What is normal urine output in an adult patient? - ANSWER - 40 mL/hr

The following ABG results are reported for a patient in the ED on room

air: pH 7.20; PaCO2 24 torr; PaO2 95 torr; HCO3 8 mEq/L; SaO2 95%;

BE -15 mEq/L. The respiratory therapist should recommend

• initiating oxygen therapy via nasal cannula at 4 L/min.
• intubating and initiating mechanical ventilation.
• administering sodium bicarbonate intravenously.
• initiating non-invasive ventilation. - Correct Answer - administering

sodium bicarbonate intravenously.

The physician asks the respiratory therapist to set ventilator parameters that will deliver the lowest peak inspiratory pressure possible. Which of the following inspiratory flow patterns will enable the therapist to fulfill the physician's request?

• Decelerating
• Square wave
• Constant
• Accelerating - Correct Answer - Decelerating 1 / 4

pg. 2 An intubated patient receiving 30% oxygen has a SpO2 of 80% and ETCO2 of 40 torr. After administration of 50% oxygen for 30 minutes, the respiratory therapist notes that the SpO2 rises to 98% and the ETCO2 remains stable at 40 torr. The major cause of hypoxemia in this patient is

• hypoventilation.
• shunt.
• ventilation/perfusion mismatch.
• increased deadspace. - Correct Answer - ventilation/perfusion

mismatch.

A 16 year-old patient with cystic fibrosis attends public high school.Which of the following bronchial hygiene therapies would be most appropriate for this patient?

• intrapulmonary percussive ventilation
• dornase alpha therapy
• vibratory / oscillatory PEP
• postural drainage and manual percussion - Correct Answer - vibratory

/ oscillatory PEP

A patient reports that he has difficulty breathing while lying in a supine position and prefers to sleep sitting in a chair. The respiratory therapist should record this complaint in the medical record as

• orthopnea.
• platypnea.
• eupnea. 2 / 4

• | P a g e

pg. 3

• Kussmaul breathing. - Correct Answer - orthopnea.

A home care patient calls in the middle of the night and reports that the oxygen supply tubing will not stay attached to her transtracheal catheter.The flow rate to the transtracheal catheter is set at 0.5 L/min. The patient has attempted to flush the catheter with saline and push a cleaning rod through it without success. The respiratory therapist should instruct the patient to

• tape the connection securely.
• increase the flow to the catheter.
• decrease the flow to the catheter.
• switch to a nasal cannula. - Correct Answer - switch to a nasal

cannula.

A patient with copious amounts of secretions has required nasotracheal suctioning for the past 36 hours and has now developed mild epistaxis.Which of the following should the respiratory therapist recommend?

• Insert a laryngeal mask airway (LMA) to facilitate suctioning.
• Discontinue nasotracheal suctioning for 24 hours and reassess the

patient.

• Insert a nasopharyngeal airway after bleeding has been controlled.
• Insert an oral endotracheal tube to allow for better airway access. -

Correct Answer - Insert a nasopharyngeal airway after bleeding has been controlled.

The most probable cause of air bronchograms and increased density on a chest x-ray is 3 / 4

• | P a g e

pg. 4

• pneumonia.
• pulmonary edema.
• pulmonary embolism.
• pleural effusion. - Correct Answer - pneumonia.

A post-operative patient is receiving mechanical ventilation in the ICU

at the following settings: VC, A/C; VT 550 mL, respiratory rate 14/min,

FIO2 0.50 and 10 cm H2O PEEP. Bedside monitoring results demonstrate that the PvO2 is 35 mm Hg and the SpO2 is 90%. The patient is alert and oriented with stable vital signs. Which of the following should the respiratory therapist recommend?

• Decrease the PEEP.
• Increase the FIO2.
• Initiation diuretic therapy.
• Continue to monitor closely. - Correct Answer - Increase the FIO2.

Which of the following findings is LEAST compatible with hyperlucency as seen on a chest x-ray?

• Increased fremitus
• Decreased intensity of breath sounds
• Diminished diaphragmatic excursion
• Hyperresonance to percussion - Correct Answer - Increased fremitus

A spontaneous breathing trial was initiated on an intubated, awake, and alert 70 kg (154 lb) patient. After 30 minutes on an FIO2 of 0.30, ABG
