A flight nurse is managing a patient in septic shock during transport. Initial fluid resuscitation has been performed, but the patient remains hypotensive. Which vasopressor should be administered as the first-line treatment to increase blood pressure?
Norepinephrine
Phenylephrine
Dopamine
Vasopressin
Norepinephrine is considered the first-line vasopressor for septic shock due to its strong alpha-adrenergic effects, which increase vascular tone and blood pressure. Dopamine is less preferred because it can lead to arrhythmias and has variable effects depending on the dose, making it less reliable for managing septic shock. Phenylephrine and vasopressin are generally not considered first-line treatments for septic shock.
