Question 1 of 5
A nurse is collecting data from a client who has a prosthetic aortic valve and takes warfarin daily at bedtime. Which of the following data is the priority finding for the nurse to report to the provider?
Correct Answer: B
Rationale: The correct answer is B: The client keeps a small supply of vitamin K tablets on hand for emergency use. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Introducing additional vitamin K can counteract the effects of warfarin, leading to an increased risk of clotting.
Therefore, it is crucial for the nurse to report this finding to the provider to ensure the client's safety.
A: The client sprinkles flaxseeds on breakfast food every day. Flaxseeds are not contraindicated with warfarin therapy, so this finding is not a priority to report.
C: The client uses garlic as a daily dietary supplement. While garlic can interact with warfarin, it is less likely to cause significant effects compared to vitamin K supplementation.
D: The client consistently eats fish for dinner twice weekly. Fish consumption may affect warfarin levels but is not as critical as having vitamin K tablets on hand for
Question 2 of 5
When beginning herbal products, the nurse understands that the best way to identify allergic or other adverse reactions is to:
Correct Answer: B
Rationale: The correct answer is B because starting with a lower dose allows for monitoring adverse reactions. By gradually increasing the dose, any potential allergic reactions or adverse effects can be identified early. Checking with a pharmacist (
A) is helpful but may not provide real-time monitoring like starting with a lower dose. Using only one herbal preparation at a time (
C) is a good practice, but it does not specifically address identifying allergic reactions. Never taking with prescription medications (
D) is incorrect as some herbal products may interact with prescriptions but does not directly relate to identifying allergic reactions.
Question 3 of 5
The patient is to be started on warfarin (Coumadin) therapy. It is important for the nurse to check for the use of which herbs? (Select All that Apply.)
Correct Answer: A,B,C,D,E
Rationale: The correct answer is A, B, C, D, and E. When starting a patient on warfarin therapy, it is crucial to check for the use of herbs that can interact with the medication. Echinacea can increase the risk of bleeding when combined with warfarin. Garlic may also potentiate the anticoagulant effects of warfarin. Ginseng can interfere with warfarin's effectiveness. Valerian has potential interactions with warfarin, affecting blood clotting. Ginger can also increase the risk of bleeding when used with warfarin. Checking for the use of these herbs is essential to prevent dangerous interactions and ensure the effectiveness of warfarin therapy.
Question 4 of 5
Which of the following is administered to increase the number of circulating red blood cells?
Correct Answer: B
Rationale: The correct answer is B: Epoetin alfa (Procrit). Epoetin alfa is a synthetic form of erythropoietin, a hormone that stimulates the production of red blood cells in the bone marrow. By administering epoetin alfa, the number of circulating red blood cells can be increased, making it an effective treatment for anemia.
A: Oprelvekin (Neumega) is a thrombopoietin agonist used to stimulate platelet production, not red blood cells.
C: Clopidogrel (Plavix) is an antiplatelet medication used to prevent blood clots, unrelated to red blood cell production.
D: Filgrastim (Neupogen) is a granulocyte colony-stimulating factor used to increase white blood cell production, not red blood cells.
Question 5 of 5
Why is it important for the nurse to collect information from the patient about the use of complementary and alternative medicine (CAM)?
Correct Answer: D
Rationale: The correct answer is D. It is important for the nurse to collect information about the patient's use of CAM because CAM therapies could interact with prescription and OTC medications. This is crucial in ensuring patient safety and avoiding potential harmful interactions. By knowing the full picture of the patient's health practices, the nurse can provide comprehensive and personalized care.
Choice A is incorrect as some CAM therapies have shown effectiveness.
Choice B is incorrect as additional treatment might indeed be necessary.
Choice C is incorrect as not all CAM therapies are dangerous.
