Correct Answer: B

Rationale: The correct answer is B because it acknowledges the patient's behavior is likely due to the stroke affecting his inhibitions. Finding a male assistant respects both the patient's dignity and the nursing assistant's comfort. Choice A is inappropriate as physical violence is never an acceptable response. Choice C lacks empathy and understanding of the situation. Choice D minimizes the seriousness of the behavior and fails to address the issue. B is the best option for promoting a safe and respectful environment for both the patient and staff.

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: 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: Step 1: Orthopnea is a classic symptom of congestive heart failure (CHF) due to fluid accumulation in the lungs when lying flat. Step 2: This symptom occurs because when lying down, the fluid redistributes, making it harder to breathe. Step 3: Fever (choice B) is not typically associated with CHF unless there is an underlying infection. Step 4: Weight loss (choice C) is more indicative of conditions like cancer or malnutrition, not CHF. Step 5: Calf pain (choice D) is more commonly associated with deep vein thrombosis, not CHF. Summary: Orthopnea is the best assessment finding indicating CHF, while the other choices are more likely related to different health conditions.

Correct Answer: A

Rationale: The correct answer is A because observing for signs of brain injury is crucial in assessing a possible skull fracture. Signs may include altered mental status, headache, nausea, vomiting, and unequal pupil size. Choice B is incorrect as hemorrhaging from the oral cavity may not always be present in skull fractures. Choice C is incorrect as elevating the foot of the bed is not recommended for a possible skull fracture. Choice D is incorrect as decreased intracranial pressure and temperature are not typical symptoms of a skull fracture.
