MULTIPLE CHOICE

1. Disseminated intravascular coagulation (DIC) is also known as:

ANS:   B

DIC, also known as consumptive coagulopathy, is characterized by both bleeding and thrombosis, which result from depletion of clotting factors, platelets, and red blood cells.

2. The nurse recognizes that sepsis will have what effect on the critical care patient’s risk for DIC?

ANS:   B

Sepsis, particularly that caused by gram-negative organisms, can be identified as the culprit in as many as 20% of cases of DIC, which makes it the most common cause of this disorder.

3. Damage to the endothelium can lead to DIC because of which of the following?

ANS:   A

4. The priority actions of the nurse in working with a patient who has DIC are:

ANS:   C

Assessment and monitoring are the primary weapons in the critical care nurse’s arsenal where DIC is concerned. Knowing the diseases and conditions that are most often associated with DIC and understanding the pathophysiological mechanisms involved enable the critical care nurse to anticipate its development and intervene quickly.
