  1. Urinary output of at least 50 mL/hour
   2. Increased cardiac output
   3. Vasoconstriction and increased blood pressure
   4. Stabilization of fluid loss

Question 2

  1. Cancer
   2. Flu
   3. Tuberculosis
   4. Smallpox

Answer to Question 1

1. Urinary output of at least 50 mL/hour

Rationale:
At low doses, dopamine stimulates dopaminergic receptors, especially in the kidneys, leading to vasodilation and an increased blood flow through the kidneys. Increased cardiac output occurs with high, not low, doses of dopamine when beta1-adrenergic receptors are stimulated. Vasoconstriction and increased blood pressure occurs with high, not low, doses of dopamine when alpha-adrenergic receptors are stimulated. Dopamine does not prevent or stabilize fluid loss.

Answer to Question 2

4. Smallpox

Rationale:
Smallpox, anthrax, botulism, plague, viral hemorrhagic fevers, and tularemia are the agents that are of highest concern in regard to bioterrorism. Cancer, flu, and tuberculosis have not been developed into biological threats and would not kill the number of people that smallpox would.
