Correct Answer: B

Rationale: The correct answer is B: 'Spinach and beef.' Spinach and beef are high in iron, which is crucial for treating iron deficiency anemia. Spinach is a good source of non-heme iron, while beef provides heme iron, making them effective choices to increase iron levels in the body. Yogurt and mozzarella (Choice A), fish and cottage cheese (Choice C), and turkey slices and milk (Choice D) do not contain as high iron content as spinach and beef, making them less effective in addressing iron deficiency anemia.

Correct Answer: C

Rationale: Choice C is the best direction provided by the nurse. This method involves reaching over to the left side rail with the right hand, pulling the body onto its side, bending the upper leg so the foot is on the bed, and pushing down to elevate the trunk. This approach helps maintain spinal alignment while moving from a lying to a standing position, reducing strain on the back. Choices A, B, and D involve movements that are not suitable for a client recovering from a lumbar laminectomy with spinal fusion and could potentially cause harm or discomfort.

Correct Answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.

Correct Answer: A

Rationale: The correct answer is A. Lying flat in the supine position for 12 hours after a renal biopsy is essential to prevent bleeding and promote recovery. This position helps apply pressure to the biopsy site, reducing the risk of bleeding. Choices B, C, and D are incorrect because continuing oral fluids restriction, changing the dressing, and activating the patient-controlled analgesia pump do not directly indicate compliance with the crucial post-biopsy teaching of maintaining the supine position.

Correct Answer: C

Rationale: The Ambulance Squad is the module composed of four medical specialists and two vehicles. This squad is responsible for providing medical care during transportation. Choices A, B, and D are incorrect as they do not match the description provided in the question. The Patient Holding Squad focuses on a different aspect of patient care, the Surgical Squad is more specialized in surgical procedures, and the Area Support Squad provides a different type of support.
