The nurse is preparing to administer popamine (Dopastat) for a client who is experiencing cardiogenic and hypovolemic shock. Which effects does the nurse anticipate will occur? (Select all that apply.)
 
  Note: Credit will be given only if all correct choices and no incorrect choices are selected.
 
  1. Effects depend on the dose.
  2. An increase of renal blood flow
  3. An increase of cardiac output
  4. Hypotension
  5. Decreased urine output

Question 2

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

Answer to Question 1

Correct Answer: 1, 2, 3

Rationale 1: In low doses, dopamine stimulates increased blood flow to the kidneys, and at higher doses, dopamine increases the cardiac output and causes vasoconstrictionall of which make this a valuable drug when treating cardiogenic or hypovolemic shock.
Rationale 2: In low doses, dopamine stimulates increased blood flow to the kidneys, and at higher doses, dopamine increases the cardiac output and causes vasoconstrictionall of which make this a valuable drug when treating cardiogenic or hypovolemic shock.
Rationale 3: In low doses, dopamine stimulates increased blood flow to the kidneys, and at higher doses, dopamine increases the cardiac output and causes vasoconstrictionall of which make this a valuable drug when treating cardiogenic or hypovolemic shock.
Rationale 4: Hypotension is incorrect because dopamine raises blood pressure.
Rationale 5: Decreased urine output is incorrect because dopamine stimulates the kidneys.

Global Rationale: In low doses, dopamine stimulates increased blood flow to the kidneys, and at higher doses, dopamine increases the cardiac output and causes vasoconstrictionall of which make this a valuable drug when treating cardiogenic or hypovolemic shock. Hypotension is incorrect because dopamine raises blood pressure. Increased urine output is incorrect because dopamine stimulate the kidney.

Answer to Question 2

Correct Answer: 4

Rationale 1: Whole blood is incorrect because blood products are usually given as components, and would only be necessary 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 is incorrect because this type of medication would further lower blood pressure.
Rationale 4: 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.
