NCLEX MECHANICAL VENTILATION TEST
BANK EXAMS SET EXAM FULL QUESTIONS
AND CORRECT ANSWERS 2026 100%
CORRECT.
⩥ True controlled ventilation Answer: Time- triggered breaths
Only appropriate when patient cannot make voluntary effort
Sedated
Patient cannot trigger
⩥ Problem that may arise with patient triggered breaths Answer:
Hyperventilation
⩥ Volume controlled CMV (A/C) Answer: *Pressure waveform
should NOT be concave - if so its to meeting flow needs of patient
(graph)
⩥ Pressure controlled CMV "PC-CMV or AC-CMV" Answer: Time
or patient triggered
Pressure is targeted to rate needs to be set to limit time
⩥ High pressure alarms Answer: Set to 10-15 cmH2O above set IPAP
within CMV "AC"
,⩥ What can cause transient circuit pressure increases? Answer:
Coughing, mucous plunging, blockage of tube (biting) - suction
⩥ How can vents manage excess pressure in circuit? Answer: Breath
will stop, excess pressure will exit through exhalations valve
⩥ IMV "SIMV" Answer: Time triggered
Pressure or volume controlled
*add pressure support to add volume to spontaneous breaths
⩥ SIMV PVS flow graph Answer: Decelerating - time cycled
⩥ 3 means of providing support for spontaneously breathing patient
Answer: 1. Spontaneous breathing
2. CPAP
3. PSV < 6 bpm
⩥ Pressure Support Ventilation (PSV) Answer: mode of mechanical
ventilation in which preset positive pressure is delivered with
spontaneous breaths to decrease work of breathing
Provides constant pressure during inspiration —- to enhance tidal
volume!
***all PSV breaths are patient triggered, pressure limited, and FLOW
cycled
, ⩥ Appropriate ___ delivery is key to successful PSV Answer: Flow
⩥ Flow is also known as Answer: "rise time"
⩥ BiPAP Answer: Flow or time cycled
⩥ PRVS pressure regulated volume control Answer: Patient or time
triggered
Volume targeted
TIME cycled
***vent measures delivered tidal volume and compares to set tidal
volume, if delivered is less than set VT then vent will gradually
increase pressure (***by no more than 3cmH2O)
If pressure is too high then vent will not let it rise higher than
***5cmH2O below the high pressure Iimit
⩥ APRV (airway pressure release ventilation) Answer: Provides 2
levels of CPAP
Used in patients with stiff lungs - ARDS
⩥ A patient breathes spontaneously at a baseline pressure of +8 cm
H2O. This pressure remains
at +8 cm H2O throughout inspiration and exhalation. What mode is
being described? Answer: CPAP (or continuous spontaneous
ventilation)
