Correct Answer: C

Rationale: The 42-year-old client who is 50 pounds overweight is at the highest risk for developing diabetes. Excess weight is a significant risk factor for diabetes as it can lead to insulin resistance and metabolic abnormalities. Choices A, B, and D are also risk factors for diabetes, but being overweight has a stronger association with the development of the condition compared to lack of exercise, excessive alcohol consumption, or smoking.

Correct Answer: C

Rationale: All staff members should document the care they provided as part of their accountability and to ensure accurate and comprehensive records. In healthcare settings, it is essential for all staff to document the care they deliver for continuity of care and legal purposes. The registered nurse may sign off on the documentation for oversight purposes, but the responsibility of documenting care extends to all staff involved in patient care. Choices A and B incorrectly limit the responsibility to specific roles, while choice D inaccurately suggests that only the registered nurse signs off on the documentation, overlooking the importance of comprehensive documentation by all staff members involved.

Correct Answer: B

Rationale: An average full-term infant requires about 120 calories per kilogram per day at 1-2 months old. This amount is essential for their growth and development during this critical stage. Choices A, C, and D are incorrect as they provide calorie amounts that are either too high or too low for an average full-term infant at 1-2 months old, which could potentially lead to health issues or inadequate nutrition.

Correct Answer: D

Rationale: The correct answer is D because taking every chance to engage with the public about nursing allows for the improvement of nursing's image and the promotion of the profession. Choice A is incorrect as uniforms should reflect professionalism rather than personality. Choice B is not directly related to improving nursing's image. Choice C, while important, does not directly address improving the image of nursing through public engagement.

Correct Answer: B

Rationale: The best explanation for the continued nursing shortages in some states despite an overall projected surplus by 2030 is workforce availability. This factor directly impacts the number of nurses available in certain regions. Choice A about healthcare legislation affecting nursing salaries does not directly address the availability of nurses. Choice C is incorrect as the aging of the baby boomers would typically imply an older nursing workforce instead of a younger one. Choice D regarding population declines does not necessarily relate to the availability of nurses in specific states.
