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 ["D"]
Explanation
Older adults do not have a different pain mechanism and do not feel it as much as younger individuals. This statement is false and indicates the need for further education regarding pain management in older adults.
Some possible explanations for the other choices are:
Choice A is true because older adults often fear becoming addicted to pain medications and may underreport or deny their pain.
Choice B is true because older adults often take numerous drugs that can cause interactions with pain medications and increase the risk of adverse effects.
Choice C is true because confusion and delirium can be a more common reaction to certain pain medications in the elderly, especially opioids and benzodiazepines.
Normal ranges for vital signs in older adults are similar to those in younger adults, except for blood pressure, which may be higher due to arterial stiffness. The normal range for blood pressure in older adults is 120/80 to 140/90 mm Hg.
Correct Answer is B
Explanation
To find the rate of the pump in ml/hour, you need to first convert the client’s weight from pounds to kilograms. You can do this by dividing the weight by 2.2046 or multiplying it by 0.454.
For example:
297 lbs / 2.2046 = 134.72 kg or 297 lbs x 0.454 = 134.72 kg
Then, you need to multiply the client’s weight in kilograms by the ordered dose in units/kg/hour to get the total units per hour.
For example:
134.72 kg x 12 units/kg/hour = 1616.64 units/hour
Next, you need to set up a proportion to find the rate of the pump in ml/hour using the supplied medication concentration.
For example:
25,000 units / 500 ml = 1616.64 units / X ml Cross-multiply and solve for X:
25,000 x X = 808320 X = 808320 / 25000 X = 32.33 ml/hour
Finally, you need to round your answer to the nearest tenth of a ml/hour as per the medication administration guidelines.
For example:
32.33 ml/hour ≈ 32.3 ml/hour
Therefore, the rate of the pump is 32.3 ml/hour.
Choice A is wrong because it uses a different conversion factor for pounds to kilograms (1 lb = 0.5 kg) which is not accurate.
Choice C is wrong because it uses a different ordered dose (10 units/kg/hour) which is not what the provider has written.
Choice D is wrong because it uses a different supplied medication concentration (20,000 units in 500 ml) which is not what is available.
