Question

1. ______ develops when the heart muscle can no longer generate enough pressure to circulate the blood to all organs.

a. pump failure
b. cardiogenic shock
c. a myocardial infarction
d. congestive heart failure

1. neurogenic shock usually results from damage to the spinal cord at the:

a. cervical level
b. thoracic level
c. lumbar level
d. sacral level

1. which of the following statements about septic shock is false?

a. there is an insufficient volume of fluid in the container.
b. the fluid that has leaked out often collects in the respiratory system.
c. there is a larger - than - normal vascular bed to contain the smaller - than - normal volume of intravascular fluid.
d. there is damage to the spinal cord, resulting in vasodilation.

1. neurogenic shock causes hypoperfusion due to:

a. widespread dilation of the vascular system
b. massive vasoconstriction
c. low circulating blood volume
d. obstruction of blood flow from the heart

1. hypovolemic shock is a result of:

a. widespread vasodilation
b. low circulating blood volume
c. massive vasoconstriction
d. pump failure

Explanation:

• Question 9: Cardiogenic shock occurs when the heart (as a pump) fails to generate enough pressure to circulate blood. Pump failure is a very general term. Myocardial infarction is a cause (not the condition described). Congestive heart failure has more to do with fluid accumulation over time rather than the immediate pressure - circulation issue described.
• Question 10: Neurogenic shock usually results from damage to the cervical level of the spinal cord as it can disrupt the sympathetic nervous system which is crucial for vascular tone regulation. Damage at lower levels (thoracic, lumbar, sacral) has a less profound impact on the overall vascular regulation compared to the cervical level.
• Question 11: Septic shock is due to infection - induced issues like vasodilation, increased vascular permeability (fluid leakage), etc. Damage to the spinal cord causing vasodilation is characteristic of neurogenic shock, not septic shock.
• Question 12: Neurogenic shock causes hypoperfusion (inadequate blood flow) because of widespread dilation of the vascular system (due to loss of sympathetic tone). Massive vasoconstriction would not cause hypoperfusion in the context of neurogenic shock. Low circulating blood volume is more related to hypovolemic shock. Obstruction of blood flow from the heart is related to obstructive shock.
• Question 13: Hypovolemic shock is a result of low circulating blood volume (e.g., due to hemorrhage, fluid loss). Widespread vasodilation is more related to distributive shocks (like septic, neurogenic). Massive vasoconstriction is not the cause of hypovolemic shock. Pump failure is related to cardiogenic shock.

1. B. Cardiogenic shock
