The patient was intubated and placed on a ventilator with PEEP. Chest tube was deferred at this time. Upon reassessment, which finding is most concerning? A. Severely diminished breath sounds on the right B. Guarding in the right upper quadrant
C. Ecchymosis in the right upper quadrant D. Crepitus to the right chest A. Severely diminished breath sounds on the right
- A patient with a traumatic brain injury has a mean arterial pressure (MAP) of 65 mm Hg (8.66 kPa) and an intracranial pressure (ICP) of 22 mm Hg (2.93 kPa). Which finding is most likely an indication of the body's response to these findings? A. Increased respiratory effort B. Widening pulse pressure C. Reflex tachycardia D. Reflex hypotension B. Widening pulse pressure Rationale: Head and Torso Trauma\Head Trauma This patient has a CPP (MAP − ICP) of less than 60 mm Hg (8 kPa) which is associated with poor outcomes.

Under which circumstance will it be harder for the hemoglobin to release oxygen to the tissues? A. Decreased pH B. Elevated carbon dioxide level C. Decreased body temperature D. Increased metabolic demand Rationale: Primary Assessment\Airway and Ventilation If the blood is not sufficiently warmed when transfused, it can produce hypothermia.
