Who among the following clients is most likely to have an increased risk of thrombophlebitis and stroke?

The client receiving advanced cancer treatment is most likely to have an increased risk of thrombophlebitis and stroke. Advanced cancer treatments often involve aggressive therapies, such as chemotherapy or immunotherapy, which can lead to various complications. These complications may include increased blood clotting tendencies due to the cancer itself or as a side effect of certain medications used in treatment.

Cancer can create a prothrombotic state, which means there is an increased propensity for blood clot formation. This situation may be exacerbated in advanced cases due to factors like immobility during intensive treatments, the presence of central venous catheters, or the underlying cancer causing changes in the blood's coagulation factors. Therefore, the combination of advanced disease and intensive treatment contributes significantly to elevating the risk for thrombophlebitis and stroke.

Other clients, such as those with early-stage cancer, undergoing radiation therapy, or in remission, may have lower risks related to these conditions. Early-stage cancer may not present the same level of risk as advanced cancer, while clients in remission generally have a reduced disease burden, making complications less likely. Thus, the client undergoing advanced cancer treatment is the one with the highest risk in this context.
