Correct Answer: A

Rationale: In hyperparathyroidism, there are already elevated calcium levels in the body. Therefore, clients should avoid high-calcium foods like milk to prevent further increase in calcium levels. Bananas, spinach, and processed meats do not have significant calcium content and do not need to be avoided specifically in hyperparathyroidism.

Correct Answer: A

Rationale: The correct answer is A: Increased risk of heart disease and stroke. Uncontrolled blood glucose levels in clients with diabetes mellitus (DM) can lead to cardiovascular complications, such as heart disease and stroke. High blood glucose levels can damage blood vessels over time, increasing the risk of atherosclerosis and cardiovascular events. Choices B, C, and D are incorrect because uncontrolled blood glucose levels do not improve wound healing, reduce the need for medication, or decrease the risk of infection. In fact, uncontrolled blood glucose levels can impair wound healing, require more medications to manage symptoms, and increase the risk of infections due to compromised immune function.

Correct Answer: C

Rationale: The correct instruction for a client with type 2 diabetes mellitus regarding foot care is to inspect their feet daily for any cuts or sores. This practice helps in early detection of potential issues like cuts, sores, or infections, which can be challenging to heal due to poor circulation in diabetes. Choice A is incorrect because soaking feet in hot water can lead to burns or skin damage, especially for individuals with diabetes who may have reduced sensation. Choice B is incorrect because going barefoot increases the risk of injuries and infections for individuals with diabetes. Choice D is incorrect because using a heating pad can also impair sensation, increasing the risk of burns or injuries for diabetic individuals.

Correct Answer: C

Rationale: The correct answer is C. Nurses advocate for patients by ensuring that they receive the necessary care and by protecting their rights. This involves speaking up for patients, ensuring they are treated with respect, and helping them access appropriate healthcare services. Option A, providing information for informed decision-making, is an important aspect of nursing care but not the central role of advocacy. Option B, communicating patients' needs to the healthcare team, is essential but more focused on teamwork and collaboration. Option D, helping patients navigate the healthcare system and access resources, is valuable but not the primary definition of advocacy in nursing.

Correct Answer: D

Rationale: Precautions for clients receiving TPN include placing the solution on an IV pump to control the rate, monitoring blood glucose levels to detect hyperglycemia, and monitoring intake and output to assess fluid balance. Changing the IV tubing every three days is not a standard precaution for clients receiving TPN via a subclavian line.
