Final answer:
Option D. The nurse should prioritize assessing vital signs, stopping the infusion, and contacting the health care provider when a client develops urticaria after a secondary infusion of piperacillin.
Step-by-step explanation:
The nurse should implement the interventions in the following order of priority:
- Assess vital signs: This is the highest priority as it helps the nurse determine the client's current condition and monitor for any signs of worsening allergic reaction.
- Stop the infusion: Stopping the infusion of piperacillin is important to prevent further exposure to the allergen and minimize the client's symptoms.
- Contact the health care provider: Contacting the health care provider is necessary to inform them about the client's allergic reaction and seek further guidance on appropriate treatment.
- Document reaction to the drug: Documenting the client's reaction is important for accurate record-keeping and future reference.
- Initiate an adverse event report: Initiating an adverse event report helps ensure that the appropriate authorities are notified of the client's reaction and can take appropriate actions.
