Nursing Elites

1. Who among the following individuals wrote a medical code of ethics?

• A. Hammurabi
• B. Thomas Percival
• C. Hippocrates
• D. All of the above

Correct answer: D

Rationale: All of the above individuals contributed to the development of medical ethics. Hammurabi created the earliest known code around 2500 BC. Hippocrates, known for the principle 'Do no harm,' emphasized ethical practices in medicine. Thomas Percival, a physician interested in sociological medicine, authored a Code of Medical Ethics in 1803, which influenced modern medical ethics. Therefore, the correct answer is 'All of the above.' Choices A, B, and C are incorrect because each of them individually wrote a medical code of ethics, making 'All of the above' the most inclusive and accurate answer.

2. Which of the following screening tools have been found to have high diagnostic accuracy for screening for intimate partner violence?

• A. Hurt, Insult, Threaten, and Scream (HITS)
• B. Humiliation, Afraid, Rape, and Kick (HARK)
• C. Slapped, Threatened, and Thrown (STaT)
• D. All of the above

Correct answer: D

Rationale: All of the above screening tools, including HITS, HARK, and STaT, have been found to have high diagnostic accuracy for screening intimate partner violence, as per the National Preventive Services Task Force. These tools are effective in identifying current or recent intimate partner violence. While the Partner Violence screen may have some predictive value for future intimate partner violence, the question specifically focuses on screening tools with high diagnostic accuracy, making 'All of the above' the correct choice. Choices A, B, and C are specific validated screening tools for intimate partner violence, each with its own set of questions that have been shown to be effective in identifying individuals experiencing intimate partner violence. Therefore, 'All of the above' is the most comprehensive and accurate choice for this question.

3. Albert is a patient in the hospital who is scheduled for surgery the following morning. After the pre-operative visit from the anesthesia staff member who has obtained surgical consent, Albert asks for an explanation of what type of surgery he is going to have. He states that he's not sure what he just signed. What is your best response?

• A. Don't worry, they'll explain it in the operating room.
• B. It's standard procedure to get the consent; you don't need to worry.
• C. Let me ask the nurse anesthetist to come back and explain it further.
• D. Someone will review it with you prior to surgery.

Correct answer: C

Rationale: The correct response is to ensure that the patient fully understands the nature of the surgery they are about to undergo. If the patient expresses uncertainty about the procedure they signed consent for, it indicates a lack of informed consent, which is essential before any surgery. By requesting the nurse anesthetist to return and provide a more detailed explanation, the patient can make an informed decision. Choices A, B, and D do not address the issue of the patient's lack of understanding and the need for informed consent, making them incorrect. Option C is the best course of action to rectify the situation and ensure the patient's understanding and consent are properly obtained.

4. A client is having blood tests and has an elevated lymphocyte level. Based on knowledge of cellular components, what does the nurse know about these cells?

• A. Contain histamine and provide protection during allergic reactions
• B. Are involved in phagocytosis
• C. Provide protection and immunity against foreign substances
• D. Carry hemoglobin and oxygen to body tissues

Correct answer: C

Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue. Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes. Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages. Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.

5. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.
