Correct Answer: C

Rationale: The correct answer is C: Decrease in moisture levels. In older adults, there is a reduction in oil production, leading to decreased moisture levels in the skin. This change can result in dry skin and increased risk of skin issues. The other choices are incorrect because in older adults, skin turgor tends to decrease, subcutaneous fat may decrease, and oil production typically decreases rather than increases.

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: When a client reports pain and redness at the site of a peripheral IV, indicating signs of phlebitis, the nurse's initial action should be to discontinue the IV line. This helps prevent further complications and ensures patient safety. Applying a cold compress (Choice A) may provide temporary relief but does not address the underlying issue. Notifying the provider (Choice C) is important but not the initial step. Increasing the IV flow rate (Choice D) can exacerbate the inflammation and should be avoided.

Correct Answer: D

Rationale: The correct answer is D: Chronic conditions. Chronic conditions, such as diabetes or immune suppression, can compromise the immune system, making individuals more susceptible to infections. Frequent handwashing (Choice A) is actually a protective measure against infections. Increased mobility (Choice B) and high blood pressure (Choice C) are not directly associated with an increased risk for infections.

Correct Answer: B

Rationale: The correct answer is to discontinue the infusion. Pain, redness, and warmth at the IV site are signs of phlebitis, which is inflammation of the vein. Continuing the infusion can further irritate the vein and lead to complications. Increasing the IV flow rate would exacerbate the issue by delivering more irritants to the vein. Elevating the limb and applying a cold compress are not the appropriate interventions for phlebitis, as discontinuing the infusion is crucial to prevent further harm.
