Practice exam B NBRC
1. A patient with a PBW of 55 kg (121 lb) is receiving VC,
A/C ventilation. Ventilator settings and blood gas analysis
results are:
FIO2 0.70
Mandatory rate 14
VT 350 mL
PEEP 5 cm
H2O
pH 7.35
PaCO2 35 mm
Hg PaO2 40
mm Hg HCO3-
19 mEq/L
BE -6 mEq/L
SO2 (calc) 74%
A respiratory therapist should
recommend A.
changing to SIMV
mode. B.
increasing to 10 cm H2O
PEEP. C.
,changing to 5 cm H2O
CPAP. D.
increasing to 400 mL VT.: ANS B increqsing to 10 cmh2o peep
(The increase in peep will increase FRC, decrease the intrapulmonary
shunt, and address the hypoxemia)
2. When instructing a patient on the administration of
unmeclidinium/vi- lanterol (anoro Elliot's), which of the
following is most important to empha- size?
A. Gargle immediately after use
B. Inhale slowly with a breath hold.
C. Breathe in fast and deep
D. Shake medication vigorously before use: ANS C. Breathe
in fast and deep (This is a DPI)
3. Following placement of a tracheostomy tube for long term
mechanical ventilation, which of the following patient
positions best prevents ventilator
,associated pneumonia?
A. Prone
B. Trendelenburg
C. Supine
D. Semi-fowlers: ANS D. Semi fowlers
(Decreased incident of VAP has been observed with an elevated
head of bed compared to supine)
4. Which of the following is used to monitor the partial
pressure of transcu- taneous carbon dioxide?
A. Red-light absorption sensor
B. Electromechanical transducer
C. Infrared analyzer
D. Stow-severinghaus electrode: ANS D. Stow-Severinghaus
electrode
(A stow-severinghaus electrode blood has electrode is used in
transcutaneous monitors)
5. An adult patient requires frequent blood sampling and
medication admin- istrations through an iv for 1 month: the
preferred vascular access is a:
A. Peripherally inserted central catheter
B. Subclavian central vascular line
C. Standard peripheral IV line
D. Internal jugular catheter: ANS A. Peripherally inserted central
catheter
, (A PICC is the best choice for long term iv access and allows for blood
sampling)
6. A 170-cm (5-ft 7-in), 69-kg (152-lb) male with ARDS has the
following ABG analysis results:
pH 7.37
PCO2 43 mm
Hg PO2 95
mm Hg
HCO3- 25
mEq/L
BE -1 mEq/L
SO2 (calc) 97%
The patient is receiving VC, A/C ventilation with the
following settings: FIO2 0.70
Mandatory rate 12
VT 450 mL
PEEP 8 cm
H2O
