Which client history would prompt a nurse to contact a registered nurse when megestrol acetate is prescribed?

When megestrol acetate is prescribed, a history of thrombophlebitis warrants immediate communication with a registered nurse due to the risks associated with the medication. Megestrol acetate is a progestin used primarily in managing anorexia or weight loss in various health conditions. However, it has notable side effects that can contribute to thromboembolic events, as it may increase the risk of blood clots.

Individuals with a history of thrombophlebitis already have underlying issues related to blood flow, and introducing a medication that potentially exacerbates clotting risks can lead to severe complications. This condition directly relates to thrombus formation, so careful monitoring and assessment are crucial when this medication is initiated in such patients.

While other conditions like gout, asthma, or a history of myocardial infarction might also require consideration and monitoring, they do not present the same immediate concern regarding the increased risk of thrombosis associated with megestrol acetate. Thus, proximity to vascular complications makes thrombophlebitis a critical factor necessitating further assessment and possibly intervention from a registered nurse.
