Question: 1 / 400

Which type of shock is NOT caused by a fluid loss from the body?

Hypovolemic shock

Obstructive shock

Cardiogenic shock

Cardiogenic shock is characterized by the heart's inability to pump blood effectively, leading to inadequate tissue perfusion. This type of shock arises primarily from issues within the heart itself, such as severe myocardial infarction, heart failure, or other cardiac conditions, rather than from a loss of fluid volume as seen in hypovolemic shock.

In contrast, hypovolemic shock directly stems from significant fluid loss due to causes like hemorrhage or dehydration. Obstructive shock occurs when blood flow is obstructed, such as in cases of tension pneumothorax or pulmonary embolism, and distributive shock involves systemic vasodilation, which may be caused by conditions like septic shock or anaphylaxis. These types of shock are all related to alterations in fluid dynamics or volume, highlighting the unique nature of cardiogenic shock as one that is linked to cardiac function rather than fluid deficiency.
