Question
A client develops wheezing, generalized hives, and blood pressure 78/42 mm Hg after receiving an antibiotic. Which medication should the nurse prepare to administer first?
1Oral diphenhydramine
2Intramuscular epinephrine✓ Correct answer
3Inhaled corticosteroid
4Oral acetaminophen
Explanation
Wheezing, hives, and hypotension after antibiotic exposure indicate anaphylaxis. Intramuscular epinephrine is the first-line medication because it supports airway, breathing, and circulation. Antihistamines or corticosteroids may be adjuncts but do not replace epinephrine for life-threatening anaphylaxis.
In-depth explanation
Clinical Judgment Recognize multi-system allergic reaction with hypotension as anaphylaxis and treat ABCs first.
Memory Tip Anaphylaxis equals epinephrine first.
KR vs US NCLEX distinguishes adjunct allergy medications from first-line emergency epinephrine.
Clinical scenario
Clinical Practice Guide Anaphylaxis with respiratory compromise or hypotension requires immediate epinephrine and emergency support.
Caution Do not delay epinephrine while waiting to see whether symptoms improve.
Key concepts
Anaphylaxis — A severe systemic allergic reaction that may cause airway swelling, bronchospasm, hypotension, and shock.
Epinephrine — First-line medication for anaphylaxis that improves airway tone, bronchodilation, and blood pressure.
Hypotension — Low blood pressure that can indicate shock and inadequate organ perfusion.
