A nurse is reinforcing teaching with a client who has a new prescription for epinephrine auto-injector PRN. The nurse should reinforce with the client that the medication can help treat which of the following manifestations?

Epinephrine is a medication that belongs to a class of drugs called adrenergic agonists. It works by stimulating certain receptors in the body, particularly alpha and beta adrenergic receptors. One of the effects of epinephrine is vasoconstriction, which can help reduce swelling and inflammation. Swelling of the lips, also known as angioedema, can occur as an allergic reaction to certain substances, such as foods, medications, or insect bites. Epinephrine acts as an immediate treatment for severe allergic reactions, including angioedema, by constricting blood vessels and reducing swelling. The other manifestations mentioned, such as hyperglycemia (high blood sugar), hand tremors, and nausea, are not typically treated with epinephrine. Epinephrine's primary role is to address severe allergic reactions, anaphylaxis, or potentially life-threatening conditions associated with allergic responses
