Nursing Elites

1. Which of the following lab values is elevated first after a client has a myocardial infarction?

• A. LDH
• B. troponin
• C. CPK
• D. SGOT

Correct answer: B

Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.

2. An 85-year-old client is eligible for Medicare-reimbursable home care services. Referral is contingent on meeting which of the following criteria?

• A. homebound status, requiring skilled therapy care
• B. immediate previous hospitalization for acute care
• C. age
• D. requirement of nursing and social work support

Correct answer: A

Rationale: The correct criteria for Medicare-reimbursable home care services include the client being homebound and requiring a skilled service, such as physical therapy, occupational therapy, speech therapy, nursing, or social work. Choice A is correct because it aligns with these requirements. Choice B is incorrect as immediate previous hospitalization is not a prerequisite for home care services. Choice C is incorrect as age alone does not determine eligibility for Medicare-reimbursable home care services. Choice D is incorrect as the requirement of nursing and social work support alone is not sufficient for Medicare-reimbursable home care services.

3. What is the best definition of ethics in nursing?

• A. advocating for the client
• B. knowing your scope of practice
• C. being able to differentiate right from wrong
• D. being willing to report violations

Correct answer: C

Rationale: Ethics in nursing refers to the moral principles that govern a nurse's behavior and decision-making. It involves being able to differentiate right from wrong, making choices that are morally sound, and upholding integrity in patient care. While advocating for the client (choice A) is an important aspect of nursing care, it does not fully encompass the broad concept of ethics. Knowing your scope of practice (choice B) is essential for safe and competent care but is not a comprehensive definition of ethics. Being willing to report violations (choice D) is part of ethical practice, but it is not the core definition of ethics in nursing.

4. The nurse provides a postoperative client with an analgesic medication and darkens the room before the client goes to sleep for the night. The nurse's actions:

• A. help decrease stimuli from the cerebral cortex.
• B. stimulate hormonal changes in the brain.
• C. help the client's circadian rhythm.
• D. alert the hypothalamus in the brain.

Correct answer: A

Rationale: The nurse's actions of providing an analgesic medication and darkening the room aim to decrease stimuli from the cerebral cortex. Reduction of environmental stimuli, especially light and noise, from the cerebral cortex, which is an area of arousal, facilitates sleep. By decreasing input to this area, the client is more likely to fall asleep and stay asleep. Choices B, C, and D are incorrect because the scenario does not involve stimulating hormonal changes, influencing the circadian rhythm, or alerting the hypothalamus.

5. What is a significant point about Shigella that the nurse should acknowledge upon identifying it in a stool culture?

• A. People who have been in contact with the client need to be tested.
• B. Shigella is an airborne infection.
• C. Shigella is a bacteria sometimes found in stagnant water.
• D. The nurse should wear a one-way breathing apparatus when giving client care.

Correct answer: C

Rationale: Shigella is a bacteria sometimes found in stagnant water. Transmission of Shigella is typically oral-fecal, so good hand washing and the use of gloves are the best means of prevention when caring for a client with Shigella. The bacteria can be found in food and water contaminated by fecal material. Incidences of Shigella are reportable in many states. Choices A, B, and D are incorrect. While it is important for close contacts to be aware and practice good hygiene, testing is not routinely indicated. Shigella is not an airborne infection; it is transmitted through contaminated food or water. A one-way breathing apparatus is not necessary for caring for a patient with Shigella; standard precautions, including handwashing and gloves, are sufficient.
