The client with chronic obstructive pulmonary disease (COPD) is being educated about lifestyle changes. Which statement by the client indicates a need for further teaching?

Correct Answer: C

Rationale: The correct answer is C. Clients with COPD should limit alcohol intake, not just to weekends, to effectively manage their condition. Excessive alcohol consumption can worsen respiratory symptoms and interfere with medications. Choices A, B, and D are all appropriate and beneficial for clients with COPD. Salt intake reduction helps in managing fluid retention and blood pressure. Regular exercise improves lung function and overall health. Monitoring blood pressure is crucial for individuals with COPD as hypertension is a common comorbidity.

Correct Answer: C

Rationale: At 0100 on the client's second postoperative night, the nurse should address the client's inability to sleep. Providing a prescribed PRN sedative-hypnotic is appropriate in this situation to help the client rest. Choice A is incorrect because leaving the room and closing the door does not directly address the client's sleep concern. Choice B is not the priority at this moment since the client's main issue is insomnia, not pain. Choice D, while encouraging a non-stimulating activity, does not provide immediate relief for the client's sleeplessness as a sedative-hypnotic would.

Correct Answer: B

Rationale: Edema, indicated by 2+ edema of fingers and hands, can impair blood flow and peripheral perfusion, leading to reduced oxygen saturation readings on a pulse oximeter. High blood pressure (choice A) would not directly affect oxygen saturation readings. Radial pulse volume (choice C) and capillary refill time (choice D) are more related to assessing circulation rather than contributing significantly to oxygen saturation readings.

Correct Answer: D

Rationale: The correct intervention is to give the missed dose at 1300 and adjust the schedule to administer daily at 1300. This approach ensures that the client receives the correct total daily dose of levofloxacin. Choice A is incorrect because contacting the healthcare provider and completing a medication variance form would not address the immediate need to administer the missed dose. Choice B is incorrect as administering the missed dose at 1300 and resuming the 0900 schedule the next morning would result in a missed dose for that day. Choice C is not the best course of action as notifying the charge nurse and completing an incident report should come after addressing the immediate need to administer the missed dose and adjusting the schedule for future doses.

Correct Answer: C

Rationale: After a client experiences severe coughing following nasogastric tube feedings, it is crucial to verify proper tube placement. Checking the pH of fluid withdrawn from the tube helps confirm the tube's correct positioning. Option A is incorrect because further action is necessary to ensure the client's safety. Option B is inappropriate as it suggests stopping the feeding without assessing the tube's placement. Option D is incorrect as injecting air into the tube may lead to further complications if the tube is not positioned correctly.
