A nurse is conducting medication reconciliation and needs to match each drug to its appropriate drug class to ensure safe administration and monitor for potential interactions. Which of the following drug and drug class pairings are correct?

This question focuses on emergency management of drug-induced anaphylaxis. It requires identifying the most urgent nursing action to stop the delivery of the offending antigen, which is the necessary first step to mitigate the severity of the systemic, life-threatening allergic reaction being experienced.

Choice A rationale

While providing oxygen and breathing support is a critical component of managing anaphylaxis, stopping the source of the allergen takes absolute priority to prevent further progression of the reaction, ensuring that no more of the triggering medication enters the system.

Choice B rationale

In the event of an anaphylactic reaction, stopping the infusion of the suspected medication is the immediate, non-negotiable priority. This action prevents further antigen-antibody interaction, which is the fundamental driver of the systemic release of histamine and inflammatory mediators.

Choice C rationale

Administering epinephrine is the definitive treatment for anaphylaxis and is given immediately after stopping the drug. While vital for reversing symptoms, the nurse must first disconnect the infusion to prevent ongoing exposure while they prepare to administer the life-saving medication.

Choice D rationale

Calling a Rapid Response or code team is a necessary step to bring additional resources to the bedside. However, the nurse must simultaneously stop the infusion, as every second of continued medication administration increases the potential for irreversible cardiovascular or respiratory collapse.

This question evaluates the standard of practice for patient identification. It requires applying the principle of using at least two unique patient identifiers, which is the cornerstone of safe care delivery, preventing misidentification errors that can lead to life-threatening complications during medication administration.

Choice A rationale

While the ID armband is a primary source of identification, relying on it exclusively is not the best practice. The Joint Commission mandates the use of at least two patient identifiers to ensure the correct patient is receiving the correct medication.

Choice B rationale

Asking the patient to state their name and date of birth is an effective method of identification. However, this method is incomplete because it does not include the essential step of verifying this verbal information against the official medical records and the patient's armband.

Choice C rationale

Asking the patient to state only their last name is insufficient for accurate identification. Many patients may share the same last name, and this lack of specific, unique identifiers significantly increases the risk of administering medication to the wrong individual during care.

Choice D rationale

Using two unique identifiers and cross-verifying them against the patient's arm band and the medication administration record is the gold standard for safety. This multi-step process minimizes the risk of identification errors and is required by national patient safety standards for healthcare.
