Physiological Adaptation Q 107

---

The nurse is aware that the following terms used to describe reduced cardiac output and perfusion impairment due to ineffective pumping of the heart is:

  

     A. Anaphylactic shock

     B. Cardiogenic shock

     C. Distributive shock

     D. Myocardial infarction (MI)

    

    

Correct Answer: B. Cardiogenic shock

---

Cardiogenic shock is shock related to ineffective pumping of the heart.

---

Option A: Anaphylactic shock results from an allergic reaction. This severe reaction happens when an over-release of chemicals puts the person into shock.

Option C: Distributive shock results from changes in the intravascular volume distribution and is usually associated with increased cardiac output.

Option D: MI isn’t a shock state, though in most cases, a lack of oxygen to the heart, usually from a heart attack, damages its main pumping chamber. Without oxygen-rich blood circulating to that area of the heart, the heart muscle can weaken and go into cardiogenic shock.
