Which federal regulation provides guidelines for managing government credit cards?

The Government Charge Card Abuse Prevention Act is the correct choice as it specifically addresses the management and oversight of government-issued credit cards. This legislation was enacted to reduce the risks associated with the misuse of government charge cards and to ensure proper use through established guidelines and controls. The act outlines the responsibilities of federal agencies in managing these cards, including the development of internal controls and oversight measures aimed at preventing fraud, waste, and abuse.

In contrast, the other options do not directly pertain to the management of government credit cards. The Federal Credit Card Management Act, while it may sound relevant, is not a recognized piece of legislation focused on government credit card management. The Government Procurement Act focuses on the broader context of procurement processes rather than specific credit card use, and the Public Financial Management Act is concerned with the overall financial management of federal funds but does not specifically regulate government credit card usage.
