QUESTIONS AND CORRECT DETAILED ANSWERS

(VERIFIED ANSWERS) GRADED A+|| NEW!!

Shock .......ANSWER........State of impaired tissue perfusion

resulting from circulatory failure.

Hypovolemic Shock .......ANSWER........Decreased cellular

perfusion secondary to lack of circulating volume or not

ENOUGH GAS.

Cardiogenic Shock .......ANSWER........Decreased cellular perfusion

secondary to maldistribution of oxygen to the periphery. Its like

adding a larger engine without increasing the size of the tank.

Obstructive shock .......ANSWER........Decreased cellular perfusion

secondry to obstruction of blood into or out of the ventricles (eg.

pulmonary emboli, tamponade, tension pneumo. Like getting dirt

or blockage in the fuel line.

Prolonged lactic acidosis leads to microvascular thrombosis and

disseminated intravascular coagulation .......ANSWER........

Compensated Shock .......ANSWER........When patient is able to

maintain blood pressure. Body attempting to maintain

homeostasis. Increases perfusion to brain, decreases blood flow

to kidneys.

Uncompensated Shock .......ANSWER........Shock at cellular level.

Intracellular fluid leaks into interstitium causing third spacing and

edema, bp decreases, hr increases, respiratory rate increases,

Hypovolemic Shock .......ANSWER........Blood or fluid loss reduces

circulating blood volume and cardiac output.

Mean Arterial Pressure .......ANSWER........MAP = (Systolic

pressure + 2(Diastolic) / 3

,Page 3 of 31


Want a MAP above 60

Hypovolemic shock interventions .......ANSWER........Airway control,

control bleeing or fluid loss, restore volume, NS 0.9%, Adult 1-2L

bolus, Pedi 20ml/kg. Never use Dextrose

Cardiogenic Shock .......ANSWER........Inadequate tissue perfusion

as a result of decreased cardiac output despite adequate

intravascular volume. Most common is MI. Pump Failure

Cardiogenic Shock Interventions .......ANSWER........Airway with

PEEP will force pulmonary edema fluid out of the lung

interstitium. Decrease preload by position, nitro, diuretics,

morphine. Cardiac cath, angioplasty.

Distributive Shock .......ANSWER........Abnormal distribution of

intravascular volume. Can me anaphylactic, septic, neurogenic

Distributive Shock (Anaphylaxis) .......ANSWER........Acute life

threatening allergic reaction to individuals exposed to an

antigen to which they have become hypersensitive.

Anaphylactic Shock Interventions .......ANSWER........IM epi 1:1000

repeat in 15-20 min as needed. Albuterol, H1 abd H2 blockers,

Corticosteroids.

Septic Shock .......ANSWER........Systemic Inflammatory response

syndrome (SIRS). Sepsis with organ dysfunction, cardio failure

leading to hypotension, Resp failure leading to hypoxia, Renal

failure leading to oliguria and azotemia. MODS, multiple organ

dysfumction syndrome.

Septic Shock Interventions .......ANSWER........Positive inotropes,

vasopressors, fluid resuscitation, antibiotics

Neurogenic Shock .......ANSWER........Loss of the sympathetic

nervous system "fight or flight" response is lost and the rest of

digest system is unopposed. Bradycardia, bradypnea,

hypotension, priapism.
