A nurse is assessing an obese client in the clinic for follow-up after an episode of deep vein thrombosis.The client has lost 20 lb (9.09 Kg) since the last visit.
What action by the nurse is best?

Choice A rationale

The nurse must first determine the nature of the client's weight loss. Unintentional weight loss can be a sign of underlying pathology, such as malignancy, endocrine disorders, or psychological conditions. Intentional weight loss, however, could indicate a positive lifestyle change. The nurse's initial action is to differentiate between these two possibilities to guide further assessment and intervention.

Choice B rationale

While a high-protein, high-fiber diet is generally healthy and can aid in weight management, encouraging it prematurely without understanding the cause of the weight loss is not the best initial action. The client may already be on a restrictive or specific diet, and the nurse needs to assess their current nutritional status and dietary habits before making recommendations.

Choice C rationale

Measuring for new compression stockings may be necessary eventually if the client's leg measurements have changed significantly due to weight loss. However, this is a procedural task and not the most crucial initial assessment. The priority is to understand the cause of the weight loss, as this has broader implications for the client's health status and care plan.

Choice D rationale

A 3-day food recall diary is a useful tool for assessing dietary intake, but it is a secondary action. The most important initial step is to determine if the weight loss was intentional or not. This information will dictate whether a dietary assessment is the most appropriate next step or if a more comprehensive medical workup is needed.
