A nurse is preparing to administer insulin to a client who has diabetes mellitus. The nurse notices that the insulin vial has a small amount of white precipitate at the bottom. Which of the following actions should the nurse take?

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.

Rapid heart rate and palpitations are potential signs of a medication error, particularly if the client is receiving medication that can affect cardiac function. These symptoms can indicate an adverse reaction or an overdose of certain medications, such as those that affect the cardiovascular system. Monitoring the client's cardiac status is crucial in detecting and managing potential medication errors.

Incorrect choices:

a) Mild headache and dizziness: While these symptoms may be bothersome, they are generally not indicative of a medication error unless they persist or worsen.

b) Temporary nausea and vomiting: Nausea and vomiting can occur as side effects of medications, and they may not necessarily indicate a medication error.

d) Transient muscle weakness and fatigue: Although muscle weakness and fatigue can be associated with medication errors, they are less specific and may be caused by various other factors. Rapid heart rate and palpitations are more concerning in this context.
