateau pressure and divide it by our inspiratory flow in L per second -
Answer-Formula for airway resistance=
Signs of cardiovascular insufficiency because pressure in the chest impedes venous
return - Answer-The nurse monitors the patient with positive pressure mechanical
ventilation for:
Lung compliance - Answer-tells us how easy it is for pt to breath and relax; we can
measure this on a mechanical ventilator
