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 A
Explanation
Choice A reason: Observing insertion site is an essential assessment for a client who has a suprapubic catheter. The insertion site is located in the lower abdomen, where urine drains from an opening in the bladder through a catheter into a drainage bag. The nurse should inspect the site for signs of infection, inflammation, bleeding, or leakage. The nurse should also clean the site with soap and water and apply a sterile dressing as needed.
Choice B reason: Palpating flank area is not a relevant assessment for a client who has a suprapubic catheter. The flank area is located on the sides of the back, where the kidneys are located. Palpating the flank area can detect tenderness or pain that may indicate kidney infection or stones, but it does not provide information about the suprapubic catheter or its function.
Choice C reason: Measuring abdominal girth is not a relevant assessment for a client who has a suprapubic catheter. The abdominal girth is the circumference of the abdomen at the level of the umbilicus. Measuring abdominal girth can detect changes in fluid balance, ascites, or bowel obstruction, but it does not provide information about the suprapubic catheter or its function.
Choice D reason: Assessing perineal area is not a relevant assessment for a client who has a suprapubic catheter. The perineal area is located between the anus and the genitals. Assessing perineal area can detect signs of infection, irritation, or injury in the genital or anal regions, but it does not provide information about the suprapubic catheter or its function.
Correct Answer is ["A","C","D"]
Explanation
Choice A reason: Taking metformin with the morning and evening meal is a correct statement for the nurse to include, as this can improve the absorption and effectiveness of metformin and reduce the risk of gastrointestinal side effects. Therefore, this is a correct choice.
Choice B reason: Using sliding scale insulin for frequent blood glucose elevations is not a correct statement for the nurse to include, as this is not recommended for clients with type 2 DM who are taking metformin. This can cause hypoglycemia and complicate the management of blood glucose levels. This is an incorrect choice.
Choice C reason: Recognizing signs and symptoms of hypoglycemia is a correct statement for the nurse to include, as this can help the client identify and treat low blood glucose levels, which can occur with metformin use or other factors such as exercise, fasting, or alcohol intake. Therefore, this is another correct choice.
Choice D reason: Reporting persistent polyuria to the health care provider is a correct statement for the nurse to include, as this can indicate poor glycemic control or a complication of DM such as diabetic ketoacidosis or nephropathy. Therefore, this is another correct choice.
Choice E reason: Taking an additional dose for signs of hyperglycemia is not a correct statement for the nurse to include, as this can cause overdose or toxicity of metformin, which can lead to lactic acidosis and renal failure. This is another incorrect choice.
