TESTBANK Chapter Title: Shock
Chapter #: 38
1. Shock syndrome can best be described as a:
1. physiologic state resulting in hypotension and tachycardia.
2. generalized systemic response to inadequate tissue perfusion.
3. degenerative condition leading to death.
4. condition occurring with hypovolemia that results in irreversible hypotension.
2. Hypovolemic shock that results from an internal shifting of fluid from the intravascular space to the extravascular space is
known as:
1. absolute hypovolemia.
2. distributive hypovolemia.
3. relative hypovolemia.
4. compensatory hypovolemia.
3. The nursing measure that can best enhance large volumes of fluid replacement in hypovolemic shock is:
1. insertion of a large-diameter peripheral intravenous catheter.
2. positioning the patient in the Trendelenburg position.
3. forcing at least 240 ml of fluid each hour.
4. administering IV’s under pressure.
4. The main cause of cardiogenic shock is:
1. an inability of the heart to pump blood forward.
2. hypovolemia, resulting in decreased stroke volume.
3. disruption of the conduction system when reentry phenomenon occurs.
4. an inability of the heart to respond to inotropic agents.
5. Which of the following hemodynamic parameters supports the diagnosis of cardiogenic shock?
1. Decreased right atrial pressure (RAP)
2. Decreased pulmonary artery wedge pressure (PAWP)
3. Increased cardiac output (CO)
4. Decreased cardiac index (CI)
6. IgE-mediated anaphylactic shock occurs as a result of:
1. direct activation of mast cells.
2. laryngeal edema.
3. an antigen entering on a repeat exposure, triggering a secondary immune response.
4. the systemic inflammatory response.
7. With anaphylactic shock, which mechanism results in a decreased cardiac output?
1. Peripheral vasodilation
2. Histamine release
3. Decreased alveolar ventilation
4. Fluid retention resulting in congestive heart failure
8. Which of the following drugs promotes bronchodilation and vasoconstriction?
1. Solu-Medrol
2. Gentamicin
3. Atropine
4. Epinephrine

9. The patients at highest risk for neurogenic shock are those who have had:
1. a stroke.
2. a spinal cord injury.
3. Guillain-Barré syndrome.
4. a craniotomy.
Questions 10-12 refer to the following situation. Ms. H. has been on the medical floor for 1 week following a vaginal
hysterectomy. A urinary catheter was inserted. CBC results have revealed escalating white blood cell counts. Ms. H. is transferred
to the critical care unit when her condition deteriorates. She is diagnosed with septic shock.
10. A pulmonary artery catheter is placed. Which of the following hemodynamics would you expect to find?
1. CO 8 L/min
2. RAP 17 mm Hg
3. PAWP 23 mm Hg
4. Systemic vascular resistance (SVR) 1100
11. Which of the following is the pathophysiologic mechanism that results in septic shock?
1. Bacterial toxins lead to vasodilation.
2. Increased white blood cells are released to fight invading bacteria.
3. Microorganisms invade organs such as the kidneys and heart.
4. Increase of white blood cells leads to decreased red blood cell production and anemia.
12. The medical management of Ms. H.’s condition is aimed toward:
1. limiting fluids to minimize the possibility of congestive heart failure.
2. finding and eradicating the cause of infection.
3. discontinuing invasive monitoring as a possible cause of sepsis.
4. administering vasodilator substances to increase blood flow to vital organs.
