Answer to Question 1

Correct Answer: 1,2,3
Rationale 1: The primary indication for norepinephrine is acute shock.
Rationale 2: The primary indication for norepinephrine is cardiac arrest.
Rationale 3: Norepinephrine is the vasopressor of choice for septic shock.
Rationale 4: Dopamine is the medication of choice for hypovolemic shock.
Rationale 5: Dopamine is the medication of choice for cardiogenic shock.

Answer to Question 2

Correct Answer: 4
Rationale 1: Vasoconstrictors do not cause increased blood flow.
Rationale 2: These drugs can decrease heart rate with inotropic effect.
Rationale 3: Vasoconstrictors do not decrease cardiac output. They can help with inotropic effect.
Rationale 4: Vasoconstrictors such as norepinephrine produce vasoconstriction of the vessels, thereby increasing blood pressure.
