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 incorrect because discarding the vial and obtaining a new one is not necessary actions for a vial of insulin that has a small amount of white precipitate at the bottom. This precipitate indicates that the insulin has crystallized due to cold storage or temperature changes, but it can be resuspended by gently rolling or rotating the vial.

B) This is incorrect because shaking the vial vigorously until the precipitate dissolves is not an appropriate action for a vial of insulin that has a small amount of white precipitate at the bottom. Shaking the vial may cause air bubbles or froth to form, which can affect the accuracy of the dose measurement and administration.

C) This is incorrect because warming the vial in a microwave oven for a few seconds is not a safe action for a vial of insulin that has a small amount of white precipitate at the bottom. Warming the vial in a microwave oven may cause uneven heating or damage to the insulin molecules, which can alter the potency and effectiveness of the medication.

D) This is correct because rolling the vial gently between the palms of both hands is the recommended action for a vial of insulin that has a small amount of white precipitate at the bottom. Rolling the vial gently helps to resuspend the insulin crystals and restore the uniform appearance of the solution.
