Correct Answer: D

Rationale: The correct answer is 'D: Transporting a client to x-ray.' This task is appropriate for delegation to assistive personnel as it involves transferring the client safely from one location to another, which does not require the specialized skills of a healthcare provider. Adjusting the flow rate of the client's oxygen tank (Choice A) involves making clinical decisions that should be done by a licensed healthcare provider. Collecting a urine sample (Choice B) and measuring the client's pain level (Choice C) require critical thinking and assessment skills that are typically within the scope of practice of licensed healthcare providers, not assistive personnel.

Correct Answer: A

Rationale: The correct answer is A: 'Regulate blood glucose levels.' Administering insulin to a patient with diabetes helps regulate blood glucose levels by facilitating the uptake of glucose into cells, thereby lowering high blood sugar levels. This process aims to prevent hyperglycemia and its associated complications. Choice B, 'Increase metabolism,' is incorrect as the primary role of insulin is not to increase metabolism directly. Choice C, 'Prevent complications,' is partially correct as regulating blood glucose through insulin administration does help prevent complications associated with uncontrolled diabetes, but it is not the primary purpose. Choice D, 'Promote insulin sensitivity,' is incorrect as insulin itself is administered to compensate for the lack of endogenous insulin in diabetic patients, rather than to promote sensitivity to it.

Correct Answer: C

Rationale: The correct answer is to instruct the client to sit quietly for 5 minutes before measuring their blood pressure. This allows the body to relax and stabilize, leading to a more accurate reading. Choice A is incorrect because using a cuff that is too loose can result in inaccurate readings. Choice B is incorrect as the cuff should be placed directly on the bare skin. Choice D is incorrect as using the same arm for each reading is important for consistency in monitoring, but sitting quietly before measuring is crucial for accuracy.

Correct Answer: C

Rationale: The correct answer is to encourage weight-bearing exercises to prevent bone loss in clients with osteoporosis. Weight-bearing exercises help to strengthen bones and reduce the risk of fractures. Increasing calcium intake (Choice A) is important for bone health but is not the priority intervention for preventing bone loss in osteoporosis. Applying heat to affected joints (Choice B) may help with stiffness but does not address the underlying bone loss in osteoporosis. Limiting fluid intake (Choice D) is not relevant to managing osteoporosis and preventing bone loss.

Correct Answer: A

Rationale: When a patient refuses a newly opened fentanyl patch, the nurse should ask another nurse to witness the disposal of the new patch. This action ensures accountability, proper protocol, and prevents any potential diversion or misuse of the medication. Disposing of the patch in a sharps container (Choice B) is not sufficient as it does not address the need for witness accountability. Sending the patch back to the pharmacy (Choice C) may not be appropriate without proper documentation and witness. Simply documenting the refusal and removing the patch (Choice D) may lack the necessary verification of proper disposal.
