The nurse is administering norepinephrine (Levophed) to a client in shock. What is the most appropriate rationale for administering this medication?
 
  1. To produce vasoconstriction
  2. To cause bradycardia and reserve heart function
  3. To increase urine output
  4. To cause the heart's conduction system to work more effectively

Question 2

A client has not responded to IV fluids to raise blood pressure for acute shock. Which medication does the nurse anticipate will be ordered?
 
  1. Whole blood
  2. Additional crystalloids
  3. Vasodilators
  4. Vasopressors

Answer to Question 1

1

Rationale 1:Norepinephrine (Levophed) activates alpha and beta1 adrenergic receptors causing profound vasoconstriction.
Rationale 2:Norepinephrine (Levophed) activates alpha and beta1 adrenergic receptors causing increased blood pressure, force of contraction, and cardiac output.
Rationale 3:Norepinephrine (Levophed) does not increase urine output.
Rationale 4:Antidysrhythmics are not used to treat shock.

Global Rationale: The body's ability to compensate during shock is limited, so vasoconstrictors are used to maintain blood pressure. Norepinephrine (Levophed) activates alpha and beta1 adrenergic receptors causing an increase of blood pressure, force of contraction, and cardiac output.

Answer to Question 2

4

Rationale 1:Blood products, such as whole blood, are usually given as components, if the client were hemorrhaging.
Rationale 2: Additional crystalloids is incorrect because the client did not respond to IV fluids, and a vasopressor will be given.
Rationale 3: Vasodilators would further lower blood pressure.
Rationale 4:Vasopressors are needed to help stabilize blood pressure.

Global Rationale: The body's ability to compensate is limited, and profound hypotension can develop as shock progresses. In severe cases, vasoconstrictors, also called vasopressors, might be needed to help stabilize blood pressure. Because of the potential for serious adverse effects and potential organ damage due to the rapid and intense vasoconstriction, vasopressors are used only after fluid infusions have failed to raise blood pressure.
