30 Questions
What is the primary cause of distributive shock?
Neurogenic or medical causes
What is the hallmark of the irreversible stage of shock?
Systemic vital organ failure
What is the primary purpose of frequently monitoring blood pressure in shock patients?
To determine organ perfusion
What is the main challenge in diagnosing shock in the early stages?
Blood pressure is not a reliable indicator
What is the primary difference between the compensated and decompensated stages of shock?
The body's ability to compensate for blood loss
What is the primary goal of assessing a patient in shock?
To recognize shock and initiate treatment
What may persist in some cases of severe hemorrhage despite hemorrhage control and IV volume infusion?
Shock symptoms and signs
What should be done early during evaluation and treatment of hemorrhage?
Place the patient on an ECG monitor
What should be considered if IV access cannot be obtained in a critical patient?
Using IO vascular access
What is the purpose of hemostatic agents in hemorrhage control?
To stop hemorrhage by facilitating clotting
When should hemostatic agents be used?
When pressure and a tourniquet cannot stop bleeding
When should IV access be gained in a patient with severe hemorrhage?
During transportation
What is the recommended approach to fluid resuscitation in managing shock due to internal hemorrhage?
Provide minimal fluids until hemorrhage control is obtained
Why is it important to maintain a cerebral perfusion pressure of at least 60 mmHg in patients with traumatic brain injury?
To maintain cerebral function and prevent further neurologic deterioration
What should be considered if unable to quickly establish an intravenous line in a patient with internal hemorrhage?
Consider IO vascular access
What is a potential consequence of administering large amounts of IV fluids to patients with uncontrolled internal hemorrhage?
Increased blood pressure and potential increased internal bleeding
What is NOT indicated for internal hemorrhage?
Hemostatic agents
Why are IV fluids not a replacement for red blood cells in patients with hemorrhagic shock?
IV fluids cannot carry oxygen
What is the primary concern in the treatment of moribund trauma patients with blood pressures under 50 mmHg systolic?
Maintaining some degree of circulation
What should be monitored in a patient with internal hemorrhage?
Heart rate and oxygen saturation using pulse oximetry
What is the recommended target systolic blood pressure in an adult with traumatic brain injury and suspected hemorrhagic shock?
110 mmHg
Why should early blood transfusion be prioritized in severe cases of hemorrhagic shock?
To replace lost red blood cells and oxygen-carrying capacity
What should be done when there is a delay in transporting patients with hemorrhagic shock?
Document the circumstances carefully in the patient care report
What should guide therapy for patients with probable exsanguinating internal hemorrhage, pending further research?
Local medical direction
What is the primary reason for shock to occur if one of the four components of normal perfusion is absent?
Insufficient volume of fluid in the vascular system
What is the term for shock caused by insufficient volume within the vascular system?
Hypovolemic shock
What is the formula for calculating pulse pressure?
SBP - DBP
What is the primary goal of managing shock?
Maintaining circulation through an adequate heart rate and intravascular volume
What is the term for the uncontrolled external hemorrhage type of shock?
External hemorrhage–uncontrolled
What is the first basic rule of shock management?
Maintain the airway
This quiz covers the causes of shock related to trauma, including intravascular volume loss, distributive shock, obstructive shock, and cardiogenic shock.
