A nurse suspects a medication error in a client who recently started a new medication. Which of the following assessments would support this suspicion?

An allergic reaction to a newly administered medication can be a strong indicator of a medication error. It suggests that the client may have received a medication to which they are allergic or that they were given an incorrect dose or formulation of the medication. Allergic reactions require immediate intervention to prevent further harm.

Incorrect choices:

a) The client reports mild constipation: Mild constipation is a non-specific symptom that may or may not be related to a medication error. It can occur for various reasons, including dietary changes or side effects of the medication.

b) The client's blood pressure remains within normal limits: Blood pressure within normal limits does not necessarily indicate or rule out a medication error. It is important to assess for other specific signs and symptoms related to the medication.

d) The client exhibits improved mood and increased energy: Improved mood and increased energy are positive outcomes that may occur with the appropriate use of medication. They do not suggest a medication error unless accompanied by other concerning signs or symptoms.

A) This is correct because stopping the infusion and notifying the provider are the priority actions for a client who is experiencing signs and symptoms of anaphylaxis, which is a life-threatening allergic reaction to a medication. The nurse should also prepare to administer epinephrine as prescribed.

B) This is incorrect because administering diphenhydramine as prescribed is not the first action for a client who is experiencing anaphylaxis. Diphenhydramine is an antihistamine that can help relieve some symptoms of an allergic reaction, but it is not effective for reversing bronchoconstriction or hypotension that may occur in anaphylaxis.

C) This is incorrect because monitoring the client's vital signs and oxygen saturation is not the first action for a client who is experiencing anaphylaxis. Although these are important assessments, they are not as urgent as stopping the infusion and notifying the provider.

D) This is incorrect because slowing down the infusion rate and observing for improvement are not appropriate actions for a client who is experiencing anaphylaxis. Slowing down or continuing the infusion may worsen the client's condition and delay treatment.
