Warfarin sodium (Coumadin) is ordered for a client.
The client asks the nurse about dietary restrictions while taking this medication. Which of the following foods should be limited?
Wheat bread and butter.
Mangoes and tomatoes.
Spinach and salads.
Aged cheeses and wine.
The Correct Answer is C
This is because spinach and salads contain a lot of vitamin K, which can make warfarin less effective at preventing blood clots.
Vitamin K helps the blood to clot, so eating foods high in vitamin K can counteract the effect of warfarin.
Choice A is wrong because wheat bread and butter do not contain a lot of vitamin K and do not affect warfarin.
Choice B is wrong because mangoes and tomatoes do not contain a lot of vitamin K and do not affect warfarin.
Choice D is wrong because aged cheeses and wine do not contain a lot of vitamin K and do not affect warfarin.
It is important to keep a stable diet while taking warfarin and avoid sudden changes in the amount of vitamin K intake. Foods that are high in vitamin K include green leafy vegetables, chickpeas, liver, egg yolks, avocado, and olive oil.
These foods should be limited but not eliminated from the diet. Do not drink cranberry or grapefruit juice while taking warfarin as they can increase the risk of bleeding.

Correct Answer is C
Explanation
Irrigating the tube with 30 mL of sterile saline as needed. This prescription should be questioned by the nurse because it may cause trauma to the kidney or dislodge the tube. The nurse should only irrigate the tube if ordered by the health care provider and with a smaller amount of fluid.
Choice A is wrong because monitoring the urine’s color and odor is an appropriate intervention for a client with a nephrostomy tube. The urine may be bloody or cloudy initially, but it should gradually clear.
Choice B is wrong because recording the intake and output every eight hours is also an appropriate intervention for a client with a nephrostomy tube. The nurse should measure and document the amount and characteristics of urine drainage and report any changes or abnormalities.
Choice D is wrong because measuring the vital signs every four hours during the day is a reasonable prescription for a client with a nephrostomy tube. The nurse should monitor the client for signs of infection, bleeding, or obstruction.
Correct Answer is B
Explanation
This outcome indicates that the client has resolved their constipation and has a regular pattern of defecation without difficulty or discomfort.
Choice A is wrong because taking a laxative daily can worsen constipation by causing dependency and reducing the natural peristalsis of the colon.
Choice C is wrong because requesting a bedpan every four hours does not necessarily mean that the client has bowel movements. It may indicate that the client has difficulty passing stool or has a sensation of incomplete emptying.
Choice D is wrong because having a bowel movement within 72 hours is still considered constipation. Constipation is diagnosed when bowel movements are associated with at least two of the following symptoms, occurring in the past three months with an onset of symptoms of at least six months: Less than three spontaneous bowel movements per week, Lumpy or hard stools from at least 25% of bowel movements.
