Correct Answer: A

Rationale: The correct answer is A: Where is the pain located? In the PQRST mnemonic, "P" stands for provocation, "Q" for quality, "R" for region/radiation, "S" for severity, and "T" for timing. The question "Where is the pain located?" corresponds to the "R" component, which is region/radiation. This question helps the nurse identify the specific area where the pain is localized, which can provide valuable information for diagnosis. Explanation of other choices: B: What causes the pain? This question relates more to the "P" component, which is provocation, rather than the region/radiation aspect. C: Does it come and go? This question pertains to the "T" component, which is timing, focusing on the pattern of the pain rather than the specific location. D: What does the pain feel like? This question is more aligned with the "Q" component, which is quality,

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 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.

Correct Answer: D

Rationale: The correct answer is D: 60 seconds. This is because the area must be cleaned for at least 60 seconds to effectively disinfect the skin and reduce the risk of infection during venipuncture. Cleaning for shorter durations (5, 10, or 30 seconds) may not be sufficient to achieve proper disinfection. Thoroughly cleaning the area for a full minute ensures that the alcohol has enough time to kill bacteria and pathogens on the skin, making it safer for the venipuncture procedure. Shorter cleaning times may leave pathogens behind, increasing the risk of contamination and infection.

Correct Answer: C

Rationale: The correct answer is C: Pneumonia. Early postoperative ambulation helps prevent pneumonia by promoting lung expansion, increasing oxygenation, and preventing atelectasis. A: Increased peristalsis is unrelated to ambulation. B: Coughing is important for airway clearance but not directly related to ambulation. D: Wound healing is influenced by various factors, but ambulation primarily impacts respiratory function.
