ATI RN Custom Exams Set 1

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: B

Rationale: The correct answer is B: Iodine. Iodine is essential for thyroid hormone production, and its deficiency can contribute to hypothyroidism. While calcium, vitamin C, and iron are important for overall health, they are not specifically related to thyroid function. Calcium is more associated with bone health, vitamin C with immune function, and iron with red blood cell production.

Correct Answer: A

Rationale: The correct answer is A. Lying flat in the supine position for 12 hours after a renal biopsy helps prevent bleeding, which is crucial for the client's recovery. This position aids in applying pressure to the biopsy site, reducing the risk of bleeding and ensuring optimal healing. Choices B, C, and D do not directly relate to compliance with client teaching after a renal biopsy. Continuing oral fluids restriction, changing the dressing, or activating a patient-controlled analgesia pump are not specific instructions aimed at promoting recovery and preventing complications post renal biopsy.

Correct Answer: C

Rationale: The correct answer is to wear extra warm clothing during cold exposure. This instruction is crucial for managing Raynaud's phenomenon as it helps prevent vasospasms triggered by cold temperatures. Choice A is incorrect because exacerbations can occur in any season. Choice B is not directly related to managing Raynaud's phenomenon. Choice D is also irrelevant as direct sunlight exposure does not typically worsen symptoms of Raynaud's phenomenon.

Correct Answer: C

Rationale: When a patient is prescribed an oral anticoagulant, the nurse should monitor for signs of bleeding. Oral anticoagulants work by inhibiting the blood's ability to clot, which increases the risk of bleeding. Monitoring for signs of bleeding such as easy bruising, petechiae, hematuria, or bleeding gums is crucial to prevent complications. Elevated blood glucose (Choice A) is not directly related to oral anticoagulant use. Decreased blood pressure (Choice B) is not a common effect of oral anticoagulants. Increased appetite (Choice D) is not a typical side effect of oral anticoagulants and is not a primary concern when monitoring a patient on this medication.
