Correct Answer: A

Rationale: The correct answer is A: Twitching. Hypocalcemia often presents with neuromuscular irritability, leading to manifestations such as twitching. Trousseau's sign is actually a positive indicator of hypocalcemia, not negative, making choice B incorrect. Hypoactive bowel sounds are not typically associated with hypocalcemia, making choice C incorrect. Similarly, hypoactive deep tendon reflexes are not a common finding in hypocalcemia, making choice D incorrect.

Correct Answer: D

Rationale: For a patient with acute hypernatremia, the nurse should include interventions like reducing free water losses, correcting sodium levels slowly, monitoring neurologic status, and ensuring adequate fluid intake. Conducting frequent neurologic checks is essential in assessing the patient's neurological status and detecting any changes promptly. Therefore, this action should not be excluded from the plan of care. Choices A, B, and C are not directly related to managing acute hypernatremia and can be safely excluded from the plan of care. Reducing IV access, limiting length of visits, and restricting fluids to 1500 mL per day are not appropriate actions for managing acute hypernatremia.

Correct Answer: B

Rationale: The correct first action for the nurse to take is to close the documentation program on the computer to prevent further unauthorized access to the client's medical information. Choice A is incorrect because the immediate concern is to secure the information first. Choice C, while important, can be addressed after securing the information. Choice D, finding out which staff member left the program open, is not the immediate priority when patient confidentiality is at risk.

Correct Answer: B

Rationale: The main purpose of quality improvement in healthcare is to improve patient outcomes by enhancing the quality and safety of healthcare services. Choice A is incorrect because the goal is not to increase healthcare costs but to optimize resources and provide cost-effective care. Choice C is incorrect as the aim is to increase patient satisfaction through better outcomes. Choice D is incorrect as the objective is to reduce hospital stays by improving care efficiency and effectiveness.

Correct Answer: B

Rationale: Engaging in conversations about healthcare issues with a wide audience, including legislators, is a powerful way for a nurse to exert leadership and support the nursing profession. This action helps raise awareness, advocate for nursing-related matters, and contribute to positive changes in healthcare policies. Choice A, joining a local professional organization, is beneficial but may not have the same broad impact as engaging in public discourse. Choice C, registering to vote, is important for civic engagement but does not directly relate to exerting leadership in supporting the nursing profession. Choice D, learning about the healthcare system, is valuable for personal development but does not directly address exerting leadership in supporting the nursing profession.
