Which of the following best describes this patient’s condition? A. chronic hypoxemic respiratory failure B. acute hypercapnic respiratory failure C. chronic hypercapnic respiratory failure D. acute hypoxemic respiratory failure

In intubated patients, what do sources of increased imposed work of breathing include? I. endotracheal tube II. ventilator circuit III. auto-PEEP   A. I and II B. I and III C. II and III D. I, II and III

A patient has an arterial blood gas that measured PaO2 180 mmHg.  What would the pulse oximeter SpO2 read?

The patient was placed on 10 LPM simple O2 mask and his SpO2 increased to 95% but the patient is still breathing at a rate of 35 breaths/min with use of accessory muscles for breathing. What should be done next?   Choose only ONE

The patient was unresponsive and not breathing. Cardiopulmonary resuscitation was started. You assisted the physician to intubate the patient with a  7.5 ETT  at 26 cm marking at the teeth. What should be assessed just after intubation to assess the placement of the airway?   Select as MANY as appropriate

Which of the following is true of pulse oximetry? 1. An emitter puts out a wavelength of light specific to deoxygenated hemoglobin which is detected by a sensor 2. An emitter puts out a wavelength of light specific to oxygenated hemoglobin which is detected by a sensor 3.  Variance in light is used to detect volume changes which is displayed as a pulse 4. The pressure of oxygen (PO2) is measured, and then displayed as a percentage

After placing the patient on an air-entrainment mask of 0.50 FIO2, the patient’s respiratory rate has decreased to 24 breaths/min with a SpO2 of 96%.  Previous Assessments: HR 120 bpm, Respiration 35 breaths/min, BP 130/85 mmHg, SpO2 85% Lung sounds: Rhonchi and wheezes in the RUL and RML. Temperature: of 102 F No Cyanosis Strong productive cough with moderate amount of thick yellow secretions. What should be done next?   Choose only ONE
