Correct Answer: C

Rationale: The correct answer is C because it provides accurate information about a specific risk factor related to a particular ethnic group. American-Indian women do have a higher rate of ovarian cancer than the general population, making it crucial for the nurse to be aware of this when teaching about cancer risk factors. A is incorrect as it discusses breast cancer and not ovarian cancer. B is incorrect as it mentions esophageal cancer, which is not the specific focus of the question. D is also incorrect as it makes a general statement about cancer, heart disease, and stroke in ethnic groups without providing specific information about ovarian cancer in American-Indian women.

Correct Answer: A

Rationale: The correct answer is A because informed consent documents must provide participants with an explanation of potential risks and benefits to ensure they fully understand what they are agreeing to. This helps participants make an informed decision about participating. Option B is incorrect because using medical terminology can actually increase misunderstanding; lay terms are recommended. Option C is incorrect as it is essential to include a statement on protecting anonymity and confidentiality to ensure participant privacy. Option D is incorrect as explaining the cost of the study is not a necessary component of informed consent.

Correct Answer: A

Rationale: The correct answer is A because it specifies a measurable and achievable goal related to improving cardiac function through physical activities. It follows the SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound). Option B does not provide a specific outcome, while Option C focuses on pharmaceutical approaches rather than outcomes. Option D is unrelated to the goal of improving outcomes for heart failure patients. Thus, option A is the most appropriate choice for a well-defined and relevant outcome for the care of heart failure patients.

Correct Answer: D

Rationale: The correct answer is D because feedback is an essential component of the communication process. Feedback allows the receiver to respond to the sender, indicating understanding or seeking clarification. This two-way interaction is crucial for effective communication. In contrast, choice A is incorrect as communication components are interdependent, not mutually exclusive. Choice B is also incorrect as communication is often non-linear and involves feedback loops. Choice C is incorrect because communication involves various elements beyond just the sender and the receiver, such as context, message, and noise.

Correct Answer: B

Rationale: The correct answer is B: Florence Nightingale. Occupational health nursing shares beliefs with Florence Nightingale as she emphasized the importance of proper sanitation, hygiene, and preventive care in nursing practice. Nightingale's focus on maintaining a healthy environment aligns with the core principles of occupational health nursing. Lillian Wald is known for her work in public health nursing, Clara Barton for founding the American Red Cross, and Mary Seacole for her contributions during the Crimean War. While these pioneers made significant contributions to nursing, their beliefs and focus areas differ from those of occupational health nursing.
