A nurse should include which rationale when instructing a client to avoid sitting with knees crossed?
Decreases risk of skin breakdown behind the knee.
Eliminates pain of arthritis of the lower legs.
Prevents pressure on the popliteal artery.
Avoids irritation of the knee joints.
The Correct Answer is C
The popliteal artery is a major blood vessel that runs behind the knee and supplies blood to the lower leg. Sitting with knees crossed can compress this artery and reduce blood flow to the leg.
This can cause numbness, tingling, or pain in the leg. It can also increase the risk of blood clots or varicose veins.
Choice A is wrong because sitting with knees crossed does not decrease the risk of skin breakdown behind the knee. In fact, it may increase the risk by causing friction or pressure on the skin.
Choice B is wrong because sitting with knees crossed does not eliminate the pain of arthritis in the lower legs.
Arthritis is a joint inflammation that causes pain, stiffness, and swelling. Sitting with knees crossed can worsen these symptoms by putting more stress on the knee joints.
Choice D is wrong because sitting with knees crossed does not avoid irritation of the knee joints.
On the contrary, it can cause irritation by overstretching the knee ligaments and muscles

Correct Answer is C
Explanation
This action would cause the nurse to intervene because it increases the risk of choking and aspiration for a client with dysphagia, which is difficulty swallowing. The nurse would instruct the UAP to feed the client small amounts of food slowly, allowing time for chewing and swallowing.
Choice A is wrong because offering thickened liquids is a safe practice for a client with dysphagia. Thickened liquids allow for easier swallowing and less choking, thus decreasing the chance of aspiration.
Choice B is wrong because placing the client in an upright position is also a safe practice for a client with dysphagia. This position helps prevent food from entering the airway and facilitates swallowing.
Choice D is wrong because allowing ample time between bites is another safe practice for a client with dysphagia. This helps the client avoid feeling rushed or overwhelmed and reduces the risk of aspiration.
Correct Answer is C
Explanation
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.
