How is Push-Dose Epinephrine prepared for adult neurogenic shock?

• A. 1 ml of 1:100,000 Epi in 9 ml Normal Saline
• B. 0.1 ml of 1:10,000 Epi in 9 ml Normal Saline
• C. 1 ml of 1:10,000 Epi in 9 ml Normal Saline
• D. 1 ml of 1:1,000 Epi in 9 ml Normal Saline

Answer: (C)

Push-dose epinephrine is prepared to deliver a small, titratable bolus that can rapidly raise blood pressure in neurogenic shock. The standard approach is to take 1 mL of epinephrine 1:10,000 (0.1 mg/mL) and dilute it with 9 mL of normal saline. This yields 10 mL of final solution at a concentration of 1:100,000 (0.01 mg/mL). Each 1 mL dose of this diluted solution contains 10 micrograms of epinephrine, which is the typical push-dose amount that clinicians titrate to effect. This balance provides a quick, controllable pressor effect without delivering a dangerously large dose at once. Using a lighter dilution, such as 1 mL of 1:10,000 into 9 mL saline but then delivering only 1 mL as a dose, would still give 10 micrograms, but the broader practice assumes the 1 mL bolus as the standard unit. Diluting with 1:1,000 would produce a much higher concentration (about 100 micrograms per mL), risking overdosage, while using 1:100,000 without proper dilution would deliver too small a bolus if a 1 mL dose is given. The chosen preparation yields a reliable, effective dose per bolus that clinicians can readily titrate.
