ANSWERPleural Effusion
A patient is being monitored with a pulmonary artery catheter. The following
measurements are recorded:
CVP: 4 mmHg
Mean PAP: 18 mmHg
MAP: 84 mmHg
Cardiac Output: 4 L/min
What is the patient's systemic vascular resistance? - ANSWER(MAP-CVP) / Cardiac
Output
(84 - 4) / 4
80/4 = 20
Convert to dynes: multiply answer by 80
20 x 80 = 1,600 dynes/s/cm

ANSWER22 mmHg
Which suction catheter would be most appropriate to use for a patient with a size
7.5 mm ID ETT? - ANSWER(ID size / 2) x 3
7.5/2= 3.75 x 3 = 11.25
Round down to 10 Fr

the mask against the patient's face
What value for oxygenation index would indicate the need for ECMO in a newborn? -
ANSWER44
, A 44-year-old male has been admitted to the hospital after being involved in a sky
diving accident. He is 193 cm (6ft 4 in) tall and weighs 82 kg (182 lbs). The patient has
been orally intubated with a size 8.5 ETT. A CXR reveals bilateral opacification of all
lung fields. Mechanical ventilation has been established with a volume ventilator at
the following settings:
Mode: VC, SIMV
Vt: 650 mL
RR: 12/min
FiO2: 0.65
PEEP: 10
PIP: 58
Plat: 50
ABG: pH 7.30, PaCO2 43, PaO2 45, HCO3 21, SaO2 82%
The patient's condition is most likely related to: - ANSWERVenous admixture
Estimate the shunt fraction for a patient with the following available data:
A-aDO2: 200 torr
C(a-v)O2: 3.6 vol%
P/F Ratio: 400 torr - ANSWERFor each 100 mmHg in A-a, a 5% shunt occurs. Add 5%
more to that answer (due to normal shunting).
200 torr = 10% + 5% = 15% shunt
An 80kg (176 lb) patient in the post-anesthesia care unit following lower abdominal
surgery is receiving mechanical ventilation. Ventilator settings are as follows:
VC, SIMV
Vt: 550 mL
f: 15/min
FiO2: 70%
PEEP: 15
ABG: pH 7.35, PaCO2 44 torr, PaO2 85 torr, HCO3 23, SaO2 99%, C(a-v)O2 10 vol%
The RT should: - ANSWERReduce the PEEP setting.
In preparation for assisting a pulmonologist with a fiberoptic bronchoscopy for a 50-
year-old woman receiving mechanical ventilation, the RT notices that the patient
appears to be anxious about undergoing the procedure. The therapist should
recommend administration of: - ANSWERMidaxolam
The parameter that starts the inspiratory phase of a positive pressure breath is
referred to as the - ANSWERtrigger variable
While evaluating a patient receiving mechanical ventilation, the RT observes a
persistent high pressure alarm. What could cause that situation? - ANSWERExcessive
secretions
What would be the most appropriate initial ventilator settings for a patient recently
intubated for myasthenia gravis? The patient is 178cm (5'10") and weighs 70 kg.
A. PC, SIMV; PIP 50 cm H2O, f 8/min, FiO2 .50, PEEP 2
