Question

Quizplus · Accepted Answer

Epinephrine is the first-line treatment for anaphylactic shock and is effective in improving hypotension by causing vasoconstriction and increasing cardiac output. Diphenhydramine is an antihistamine and is used primarily for treating allergic symptoms such as itching and hives but does not improve hypotension. Hydrocortisone is a steroid and may be used in combination with epinephrine to prevent a secondary reaction but does not address hypotension directly. Oxygen is important for maintaining adequate oxygenation but does not directly improve hypotension.
