Pharmacological and Parenteral TherapiesQuestion 462 of 2368

Before giving the first dose of a new antimicrobial, the nurse learns that the client had an allergic reaction to a different class of antimicrobial. What should the nurse do?

  1. Give the drug because it belongs to a different antimicrobial class
  2. Give the drug and monitor the client closely for a new rash
  3. Tell the prescribing provider about the allergy before giving the drug
  4. Ask the client to sign a consent form and then give the drug
Show answer

Correct answer: Tell the prescribing provider about the allergy before giving the drug

Cross-reactivity can occur between classes, so the provider must know before the medication is given.
