An older client is hospitalized following an embolic stroke resulting in right-sided paresis. Three days after admission, the nurse notes edema and erythema to the right lower leg. These findings should alert the nurse to which possible condition?

A. High doses of fish oil can indeed increase the risk of bleeding, particularly because fish oil has anticoagulant properties that can interfere with blood clotting. This risk is especially significant if the client is also taking other anticoagulant or antiplatelet medications.
B. While it is true that fish can be heart-healthy due to its omega-3 fatty acids, this statement does not fully address the concerns about the safety of high doses of fish oil supplements. Eating fish in moderate amounts is beneficial, but the focus here is on the effects of large doses of fish oil supplements, not just consuming fish. The safety of high doses should be considered separately.
C. Encouraging the client to increase the dose of fish oil is not appropriate without considering potential side effects and risks. High doses of fish oil can lead to gastrointestinal symptoms like nausea, diarrhea, and indigestion.
D. Not all types of oils increase cholesterol and triglycerides. For instance, omega-3 fatty acids found in fish oil can actually help lower triglyceride levels and may have a positive effect on cholesterol levels.

A. Infection in the lower leg could cause localized redness, swelling, warmth, and possibly pain. However, the presence of these symptoms alone is not as specific to infection, especially without additional symptoms like fever or purulent discharge.
B. Deep vein thrombosis is a condition where a blood clot forms in a deep vein, commonly in the legs. The symptoms of DVT include swelling (edema), redness (erythema), warmth, and sometimes pain in the affected leg. Given that the client has paresis on one side and is likely less mobile, the risk of DVT increases.
C. A pulmonary embolism occurs when a blood clot (often from the legs) travels to the lungs and causes a blockage. While a pulmonary embolism is a serious complication of DVT, the findings of localized edema and erythema in the leg are more directly associated with DVT itself rather than the secondary complication of a pulmonary embolism.
D. Fat emboli typically occur after fractures or trauma and lead to fat droplets entering the bloodstream and causing blockages in the lungs, brain, or skin. The classic symptoms include respiratory distress, neurological symptoms, and petechial rash.
