The nurse is teaching a client about communicable diseases and explains that a portal of entry is:

Correct Answer: D

Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.

Correct Answer: B

Rationale: Individual state laws mandate the reporting of infectious diseases. The list of reportable diseases varies from state to state and is overseen by state health departments. While the CDC plays a significant role in disease surveillance, reporting infectious diseases is primarily governed by individual state laws. The CDC's role is to provide support, guidance, and expertise to state health departments. The National Institutes of Health (NIH) primarily focus on biomedical and health-related research, not on mandating disease reporting. Health and Human Services (HHS) is a federal department that oversees various agencies, but the responsibility for mandating disease reporting lies with individual states.

Correct Answer: B

Rationale: A nursing advocate does not make decisions for others but instead empowers individuals to make decisions for themselves. By encouraging individuals to make their own decisions and supporting them in this process, nursing advocates uphold the principle of self-determination. This approach respects the autonomy and independence of individuals in managing their care. Therefore, the correct answer is to 'encourage persons to make decisions for themselves and act with or on behalf of the person to support those decisions.' Choices A, C, and D are incorrect as they do not align with the role of a nursing advocate in promoting patient autonomy and self-determination.

Correct Answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.

Correct Answer: D

Rationale: The five rights of medication administration are dose, client, drug, route, and time. The correct answer is 'routine' as it is not commonly recognized as one of the essential rights in medication administration. Choice A, client, is necessary to ensure the right medication is administered to the right individual. Choice B, drug, is crucial to confirm the correct medication is given. Choice C, dose, is essential to ensure the right amount of medication is administered. Choice D, routine, is not typically included in the five rights of medication administration and is therefore the correct answer.
