EMT Test #4: Shock

The term "shock" is MOST accurately defined as:

• A decreased supply of oxygen to the brain

• Decreased circulation of blood within the venous circulation

• Cardiovascular collapse leading to inadequate perfusion

• Decreased function of the respiratory system leading to hypoxia

What are the three components of the perfusion triangle?

• Heart, blood vessels, blood

• Heart, brain, lungs

• Plasma, red blood cells, platelets

• Arteries, veins, capillaries

You suspect your patient is in shock; you note the patient's skin is pale. This is likely due to?

• peripheral vasodilation

• an increased heart rate

• hypothermia

• peripheral vasoconstriction

Shock due to severe infection is called:

• Neurogenic shock

• Septic shock

• Anaphylactic shock

• Hypovolemic shock

Your patient has a decreased cardiac output and poor myocardial contractility. this will likely lead to?

• Septic shock

• Hypovolemic shock

• Cardiogenic shock

• Neurogenic shock

Foods, medications, and insects are common causes of:

• Anaphylactic shock

• Neurogenic shock

• Cardiogenic shock

• Septic shock

Anaphylactic shock is typically associated with:

• A severe headache

• Localized welts

• Bradycardia

• Urticaria

As you approach a patient lying at the side of the roadway, you observe severe bleeding from the leg. What should your first action be?

• Open the airway.

• Check for a pulse.

• Control the bleeding.

• Administer oxygen.

When should nonlifesaving interventions be performed for your multisystem trauma patient?

• En route to the hospital

• Prior to transport

• Immediately after the injuries are discovered

• During the primary assessment

To protect vital organs the body compensates by directing the flow away form the organs that are more tolerant of low flow such as?

• The brain

• The lungs

• The heart

• The skin
