NRNP6665 PREPARATION TEST 2026
QUESTIONS AND CORRECT ANSWERS
GRADED A+
● respiratory aklalosis. Answer: pH> 7.45, PaC02 low, HC03 low
● respiratory acidosis. Answer: pH < 7.35
PaCO2 > 45
Hc03 normal 22-26
● Metabolic alkalosis. Answer: pH > 7.45
HCO3 > 26
PaC02 45-35
● normal oxygen levle. Answer: 80-100
● mild hypoxemia. Answer: 60-80
● moderate hypoxemia. Answer: 40-60
● severe hypoxemia. Answer: <40
,● A-a gradiatian calculation is a calculation of what?. Answer: level of
hypoxia
PA02-Pa02
● A-a gradiant varies with age, calculation. Answer: 2.5 + 0.21 x age in
years
● 5 causes of hypoxemia. Answer: VQ mismatch
shunt
PNA, interstitial lung dz
hypoventilation
high altitude
● clinical symptoms that require intubation. Answer: neuromuscular
depression or failure.
spinal cord injuries
guillain barre syndrome
trauma-spinal cord injuries, phrenic nerve injury
myasthenia gravis
shock
status asthmaticus
sustained apnea of any kind
, ● indications for weaning from vent. Answer: underlying process that
required the vent is corrected
maintaining oxygen status
no presser support- levophed, epinephrine, etc.
Pa02 >80, FI02 of 0.5, and PEEP <8.0 cm H20
● prior to seperation from the vent proceed with this ...... to determine if
pt is able to dc vent. Answer: trial of spontaneous breathing
● Volume targeted assist control (AC) mode. Answer: the clinician
determines tidal volume and rate/ pt can still breath over the vent.
example: pt gets RR of 12 but has an additional 2 breaths on their own,
pt will still breathe 14 breaths/min. tidal volume is based on the vent.
● Synchronized intermittent mandatory ventilation SIMV. Answer:
clinician sets rate, and tidal volume, and peak inflation pt can also have
their own breaths. tidal volume is set based on the patient. VENT doesn't
specify tidal volume.
● Pressure Control. Answer: A mode of ventilation that is normally
patient or time triggered, pressure targeted and time cycled.
● AC control vent settings how do you determine tidal volume?.
Answer: is based on ideal body weight. careful with obese patients.
