A nurse is caring for a postpartum patient who is at risk for developing DVT.

Which of the following interventions should the nurse implement to prevent DVT? (Select all that apply.).

These are the interventions that can help prevent DVT by keeping the blood flowing and preventing clot formation.

Choice D is wrong because massaging the affected limb can dislodge a clot and cause a PE.Choice E is wrong because elevating the affected limb can reduce blood flow and increase the risk of DVT.

Normal ranges for DVT prevention vary depending on the individual risk factors and clinical situation, but some general recommendations are:

• Encourage early and frequent ambulation as soon as possible after delivery.

• Apply anti-embolism stockings or intermittent pneumatic compression devices during hospital stay and until fully mobile.

• Administer prophylactic anticoagulant medication as prescribed, usually for 6 to 12 weeks postpartum or longer if high risk.The type and dose of anticoagulant may depend on the patient’s weight, renal function, breastfeeding status and preference.

Spinach.The nurse should instruct the client to avoid fluctuations in the amount and frequency of consumption of foods that are rich in vitamin K, such as spinach, because they can make warfarin less effective.Vitamin K is involved in blood clotting and can counteract the anticoagulant effect of warfarin.

Grapefruit is wrong because grapefruit can increase the risk of bleeding by affecting warfarin metabolism or pharmacodynamics.Grapefruit can inhibit the enzyme CYP3A4 that metabolizes warfarin and increase its blood levels.

Cheese is wrong because cheese does not have a significant interaction with warfarin.However, some types of cheese, such as mature cheese and blue cheese, contain small amounts of vitamin K and should be consumed consistently.

Eggs is wrong because eggs do not have a significant interaction with warfarin.However, egg yolks contain some vitamin K and should be consumed consistently.
