A 3-year-old is brought to the emergency department via ambulance after the parents called 911 when they noticed their child’s behavior changed and his tongue began to swell. Based on the table below, what is the nurse’s 2 priority actions to anticipate? 0930 Temp. 37.2oC (98.9oF) HR 110 bpm RR 42 breaths/min O2 88% on RA Assessment Wheezing, dyspnea, visibly anxious, visualization of swollen tongue and rash surrounding mouth

Following chest percussion, a respiratory therapist auscultates a patient’s chest and hears coarse low-pitch, gurgling sounds around the hilar area. These sounds should be recorded in the patient’s medical record as:

A patient with history of shortness of breath has a FEV1 of 1.0 L before use of a bronchodilator and a FEV1 of 1.25 L after use of a bronchodilator. These results indicate:

A 26 year old patient has been receiving mechanical ventilation in the assist/control mode for 48 hours. The sensitivity is set at -2 cm H2O. The patient is awake and periodically breathing out of phase with the ventilator. Arterial blood gas results with an FIO2 of 0.40 are as follows: pH                   7.43PaCO2               37 torrPaO2                  82 torrHCO3                24 mEq/LBE                  -2 mEq/LWhich of the following should the respiratory therapist do?

A 17 year-old female who weighs 50 kg (110 lb) is admitted to the surgical intensive care unit following open laparotomy and repair of the liver laceration sustained during a fall. The patient is intubated and recieving volume-controlled mechanical ventilation.

The respiratory therapist notes intercostal retractions and paradoxical chest-abdominal motion during inspiration. The therapist should do which of the following to improve ventilator synchrony?

A 65 year old patient with COPD is recieving 28% oxygen by a tracheostomy collar through an 8.0 mm cuffed tracheostomy tube. The patient’s medical history is signficant for respiratory failure with mechanical ventilation and difficulty with tracheostomy tube removal. The patient occasionally requires nocturnal mechanical ventilation. To slowly progress to decannulation, the respiratory therapist should recommend:

Which of the following is the best way to determine a patient’s spontaneous minute ventilaton?

While evaluating a patient’s thorax, the respiratory therapist observes paradoxical movement of the left chest, which is most consistent with:

Which of the following is most likely responsible when a pressure-cycled ventilator fails to cycle to expiration?

Which of the following is used to calibrate the mouth flow transducer of a body plethysmograph?
