Correct Answer: A

Rationale: In a patient admitted with diabetic ketoacidosis, the initial priority is to address dehydration and electrolyte imbalances. Infusing 1 liter of normal saline per hour helps correct hypovolemia and restore electrolyte balance, making it the first essential step in managing diabetic ketoacidosis. Sodium bicarbonate is not routinely recommended in treating diabetic ketoacidosis and should not be given routinely as it may worsen the acidosis. Administering regular insulin and starting an insulin infusion are important but should come after fluid resuscitation to stabilize the patient's condition.

Correct Answer: D

Rationale: The correct action the nurse should add to the client's plan of care is to have a tongue depressor available at the client's bedside. This is important during a seizure to prevent the client from biting their tongue. Placing the client laterally helps maintain a clear airway and prevents aspiration, making choice C a good practice during seizure activity. Using restraints during a seizure can cause injuries and should be avoided, making choice B incorrect. Wrapping blankets around all four sides of the bed is unnecessary for seizure management and does not contribute to the client's safety during a seizure, making choice A incorrect.

Correct Answer: A

Rationale: After receiving aspart (NovoLog) insulin, which has a rapid onset, it is crucial to monitor the patient for symptoms of hypoglycemia during the peak action time. Typically, the peak action of aspart insulin occurs around 2 hours after administration. Therefore, the nurse should be most vigilant for hypoglycemia symptoms at 10:00 AM. Choice B (12:00 PM) is incorrect as it falls after the expected peak action time. Choices C (2:00 PM) and D (4:00 PM) are also incorrect because the peak action time of aspart insulin typically occurs earlier, around 2 hours post-administration.

Correct Answer: D

Rationale: Motivation is the driving force that compels individuals to strive to find the best way to do their job. It encompasses determination, enthusiasm, and a proactive approach to continuously improve and excel in their work. Being motivated is essential for individuals in any profession to seek innovative solutions, achieve excellence, and make a meaningful impact. Punctuality, while important, refers to being on time rather than the drive to find the best way to do a job. Strictness relates to enforcing rules or discipline, not necessarily to seeking the best way. Honesty is about truthfulness and integrity, which are crucial but not directly related to the pursuit of excellence in job performance.

Correct Answer: B

Rationale: The correct answer is B: 'Mentor and educator for new nurses.' A nurse preceptor plays a crucial role in mentoring and educating new nurses. They provide guidance, support, and practical knowledge to help new nurses transition smoothly into their roles. While preceptors may have supervisory responsibilities during the orientation period, their primary focus is on supporting the professional development of new nurses, rather than supervising all nursing staff, directing nursing services, or coordinating patient care. Choice A is incorrect because a nurse preceptor does not supervise all nursing staff but focuses on new nurses. Choice C is incorrect as the role of a director of nursing services involves overall management and leadership of nursing services. Choice D is incorrect as a coordinator of patient care is responsible for organizing patient care activities, not specifically focused on mentoring new nurses.
