When caring for a patient in acute septic shock, the nurse would anticipate
A) Administering osmotic and/or loop diuretics.
B) Infusing large amounts of intravenous fluids.
C) Administering intravenous diphenhydramine (Benadryl).
D) Assisting with insertion of a ventricular assist device (VAD).
Septic shock is characterized by a decreased circulating blood volume. Volume expansion with the administration of intravenous fluids is the cornerstone of therapy. The administration of diuretics is inappropriate. VADs are useful for cardiogenic shock, not septic shock. Diphenhydramine (Benadryl) may be used for anaphylactic shock, but would not be helpful with septic shock.
When caring for a critically ill patient who is being mechanically ventilated, the nurse will astutely monitor for which of the following clinical manifestations of multiple organ dysfunction syndrome (MODS)?
A) Increased gastrointestinal (GI) motility
B) Increased serum albumin
C) Decreased blood urea nitrogen (BUN)/creatinine ratio
D) Decreased respiratory compliance
Clinical manifestations of MODS include symptoms of respiratory distress, signs and symptoms of decreased renal perfusion, decreased serum albumin and prealbumin, decreased GI motility, acute neurologic changes, myocardial dysfunction, disseminated intravascular coagulation (DIC), and changes in glucose metabolism.
A massive gastrointestinal bleed has resulted in hypovolemic shock in an elderly patient. Which of the following is a priority nursing diagnosis?
A) Acute pain
B) Impaired tissue integrity
C) Decreased cardiac output
D) Ineffective tissue perfusion
The many deleterious effects of shock are all related to inadequate perfusion and oxygenation of every body system. This nursing diagnosis supersedes the other diagnoses.
Which of the following laboratory findings fits with a diagnosis of cardiogenic shock?
A) Decreased liver enzymes
B) Increased white blood cells
C) Increased blood urea nitrogen and creatinine levels
D) Decreased red blood cells, hemoglobin, and hematocrit
The renal hypoperfusion that accompanies cardiogenic shock results in increased BUN and creatinine levels. Impaired perfusion of the liver results in increased liver enzymes while red blood cell indices are typically normal because of relative hypovolemia. White blood cell levels do not typically rise in cardiogenic shock.
A patient's localized infection has progressed to the point where septic shock is now suspected. Which of the following is an appropriate treatment modality for this patient?
A) Insulin infusion
B) Aggressive fluid resuscitation
C) Intravenous administration of epinephrine
D) Administration of nitrates and β-adrenergic blockers
Patients in septic shock require large amounts of fluid replacement. Nitrates and β-adrenergic blockers are most often used in the treatment of patients in cardiogenic shock. Epinephrine is indicated in anaphylactic shock, and insulin infusion is not normally necessary in the treatment of septic shock (but can be).
The nurse would recognize which of the following clinical manifestations as suggestive of sepsis?
A) Respiratory rate of seven breaths per minute
B) Hyperglycemia in the absence of diabetes
C) Sudden diuresis unrelated to drug therapy
D) Bradycardia with sudden increase in blood pressure
Hyperglycemia in patients with no history of diabetes is a diagnostic criterion for sepsis. Oliguria, not diuresis, typically accompanies sepsis along with tachycardia and tachypnea.

a. check the blood pressure.
b. obtain an oxygen saturation.
c. attach a cardiac monitor.
d. check level of consciousness.

d. sodium nitroprusside (Nipride).
B AND C
