Prior to suctioning the endotracheal tube of an adult patient who is receiving
ventilation with an FIO2 of 0.40, a respiratory therapist should FIRST
A. lubricate the catheter.
B. hyperoxygenate the patient.
C. cleanse the catheter with water.
D. administer an FIO2 of 0.40 by T-piece. –
A+ TEST BANK 1
, NBRC / TMC / RRT Exam 2025
Correct Answer :B. hyperoxygenate the patient.
The FIO2 should be increased prior to each suctioning attempt to minimize
hypoxemia.
A 25-year-old patient with apnea is receiving PC ventilation. ABG analysis results
are as follows:
pH 7.20
PCO2 65 mm Hg
PO2 70 mm Hg
HCO3- 25 mEq/L
BE -4 mEq/L
SO2 (calc) 94%
A respiratory therapist should recommend increasing the?
A. set inspiratory pressure.
B. expiratory time.
C. sensitivity.
D. peak flow. –
Correct Answer :A. set inspiratory pressure.
A+ TEST BANK 2
, NBRC / TMC / RRT Exam 2025
In PC ventilation, increasing the inspiratory pressure will result in an increased
tidal volume and minute ventilation, potentially causing a decrease in the PCO2.
A 68-year-old patient who is post-CABG was extubated 4 hours ago and
complains of increasing shortness of breath. Breath sounds are decreased over
the right lung field. The following data are available while the patient receives 4-
L oxygen by nasal cannula:
HR 103/min
RR 27/min
BP 155/90 mm Hg
SpO2 90%
Which of the following studies should a respiratory therapist recommend FIRST?
A. bedside spirometry
B. chest CT with contrast
C. ventilation/perfusion scan
D. chest radiograph –
Correct Answer :D. chest radiograph
Based on the timing and symptoms, the dyspnea could be due to
pneumothorax, chest tube malfunction, lobar collapse, or accumulation of
pleural fluid. A chest radiograph can be obtained quickly to identify the issue for
rapid intervention.
A+ TEST BANK 3
, NBRC / TMC / RRT Exam 2025
Which of the following medications should a respiratory therapist use to
anesthetize a patient's airway prior to a flexible bronchoscopy procedure?
A. lidocaine HCl
B. midazolam HCl (Versed)
C. ketamine (Ketalar)
D. vecuronium bromide (Norcuron) –
Correct Answer :A. lidocaine HCl
Lidocaine HCl is a topical anesthetic and will reduce airway reflexes during the
procedure.
A respiratory therapist is evaluating a 75-kg (165-lb), 180-cm (5-ft 11-in) male who
is receiving VC, SIMV. The following patient data are obtained:
FIO2 0.40
Mandatory rate 8
Total rate 8
VT 550 mL
PEEP 8 cm H2O
pH 7.27
PaCO2 55 mm Hg
