Prior to taking a pulmonary artery wedge pressure (PCWP) reading, the RT ensure that: correct answer: -the transducer is properly leveled and zeroed The fiberoptic bronchoscope is usually preferred device during bronchoscopy b/c its: correct answer: -flexibility The capnograph tracing above was obtained from a mechanically ventilated pt. On the basis of this tracing, the RT should: correct answer: -check the exhalation valve A RT is performing nasotracheal suctioning. During the proc...

A respiratory therapist is assisting a physician during a transtracheal bronchoscopy. As the bronchoscope is advanced in the airways, the above ECG tracing is observed on the patient's cardiac monitor. The RT should recommend? correct answer: Administration of lidocaine. After extubating a patient the RT observes the onset of inspiratory stridor. After administering racemic epinephrine (vaponefrin), the patient still has inspiratory stridor, but a lesser extent. The therapist should now do ...

The physician orders a 35% aerosol mask to be set up for a patient who requires an inspiratory flow of 42 L/min. What is the minimum flow rate to which the flowmeter must be set to meet this patient's inspiratory flow demands? A. 6L/min B. 8L/min C. 10L/min D. 12L/min correct answer: *B*, The air/O2 ratio for a 35% oxygen mixture is 5 : 1. To calculate total flow output from this device, add the ratio parts together and multiply by the liter flow: 6 × 6 = 36 L/min, 6 × 8 = 48 L/min, 6 ...

A patient on VC ventilation demonstrates auto-PEEP on ventilator graphics. Which of the following controls, when adjusted independently, would increase expiratory time? 1. Tidal volume 2. Respiratory Rate 3. Inspiratory flow 4. Sensitivity correct answer: *A. 1, 2, and 3 only B. 1, 2, and 4 only C. 1, 3, and 4 only D. 2, 3, and 4 only Which of the following would be the most appropriate therapy for a dyspneic patient who has crepitus with tracheal deviation to the left and absen...

A 36 weeks gestation, 4 hour post-delivery neonate has the following ABG results while on a 35% oxyhood: pH: 7.34 PaCO2: 47 mmHg PaO2: 57 mmHg HCO3: 25 mmHg The RT should recommend: correct answer: Maintain current therapy and continue to monitor A pt with AIDS is to be given treatment for the prevention of Pneumocystis carinii pneumonia. Which of the following is most appropriate therapy for this pt? correct answer: Pentamidine (NebuPent) via Respigard once every 4 weeks An intubat...

What formula is used to determine cardiac output? correct answer: Fick Equation What is the normal range for cardiac output? correct answer: 4-8 LPM What are the units that measure cardiac index? correct answer: L/min/m^2 (cardiac index = cardiac output / body surface area) [body surface area for most patients is about 2 m^2] What is the normal range for cardiac index? correct answer: 2-4 L/min/m^2 If a patient is bleeding during bronchoscopy, you would administer _______________...

The physician orders a 35% aerosol mask to be set up for a patient who requires an inspiratory flow of 42 L/min. What is the minimum flow rate to which the flowmeter must be set to meet this patient's inspiratory flow demands? correct answer: 8 L/min A premature infant is receiving O2 via a 50% O2 hood and has a PaO2 of 43 torr and a PaCO2 of 40 torr. The respiratory therapist should recommend what? correct answer: Initiate CPAP a 4 cm H2O and 50% O2 A patient arrives in the emergency d...

A patient with a history of chronic bronchitis is post-operative for an exploratory laparotomy. Review of the medical record suggests the physician has concern about difficulty clearing secretions after the procedure. To assist the patient with mobilization and removal of secretions, the respiratory therapist should recommend a. MDI therapy with an anti-inflammatory corticosteroid b. Administer tetracycline c. Administer cromolyn sodium d. Instruction on deep breathing and coughing technique...

A 43-year-old male patient was admitted to the emergency department with a suspected drug overdose. The patient is receiving oxygen via nonrebreather but is unconscious and isn't making any respiratory efforts to breathe. The patient's body weight is 57 kg and his ABG results are as follows: pH 7.28 PaCO2 74 torr HCO3 20 mEq/L PaO2 315 torr Which of the following would you recommend? A. Apply BiPAP with: IPAP 20 cm H2O, EPAP 5 cm H2O, FiO2 30% B. Intubate and apply: SIMV, tidal volume 600...
