Correct Answer: A

Rationale: The correct answer is A because oral feeding of a stable child is a task that can be safely delegated to a UAP. This task does not require nursing assessment or clinical judgment. Choice B involves assessment, which requires the nurse's clinical judgment. Choice C involves recording client goals during staff rounds, which may require interpretation and understanding of the goals set. Choice D involves evaluating a client's pain following medication administration, which requires assessment and clinical judgment by a nurse.

Correct Answer: C

Rationale: The correct answer is C: Redness, warmth, and swelling at the site of infection. These signs are typical indications of a localized infection, representing inflammation and the body's immune response to the pathogen. Fever (choice A) is a systemic response and not specific to a localized infection. Elevated white blood cell count (choice B) can be seen in both localized and systemic infections. Chills and shivering (choice D) are more related to the body's response to fever and not specifically indicative of a localized infection.

Correct Answer: C

Rationale: Protein is the correct answer as it is essential for tissue growth and repair. Proteins are composed of amino acids, the building blocks of body tissues. While vitamins D and E have important roles in the body, they are not primarily responsible for tissue growth and repair. Fats are crucial for various bodily functions, like providing energy, but they are not the primary component involved in tissue growth and repair.

Correct Answer: B

Rationale: Keeping the client's hip aligned with the knees abducted is crucial to prevent dislocation of the prosthesis, which is a priority immediately after total hip replacement surgery. This position helps maintain the stability of the new hip joint. Encouraging the client to use a walker or cane (Choice A) is important but not as critical as ensuring proper hip alignment. Teaching the client to sit on the side of the bed before standing (Choice C) is a good practice but not as essential as maintaining hip alignment. Monitoring urinary flow via an indwelling catheter (Choice D) is not directly related to preventing complications immediately after a total hip replacement.

Correct Answer: A

Rationale: Hyperosmotic agents primarily work by reducing cerebral edema, dehydrating the brain, and drawing fluids from extravascular spaces into the plasma. However, they do not have a direct effect on reducing brain metabolism or systemic blood pressure. Therefore, the correct answer is A. Choice B is correct as hyperosmotic agents do help in reducing cerebral edema. Choice C is accurate as hyperosmotic agents dehydrate the brain. Choice D is also true as these agents draw fluids from extravascular spaces into the plasma.
