PO2 70 mm Hg
HO3 25 mEq/L
BE -4 mEq/L
SO2 (calc) 94%
A respiratory therapist should recommend increasing the
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 CT scan with contrast could identify a pulmonary embolus or fluid collection, but this would not be the most appropriate next step in evaluating this patient.)
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

SO2 (calc) 83%
A respiratory therapist should FIRST
A. sedate the patient.
B. intubate the patient.
C. administer 2.5 mg albuterol.
D. switch to nonrebreathing mask - CORRECT_ANSWER_D. switch to nonrebreathing mask
A nonrebreathing mask will provide a higher FIO2 than the air-entrainment mask.
Following placement of a subclavian venous catheter, the high pressure alarm on a patient's ventilator begins sounding. After 10 minutes, the patient's peak inspiratory pressure has increased from 40 to 60 cm H2O and mean arterial pressure decreased from 80 to 40 mm Hg. A respiratory therapist should FIRST
A. increase the peak flow.
B. suggest administering a vasopressor.
C. suction the endotracheal tube.
D. recommend needle decompression. - CORRECT_ANSWER_D. recommend needle decompression.
Tension pneumothorax is a possible complication of venous catheter insertion and can result in increased airway pressure. This would sound the high pressure alarm and decrease arterial pressure. Needle decompression is indicated.
While counseling a patient during a smoking cessation session, the patient expresses concern about weight gain. A respiratory therapist should address the patient's concern by explaining that this is partially the result of
A. decreased metabolism.
B. increased loss of self-control.
C. reliance on nicotine replacement therapy.
D. lack of available aversive conditioning. - CORRECT_ANSWER_A. decreased metabolism.
