Shock

Question 1

Define: cardiogenic shock.

Answer 1

failure of the pump (heart) and is often the result of a myocardial infarction;
since the heart is no longer an effective pump, fluid backs up in the body and the lungs

Question 2

Define: obstructive shock.

Answer 2

physical obstruction of great vessels or the heart itself;
caused by cardiac tamponade or tension pneumothorax. patient requires management by ALS providers or more complex management at the hospital

Question 3

Define: septic shock.

Answer 3

a systemic infection causes full-body inflammatory response;
the blood vessels to become leaky and dilate, causing the container to enlarge;
patient requires complex management in the hospital

Question 4

Define: neurogenic shock.

Answer 4

involves an injury to the central nervous system, causing the patient’s blood vessels to dilate (container gets bigger);
even though the blood pressure drops, there is no
blood loss

Question 5

Define: anaphylactic shock.

Answer 5

severe allergic reactions can rapidly progress to anaphylactic shock. The body’s response to the allergen causes widespread vasodilation

Question 6

Define: psychogenic shock.

Answer 6

a sudden reaction of the nervous system causes a temporary vasodilation, resulting in syncope (fainting);
it is important to investigate other possible causes of the syncopal episode;
once supine, the patient regains consciousness

Question 7

Define: hypovolemic shock.

Answer 7

caused by a loss of blood or body fluids. It should be suspected first whenever a patient presents with signs and symptoms of shock. Blood loss may be external or
internal secondary to a traumatic injury. Body fluids can be lost due to burns, excessive vomiting, or diarrhea.

Question 8

Define: compensated shock.

Answer 8

body attempts to compensate for blood loss

Question 9

Define: compensated shock.

Answer 9

body employs mechanisms to reverse condition;
presents as increased heart rate, & respiration;
constriction of peripheral circulation (pale & cool skin)

Question 10

Define: decompensated shock.

Answer 10

body’s mechanisms to reverse condition begin to fail;

presents as low blood pressure

Question 11

Define: irreversible shock.

Answer 11

perfusion to organs cannot be restored;
cell damage;
irreparably damaged organs may cause death
