Correct Answer: D

Rationale: The aorta is not a vein; it is the main artery in the body that carries oxygenated blood from the heart to the rest of the body. In parenteral cannulation, major veins like the basilic vein, femoral vein, and subclavian vein are typically used for access. Therefore, the correct answer is the aorta, as it is an artery and not a vein used for cannulation.

Correct Answer: D

Rationale: In a complete spinal injury, there is total loss of motor and sensory functions below the level of the injury. This means that both motor (ability to move) and sensory (ability to feel) functions are affected. It is important to distinguish between complete and incomplete spinal injuries, as complete injuries result in the loss of all functions below the level of injury, while incomplete injuries allow for some preservation of motor or sensory functions.

Correct Answer: B

Rationale: The correct answer is B: 'Encouraging healthy behaviors.' Health promotion focuses on empowering individuals and communities to take control of their health by promoting healthy behaviors and lifestyles. This approach involves education, creating supportive environments, and advocating for policies that enhance well-being. It goes beyond simply treating illness or preventing diseases, emphasizing a proactive and holistic approach to achieving and maintaining good health.

Correct Answer: A

Rationale: A community health nurse plays a vital role in promoting health by advocating for health policy changes. By advocating for policy changes that support healthy environments, access to care, and addressing social determinants of health, community health nurses work towards improving the overall health and well-being of the community they serve. While providing direct care to individuals and families, educating the community about healthy lifestyles, and conducting research on community health issues are important aspects of nursing practice, advocating for health policy changes has a broader impact on population health outcomes.

Correct Answer: A

Rationale: The concept of risk is best described as the probability that an individual will develop a specific condition due to exposure to certain factors. It is not about the impact of a health condition on one's life (choice B), the potential harm from a specific condition (choice C), or the likelihood of being exposed to a health hazard (choice D). Understanding risk helps in assessing the chances of developing a particular health issue.
