Shock Quiz

1- Identify the FALSE statement:

Hypovolemic shock is associated with low cardiac output
Septic shock is associated with cold clammy skin
Cardiogenic shock is associated with arrhythmia, MI, and myocarditis
Extracardiac obstructive shock is associated with cardiac tamponade, pneumothorax, and pulmonary emboli

2- Which stage of shock is associated with the worsening of tissue hypoperfusion and onset of worsening circulatory and metabolic imbalances, including acidosis?

Initial nonprogressive phase
Developing phase
Progressive stage
Irreversible stage

3- What are characteristics of the irreversible stage of shock?

The worsening of tissue hypoperfusion and the onset of worsening circulatory and metabolic imbalances, including acidosis
The body tries to initiate compensatory mechanisms
Nothing can correct the hemodynamic defect
Tissue and cell damage is too great tissue and necrosis of the tissue will occur even if the underlying hemodynamic defect is corrected

4- Your patient is in the progressive stage of shock. If the shock is not corrected and tissue hypoxia occurs, what would happen with the patients metabolism?

The tissues will undergo anaerobic metabolism, creating lactic acid and lowering the tissue pH
Vasomotor reflex of arteriolar constriction that reduces pooling of blood in the microcirculation
Metabolism would be unaffected by the lower oxygen level for the 2-3 hours

5- Which type of shock is associated with low blood levels?

Hypovolemic shock
Septic shock
Anaphylactic shock
Cardiogenic shock

6- What characteristics distinguish septic shock from hypovolemic and cardiogenic shock?

Septic shock patients will present with cool skin due to vasoconstriction
Patients with septic shock will have a bluish color to their skin
Vasodilation will lead to warm flushed skin in septic shock patients
Septic shock patients present with pulsus paradoxus

7- True or False: Septic shock should present with a normal or high cardiac output.

True
False

8- True or False: Hypovolemic shock should typically present with a reduced cardiac output.

True
False

9- Anaphylactic schock is associated with which type of hypersensitivity?

Type I (immediate)
Type II (cytotoxic)
Type III (immunocomplex)
Type IV (cell mediated)

10- Which is true in regard to systemic anaphylaxis?

Anaphylaxis occurs due to the IgE reacting with the foreign object ultimately leading to release of vasoconstictors. The vasoconstrictors lead to severe hypertension and bronchospasms
Systemic anaphylaxis is associated with Vomiting, abdominal cramps, diarrhea, and hypertension
Systemic anaphylaxis occurs due to mast cell degranulation and release of mediators that causes acute vasodilation. Which can ultimately lead to increased vascular permeability, bronchospasms, and hypotension
