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: Obtain a capillary glucose level. This is the first action that the nurse should do, as it can diagnose hypoglycemia, which is a low blood sugar level that can cause jitteriness and tachypnea in newborns. Hypoglycemia can be caused by maternal diabetes, prematurity, infection, or delayed feeding. The nurse should check the glucose level using a heel stick and a glucometer.
Choice B reason: Feed 30 mL of 10% dextrose in water. This is not the first action that the nurse should do, as it may not be appropriate for all newborns with jitteriness and tachypnea. Feeding 10% dextrose in water can raise the blood sugar level, but it may also cause rebound hypoglycemia or fluid overload. The nurse should feed only after confirming hypoglycemia and obtaining a healthcare provider's order.
Choice C reason: Wrap tightly in a blanket. This is not the first action that the nurse should do, as it may not address the underlying cause of jitteriness and tachypnea in newborns. Wrapping tightly in a blanket can prevent heat loss and conserve energy, but it may also impair breathing or circulation. The nurse should wrap only after ruling out other causes of jitteriness and tachypnea.
Choice D reason: Encourage the mother to breastfeed. This is not the first action that the nurse should do, as it may not be feasible or effective for all newborns with jitteriness and tachypnea. Breastfeeding can provide nutrition and bonding for newborns, but it may also be difficult or contraindicated for some newborns with respiratory distress or infection. The nurse should encourage breastfeeding only after assessing and stabilizing the newborn's condition.
Correct Answer is B
Explanation
Choice B reason: initiating a continuous infusion of IV fluids per prescription has highest priority for an infant with pyloric stenosis who is scheduled for a pyloromyotomy. Pyloric stenosis causes projectile vomiting and dehydration, which can lead to metabolic alkalosis and electrolyte imbalance. The infant needs IV fluids to correct these abnormalities and prevent complications.
Choice A reason: marking an outline of the “olive-shaped” mass in the right epigastric area is not a priority action for an infant with pyloric stenosis who is scheduled for a pyloromyotomy. The “olive-shaped” mass is a palpable sign of pyloric stenosis, but it does not require any intervention before surgery.
Choice C reason: monitoring amount of intake and infant's response to feedings is not a priority action for an infant with pyloric stenosis who is scheduled for a pyloromyotomy. The infant may have difficulty feeding due to vomiting and gastric distension, which can worsen their dehydration and malnutrition. The infant may need to be kept NPO (nothing by mouth) before surgery.
Choice D reason: instructing parents regarding care of the incisional area is not a priority action for an infant with pyloric stenosis who is scheduled for a pyloromyotomy. The incisional area will need proper care after surgery, but this can be taught later when the infant is stable and ready for discharge.
