Correct Answer: B

Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.

Correct Answer: A

Rationale: The correct answer is A: Encourage the patient to perform as many self-care activities as possible. For a patient who has had a stroke, promoting independence and engaging in self-care activities help maintain mobility and foster a sense of autonomy. Choices B, C, and D are incorrect because providing assistance with a bed bath, coordinating with physical therapy for gait training, or advising bed rest without indications may not be the best interventions for promoting optimal recovery and independence in a stroke patient.

Correct Answer: D

Rationale: The most critical action for the LPN/LVN to take in this situation is to ask security to ensure the room is safe. This step is crucial to prevent any further harm to the unconscious client or others. While it is important to assess the client's condition, ensuring safety takes precedence. Calling security from the room may expose the LPN/LVN to potential danger without confirming the safety of the environment first. Finding out if anyone else is in the room can wait until safety is established to avoid unnecessary risks.

Correct Answer: B

Rationale: The correct answer is B. When documenting the quality of pain, it is essential to record the client's description of how the pain feels in their own words. Choice A simply states the intensity of pain but does not describe its quality. Choices C and D provide information related to aggravating factors and associated symptoms, respectively, but they do not describe the quality of pain. Therefore, choice B, which describes the pain as a dull ache in the stomach, is the most appropriate statement to document for assessing the quality of the client's pain.
