Which of the following studies should a respiratory therapist recommend

FIRST?

• bedside spirometry
• chest CT with contrast
• ventilation/perfusion scan
• 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 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?

• lidocaine HCl
• midazolam HCl (Versed) 1 / 4

• | P a g e

pg. 2

• ketamine (Ketalar)
• 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 PaO2 94 mm Hg HCO3 - 25 mEq/L BE -3 mEq/L SaO2 (calc) 97%

Which of the following should the therapist recommend?

• Maintain current settings.
• Increase the mandatory rate to 12.
• Decrease the FIO2 to 0.30. 2 / 4

• | P a g e

pg. 3

• Decrease the tidal volume to 450 mL. - Correct Answer - B. Increase

the mandatory rate to 12.Increasing the mandatory rate will increase the V̇E. This should correct the respiratory acidosis.

A 63-year-old patient with COPD is seen in the pulmonary clinic for a routine appointment. The analysis results of an ABG sample drawn

while the patient is breathing air are:

pH 7.40 PCO2 57 mm Hg PO2 42 mm Hg HCO3 - 35 mEq/L BE +8 mEq/L SO2 (calc) 77%

Which of the following is the most appropriate NEXT step?

• Schedule polysomnography.
• Initiate supplemental oxygen.
• Perform a 6-minute walk test.
• Coach on deep breathing. - Correct Answer - B. Initiate supplemental

oxygen.Administering oxygen and observing the patient is the appropriate therapy for a hypoxemic patient with COPD, as indicated by the ABG analysis.

pg. 4 A pulse oximeter can provide an accurate indication of a patient's oxyhemoglobin saturation in which of the following clinical conditions?

• congestive heart failure
• polycythemia
• pulmonary hypertension
• carbon monoxide poisoning

• 1, 2, and 3 only
• 2, 3, and 4 only
• 1, 2, and 4 only
• 1, 3, and 4 only - Correct Answer - A. 1, 2, and 3 only

Carbon monoxide poisoning will result in carboxyhemoglobin. Standard pulse oximetry is unable to distinguish oxyhemoglobin from carboxyhemoglobin, which will lead to a falsely elevated SpO2 reading.

A patient receiving mechanical ventilation by a portable ventilator is being transported from the ED to radiology. Which of the following is required during transport?

• bag-valve mask resuscitator
• point-of-care blood gas analyzer
• demand valve respirator
• crash cart - Correct Answer - A. bag-valve mask resuscitator
• A bag-valve mask resuscitator is required in case of transport

ventilator failure.
