Question 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
Question 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
Question 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
Question 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
Question 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
Question 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
Question 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
Question 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
Question 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
Question 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
