Chapter 12. Shock & Acute Pulmonary Failure in Surgical Patients

++
++
++

Shock can be caused by

++
++
++

A. Depletion of intravascular volume

++
++

B. Loss of autonomic control of the vasculature

++
++

C. Severe untreated systemic inflammation

++
++

D. Both A and C

++
++

E. All of A, B, and C

+
++

E. All of A, B, and C

++
++
++

Hypothermia in hemorrhagic shock

++
++
++

A. Is of limited risk in the initial 24 hours after injury

++
++

B. Can contribute to coagulopathy

++
++

C. Is unusual in the trauma population outside of cold-weather or water-immersion injuries

++
++

D. Is best treated by warming the ambient room temperature

++
++

E. Is a secondary concern that can be addressed after the care of injuries

+
++

B. Can contribute to coagulopathy

++
++
++

Cardiac or great vessel compressive shock

++
++
++

A. Can be caused by pericardial tamponade

++
++

B. May accompany tension pneumothorax

++
++

C. Is worsened by the need for positive pressure ventilation

++
++

D. Cannot be caused by intra-abdominal injury

++
++

E. All of A, B, and C

+
++

E. All of A, B, and C

++
++
++

The pulmonary failure of shock, trauma, and sepsis

++
++
++

A. Can be related to products of coagulation and inflammation that are washed out from the damaged tissues

++
++

B. Can be effectively treated with a combination of antibiotics and corticosteroids

++
++

C. Is always related to systemic infection

++
++

D. Is caused by a decrease in pulmonary vascular permeability

++
++

E. Both A and C

+
++

A. Can be related to products of coagulation and inflammation that are washed out from the damaged tissues

++
++
++

All of the following are true about pressure support ventilation, except

++
++
++

A. PSV is a pressure-limited ventilator mode

++
++

B. PSV includes a set inspiratory time

++
++

C. PSV breaths are patient-triggered
