A nurse is obtaining a medical history from a client who has a new diagnosis of type 2 diabetes mellitus. The nurse should report which of the following conditions is a contraindication for the use of metformin?

A. Discuss the incident with the health care worker: While addressing the suspected impairment with the worker is important, immediate removal from the work environment takes priority to ensure patient safety and prevent potential harm. Confrontation can follow after securing a safe environment.

B. Document the findings of the incident: Documentation is essential for legal and professional accountability, but it is secondary to protecting patients from immediate risk. Recording observations does not prevent ongoing exposure to unsafe practice.

C. Remove the health care worker from the work environment: The first priority is ensuring patient safety. Suspected chemical impairment can impair judgment, coordination, and response time, creating a high risk for errors or accidents. Immediate removal prevents potential harm to clients and coworkers.

D. Place the health care worker on probation: Probation is a disciplinary measure that may follow an investigation, but it is not the first step. Immediate action must focus on safety, and probation does not address the urgent risk posed by active impairment.

A. Outer posterior aspect of upper arm: This site, the deltoid muscle, is appropriate for small-volume IM injections (up to 1 mL). However, it is limited by muscle size and is not preferred for larger volume or more irritating medications.

B. Upper thigh: The vastus lateralis muscle of the anterior thigh is a common IM site, particularly in infants and young children. While suitable, it may be less preferred in adults unless other sites are contraindicated.

C. Abdomen: The abdomen is not used for intramuscular injections; it is a common site for subcutaneous injections, such as insulin or heparin. Administering an IM injection in the abdomen would risk improper absorption and injury.

D. Ventrogluteal: The ventrogluteal site is preferred for intramuscular injections in adults because it is away from major nerves and blood vessels, allows for larger volumes of medication, and has a consistent muscle mass. It minimizes the risk of complications and is considered the safest IM injection site.
