Week 3 pt 2

Massive release of histamine with consequent vasodilation and hypotension occurs with what type of shock?

Anaphylactic

A patient in septic shock is getting IV fluids but remains hypotensive and the nurse notes third spacing of fluids. What is the mechanism behind these observations?

Capillary leaking of fluids

The nurse is caring for a patient being treated with an Impella device. What statement by the nurse shows good understanding of this treatment?

It is a tiny device that assists the left ventricle

Overproduction of nitric oxide is an important aspect of the pathophysiologic process of what type of shock?

Septic

The nurse is caring for a patient who has acute hemorrhagic shock. The patient's shock index today is 1.08. What does the nurse understand about this value?

This value is concerning.

The majority of cases of anaphylactic shock occur when a sensitized individual comes in contact with

antibiotics

Tachycardia is an early sign of low cardiac output that occurs because of

baroreceptor activity

Administration of a vasodilator to a patient in shock would be expected to

decrease left ventricular afterload.

The therapy that most directly improves cardiac contractility in a patient with systolic heart failure is

digitalis

Lusitropic impairment refers to

impaired diastolic relaxation

Tumor necrosis factor- and interleukin-1 contribute to shock states because they induce production of

nitric oxide

First-degree heart block is characterized by

prolonged PR interval

A patient who was involved in a fall from a tree becomes short of breath. The lung sounds are absent on one side. This patient is experiencing ________ shock.

obstructive

A patient with cold and clammy extremities, low cardiac output, and profound hypotension is likely to be experiencing a progressive stage of ________ shock.

septic

Sepsis has been recently redefined as

systemic inflammatory response to infection

The effect of nitric oxide on systemic arterioles is

vasodilation
