A patient with severe hypotension from septic shock remains unstable after appropriate intravenous fluid resuscitation. Which vasoactive medicine is generally used as the first-line vasopressor?
Correct answer: A. Norepinephrine
- A. Norepinephrine
- B. Isosorbide dinitrate
- C. Furosemide
- D. Propranolol
Explanation
Norepinephrine produces mainly alpha-adrenergic vasoconstriction and supports vascular tone in persistent septic shock. Isosorbide dinitrate and furosemide can reduce effective circulation, while propranolol can worsen hypotension and bradycardia.
