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 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 ["4"]
Explanation
Step 1 is to convert the child’s weight from pounds to kilograms.
44 pounds ÷ 2.2 = 20 kilograms.
Result at each step = 20 kilograms.
Step 2 is to calculate the total dosage of furosemide in milligrams.
2 mg × 20 kg = 40 mg.
Result at each step = 40 mg.
Step 3 is to determine the volume of medication to administer in milliliters.
40 mg ÷ 10 mg/mL = 4 mL.
Result at each step = 4 mL.
The nurse should administer 4 mL.
Correct Answer is ["B","C","E","F"]
Explanation
Choice B is correct because weight management is an important factor in preventing and controlling hypertension. Taking daily walks for thirty minutes can help reduce weight and lower blood pressure.
Choice C is correct because salt substitutes can help with maintaining a healthy diet by reducing sodium intake. Sodium intake is associated with increased blood pressure and should be limited to less than 2,300 mg per day.
Choice E is correct because sodium intake can be regulated by rinsing canned foods in water. Canned foods often contain high amounts of sodium as a preservative and rinsing them can remove some of the excess sodium.
Choice F is correct because uncontrolled hypertension can lead to renal damage. Hypertension can cause damage to the blood vessels and impair the function of the kidneys, leading to chronic kidney disease or failure.
Choice A is incorrect because alcohol consumption can produce vascular changes that increase blood pressure. Alcohol intake should be limited to no more than one drink per day for women and two drinks per day for men.
Choice D is incorrect because blood pressure readings should not be taken at noontime. Blood pressure readings should be taken at the same time each day, preferably in the morning before breakfast or in the evening before dinner.
