Correct Answer: A

Rationale: Step 1: Reassessing the wound and client's condition allows the nurse to identify any factors contributing to the lack of improvement. Step 2: It helps determine if the current care plan needs modifications or if there are underlying issues affecting healing. Step 3: This step ensures a comprehensive evaluation before making any changes to the care plan, promoting evidence-based practice. Step 4: Choosing this option aligns with the nursing process of assessment, which is crucial for making informed decisions in client care. Summary: Option A is correct as it emphasizes the importance of reassessment to gather more information and make informed decisions. Discontinuing the care plan (Option B) without assessment can be harmful. Increasing dressing changes (Option C) may not address the underlying issue. Referring immediately (Option D) may be premature without reassessment.

Correct Answer: B

Rationale: The correct answer is B: Health behavior. Evaluating the patient's demonstration of self-injection assesses their ability to perform a specific health-related action. This choice focuses on the patient's actions and behaviors related to their health, aligning with the scenario provided. Choice A: Health status is incorrect because it refers to the patient's current physical condition, not their ability to perform a specific health action. Choice C: Psychological self-control is incorrect as it pertains to the patient's ability to regulate their emotions and impulses, not their ability to self-administer injections. Choice D: Health service utilization is incorrect as it relates to the frequency and pattern of healthcare services used by the patient, not their ability to perform a specific health behavior.

Correct Answer: D

Rationale: The correct answer is D: 200 CD4+ cells. In AIDS, the immune system is severely compromised, leading to a decrease in CD4+ T cells. A CD4+ count below 200 cells/mm3 is a key indicator of AIDS, as it signifies advanced immunodeficiency. Choices A, B, and C all have CD4+ cell counts above 200, which would not support the occurrence of AIDS. Therefore, the nurse would evaluate a CD4+ count of 200 cells as laboratory data that support the occurrence of AIDS.

Correct Answer: C

Rationale: Step 1: Reading labels carefully on vials containing flush solutions for locks is crucial to ensure the correct solution is being used. Step 2: Potassium chloride should not be used to flush locks as it can be fatal if administered incorrectly. Step 3: By carefully reading labels, the nurse can verify that the correct solution is being used, thus minimizing the risk of using potassium chloride. Summary: - Choice A is incorrect as using a dilute form of potassium chloride does not address the issue of incorrect administration. - Choice B is incorrect as warming the solution does not prevent the risk associated with using potassium chloride. - Choice D is incorrect as replacing locks does not address the root cause of the issue, which is improper administration.

Correct Answer: A

Rationale: The correct answer is A: Include potassium-rich foods. Diuretics can cause potassium loss, leading to hypokalemia. Including potassium-rich foods helps prevent this deficiency. Choice B is incorrect because fruits and fruit juices are often good sources of potassium. Choice C is incorrect as protein-rich foods do not specifically address potassium needs. Choice D is incorrect as dairy products are also good sources of potassium. Therefore, recommending potassium-rich foods is essential to prevent hypokalemia in clients taking diuretics.
