. A patient who requires mechanical ventilation has her PEEP increased from 10 to
15 cm H2 O. Within 20 minutes,her blood pressure has decreased, and her heart
rate has increased. What should be recommended?
A. Increase the O2 percentage.
B. Increase the patient's intravenous fluids.
C. Remove the PEEP completely.
D. Decrease the PEEP back to 10 cm H 2 O.
D. Decrease the PEEP back to 10 cm H 2 O.
D. (c) Decreasing the PEEP to the previous level should result in the patient's vital
signs returning to normal.

141. About how many hours will an H-cylinder of O 2 last if it has 1100 psig and is
emptying at a flow of 8 L/min?
A. 2
B. 5
C. 7
D. 9
C. 7
duration = (gauge pressure x cylider factor)/flow
= (1100psig x 3.14)/8 L/min
= 7.2 0r 7
A mechanically ventilated patient has atelectasis and a small functional residual
capacity (FRC). This has caused hypoxemia. What would you recommend to help
correct the atelectasis and small FRC?
A. Add PEEP.
B. Increase the O2 percentage.
C. Suction the patient more frequently.
D. Start PSV.
A. Add PEEP.
A. (c) Therapeutic PEEP on the ventilator will increase the FRC and the patient's O 2
level and should help to correct
the atelectasis.
A 47-year-old patient tells the respiratory therapist that over the past 3 years he
has developed a productive cough from December through March. This finding
would suggest that he has
A. Laryngotracheobronchitis.

B. Cystic fibrosis.
C. Chronic bronchitis.
D. Asthma.
C. Chronic bronchitis.
C. (c) Chronic bronchitis is confirmed by a productive cough that lasts for at least 3
months over at least a 3-year
period.
. A patient with COPD is being ventilated on a VC, SIMV mode. Wheezing is present
in all lung fields. The peak pressure is 47 cm H2O and plateau pressure is 10 cm
H2O with a set V T of 550 mL and a flow of 40 L/min. What should the respiratory
therapist recommend?
A. Change to nasal CPAP at 10 cm H2O pressure
B. Increase the flow to 60 L/min.
C. Nebulize ipratropium bromide and albuterol (Combivent Respimat).
D. Change to pressure support mode at 47 cm H 2 O pressure.
C. Nebulize ipratropium bromide and albuterol (Combivent Respimat).
C. (c) The combination of these two bronchodilating medications has been shown
to effectively reverse bronchospasm
and reduce airway resistance in COPD patients.
A respiratory therapist is working with a patient who was rescued from a house
fire. A pulse oximetry probe attached to his finger shows an SpO 2 reading of 99%.
An arterial blood gas sample drawn with the patient wearing a nonrebreathing
mask has been analyzed through a CO-oximeter. The results show a PaO2 of 130
mm Hg, PaCO2 of 30 mm Hg, and SaO2 of 75%. What would best explain the
differences in saturation?
A. CO-oximeter is out of calibration.
B. Increased level of COHb
A+ TEST BANK 3
, NBRC / TMC / RRT Exam 2025
C. Pulse oximeter sensor has been incorrectly placed.
D. The patient's skin is darkly pigmented.
B. Increased level of COHb
B. (c) A standard pulse oximeter cannot identify COHb as dysfunctional
hemoglobin. A CO-oximeter will accurately
measure a high plasma PaO 2 and low SaO 2 as is usually seen in a patient with
carbon monoxide poisoning.
An adult patient is being maintained on a volume-cycled ventilator. After
endotracheal suctioning is performed, which of the following would show that
airway resistance has decreased?
A. Lower peak pressure
B. Larger V T
C. Lower plateau pressure
D. Decreased inspiratory time
A. Lower peak pressure
A. (c) A lower peak pressure would show that airway resistance has decreased
after secretions have been suctioned
out.
A 40-year-old comatose man is found to have a respiratory rate that varies from 8
to 40 per minute with random apnea periods. Bedside spirometry shows his tidal
volume to range between 200 mL and 1300 mL, with each breath being different.
His breathing pattern would best be described as
A. Kussmaul's respiration.
B. Biot's respiration.
C. Cheyne-Stokes respiration.
D. Partially obstructed upper airway.
B. Biot’s respiration.
