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 B
Explanation
Choice A reason: Marking an outline of the "olive-shaped" mass in the right epigastric area is not a priority nursing action. The mass is caused by hypertrophy of the pyloric sphincter, which obstructs gastric emptying and causes projectile vomiting. The mass may not be palpable in all cases.
Choice B reason: This is the correct answer because maintaining a continuous infusion of IV fluids per prescription is essential to prevent dehydration and electrolyte imbalance in the infant. The infant may have significant fluid loss due to vomiting and poor intake.
Choice C reason: Monitoring amount of intake and infant's response to feedings is important, but not the highest priority. The infant may have difficulty feeding due to nausea, vomiting, and abdominal pain.
Choice D reason: Instructing parents regarding care of the incisional area is a post-operative nursing action, not a pre-operative one. The parents will need to learn how to keep the incision clean and dry, monitor for signs of infection, and administer pain medication as prescribed.
Correct Answer is B
Explanation
Choice A reason: Remove the catheter and palpate the client’s bladder for residual distention. This is not the best action, as it may cause discomfort and trauma to the client. The catheter should not be removed until the bladder is fully emptied or up to 1,000 mL of urine is drained, as removing it too soon may cause urinary retention or infection.
Choice B reason: Allow the bladder to empty completely or up to 1,000 mL of urine. This is the best action, as it can prevent bladder spasms, overdistention, or rupture. The nurse should monitor the urine output and color, and document the amount and characteristics of urine drained.
Choice C reason: Clamp the catheter for thirty minutes and then resume draining. This is not the best action, as it may cause pain and discomfort to the client. The catheter should not be clamped unless ordered by the healthcare provider, as clamping it may increase the risk of infection or bladder damage.
Choice D reason: Remove the catheter and replace with an indwelling catheter. This is not the best action, as it may cause unnecessary exposure and trauma to the client. The catheter should not be replaced unless ordered by the healthcare provider, as replacing it may increase the risk of infection or urethral injury.
