Certified Emergency Nursing Exam - Questions
Answered With Expert Insight
Shock Right Ans - State of impaired tissue perfusion resulting from
circulatory failure.
Hypovolemic Shock Right Ans - Decreased cellular perfusion secondary to
lack of circulating volume or not ENOUGH GAS.
Cardiogenic Shock Right Ans - 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 Right Ans - 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: Right Ans - microvascular thrombosis
disseminated intravascular coagulation (DIC)
Compensated Shock Right Ans - When patient is able to maintain blood
pressure. Body attempting to maintain homeostasis. Increases perfusion to
brain, decreases blood flow to kidneys.
Uncompensated Shock Right Ans - Shock at cellular level. Intracellular fluid
leaks into interstitium causing third spacing and edema, bp decreases, hr
increases, respiratory rate increases,
Hypovolemic Shock Right Ans - Blood or fluid loss reduces circulating
blood volume and cardiac output.
Mean Arterial Pressure Right Ans - MAP = (Systolic pressure +
2(Diastolic) / 3
Want a MAP above 60
Hypovolemic shock interventions Right Ans - Airway control, control
bleeing or fluid loss, restore volume, NS 0.9%, Adult 1-2L bolus, Pedi 20ml/kg.
Never use Dextrose
, Cardiogenic Shock Right Ans - Inadequate tissue perfusion as a result of
decreased cardiac output despite adequate intravascular volume. Most
common is MI. Pump Failure
Cardiogenic Shock Interventions Right Ans - 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 Right Ans - Abnormal distribution of intravascular
volume. Can me anaphylactic, septic, neurogenic
Distributive Shock (Anaphylaxis) Right Ans - Acute life threatening allergic
reaction to individuals exposed to an antigen to which they have become
hypersensitive.
Anaphylactic Shock Interventions Right Ans - IM epi 1:1000 repeat in 15-
20 min as needed. Albuterol, H1 abd H2 blockers, Corticosteroids.
Septic Shock Right Ans - 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 Right Ans - Positive inotropes, vasopressors,
fluid resuscitation, antibiotics
Neurogenic Shock Right Ans - Loss of the sympathetic nervous system
"fight or flight" response is lost and the rest of digest system is unopposed.
Bradycardia, bradypnea, hypotension, priapism.
Neurogenic shock interventions Right Ans - abc's, fluids, vasopressors,
atropine for bradycardia, high dose corticosteroids not recommended.
Obstructive shock Right Ans - cardiac output and tissue perfusion are
inadequate because of resistance to ventricular filling. Causes pericardial
tamponade, tension pneumo, pulmonary embolism
