Correct Answer: B

Rationale: The correct answer is B because maintaining the head of the bed at a 30-degree angle can cause the radioactive material to shift within the client's body, increasing the risk of radiation exposure. This position should be avoided to prevent displacement of the applicator. A: Strict bed rest is appropriate to minimize movement and dislodgement of the applicator, ensuring proper treatment delivery. C: Providing a bed bath does not pose a radiation hazard as long as proper precautions are taken. D: Checking the applicator's position every 4 hours is essential for monitoring and ensuring it remains in place to deliver the intended treatment.

Correct Answer: C

Rationale: The correct answer is C: An inference. When the nurse documents that the client is confused, it is an interpretation or conclusion drawn from the observed behavior or symptoms. Inferences are based on subjective and objective data. Subjective data (choice A) is based on what the client states, while a data cue (choice B) is a piece of information that may lead to an inference but is not the actual interpretation. Primary data (choice D) refers to firsthand information obtained directly from the client, which is not the case here. In this scenario, the nurse is making an inference based on the observed confusion, making choice C the correct answer.

Correct Answer: A

Rationale: The correct answer is A: Citrus fruits and green leafy vegetables. Citrus fruits and green leafy vegetables are good sources of Vitamin C and iron, which are essential for individuals with iron deficiency anemia. Vitamin C enhances the absorption of iron from plant-based sources, while green leafy vegetables provide iron. Bananas and nuts (choice B) are not significant sources of iron. Coffee and tea (choice C) can inhibit iron absorption. Dairy products (choice D) are not high in iron and can also inhibit iron absorption. Therefore, choosing citrus fruits and green leafy vegetables indicates understanding of the dietary instructions for managing iron deficiency anemia.

Correct Answer: B

Rationale: The correct answer is B: Make recommendations for revising the plan of care. When client outcomes are not met within the specified time frame, the nurse should reassess the plan of care to identify any potential reasons for the lack of progress. By making recommendations for revising the plan of care, the nurse can adjust interventions to better align with the client's needs and facilitate goal achievement. Continuing to follow the written plan of care (choice A) without modification may not address the underlying issues preventing goal attainment. Asking another health care professional to design a plan of care (choice C) may not be necessary if the nurse can assess and revise the current plan. Stating 'goal will be met at a later date' (choice D) does not address the need for immediate action to reassess and modify the plan for better outcomes.

Correct Answer: C

Rationale: The correct answer is C: Pulmonary artery obstructive pressure (PACP). The multilumen pulmonary artery catheter measures hemodynamic pressures in the heart. When the catheter tip enters small branches of the pulmonary artery, it can assess Central Venous Pressure (A), Pulmonary Artery Capillary Pressure (B), and Pulmonary Artery Wedge Pressure (D). Pulmonary artery obstructive pressure is not a standard hemodynamic measurement and is not assessed using this catheter. It is crucial to differentiate between the various pressures measured to accurately assess the patient's cardiac status.
