A patient develops hypotension, laryngeal edema, and bronchospasm after eating peanuts. Which medication should the nurse prepare to administer?
- A. Promethazine
- B. Epinephrine
- C. Diphenhydramine
- D. Hydroxyzine
Correct Answer: B
Rationale: The patient is exhibiting symptoms of anaphylaxis triggered by a peanut allergy, which is a severe and potentially life-threatening allergic reaction. The appropriate medication for anaphylaxis is epinephrine. Epinephrine acts quickly to reverse the symptoms by constricting blood vessels, relaxing bronchial muscles, and reducing laryngeal edema, making it the drug of choice for this situation. Promethazine, diphenhydramine, and hydroxyzine are not the first-line treatments for anaphylaxis and may not address the severe manifestations seen in this case.
