RN 402 EXAM 1 2026/2027 | NURSING STUDY GUIDE, PRACTICE QUESTIONS,
ANSWERS & EXAM REVIEW
CPAP (continuous positive airway pressure) - correct answer ✔✔Restores functional residual capacity
Similar to PEEP - pressure delivered continuously during spontaneous breaths
Increases WOB - pt must forcibly exhale against CPAP
*caution in pt with myocardial compromise
BiPAP (bilevel positive airway pressure) - correct answer ✔✔delivers different inspiratory and expiratory
pressures depending on patient needs
Pt must be able to breathe spontaneously
Contraindicated in pts with increased secretions or AMS
ET intubation - correct answer ✔✔Preoxygenate 3-5 min before
Limit each attempt less than 30 seconds
Monitor oxygen status
Inflate cuff and confirm placement - 2 to 6 cm above carina
Record and mark position, obtain ABGs, monitor O2 and CO2
Nursing management - ET tube - correct answer ✔✔Monitor placement - symmetrical chest wall
expansion, breath sounds
Cuff seal - 20 to 25 cm H2O
Monitor oxygenation - SPo2, ABGs, SVo2, hypoxemia SS
Monitor ventilation - PACO2, Resp rate and rhythm, accessory muscles
Maintain tube - no routine suction, assess needs to suctioning, open vs closed suction
Unplanned extubation signs - correct answer ✔✔Activation of low pressure alarm
Diminished or absent breath sounds
Respiratory distress
Auditory cuff leak
Mechanical ventilation - correct answer ✔✔The process by which the fraction of inspired oxygen
concentration (FIO2) is at 21% (room air) or greater and is moved in and out of the lungs by a mechanical
ventilation.
Negative pressure ventilation - correct answer ✔✔use of chambers that encase the chest or body and
surround it with intermittent negative pressure
Negative pressure "pulls" chest outward, causing air to rush in - passive expiration
Noninvasive and does not require artificial airway
Positive pressure ventilation - correct answer ✔✔Pushes air into the lungs under positive pressure
during inspiration
Volume ventilation - predetermined tidal volume delivered with each inspiration
Pressure ventilation - predetermined peak inspiratory pressure, careful attention need to prevent
hypo/hyperventilation
