If a patient has an allergic reaction to a barbiturate, what is the recommended treatment?

• A. Epinephrine
• B. Diphenhydramine
• C. Send to ER
• D. Hydrocortisone

Answer: (B)

The recommended treatment for a patient experiencing an allergic reaction to a barbiturate is diphenhydramine. Diphenhydramine is an antihistamine that is effective in alleviating symptoms associated with allergic reactions, such as itching, hives, and other mild to moderate reactions. It works by blocking the action of histamine, which is released during an allergic response, thereby helping to relieve the discomfort caused by this reaction.

In cases of minor allergic reactions, administering diphenhydramine can be sufficient to manage symptoms and improve the patient's comfort. It can also be useful in premedicating patients who have a history of allergies to prevent future reactions.

In terms of other options, while epinephrine is critical in cases of severe allergic reactions such as anaphylaxis, it is not routinely used for mild allergic reactions unless there is a significant risk of airway compromise or cardiovascular collapse. Sending a patient to the emergency room might be warranted if the reaction is severe or if the patient is experiencing life-threatening symptoms, but for mild allergic reactions, diphenhydramine is often enough. Hydrocortisone, a corticosteroid, may be used for more severe inflammatory reactions, but it's not the first-line treatment for immediate allergic symptoms. Thus
