Correct Answer: C

Rationale: The correct answer is C: Reassess the patient's pain level in 30 minutes. This is the priority action as it allows the nurse to evaluate the effectiveness of the acetaminophen in relieving the patient's headache. By reassessing the pain level, the nurse can determine if the medication is working or if further intervention is needed. A: Eliminating the headache from the care plan is not appropriate as the patient's comfort and pain relief should be a priority. B: Directing the nursing assistive personnel to inquire if the headache is relieved is not thorough assessment and does not provide direct evaluation of the patient's pain level. D: Revising the plan of care may be necessary based on the reassessment, but it is not the immediate priority compared to evaluating the patient's response to treatment.

Correct Answer: D

Rationale: The correct answer is D because dysplasia refers to the alteration in the size, shape, and organization of differentiated cells. Dysplasia is an abnormal growth or development of cells that can be a precursor to cancer. It is characterized by changes in cell size, shape, and organization, which can be seen in Papanicolaou tests. Choice A is incorrect because it describes an undifferentiated tumor, not dysplasia. Choice B is incorrect as it describes hyperplasia, not dysplasia. Choice C is incorrect as it refers to metaplasia, not dysplasia. In summary, dysplasia is specifically about the abnormal changes in the appearance and organization of differentiated cells, making choice D the correct definition.

Correct Answer: C

Rationale: The normal range of hemoglobin in adult blood is typically between 12-18 g/dL. This range is the most common and widely accepted range based on clinical guidelines and research studies. Hemoglobin levels outside this range may indicate anemia or other health conditions. Choice A (7-11 mg) is too low for normal hemoglobin levels in adults and indicates severe anemia. Choice B (14-20 mg) is slightly higher and could be normal for some individuals, but generally, 12-18 g/dL is the standard range. Choice D (20-26 mg) is too high and may indicate dehydration or other medical conditions.

Correct Answer: A

Rationale: The correct answer is A because gathering and organizing needed supplies is a crucial step before performing a complex dressing change. By ensuring all necessary supplies are readily available, the nurse can streamline the process, minimize interruptions, and promote efficiency. This step also helps maintain aseptic technique and prevent the spread of infection. Deciding on goals and outcomes (B) is important but typically done as part of the care planning process, not immediately before a dressing change. Assessing the patient's readiness (C) is also important but can be done concurrently with gathering supplies. Calling for assistance (D) may be necessary in some situations, but it is not the immediate step required just before changing the dressing.

Correct Answer: B

Rationale: The correct answer is B: Encourage ambulation and liberal fluid. Encouraging ambulation can help in the movement of kidney stones and alleviate pain. Liberal fluid intake helps in flushing out kidney stones and preventing further stone formation. Incorrect options: A: Administering prescribed nephrotoxic drugs can worsen kidney function and exacerbate the pain. C: Observing aseptic principles when changing intake is important for infection prevention but not directly related to pain management for renal calculi. D: Providing a comfortable position can offer temporary relief but does not address the underlying cause of kidney stone pain.
