Choice B is a good practice to prevent oral fungal infections associated with inhaled corticosteroids, not typically with albuterol. Choice D is important for proper inhaler technique, but the primary step before inhaling is shaking the inhaler to ensure the medication is well mixed.

Therefore, including all these aspects in the care plan can help support the client's recovery. Choice D, 'All of the above,' is the correct answer because all the options are important components of a holistic care plan for depression.

Rationale: Encouraging early ambulation is crucial following a total hip replacement surgery as it helps prevent complications such as deep vein thrombosis (DVT) by promoting circulation. Early ambulation also aids in preventing pneumonia, muscle atrophy, and pressure ulcers. Applying ice to the surgical site may help with pain and swelling, but it is not as critical in preventing complications as early ambulation. While monitoring the surgical site for signs of infection is important, it is not as crucial in preventing postoperative complications compared to early ambulation. Administering pain medication as prescribed is essential for comfort and pain management but does not directly prevent postoperative complications like early ambulation does.
