Not initiating life support is known as __________. | withholding |
Removing life support once it has been initiated is known as __________. | withdrawing |
DNR refers to medical orders for ______________. | "Do Not Resuscitate" |
An end-tidal CO2 detector assists in verifying endotracheal tube placement. | True |
Cyanosis is an early sign of hypoxemia. | False |
Mechanical ventilation is commonly used in critical care settings and it has a low risk for complications. | False |
Pulse oximetry is a noninvasive method to measure arterial oxygen saturation. | True |
Respiratory acidosis may occur when a patient hyperventilates. | False |
Saline should be routinely instilled into endotracheal tubes to loosen secretions from the respiratory tract. | False |
Ventilator-associated pneumonia can be prevented by suctioning the patient every 2 hours. | False |
The etiology of pulmonary edema in acute respiratory distress syndrome is related to: | Damage to the alveolar-capillary membrane |
Mrs. Clemons presents to the emergency department in acute respiratory distress. She has a longstanding history of chronic obstructive pulmonary disease. What position would be best tolerated? | Stretcher with head of bed as high as it will go |
Which of the following is appropriate for initial treatment of hypoxemia in Mrs. Clemons? | Oxygen via venturi-mask at 40% oxygen |

A common nursing diagnosis for patients with respiratory failure, regardless of etiology, is ____________________. | impaired gas exchange |
Acute respiratory distress syndrome results in _______________ pulmonary edema. | noncardiogenic |
