Chapter 66: Shock, Sepsis, and Multiple Organ Dysfunction Syndrome

Lewis: Medical-Surgical Nursing, 10th Edition


MULTIPLE CHOICE

1. A 78-kg patient with septic shock has a pulse rate of 120 beats/min with low central venous

pressure and pulmonary artery wedge pressure. Urine output has been 30 mL/hr for the past 3

hours. Which order by the health care provider should the nurse question?

a. Administer furosemide (Lasix) 40 mg IV.

b. Increase normal saline infusion to 250 mL/hr.

c. Give hydrocortisone (Solu-Cortef) 100 mg IV.

d. Titrate norepinephrine to keep systolic blood pressure (BP) above 90 mm Hg.


ANS: A

Furosemide will lower the filling pressures and renal perfusion further for the patient with

septic shock. Patients in septic shock require large amounts of fluid replacement. If the patient

remains hypotensive after initial volume resuscitation with minimally 30 mL/kg, vasopressors

such as norepinephrine may be added. IV corticosteroids may be considered for patients in

septic shock who cannot maintain an adequate BP with vasopressor therapy despite fluid

resuscitation.

2. A nurse is caring for a patient whose hemodynamic monitoring indicates a blood pressure of

92/54 mm Hg, a pulse of 64 beats/min, and an elevated pulmonary artery wedge pressure

(PAWP). Which intervention ordered by the health care provider should the nurse question?

a. Elevate head of bed to 30 degrees.

b. Infuse normal saline at 250 mL/hr.

c. Hold nitroprusside if systolic BP is less than 90 mm Hg.

, d. Titrate dobutamine to keep systolic BP is greater than 90 mm Hg.


ANS: B

The patient’s elevated PAWP indicates volume excess in relation to cardiac pumping ability,

consistent with cardiogenic shock. A saline infusion at 250 mL/hr will exacerbate the volume

excess. The other actions will help to improve cardiac output, which should lower the PAWP

and may raise the BP.

3. A patient with massive trauma and possible spinal cord injury is admitted to the emergency

department (ED). Which assessment finding by the nurse will help confirm a diagnosis of

neurogenic shock?

a. Inspiratory crackles c. Cool, clammy extremities

b. Heart rate 45 beats/min d. Temperature 101.2°F (38.4°C)


ANS: B

Neurogenic shock is characterized by hypotension and bradycardia. The other findings would

be more consistent with other types of shock.
