1 1 pts A patient with respiratory

1 1 pts A patient with respiratory failure has hemodynamic monitoring and is receiving mechanical ventilation. The peak end-expiratory pressure (PEEP) was just increased to 12 cm H2O from 8 cm H20. Which information indicates that a change in the ventilator settings may be required? Group of answer choices The arterial line showing a decrease in blood pressure The pulmonary artery pressure (PAP) decreased The cardiac monitor shows a heart rate of 58 beats/min The pulmonary artery wedge pressure (PAWP) is increased 2 1 pts What is significant to note regarding respiratory drive for patients with chronically high PaCO2 such as those with severe COPD? Group of answer choices They respond only to changes in PaCO2 Their hypercapnic ventilatory drive is lost Their hypoxia ventilatory drive is lost They will need high peep and FiO2 3 1 pts A patient is admitted to the ICU for sepsis and was intubated for acute respiratory distress syndrome (ARDS). Throughout the day you notice the peak pressures are rising as well as the static pressure. He is also getting more tachycardic. Where do you think the problem lies with this particular patient? Group of answer choices His compliance is decreasing His resistance is increasing His elasticity is increasing His alveoli are increasing 4 1 pts What is tidal volume? Group of answer choices An augmentation of flow rate during spontaneous inspiration Prevents the return of intrapulmonary pressure to equal extrapulmonary pressure at the end of expiration The number of mechanical breaths delivered each minute Volume of air entering (inhaled) or leaving (exhaled) the lung with each breath 5 1 pts What are the indications for initiating mechanical ventilation? Group of answer choices Hypoxia/Hypercarbia Seizure Airway protection Secretions Both A&C Both B&D All of the above 6 1 pts A major complication of bag-valve-mask is what? Group of answer choices Over inflation of the lungs Trauma to the face Inflation of the stomach Trauma to the esophagus 7 1 pts The resident you are working with today orders bipap on a hypercarbic patient with decreased mental status. You are concerned the patient may be unable to protect his airway. What is your action? Bipap settings: Ipap 10, Epap 8, FiO2 50% Group of answer choices Increase the Ipap to 15 Increase the Epap to 10 Discontinue the order and prepare for intubation These are the appropriate setting for this patient 8 1 pts What is the difference between CPAP and Bipap? Group of answer choices Cpap is for hypercapnia and Bipap is for sleep apnea They are both the same, they are just different brands Cpap and bipap are different types of oxygen machines Bipap is commonly used for pts with hypercapnia and CPAP is used for sleep apnea 9 1 pts A patient presents to the ER with shortness of breath. He has a history of HTN and COPD. He states that he wears bipap at night but has not been able to wear it recently because it broke. His pulse oximetry in the ER is 85%. ABG: Ph: 7.25, PCO2: 78, HCO3: 18, Pa02: 65, SaO2: 88%. What would your next step be? Group of answer choices Intubate the patient and start mechanical ventilation with AC 12/Tidal Volume 400/ FiO2 50/ Peep 5. Start High Flow Nasal Cannula at 40 liters 50 % for peep affect. Initiate Bipap 20 inspiratory pressure over 5 expiratory pressure with a backup rate of 12 with 100% FiO2 Place the patient on 2 liters nasal cannula 10 1 pts What is the best description of minute ventilation? Group of answer choices Volume of air exhaled in 1 second Amount of air taken over a minute Forced expiratory flow that influences the FVC curve Maximum air expired
