Correct Answer: C

Rationale: The correct answer is C because thiotepa is a cell cycle-nonspecific alkylating agent that interferes with both DNA replication and RNA transcription. Thiotepa works by cross-linking DNA strands, leading to inhibition of DNA replication and transcription, ultimately causing cell death. This mechanism of action makes it effective against actively dividing cells, such as cancer cells. Choice A is incorrect because thiotepa does not interfere with DNA replication alone. Choice B is incorrect because thiotepa affects both DNA replication and RNA transcription, not just RNA transcription. Choice D is incorrect because thiotepa does not destroy the cell membrane; instead, it acts on the genetic material within the cell.

Correct Answer: A

Rationale: The correct answer is A because when a client's condition improves, resolved nursing diagnoses should be removed from the care plan to reflect the current status accurately. This ensures the care plan remains relevant and effective. Continuing with the existing plan (choice B) may lead to unnecessary interventions. Focusing only on unresolved issues (choice C) overlooks the importance of updating the care plan comprehensively. Delegating the task to another nurse or staff member (choice D) is not appropriate as the nurse updating the care plan should have a thorough understanding of the client's progress and needs.

Correct Answer: A

Rationale: The correct answer is A because the "Where is the pain located?" question corresponds to the "P" component in the PQRST assessment, which stands for Provocative/Palliative factors. This question helps identify the specific location of the pain and what triggers or alleviates it. The other choices are incorrect because: - B: "What causes the pain?" corresponds to the "Q" component (Quality of pain), focusing on the characteristics of the pain. - C: "Does it come and go?" corresponds to the "R" component (Region/Radiation of pain), focusing on the pattern and radiation of the pain. - D: "What does the pain feel like?" corresponds to the "S" component (Severity of pain), focusing on the intensity of the pain.

Correct Answer: A

Rationale: The correct answer is A: Wait for the patient to complete the sentence. This is the most appropriate intervention for a patient with aphasia because rushing the patient or providing suggestions can be counterproductive. Waiting allows the patient time to find the words they are looking for and encourages communication. It shows respect for the patient's autonomy and gives them the opportunity to express themselves fully. Choice B may overwhelm the patient, Choice C disrupts the communication process, and Choice D may not align with the patient's intended communication. Patience and support are key in aiding a patient with aphasia.

Correct Answer: B

Rationale: The correct answer is B (126mg/dl) because a fasting plasma glucose level ≥126mg/dl is diagnostic of diabetes. The diagnostic criteria for diabetes include a fasting plasma glucose level ≥126mg/dl on two separate occasions. Choices A, C, and D are incorrect because they do not meet the diagnostic threshold for diabetes. A (90mg/dl) is within the normal range, C (115mg/dl) is elevated but not diagnostic, and D (180mg/dl) is too high but not necessary for diagnosis. It's crucial to understand the specific diagnostic criteria to accurately identify diabetes.
