After an intramuscular injection of penicillin, a patient develops severe difficulty breathing and a swollen tongue. Which medication should the nurse prepare to administer?
Dopamine
Epinephrine
Norepinephrine
Pseudoephedrine
The Correct Answer is B
Choice A rationale: Dopamine is not the appropriate medication for an allergic reaction. It is a neurotransmitter and is not used in the treatment of anaphylaxis.
Choice B rationale: Epinephrine is the first-line treatment for anaphylaxis, including severe difficulty breathing and swelling of the tongue. It acts quickly to reverse the symptoms of an allergic reaction.
Choice C rationale: Norepinephrine is not the medication of choice for an allergic reaction. It primarily acts as a vasoconstrictor and is used in conditions like septic shock.
Choice D rationale: Pseudoephedrine is a decongestant and is not the appropriate medication for treating an allergic reaction with respiratory distress.
