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? Open a new HME and attach it to the endotracheal tube. A clean HME is required.

79-year-old patient with COPD shows signs of increasing anxiety & cyanosis while Receiving continuous heated aerosol therapy. patient complains of tightness in his Chest,frequent cough produces a small amount of pink,frothy sputum.patient most likely has pulmonary edema.These symptoms and signs are most consistent with pulmonary edema.

A shift supervisor wishes to determine the number of patients who are to receive bronchodilator treatments during the next 8 hours. To obtain this information quickly, the supervisor could review the assignment list from the last shift.

While reviewing a patient's chart, results of a chest radiograph indicate complete opacification of the left chest with a shift of the trachea and mediastinum to the left. These findings are consistent with atelectasis of the left lung.

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 prevent areas of the lung from collapsing.

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? helium/oxygen

A 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? paradoxical motion of the left chest.

When the respiratory therapist initiates an IPPB treatment, the patient's pulse is 78/min. Five minutes after the therapy is started, the patient's pulse increases to 90/min. The therapist should continue the treatment as ordered. The magnitude of the increase in pulse rate is not excessive for the treatment provided.

The respiratory therapist assesses a patient receiving supplemental oxygen by a transtracheal oxygen catheter. The patient is diaphoretic, has a higher than normal respiratory rate, and appears cyanotic. Which of the following is a possible explanation? The transtracheal catheter is obstructed by a mucous plug.

To assess an outcome indicator of the department's bronchodilator QA program, the respiratory therapist should monitor the average length-of-stay for patients receiving bronchodilators.

A 7-day-old neonate of 28-weeks gestational age is having frequent periods of apnea with desaturation. Which of the following should the respiratory therapist recommend? theophylline (Aminophylline)

A 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 Increase system flow. The reason for the negative pressure on the manometer is inadequate flow during inspiration. Increasing system flow would correct the problem.

During an interview, a patient with COPD who was recently admitted to the hospital tells the respiratory therapist that she does not want any heroic measures performed to lengthen her life. This information would best be documented in the advance directive. Documentation of a patient's desires regarding heroic measures should be specified in an advance directive. This can only be changed by the patient.
