Which client is most likely to require further assessment when prescribed anticoagulant therapy?

The elderly client on multiple medications is the most likely candidate to require further assessment when prescribed anticoagulant therapy due to several key factors. As people age, they often experience changes in drug metabolism and excretion, which can lead to an increased risk of adverse effects or drug interactions. The presence of multiple medications raises the concern for potential interactions with anticoagulants that could increase the risk of bleeding or diminish the effectiveness of the therapy.

Additionally, the elderly population is generally more prone to complications related to anticoagulant therapy, such as hemorrhage, due to age-related physiological changes. Therefore, thorough assessment is necessary to evaluate kidney and liver function, understand the patient's complete medication regimen, and ensure careful monitoring and education about potential side effects and what to watch for.

Other clients listed, while they may have their own unique considerations, do not present as significant a red flag as the elderly client on multiple medications, making additional assessment particularly critical in that context.
