Correct Answer: B

Rationale: The correct answer is to discontinue the IV infusion. The signs of redness and warmth at the IV site indicate phlebitis, an inflammation of the vein. Discontinuing the IV infusion is crucial to prevent further complications such as infection or thrombosis. Flushing the IV line with saline would not address the underlying issue of phlebitis. Applying a cold compress may provide temporary relief but does not address the cause. Increasing the IV flow rate can exacerbate the inflammation and should be avoided.

Correct Answer: B

Rationale: Bowel inflammation can reduce the absorption of oral medications, leading to decreased effectiveness. In this case, the decrease in the effectiveness of the arthritis medication could be attributed to impaired absorption due to bowel inflammation. Choices A, C, and D are incorrect because increased activity level, long-term use of the medication, and history of dehydration are not directly associated with a decrease in medication effectiveness related to absorption issues.

Correct Answer: D

Rationale: The correct answer is D because clients can change their living will at any time as long as they are mentally competent. Choice A is incorrect because relying solely on family to make decisions may not align with the client's wishes. Choice B is incorrect because a living will can address various situations, not just loss of consciousness. Choice C is incorrect because the client should be the primary decision-maker regarding their living will, not the family.

Correct Answer: C

Rationale: In this scenario, the nurse should explain the benefits of the surgery to the client. By providing more information, the client may reconsider their decision after understanding the positive impact the surgery could have on their vision. Proceeding with the surgery against the client's wishes (Choice A) is not ethical and goes against the principle of autonomy. While documenting the refusal and informing the surgeon (Choice B) is important for the client's medical record, it is crucial to first try to educate the client about the benefits. Simply respecting the client's decision (Choice D) without attempting to provide more information may not be in the client's best interest.

Correct Answer: B

Rationale: The correct first action for the nurse to take when receiving a report of a client's blood pressure reading of 160/95 is to recheck the blood pressure. Rechecking the blood pressure ensures the accuracy of the reading before making any further decisions or interventions. Notifying the provider (Choice A) can be considered after confirming the blood pressure reading. Administering antihypertensive medication (Choice C) should not be done based solely on one reading without verification. Documenting the blood pressure in the chart (Choice D) should also come after confirming the accuracy of the reading to avoid recording incorrect information.
