Correct Answer: B

Rationale: The correct answer is to discontinue the infusion. The symptoms described - pain, redness, and warmth along the vein - are indicative of phlebitis, which is inflammation of the vein. Continuing the infusion can lead to further complications. Flushing the IV line, elevating the limb, or applying a cold compress do not address the underlying issue of phlebitis and may not be sufficient to resolve the problem. Therefore, the priority action is to discontinue the infusion to prevent worsening of the condition.

Correct Answer: B

Rationale: The correct answer is B: Decrease in elasticity. As individuals age, their skin tends to lose elasticity, becoming less flexible. This results in wrinkles and sagging skin. Option A, increase in oil production, is not typically an expected integumentary change in older adults. Option C, increase in pigmentation, may occur due to sun exposure or age spots but is not a universal change. Option D, decrease in moisture levels, is not a primary integumentary change associated with aging.

Correct Answer: B

Rationale: The correct first action for the nurse to take when a client reports pain and tenderness at the site of an indwelling urinary catheter is to notify the provider. Pain and tenderness at the catheter site may indicate infection, and the healthcare provider needs to be informed for further assessment and appropriate interventions. Irrigating the catheter with normal saline (Choice A) should not be the initial action without consulting the provider first. While assessing for signs of infection (Choice C) is important, notifying the provider takes precedence. Administering prescribed antibiotics (Choice D) should only be done based on the provider's orders after assessment and confirmation of infection.

Correct Answer: B

Rationale: The correct answer is B: 'Wear shoes at all times.' This instruction is crucial for clients with diabetes as it helps protect the feet from potential injuries. Choice A of soaking feet in warm water daily can lead to skin issues and should be avoided. Cutting toenails in a rounded shape, as mentioned in choice C, can increase the risk of ingrown toenails. While inspecting the feet weekly, as in choice D, is important, wearing shoes at all times is a more preventative measure to avoid foot injuries in diabetic clients.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid smoking and open flames near oxygen.' This information is crucial to prevent fire hazards when using home oxygen therapy. Smoking and open flames near oxygen can lead to serious accidents. Choice A is incorrect because increasing the oxygen flow rate during activity without healthcare provider guidance can be dangerous. Choice C is incorrect as oxygen tanks should be stored in a well-ventilated area, not necessarily warm and dry. Choice D is incorrect as oxygen should not be turned off and on by the client, as it can affect the therapy's effectiveness and cause safety issues.
