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
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 3 of 5
A nurse is reviewing the laboratory report of a client and realizes the liver function tests are elevated, indicating liver damage. The client should be monitored for which potential complication?
Correct Answer: B
Rationale: The correct answer is B: Abnormal coagulation. Elevated liver function tests indicate liver damage, which can impair the liver's ability to produce clotting factors, leading to abnormal coagulation. This can result in increased risk of bleeding or clotting disorders. Monitoring for abnormal coagulation is crucial to prevent complications such as excessive bleeding or blood clots. Reduced cardiac output (
A), electrolyte imbalance (
C), and respiratory issues (
D) are not directly associated with liver damage and elevated liver function tests.
Question 4 of 5
A nurse is reinforcing teaching for a client who has a new prescription for warfarin. Which of the following information should the nurse include?
Correct Answer: B
Rationale: The correct answer is B: The client should use an electric razor while on this medication. This is because warfarin is a blood thinner that can increase the risk of bleeding. Using an electric razor instead of a manual razor can help prevent cuts and reduce the risk of bleeding. Options A, C, and D are incorrect. A client should never double the dose of warfarin if they miss a dose as it can lead to an increased risk of bleeding. Mild nosebleeds are not common during initial treatment with warfarin, and warfarin actually decreases the risk of deep vein thrombosis rather than increasing it.
Question 5 of 5
A nurse is collecting data from a client who is receiving clopidogrel following the placement of a cardiac stent. Which of the following findings should the nurse identify as an adverse effect of this medication?
Correct Answer: C
Rationale: The correct answer is C: Black stools. Clopidogrel is an antiplatelet medication commonly used after cardiac stent placement. Its adverse effect includes gastrointestinal bleeding, which can manifest as black, tarry stools due to upper GI bleeding. Hypothermia (
A) and hypotension (
B) are not typically associated with clopidogrel. Constipation (
D) is not a common adverse effect of this medication.
