MULTIPLE CHOICE

1. Shock syndrome can best be described as a

ANS:  B

Shock is a complex pathophysiologic process that often results in multiple organ dysfunction syndrome and death. All types of shock eventually result in ineffective tissue perfusion and the development of acute circulatory failure.

2. Hypovolemic shock that results from an internal shifting of fluid from the intravascular space to the extravascular space is known as

ANS:  C

Hypovolemia results in a loss of circulating fluid volume. A decrease in circulating volume leads to a decrease in venous return, which results in a decrease in end-diastolic volume or preload.

3. The nursing measure that can best enhance large volumes of fluid replacement in hypovolemic shock is

ANS:  A

Measures to facilitate the administration of volume replacement include insertion of large-bore peripheral intravenous catheters; rapid administration of prescribed fluids; and positioning the patient with the legs elevated, trunk flat, and head and shoulders above the chest.

4. The main cause of cardiogenic shock is

ANS:  A

Cardiogenic shock is the result of failure of the heart to effectively pump blood forward. It can occur with dysfunction of the right or the left ventricle or both. The lack of adequate pumping function leads to decreased tissue perfusion and circulatory failure.

5. Which of the following hemodynamic parameters supports the diagnosis of cardiogenic shock?

ANS:  D

Assessment of the hemodynamic parameter of patients in cardiogenic shock reveals a decreased cardiac output and a cardiac index less than 2.2 L/min/m².
