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
This is because the recovery position helps maintain the airway and prevent aspiration, and loosening the necktie prevents breathing restriction.
The other choices are wrong because:
Choice A is wrong because placing a stick or any object in the person’s mouth can cause injury to the teeth, gums, tongue or jaw and obstruct the airway. The person cannot swallow or bite their tongue during a seizure.
Choice B is wrong because recording the time of the seizure is not the first priority. The first priority is to ensure the safety and comfort of the person.
Choice C is wrong because restraining the limbs can cause injury or fracture, increase agitation and prolong the seizure. The nurse should protect the person from injury by moving furniture away and padding the head.
Normal ranges for seizure duration are usually less than 5 minutes for generalized tonic-clonic seizures and less than 15 seconds for absence seizures. If the seizure lasts longer than 5 minutes, or if the person has repeated seizures without regaining consciousness, it is considered a medical emergency and requires immediate treatment.
Correct Answer is A
Explanation
Rhonchi. Rhonchi are low-pitched, rattling sounds that indicate mucus in the larger airways. They are most evident on expiration and may decrease after coughing.
Choice B is wrong because wheezes are high-pitched, squeaking sounds that indicate narrowed small air passages. They are usually heard on both inspiration and expiration.
Choice C is wrong because crackles are short, high-pitched popping sounds that indicate fluid or inflammation in the alveoli. They are usually heard on inspiration.
Choice D is wrong because pleural friction rubs are creaking or grating sounds that indicate inflammation of the pleura. They are usually heard on both inspiration and expiration and do not change with coughing.
