Question

Which of the following agents is least likely to be responsible for anaphylaxis during surgery?

1) Isosulfan blue 1
2) Anesthetic agents
3) Latex
4) Antibiotics

Answer 1

Epinephrine is the drug used to counteract the effects of anaphylactic shock, as it raises blood pressure and relaxes bronchial muscles.

Step-by-step explanation:

An anaphylactic shock is a severe allergic reaction that can be potentially fatal if left untreated. The correct drug used to counteract the effects of anaphylactic shock is epinephrine.

Epinephrine works by raising blood pressure and relaxing bronchial smooth muscle, which helps to alleviate the life-threatening symptoms of anaphylaxis. In contrast, antihistamines are generally used to treat mild allergies and are not effective in treating severe reactions such as anaphylactic shock.
