A school nurse is implementing health screenings. Which of the following assessment findings should the nurse recognize as the highest priority?

The correct answer is Choice B because, "Clients receive Medicare benefits when eligible." Distributive justice is the ethical principle that resources should be allocated fairly among members of society. The outcome of clients receiving Medicare benefits when eligible is an example of distributive justice because it ensures that eligible clients have access to healthcare resources that are distributed fairly based on their need for them.

Choice A is wrong because, "Clients demonstrate completion of advance directives," is not the correct answer because it is an example of autonomy, which is the ethical principle that individuals have the right to make decisions about their own healthcare. Choice C is wrong because, "Clients verbalize their right to refuse treatment," is an example of informed consent, which is the ethical principle that individuals have the right to make decisions about their own healthcare based on accurate information. Choice D is wrong because, "Clients understand their right to confidentiality," is an example of confidentiality, which is the ethical principle that healthcare information should be kept private and secure.

The correct answer is B, euphoria. Heroin is an opioid that produces a feeling of intense pleasure, or euphoria, as it binds to opioid receptors in the brain. Other physical effects of heroin use may include constricted (not dilated) pupils, slowed breathing (not tachypnea), and droopy eyelids (not nystagmus).

Heroin is an opioid drug that affects the central nervous system, leading to a range of physical and psychological effects. One of the most common effects of heroin use is euphoria, which is a feeling of intense happiness, pleasure, and wellbeing. This is caused by the drug binding to opioid receptors in the brain, triggering the release of dopamine, a neurotransmitter associated with pleasure and reward.

Other physical effects of heroin use can include dilated pupils (Choice A is wrong because), as the drug can affect the muscles in the iris, causing them to expand. Tachypnea (Choice C is wrong because), or rapid breathing, can also occur as a result of the drug's effects on the respiratory system. Nystagmus (Choice D is wrong because), or involuntary eye movements, can be a sign of opioid intoxication, but is not as common as euphoria or dilated pupils.
