Nursing Elites

1. Which of the following conditions may warrant a serum creatinine level?

• A. Rhabdomyolysis
• B. Digitalis toxicity
• C. Glomerulonephritis
• D. All answers are correct

Correct answer: D

Rationale: A serum creatinine level may be warranted in conditions that can affect renal function or cause muscle breakdown. Rhabdomyolysis, characterized by muscle injury and breakdown, can lead to elevated creatinine levels due to the release of creatinine from muscles. Digitalis toxicity can impair renal function, leading to a need for monitoring creatinine levels. Glomerulonephritis, an inflammatory condition affecting the kidney's filtering units, can also impact renal function and require assessment of creatinine levels. Therefore, all the provided conditions may warrant a serum creatinine level to assess renal function and muscle breakdown.

2. 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.

3. A client has volunteered to take part in a research study. After participating for two months, he decides that he can no longer tolerate the study and decides to leave. What are the client's rights in this situation?

• A. The client has a right to be released from the study but must reimburse the researchers for charges incurred
• B. The client has a right to be released from the study without any liability
• C. The client has a right to be released from the study but is prohibited from participating in any future studies
• D. The client does not have the right to be released from the study; he must finish his participation

Correct answer: B

Rationale: When a client voluntarily participates in a research study and later decides to withdraw, they have the right to be released from the study without any liability. It is unethical to force a participant to continue in a study against their will as this violates their autonomy and personal rights. Choice A is incorrect as it suggests that the client must reimburse the researchers for charges incurred, which is not typically the case unless agreed upon beforehand. Choice C is incorrect as there is no standard practice prohibiting a participant from future studies just because they withdrew from a current one. Choice D is incorrect because participants always have the right to withdraw from a research study at any time.

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 client has a right-sided chest tube with 50 cc of serosanguinous fluid in the collection chamber and air bubbles are collecting in the water seal chamber. What is the most appropriate action for the nurse to take at this time?

• A. Do nothing; this is a normal response
• B. Strip the tubing to remove any clots
• C. Place a clamp on the tube near the client's chest
• D. Remove the collection chamber and connect the tubing to a new device

Correct answer: C

Rationale: The water seal of a chest tube acts as a one-way valve. Air bubbles in the water seal indicate a leak between the client and the chamber. The nurse should briefly clamp the tube near the client's chest to locate the source of the leak. Once identified, the nurse should unclamp the tubing and notify the physician immediately. Choice A is incorrect because air bubbles in the water seal chamber are not a normal finding and indicate a leak. Choice B is incorrect as stripping the tubing could aggravate the issue and is not the initial appropriate action. Choice D is incorrect as it does not address the immediate need to locate and address the leak.
