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:

Avoid foods that are high in vitamin K.

Administer injections into areas with decreased subcutaneous tissue.

Massage injection sites after administration.

Use a soft-bristled toothbrush.

Answer and Explanation

The Correct Answer is D

The correct answer is choice 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.

Choice A) 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.

Choice B) 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.

Choice C) 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.

Correct Answer is ["C","E"]

Explanation

Verapamil is a calcium channel blocker that is used to treat variant angina by dilating the coronary arteries and relieving the chest pain caused by spasms.It also reduces blood pressure and heart rate, but these are not the expected outcomes for variant angina.

Choice A is wrong because verapamil decreases heart rate, not increases it.This can help reduce the oxygen demand of the heart, but it is not the main goal of therapy for variant angina.

Choice B is wrong because verapamil decreases contractility, not increases it.This can also help reduce the oxygen demand of the heart, but it is not the main goal of therapy for variant angina.

Choice D is wrong because verapamil reduces blood pressure, not increases it.This can help lower the workload of the heart, but it is not the main goal of therapy for variant angina.

Normal ranges for heart rate are 60 to 100 beats per minute, for blood pressure are 120/80 mm Hg or lower, and for contractility are measured by ejection fraction, which is normally 55% or higher.

A. Ibuprofen B. Naproxen C. Acetaminophen D. Aspirin.

Correct Answer is C

Explanation

The patient reports having frequent headaches and asks for an over-the-counter pain reliever.The nurse will recommend acetaminophen, which is the safest pain reliever while taking warfarin.Acetaminophen does not interfere with the anticoagulant effect of warfarin and does not increase the risk of bleeding.

Choice A is wrong because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can enhance the anticoagulant effect of warfarin and increase the likelihood of harmful bleeding.

NSAIDs can also cause stomach ulcers, kidney damage, and high blood pressure.

Choice B is wrong because naproxen is another NSAID that has the same risks as ibuprofen.

Naproxen should be avoided by patients taking warfarin.

Choice D is wrong because aspirin is also an anticoagulant that can increase the risk of bleeding when taken with warfarin.

Aspirin can also cause stomach irritation, ulcers, and allergic reactions.

The normal range for INR is 2 to 3 for patients with atrial fibrillation who are taking warfarin.

An INR of 2.5 indicates that the patient’s blood is taking longer to clot than normal, but not too long.

The patient should have regular blood tests to monitor their INR and adjust their warfarin dose if needed.
