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: Moderate amount of foul-smelling lochia. This is the most indicative finding of a postpartum infection, as it suggests that the client has endometritis, which is an inflammation of the uterine lining. Endometritis is a common cause of maternal morbidity and mortality, and requires prompt antibiotic treatment.
Choice B reason: Blood pressure of 122/74 mm Hg. This is a normal blood pressure for a postpartum client, and does not indicate an infection. The reference range for blood pressure is 90/60 to 140/90 mm Hg.
Choice C reason: Oral temperature of 100.2°F (37.9°C). This is a slightly elevated temperature for a postpartum client, but it does not necessarily indicate an infection. The reference range for oral temperature is 97.6 to 99.6°F (36.4 to 37.6°C). A mild fever may occur in the first 24 hours after delivery due to dehydration or hormonal changes.
Choice D reason: White blood cell count of 19,000/mm³ (19 x 10⁹/L). This is a high white blood cell count for a postpartum client, but it does not indicate an infection. The reference range for white blood cell count is 5,000 to 10,000/mm³ (5 to 10 x 10⁹/L). A leukocytosis may occur in the first few days after delivery due to stress or tissue injury.
Correct Answer is ["A","B","E"]
Explanation
Choice A reason: This is a correct answer because obtaining postoperative vital signs for a client one day following unilateral knee arthroplasty is a nursing action that can be assigned to the PN. Vital signs are measurements of the body's basic functions, such as temperature, pulse, blood pressure, and respiration. Vital signs should be monitored regularly after surgery to detect any signs of infection, bleeding, shock, or pain. The PN has the knowledge and skill to measure and record vital signs and report any abnormal findings to the nurse.
Choice B reason: This is a correct answer because performing daily surgical dressing change for a client who had an abdominal hysterectomy is a nursing action that can be assigned to the PN. Surgical dressing is a material that covers and protects a wound from infection, bleeding, or contamination. Surgical dressing should be changed daily or as needed to keep the wound clean and dry and promote healing. The PN has the knowledge and skill to perform surgical dressing change using sterile technique and appropriate equipment and report any signs of wound infection or dehiscence to the nurse.
Choice C reason: Initiating patient controlled analgesia (PCA) pumps for two clients immediately postoperatively is not a nursing action that can be assigned to the PN. PCA pump is a device that allows the client to self-administer pain medication through an IV line by pressing a button. PCA pump should be initiated by the nurse after verifying the prescription, setting the parameters, educating the client, and ensuring safety and effectiveness. The PN does not have the authority or competency to initiate PCA pump or adjust its settings.
Choice D reason: Starting the second blood transfusion for a client twelve hours following a below knee amputation is not a nursing action that can be assigned to the PN. Blood transfusion is a procedure that delivers donated blood or blood products into the client's bloodstream through an IV line. Blood transfusion should be started by the nurse after verifying the prescription, checking the blood type and compatibility, obtaining informed consent, and monitoring for any adverse reactions. The PN does not have the authority or competency to start blood transfusion or manage its complications.
Choice E reason: This is a correct answer because monitoring a dose of warfarin per protocol for a client with type 2 diabetes mellitus (DM) is a nursing action that can be assigned to the PN. Warfarin is an anticoagulant medication that prevents blood clots by inhibiting vitamin K dependent clotting factors. Warfarin should be monitored per protocol by checking the international normalized ratio (INR), which measures how long it takes for blood to clot. The PN has the knowledge and skill to monitor warfarin per protocol by obtaining blood samples, performing point-of-care testing, and reporting results to the nurse.
