Epinephrine is indicated for patients with an allergic reaction when:
A
they have a low-grade fever following exposure to an allergen.
B
they have a mild rash with no other symptoms.
C
they report only mild itching without any respiratory or circulatory symptoms.
D
they exhibit signs of airway compromise, such as difficulty breathing or swelling of the throat.
Verified step by step guidance1
Understand the role of epinephrine: Epinephrine is a medication used to treat severe allergic reactions (anaphylaxis). It works by relaxing the muscles in the airways and tightening blood vessels to counteract the symptoms of anaphylaxis.
Identify the symptoms of anaphylaxis: These include difficulty breathing, swelling of the throat or tongue, rapid drop in blood pressure, hives, and other severe symptoms that indicate airway compromise or circulatory failure.
Evaluate the scenarios provided: A low-grade fever, mild rash, or mild itching without respiratory or circulatory symptoms do not indicate anaphylaxis. These symptoms are not severe enough to warrant the use of epinephrine.
Recognize the correct indication for epinephrine: The medication is indicated when there are signs of airway compromise, such as difficulty breathing or swelling of the throat, as these are life-threatening symptoms of anaphylaxis.
Conclude that epinephrine should only be administered in cases of severe allergic reactions with airway or circulatory compromise, not for mild or non-life-threatening symptoms.
