NBR C PRACTICE EXAM/ACTUAL EXAM QUESTIONS
WITH WELL DETAILED ANSWERS/GRADE A+
ASSURED
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. - (answers)B increqsing to 10 cmh2o peep
(The increase in peep will increase FRC, decrease the intrapulmonary shunt, and
address the hypoxemia)
When instructing a patient on the administration of unmeclidinium/vilanterol
(anoro Elliot's), which of the following is most important to emphasize?
A. Gargle immediately after use
B. Inhale slowly with a breath hold.
C. Breathe in fast and deep
D. Shake medication vigorously before use - (answers)C. Breathe in fast and deep
(This is a DPI)
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 - (answers)D. Semi fowlers
(Decreased incident of VAP has been observed with an elevated head of bed
compared to supine)
Which of the following is used to monitor the partial pressure of transcutaneous
carbon dioxide?
A. Red-light absorption sensor
B. Electromechanical transducer
C. Infrared analyzer
D. Stow-severinghaus electrode - (answers)D. Stow-Severinghaus electrode
(A stow-severinghaus electrode blood has electrode is used in transcutaneous
monitors)
An adult patient requires frequent blood sampling and medication
administrations 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 - (answers)A. Peripherally inserted central catheter
(A PICC is the best choice for long term iv access and allows for blood sampling)
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
Which of the following is most appropriate?
A.
Decrease the FIO2 to 0.60.
B.
Change the PEEP to 5 cm H2O.
C.
