Correct Answer: A

Rationale: A registered nurse is responsible for a group of patients from their admission to their discharge. This responsibility encompasses assessing patient needs, formulating care plans, administering medications, monitoring patient progress, and coordinating with other members of the healthcare team. Choice B is not entirely accurate because, even though nurses often work with nursing aides, the nurses themselves hold the ultimate responsibility for the overall care of the patient. Choices C and D are incorrect as they depict an incomplete and inaccurate representation of a nurse's role, which extends beyond administrative duties and equipment maintenance to primarily focus on direct patient care.

Correct Answer: A

Rationale: The correct answer is A: 'It produces an anesthetic effect.' Hot compresses can help alleviate pain by producing an anesthetic effect, which numbs the area. Choice B is incorrect because a hot compress does not directly increase nutrition in the blood to promote wound healing. Choice C is also incorrect because a hot compress primarily aids in pain relief rather than increasing oxygenation to the tissues for enhanced healing. Choice D is incorrect because hot compresses typically lead to vasodilation, not vasoconstriction, which aids in promoting blood flow rather than preventing infection. Safe and effective patient care relies on actions based on established nursing protocols that consider both the immediate and long-term needs of the patient.

Correct Answer: C

Rationale: Common risk factors for lifestyle-related diseases typically include aspects of one's lifestyle that can be modified or controlled, such as physical activity, smoking habits, and nutrition. These factors can be changed to prevent or manage lifestyle-related diseases. Genetics, on the other hand, is not a modifiable risk factor, meaning it cannot be changed or controlled. Therefore, it is not considered a common risk factor for lifestyle-related diseases. Understanding the modifiable risk factors for these diseases allows for better prevention and management strategies, and helps reduce the risk of complications.

Correct Answer: C

Rationale: After a lobectomy, a chest tube is typically inserted to drain fluids and blood that may have accumulated post-operatively. This tube helps to prevent complications, such as infections or pneumonia, and aids in patient recovery. While a chest tube may aid in preventing a mediastinal shift (Choice A), promoting chest expansion of the remaining lung (Choice B), and removing air in the lungs to promote lung expansion (Choice D), these are not the primary reasons for its use after a lobectomy. Therefore, Choices A, B, and D are incorrect.
