-Guarantee passing score -39 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: Which of the following therapeutic gas mixtures should the respiratory therapist select to improve the distribution of ventilation for a patient with high airway resistance?

Answer:

helium/oxygen Question 2: To assess an outcome indicator of the department's bronchodilator QA program, the respiratory therapist should monitor the

Answer:

average length-of-stay for patients receiving bronchodilators.Question 3: Occlusion of the expiratory circuit just prior to the next ventilator delivered breath facilitates the measurement of

Answer:

auto-PEEP. Auto-PEEP is measured by subtracting set PEEP from the measured pressure during expiratory hold just prior to the next ventilator delivered breath.

Question 4: When a patient cannot increase minute ventilation, increasing mechanical dead space in the ventilator circuit will cause

Answer:

increased PaCO2.Increased mechanical dead space with a constant minute ventilation will increase PaCO2 by an increase in VD/VT.Question 5: patient receiving mechanical ventilation using PEEP switched continuous-flow CPAP system for weaning.On initial evaluation,manometer shows negative pressure during inspiration& patient appears agitated &uncomfortable.Which is most appropriate

Answer:

Increase system flow.The reason for the negative pressure on the manometer is inadequate flow during inspiration. Increasing system flow would correct the problem.Question 6: patient involved in motor vehicle crash presents with respiratory distress,chest radiograph confirms presence of multiple adjacent ribs fractured on the left side.Which of the following physical findings would be expected during palpation of the chest?

Answer:

paradoxical motion of the left chest Question 7: During the administration of an IPPB treatment, the respiratory therapist notices the system pressure drops after inspiration is initiated. Which of the following actions will best correct this problem?

Answer:

Increase the flow setting.Flow should be increased as tolerated until system pressure rises quickly and holds near the preset value.Question 8: Which of the following chest radiographs provide the best view of the lung apex, lingula, and right middle lobe?

Answer:

lordotic. The lordotic position provides the best view of the lung apex, lingula, and the right middle lobe.Question 9: During nasotracheal suctioning, the patient does not cough, but watery secretions are aspirated through the catheter. Which of the following should the respiratory therapist do next?

Answer:

Hyperextend the patient's neck when passing the catheter.

Question 10: A patient with chronic hypercapnia is receiving home oxygen therapy by nasal cannula at 2 L/min. The SpO2 is 90%. The patient should be told not to increase the flow because a higher oxygen flow

Answer:

may be dangerous.Excessive oxygen may lead to increased CO2 retention in patients who are hypercapneic.Question 11: When explaining the purpose of incentive spirometry to a patient after abdominal surgery, the respiratory therapist should tell the patient the procedure is performed to

Answer:

prevent areas of the lung from collapsing.Question 12: An unpackaged HME is found lying on top of a ventilator. No condensate is observed inside the HME. The patient has no other humidification device in place. Which of the following should the respiratory therapist do?

Answer:

Open a new HME and attach it to the endotracheal tube. A clean HME is required.Question 13: A patient with severe COPD is receiving oxygen by nasal cannula at 4 L/min. The patient is lethargic and his respirations are shallow at a rate of 20/min.The pulse oximeter is reading 94%. Which of the following should the respiratory therapist recommend?

Answer:

Change to a 28% air-entrainment mask.An air-entrainment system will deliver a controlled FIO2.Question 14: Which of the following would indicate a physical conditioning protocol has been effective for a patient with COPD?

Answer:

The patient has increased his level-walking distance by 15%. An important part of physical conditioning is an increase in exercise tolerance.Question 15: A patient is receiving 35% oxygen through an air-entrainment mask. Cool mist is being provided at the air-entrainment port. The FIO2 measured at the mask is 42%. Which of the following should the respiratory therapist do?

Answer:

Verify the integrity of the air-entrainment port. The determinants of FIO2 in this device are the jet size and the size of the entrainment ports. Any obstruction to the air-entrainment port will increase the FIO2 by decreasing the volume of air entrained.

Question 16: patient who is oxygen-dependent travels using oxygen from an E cylinder secured in back seat.He carries a spare cylinder in the trunk of his carwhen he plans to be out for longer periods of time.respiratory therapist should inform the patient he should

Answer:

secure the spare cylinder in the back seat.Question 17: A patient presents with sudden onset of dyspnea associated with cough, sputum production, and a chest radiograph demonstrating opacification of the right lower lobe. Which of the following is most consistent with these findings?

Answer:

asymmetrical chest movement Question 18: When performing quality control on an automated blood gas analyzer, the respiratory therapist notices the pH value is more than 2 standard deviations from the control group mean. The therapist should initially

Answer:

remeasure the reference sample.Question 19: The respiratory therapist is treating a patient with pulmonary emphysema. During the course of therapy, the patient becomes very dyspneic. The therapist should instruct the patient to perform

Answer:

pursed-lip breathing.Pursed-lip breathing may allow improved exhalation by stabilization of the airways.This maneuver should decrease dyspnea.Question 20: While assisting with a therapeutic bronchoscopy for an adult patient, the physician is suddenly unable to view any anatomy because everything went black. Which of the following is a likely cause?

Answer:

The light source is disconnected.Question 21: A patient requiring continuous oxygen at 3 L/min wants to maintain a very active lifestyle. Which of the following would be the best oxygen delivery system for the respiratory therapist to recommend?

Answer:

a liquid system. A liquid system is used for long-term continuous oxygen therapy. The portable units are light-weight, which makes the liquid system the choice for active patients.
