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 A
Explanation
Choice A: 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: 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: 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: 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 B
Explanation
Choice A: Assigning the UAP to provide care for another client and assume full care of the client is not an action that the nurse should take, as this is unnecessary and inefficient. The UAP can safely assist the client with influenza if they follow proper infection control measures. This is an incorrect choice.
Choice B: Reviewing the need for the UAP to wear a face mask while in close contact with the client is an action that the nurse should take, as this can protect the UAP and others from droplet transmission of influenza. This is a standard precaution that should be reinforced by the nurse. Therefore, this is the correct choice.
Choice C: Instructing the UAP to apply a fitted respirator mask before entering the client's room is not an action that the nurse should take, as this is not indicated for a client with influenza. A respirator mask is required for airborne transmission, not droplet transmission. This is another incorrect choice.
Choice D: Directing the UAP to notify the nurse of any changes in the client's respiratory status is not an action that the nurse should take, as this is a general instruction that does not address the specific issue of infection control. This is another incorrect choice.
