A condition of extreme hypersensitivity to a foreign protein or other substance that results in low blood pressure is:

anaphylactic shock

Rationale: Anaphylactic shock is an allergic reaction that is widespread throughout the body. It is an emergency condition that requires immediate attention. The main symptoms of anaphylactic shock are low blood pressure, dizziness, labored breathing, and swelling of the airway. The primary treatment for anaphylactic shock is to administer oxygen and adrenaline, which will help maintain tissue perfusion and reduce swelling of the airway.


Shock that results from severe blood and fluid loss is:

hypovolemic shock

Rationale: Hypovolemic shock is an emergency condition in which severe blood and fluid loss make the heart unable to pump enough blood to the body, which can cause many organs to stop working. Blood loss can be due to bleeding from cuts or injury, or internal bleeding such as from the gastrointestinal tract. The amount of blood in your body may drop when you lose too many other body fluids as well, such as with diarrhea, vomiting, and burns. Symptoms of hypovolemic shock are anxiety, cool skin, confusion, and pale skin color. The goal of treatment is to replace blood and fluids. Medicines such as dopamine, dobutamine, epinephrine, and norepinephrine may be needed to increase blood pressure and cardiac output.


A patient that suffers a myocardial infarction (MI) is at risk of developing:

cardiogenic shock

Rationale:

A patient that has a spinal cord injury after a motor vehicle accident is at risk of developing:

neurogenic shock

Rationale:

A mechanical obstruction that interferes with the heart's ability to generate adequate cardiac output can result in:

obstructive shock

Rationale:

A drop in blood pressure that results from a severe infection in the body is:

septic shock

Rationale:

A syndrome in which there is a sudden drop in blood pressure that results in inadequate blood supply to all body tissues is:

shock

Rationale:

The top priority in resuscitating a patient from shock is:

restoration of tissue perfusion

Rationale:

All of the following are types of shock, except:

metabolic

Rationale:

An early compensatory response mechanism to shock is:

vasoconstriction
