Correct Answer: C

Rationale: In hyperparathyroidism, there is excessive production of parathyroid hormone, leading to increased calcium resorption from the bones. This process causes bone pain, making choice C the correct answer. Tetany (choice A) is associated with hypocalcemia, not hyperparathyroidism. Hypocalcemia (choice B) is the opposite condition of hyperparathyroidism, where blood calcium levels are elevated. Hypotension (choice D) is not a typical symptom of hyperparathyroidism.

Correct Answer: B

Rationale: The first action should be to discontinue the intravenous line to prevent further complications such as infection or thrombophlebitis. Starting a new IV in the right hand is not the priority as addressing the current issue is important. Completing an incident record can be done after addressing the immediate concern of the IV site. Placing a warm washcloth over the site does not address the red streak and tenderness, which may indicate an infection that requires discontinuation of the IV line.

Correct Answer: B

Rationale: The correct answer is to take the regular insulin first, then the NPH insulin. Regular insulin should be drawn up before NPH insulin to prevent contamination of the regular insulin vial with the longer-acting insulin. Choice A is incorrect as it suggests taking the NPH insulin first, which is not the recommended practice. Choice C is incorrect because the order of drawing up insulin does matter to prevent contamination. Choice D is not the most appropriate action in this scenario, as the nurse should provide clear instructions to the client based on best practices.

Correct Answer: D

Rationale: The correct answer is to instruct the client to inspect their feet daily for any cuts or sores. This is crucial for individuals with diabetes as they are at a higher risk of developing foot problems. Soaking feet daily can lead to skin breakdown and infections, making choice A incorrect. Tight-fitting shoes can cause pressure points and increase the risk of foot injuries, so choice B is incorrect. Applying lotion between the toes can create a moist environment, increasing the risk of fungal infections, making choice C incorrect.

Correct Answer: C

Rationale: Confidentiality is the ethical principle involved in protecting a patient's privacy and ensuring that personal information is not shared inappropriately. Fidelity refers to being faithful to commitments and keeping promises, not directly related to privacy and confidentiality. Beneficence involves doing good for the patient, and justice pertains to fairness and equal treatment, but they are not directly related to protecting privacy and confidentiality.
