Correct Answer: B

Rationale: Choice B is correct because nurses can develop effective leadership skills by actively engaging as good leaders and reflecting on their existing leadership qualities and areas for improvement. This process of self-assessment and continuous improvement is crucial in becoming a successful leader. Choice A is incorrect as leadership traits can be learned through experience and reflection rather than being impossible to acquire from a book. Choice C is incorrect as effective leadership involves focusing on long-term goals and strategies, not just daily activities. Choice D is incorrect because while seizing leadership opportunities is important, it should be done strategically and with a solid foundation of experience in nursing to ensure successful leadership outcomes.

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: 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.

Correct Answer: A

Rationale: Trousseau's sign is a clinical indicator of hypocalcemia, characterized by carpal spasm when a blood pressure cuff is inflated above systolic pressure and maintained for a few minutes. This occurs due to increased neuromuscular irritability associated with low serum calcium levels. Homans' sign is used to assess for deep vein thrombosis and involves calf pain upon dorsiflexion of the foot. Hegar's sign is a softening of the lower uterine segment seen in pregnancy, while Goodell's sign is softening of the cervix also seen in pregnancy. Therefore, in this scenario, the correct assessment related to hypocalcemia would be Trousseau's sign.

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.
