Correct Answer: A

Rationale: The correct answer is A: 'Monitor INR levels and check for bleeding.' When a patient is receiving anticoagulant therapy, nurses must monitor the patient's INR levels to ensure that the anticoagulants are within the therapeutic range and also watch for signs of bleeding, which is a common side effect of anticoagulants. Option B is incorrect because while patient education is important, dietary restrictions are not a direct nursing consideration when administering anticoagulant therapy. Option C is not a specific nursing consideration related to anticoagulant therapy. Option D is incorrect as keeping the patient immobile is not a standard nursing practice for patients on anticoagulant therapy, as mobility is often encouraged to prevent complications like deep vein thrombosis.

Correct Answer: B

Rationale: When caring for clients with dementia, addressing restlessness and agitation is a priority as it can lead to distress, safety risks, and potential harm to the client or others. Restlessness and agitation are common behavioral symptoms of dementia and can indicate unmet needs, discomfort, or confusion. Managing these symptoms promptly can help improve the client's quality of life and prevent complications such as falls, injuries, or escalation of challenging behaviors. While other issues like mild confusion, incontinence, and wandering are also important to address, managing restlessness and agitation takes precedence due to its immediate impact on the client's well-being and safety.

Correct Answer: C

Rationale: The correct answer is C: Apply a sequential compression device. Applying a sequential compression device promotes venous return by assisting with blood circulation in the lower extremities, reducing the risk of blood clots. Encouraging deep breathing exercises can help with lung expansion but does not directly promote venous return. Maintaining the client in a supine position may not be ideal for promoting venous return if the client is unable to move. Massaging the client's legs may be contraindicated postoperatively due to the risk of dislodging a clot or causing trauma to the surgical site.

Correct Answer: A

Rationale: The correct answer is to ensure the blood is compatible with the recipient's blood type. This is crucial to prevent transfusion reactions, which can be life-threatening. Choice B is incorrect because warming blood to body temperature is not a standard practice and may lead to hemolysis. Choice C is incorrect as blood products are carefully screened for clots before distribution. Choice D is incorrect because it is not necessary for the recipient to eat before a blood transfusion.

Correct Answer: B

Rationale: The correct answer is B: Ensure the blood type is compatible with the client. This is the most crucial step in preparing for a blood transfusion to prevent severe transfusion reactions. Checking the client for a fever (Choice A) is important but not the most critical step. Administering blood via IV push (Choice C) is incorrect as blood transfusions are usually administered as a slow drip. Warming the blood to body temperature (Choice D) is not a standard practice and can lead to hemolysis, making it an incorrect choice.
