A nurse is caring for a client who is 7 days postpartum and calls the clinic to report pain and redness of her left calf. Besides seeing her provider, which of the following interventions should the nurse suggest?

A. Flex her knee while resting: Bending or flexing the knee can increase venous pressure and potentially worsen a thrombus if a deep vein thrombosis (DVT) is present. This is not recommended until the client is evaluated by a healthcare provider. B. Elevate her leg: Elevating the affected leg helps reduce swelling and promotes venous return, which can alleviate discomfort. This is a safe supportive measure while awaiting medical evaluation for possible DVT. C. Apply cold compresses: Cold compresses are typically used for acute inflammation or localized injury, but in suspected DVT, cold therapy does not provide therapeutic benefit and may delay appropriate treatment. D. Massage the area: Massaging a leg with suspected DVT is contraindicated because it can dislodge a thrombus, increasing the risk of pulmonary embolism. This intervention should be avoided entirely until medical assessment.
