A client is being discharged with a prescription for warfarin. Which instruction should the nurse provide this client regarding diet?
Increase the intake of dark green leafy vegetables while taking warfarin.
Eat two servings of dark green leafy vegetables daily and continue for 30 days after warfarin therapy is completed.
Eat approximately the same amount of leafy green vegetables daily so the amount of vitamin K consumed is consistent.
Avoid eating any foods that contain any vitamin K because it is an antagonist of warfarin.
The Correct Answer is C
Choice A reason: Increasing the intake of dark green leafy vegetables while taking warfarin is not a good instruction because it can decrease the effectiveness of warfarin. Dark green leafy vegetables are rich in vitamin K, which is a coagulation factor that counteracts the anticoagulant effect of warfarin.
Choice B reason: Eating two servings of dark green leafy vegetables daily and continuing for 30 days after warfarin therapy is completed is not a good instruction because it can cause bleeding complications. Dark green leafy vegetables are rich in vitamin K, which is a coagulation factor that counteracts the anticoagulant effect of warfarin. Stopping warfarin while continuing to eat high amounts of vitamin K can increase the risk of clot formation and thromboembolism.
Choice C reason: This is the correct answer because eating approximately the same amount of leafy green vegetables daily so the amount of vitamin K consumed is consistent is a good instruction because it can help maintain a stable therapeutic level of warfarin. Dark green leafy vegetables are rich in vitamin K, which is a coagulation factor that counteracts the anticoagulant effect of warfarin. Keeping a consistent intake of vitamin K can help avoid fluctuations in warfarin's effect and prevent bleeding or clotting episodes.
Choice D reason: Avoiding eating any foods that contain any vitamin K because it is an antagonist of warfarin is not a good instruction because it can cause bleeding complications. Dark green leafy vegetables are rich in vitamin K, which is a coagulation factor that counteracts the anticoagulant effect of warfarin. Eliminating vitamin K from the diet can increase the sensitivity to warfarin and cause excessive bleeding and bruising.

Correct Answer is C
Explanation
Choice A reason: Conversion of the client's PPD test from negative to positive is not the most important information for the nurse to note, as this is an expected finding for a client who has been exposed to tuberculosis and does not affect the administration of isoniazid. This is a distractor choice.
Choice B reason: History of intravenous drug abuse is not the most important information for the nurse to note, as this is not directly related to the use of isoniazid and does not contraindicate its administration. This is another distractor choice.
Choice C reason: Current diagnosis of hepatitis B is the most important information for the nurse to note, as this can increase the risk of hepatotoxicity and liver damage from isoniazid, which requires close monitoring and possible dose adjustment. Therefore, this is the correct choice.
Choice D reason: Length of time of the exposure to tuberculosis is not the most important information for the nurse to note, as this does not influence the dosage or frequency of isoniazid and does not indicate any complication or adverse reaction. This is another distractor choice.
Correct Answer is D
Explanation
Choice A reason: Creatinine is not a relevant laboratory test for the nurse to monitor, as this reflects renal function and is not affected by naproxen or arthritis. This is a distractor choice.
Choice B reason: Serum calcium is not a pertinent laboratory test for the nurse to monitor, as this indicates bone metabolism and is not related to naproxen or arthritis. This is another distractor choice.
Choice C reason: Erythrocyte sedimentation rate is not an important laboratory test for the nurse to monitor, as this measures inflammation and is not influenced by naproxen or stomach pain. This is another distractor choice.
Choice D reason: Hemoglobin is an essential laboratory test for the nurse to monitor, as this shows blood oxygen-carrying capacity and can be reduced by naproxen-induced gastrointestinal bleeding, which can cause stomach pain, weakness, and fatigue. Therefore, this is the correct choice.
