A resident returns to the long-term care center after a right total hip replacement. The nurse should reinforce teaching for maintaining which of the following postoperative leg positions?

Choice A reason: This statement is incorrect because it suggests that higher oxygen levels trigger breathing, which is not the case in hypoxic drive.

Choice B reason: While carbon dioxide levels do influence breathing, this statement is not accurate in the context of hypoxic drive, which is specifically about oxygen levels.

Choice C reason: This choice is incorrect because the client does notice the need to breathe, but the trigger is low oxygen rather than high carbon dioxide levels.

Choice D reason: This is correct. In clients with COPD, chronic high levels of carbon dioxide can lead to a reliance on low oxygen levels to stimulate breathing.

Choice A reason: Nail polish should generally be removed before surgery to allow the pulse oximeter to function properly, but it is not as critical as removing dentures.

Choice B reason: Dentures should be removed before surgery to prevent aspiration and other complications during anesthesia.

Choice C reason: Giving dentures to the family is appropriate after they have been removed, so this does not warrant intervention.

Choice D reason: It is standard procedure to get a new set of vital signs before surgery, so this statement is correct and does not warrant intervention.
