Ontario Paramedic Practice Exam

Question: 1 / 400

Which type of shock is characterized by an inadequate blood volume?

Cardiogenic shock

Hypovolemic shock

Hypovolemic shock is characterized by an inadequate blood volume, which leads to a decreased perfusion of tissues and organs. This type of shock typically occurs when there is significant fluid loss, which can result from conditions such as severe dehydration, hemorrhage, or burns. In hypovolemic shock, the body struggles to supply enough blood and oxygen to meet the metabolic demands of tissues, leading to a cascade of physiological responses in an attempt to compensate for the deficit.

Patients experiencing hypovolemic shock often present with symptoms such as rapid heart rate, low blood pressure, cool and clammy skin, and altered mental status due to inadequate perfusion. Understanding the underlying mechanisms of hypovolemic shock is crucial for paramedics and emergency responders to provide timely and effective care, which can include fluid resuscitation and addressing the source of the fluid loss.
