NurseDive Free Nursing Practice Question
A nurse is caring for a patient who has been prescribed enoxaparin (Lovenox) subcutaneously for prophylaxis against deep vein thrombosis (DVT). The nurse should instruct the patient to:
A. Avoid foods that are high in vitamin K.
Avoid foods that are high in vitamin K is wrong because vitamin K interacts with warfarin, another anticoagulant, but not with enoxaparin.Vitamin K helps the blood clot, so patients who take warfarin should avoid foods that are high in vitamin K, such as leafy green vegetables, broccoli, or liver.
B. Administer injections into areas with decreased subcutaneous tissue.
Administer injections into areas with decreased subcutaneous tissue is wrong because enoxaparin should be injected into areas with adequate subcutaneous tissue, such as the abdomen or the thighs.Injecting into areas with decreased subcutaneous tissue can cause bruising, pain, or hematoma formation.
C. Massage injection sites after administration.
Massage injection sites after administration is wrong because massaging the injection sites can cause bleeding, bruising, or irritation.Patients who take enoxaparin should not rub or press on the injection sites after administration.
D. Use a soft-bristled toothbrush.
This is because enoxaparin (Lovenox) is an anticoagulant that prevents blood clots by thinning the blood.Therefore, patients who take enoxaparin should avoid activities that can cause bleeding, such as using a hard-bristled toothbrush, flossing, shaving, or cutting their nails.

Similar Questions
A client has been prescribed warfarin (Coumadin) for treatment of deep vein thrombosis (DVT). Which of the following instructions should the nurse include in patient teaching? Select all that apply.
A. Avoid foods that are high in vitamin K.
Vitamin K is needed for the production of some clotting factors in the liver. Warfarin blocks the action of vitamin K, and thus reduces the clotting ability of the blood. However, if the intake of vitamin K varies significantly from day to day, it can affect the stability of the warfarin effect.Foods that are high in vitamin K include green leafy vegetables, such as spinach, kale, broccoli, cabbage, and lettuce, as well as some vegetable oils, such as soybean and canola.Patients should not avoid these foods completely, but they should keep their intake consistent and inform their doctor or pharmacist if they make any changes to their diet.
B. Take aspirin for pain relief.
Aspirin is a medication that also prevents blood clots by inhibiting platelets, which are cells that stick together to form clots.Taking aspirin with warfarin can increase the risk of bleeding significantly and is not recommended unless prescribed by a doctor for a specific reason.Patients should avoid taking aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, for pain relief unless advised by their doctor.They should also check the labels of any over-the-counter medications or supplements they use and avoid those that contain aspirin or NSAIDs.
C. Report any unusual bleeding to healthcare provider.
Warfarin can increase the risk of bleeding, especially if the dose is too high or if it interacts with other medications or supplements.Patients should notify their doctor or seek emergency care if they have any signs of bleeding, such as bruising, red or black stools, blood in the urine, coughing up blood, vomiting blood, nosebleeds, heavy menstrual bleeding, headaches, dizziness, weakness, or swelling.They should also inform their doctor of any other medications or supplements they are taking, including over-the-counter products and herbal remedies.
D. Use an electric razor when shaving.
Warfarin can make the skin more prone to bleeding from minor cuts or injuries. Patients should use an electric razor when shaving to reduce the risk of nicking themselves and causing bleeding.They should also use a soft toothbrush and avoid flossing if it causes bleeding.They should wear gloves when handling sharp objects or working in the garden.
E. Wear shoes that fit well and avoid tight clothing.
This instruction is not related to warfarin therapy and does not affect its efficacy or safety. However, it may be a general advice for patients with DVT to prevent further complications or discomfort.Wearing shoes that fit well and avoiding tight clothing can help improve blood circulation in the legs and prevent swelling or pain.Patients with DVT should also elevate their legs when possible and wear compression stockings if prescribed by their doctor.
Full Explanation
Warfarin (Coumadin) is a blood thinner that prevents blood clots from forming or growing larger.
It is used to treat or prevent deep vein thrombosis (DVT), a condition in which a blood clot forms in a vein deep in the body, usually in the legs.
It can also prevent pulmonary embolism (PE), a condition in which a blood clot breaks off and travels to the lungs, blocking blood flow and causing breathing problems.
Patients taking warfarin should follow these instructions:
• Avoid foods that are high in vitamin K.
Vitamin K is needed for the production of some clotting factors in the liver.
Warfarin blocks the action of vitamin K, and thus reduces the clotting ability of the blood.
However, if the intake of vitamin K varies significantly from day to day, it can affect the stability of the warfarin effect. Foods that are high in vitamin K include green leafy vegetables, such as spinach, kale, broccoli, cabbage, and lettuce, as well as some vegetable oils, such as soybean and canola. Patients should not avoid these foods completely, but they should keep their intake consistent and inform their doctor or pharmacist if they make any changes to their diet.

Patients should use an electric razor when shaving to reduce the risk of nicking themselves and causing bleeding. They should also use a soft toothbrush and avoid flossing if it causes bleeding. They should wear gloves when handling sharp objects or working in the garden.
Choice B and E are wrong because:
• Take aspirin for pain relief.
Aspirin is a medication that also prevents blood clots by inhibiting platelets, which are cells that stick together to form clots. Taking aspirin with warfarin can increase the risk of bleeding significantly and is not recommended unless prescribed by a doctor for a specific reason. Patients should avoid taking aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, for pain relief unless advised by their doctor. They should also check the labels of any over-the-counter medications or supplements they use and avoid those that contain aspirin or NSAIDs.
• Wear shoes that fit well and avoid tight clothing.
This instruction is not related to warfarin therapy and does not affect its efficacy or safety.
However, it may be a general advice for patients with DVT to prevent further complications or discomfort. Wearing shoes that fit well and avoiding tight clothing can help improve blood circulation in the legs and prevent swelling or pain. Patients with DVT should also elevate their legs when possible and wear compression stockings if prescribed by their doctor.
A patient has been prescribed rivaroxaban (Xarelto) for deep vein thrombosis (DVT). Which statement by the patient indicates understanding of medication teaching?
A. “I will take aspirin if I get a headache.”
Choice A is wrong because aspirin is also an antiplatelet drug that can further increase the risk of bleeding when taken with rivaroxaban. The patient should not take aspirin or any other nonsteroidal anti-inflammatory drugs (NSAIDs) without consulting the prescriber.
B. “I will avoid activities that may cause injury.”
This statement indicates that the patient understands that rivaroxaban (Xarelto) is an anticoagulant that can increase the risk of bleeding and bruising. The patient should avoid activities that may cause injury, such as contact sports, sharp objects, or falls.
C. “I will take my medication with food.”
Choice C is wrong because rivaroxaban can be taken with or without food. The patient does not need to take the medication with food to prevent stomach upset or absorption problems.
D. “I will stop taking my medication if I feel better.”.
Choice D is wrong because rivaroxaban should be taken as prescribed and not stopped abruptly without consulting the prescriber. Stopping the medication can increase the risk of blood clots and stroke. The patient should not stop taking the medication even if they feel better or have no symptoms.

A patient has been prescribed dabigatran (Pradaxa) for atrial fibrillation (AF). Which laboratory test should be monitored while on this medication?
A. Prothrombin time (PT)
Prothrombin time (PT) is wrong because PT measures the extrinsic and common pathways of coagulation, which are not affected by dabigatran. PT is used to monitor warfarin therapy, not dabigatran.
B. International normalized ratio (INR)
International normalized ratio (INR) is wrong because INR is a standardized version of PT that is used to monitor warfarin therapy, not dabigatran. INR is not affected by dabigatran.
C. Activated partial thromboplastin time (aPTT)
Activated partial thromboplastin time (aPTT). Dabigatran (Pradaxa) is a direct oral anticoagulant (DOAC) that inhibits thrombin, a key enzyme in the coagulation cascade. Dabigatran prolongs the aPTT, which is a measure of the intrinsic and common pathways of coagulation.The aPTT can be used to monitor the anticoagulant effect of dabigatran, although routine monitoring is not required.
D. Platelet count.
Platelet count is wrong because platelet count is a measure of the number of platelets in the blood, which are involved in primary hemostasis. Platelet count is not affected by dabigatran, which acts on secondary hemostasis.
E. Platelet count.
