The nurse is reviewing orders for a patient in anaphylactic shock.
Which medications should the nurse plan to administer first?
Epinephrine (Adrenaline).
Dexamethasone (Decadron).
0.9% Normal Saline.
Dobutamine (Dobutrex).
The Correct Answer is A
Choice A rationale
Epinephrine is the first-line treatment for anaphylactic shock. It works by constricting blood vessels to increase blood pressure, relaxing smooth muscles in the lungs to reduce wheezing and improve breathing, stimulating the heart, and reducing hives and swelling around the face and lips.
Choice B rationale
Dexamethasone is a corticosteroid that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by reducing inflammation.
Choice C rationale
0.9% Normal Saline is a type of intravenous fluid that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by increasing fluid volume in the body to help maintain blood pressure.
Choice D rationale
Dobutamine is a medication that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by stimulating the heart muscle to increase cardiac output, which can help maintain blood pressure.
