Question

The effects of epinephrine are typically observed within _________ following administration.

1) 30 seconds
2) 1 minute
3) 30 minutes
4) 1 hour

Answer 1

The effects of epinephrine are often observed within 1 minute following administration, rapidly counteracting symptoms of anaphylaxis such as low blood pressure and bronchial constriction.

Step-by-step explanation:

The effects of epinephrine are typically observed within 1 minute following administration. Epinephrine, also known as adrenaline, is a catecholamine hormone secreted by the adrenal medulla in response to short-term stress such as an anaphylactic reaction to allergens. The rapid action of epinephrine upon administration is vital for raising blood pressure and relaxing bronchial smooth muscle, which can be lifesaving in cases of severe allergies causing anaphylactic shock.
