Correct Answer: D

Rationale: The correct answer is 'To be aware of the role of the licensed nurse.' Nurse practice acts outline the scope of practice for nurses, defining what constitutes nursing practice and the role of licensed nurses. Choice A is incorrect because hospital and long-term care facility policies are institution-specific and not typically covered in the nurse practice act. Choice B is incorrect as the scope of practice for nurses is a part of the nurse practice act, but it's not the sole purpose for a nurse to refer to it. Choice C is incorrect as health care policies in a state are governed by other legislative acts, not the nurse practice act.

Correct Answer: A

Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.

Correct Answer: C

Rationale: When assessing a client's risk for elimination impairment, family history is the least relevant factor to consider. Current medications can affect elimination functions through side effects, ambulation abilities can impact mobility to access toileting facilities, and hydration status directly influences urinary output and bowel function. Family history, although providing some context, does not have a direct impact on the client's current risk of elimination impairment.

Correct Answer: A

Rationale: Monitoring an intravenous infusion involves assessing for complications, adjusting the flow rate, and monitoring the client's response, which requires the knowledge and skills of a licensed nurse (RN or LPN). Tasks that can be delegated to nursing assistants or unlicensed assistive personnel include assisting a client to the bathroom, offering fluids, and recording fluid intake. These activities are within the scope of practice for UAPs as they do not involve the specialized knowledge and training needed for intravenous infusion monitoring.

Correct Answer: B

Rationale: The correct answer is to promote healthy nutritional practices. This goal focuses on preventive measures to address the client's nutritional risk. Providing oxygen (Choice A) is not directly related to addressing nutritional problems. Treating complications of malnutrition (Choice C) involves addressing the consequences rather than preventing or managing the nutritional problems. Increasing weight (Choice D) would only be appropriate if the client is underweight; it does not address the broader aspect of promoting overall healthy nutritional practices.
