Causes and risk factors ( 7 Questions)
A client is admitted to the emergency department with signs of anaphylaxis after being stung by a bee. The nurse should expect to administer which of the following medications first?
Epinephrine is the first-line medication for anaphylaxis, which is a severe allergic reaction that can cause bronchoconstriction, hypotension, and shock. Epinephrine acts as a bronchodilator and a vasoconstrictor, reversing the effects of histamine and other mediators released during anaphylaxis.
is incorrect because diphenhydramine is an antihistamine that can help relieve itching, hives, and urticaria, but it does not reverse bronchoconstriction or hypotension. Diphenhydramine can be given as an adjunct therapy after epinephrine.
is incorrect because albuterol is a beta2 agonist that can help relieve bronchospasm, but it does not affect blood pressure or other systemic effects of anaphylaxis. Albuterol can be given as an adjunct therapy after epinephrine.
is incorrect because hydrocortisone is a corticosteroid that can help reduce inflammation and prevent delayed reactions, but it does not have an immediate effect on anaphylaxis. Hydrocortisone can be given as an adjunct therapy after epinephrine.
