Pulse Oximetry Accuracy and Skin Tone
Pulse oximetry derived oxygen saturation (SpO2) readings may be up to 1.5 percentage points higher for critically ill patients with darker skin tone than those with lighter skin tone.

Critical Care
Transfusion Threshold in Acute Brain Injury
A liberal transfusion threshold, targeting a hemoglobin of 9g/dL compared to a restrictive strategy targeting a hemoglobin of 7g/dL, was associated with a lower risk of unfavorable neurological outcome at 180 days in patients with acute brain injury.
- True
- False
Volume 40.4 - Question 31
Noninvasive Ventilation for Preoxygenation During Emergency Intubation
Among critically ill adults undergoing tracheal intubation, preoxygenation with noninvasive ventilation (bilevel positive airway pressure) results in a lower incidence of hypoxemia during intubation than preoxygenation with an oxygen mask.
- True
- False

Prevention of Ventilator-Associated Pneumonia
In patients with acute brain injury, a single (2g) ceftriaxone dose decreased the risk of early ventilator-associated pneumonia.
- True
- False

Tazocin for Sepsis
Among patients with suspected sepsis treated with vancomycin and no clear indication for anti-anaerobic coverage, administration of piperacillin-tazobactam is associated with higher mortality compared with cefepime.
- True
- False

Norepinephrine in Septic Shock
Comparing early vs. late initiation of norepinephrine in patients with septic shock, each of the following is decreased except:

- ICU length of stay
- Time to achieve target mean arterial pressure
- Volume of intravenous fluids within six hours

Intravenous Fluids in Critically Ill Patients
Among critically ill patients requiring fluid challenges, use of a balanced solution compared with 0.9% saline solution significantly reduces 90-day mortality.
- True
- False
Volume 37.2 - Question 20
Effect of Fluid Bolus Administration Among Critically Ill Patients Undergoing Tracheal Intubation
Among critically ill adults undergoing tracheal intubation, administration of an intravenous fluid bolus compared with no fluid bolus significantly decreased the incidence of cardiovascular collapse.
- True
- False

Haloperidol for the Treatment of Delirium in ICU Patients
Among patients in the ICU with delirium, treatment with haloperidol will lead to a significantly fewer days alive and out of the hospital at 90 days than placebo.
- True
- False
Volume 38.3 - Question 33

In non-intubated adults with hypoxemic respiratory failure due to covid-19, awake prone positioning compared with usual care results in which one of the following significantly improved outcomes?
- Mortality
- Risk of endotracheal intubation
- Hospital length of stay
- Ventilator-free days
