Rationale: Utilitarianism is an ethical theory that focuses on producing the greatest overall balance of good over bad consequences for everyone involved. In the context of the situation described, nurses being floated to areas of most need during a nursing shortage is an example of utilitarianism in action. The decision to float nurses is aimed at maximizing the benefit to the greatest number of patients by ensuring that critical care is provided where it is most needed, even if it may cause inconvenience or discomfort to the nurses being floated. This decision aligns with the principle of maximizing overall utility and promoting the greater good, which are central tenets of utilitarianism.

Rationale: Insulinoma is a rare neuroendocrine tumor that arises from pancreatic beta cells, leading to excessive production and secretion of insulin.

Correct Answer: C

Rationale: The patient's symptoms of watery diarrhea, abdominal cramps, and nausea after consuming contaminated water from a stream during a camping trip suggest an infection caused by Cryptosporidium parvum. Cryptosporidium is a protozoan parasite that is commonly transmitted through contaminated water sources. Laboratory tests detecting oocysts in the stool sample are characteristic of Cryptosporidium infection.

Correct Answer: A

Rationale: By randomly selecting individuals in the community for the project, Nurse Mary is upholding the ethical principle of autonomy. Autonomy refers to respecting individuals' right to make their own decisions and choices. In this scenario, Nurse Mary is not imposing her own preferences or biases but rather allowing individuals in the community to have an equal opportunity to participate in the project. Random selection ensures that the process is fair and gives everyone an equal chance to be involved, respecting their autonomy.

Correct Answer: C

Rationale: The most appropriate response by the nurse is, "If I were you, I will get a second opinion." This response acknowledges the seriousness of the situation and the life-changing decision the patient has been told to make. Suggesting the patient seek a second opinion is essential as it encourages the patient to explore all options and ensures they have considered all possibilities before proceeding with a major surgery like an above-the-knee amputation. It shows the nurse's support for the patient while also advocating for the patient's right to make an informed decision about their healthcare.
