This step helps in interpreting the RA P/CVP reading correctly. Choice B is incorrect as flushing the catheter with saline is not necessary for obtaining the pressure reading. Choice C is incorrect as inflating the balloon with air is not part of the correct procedure. Choice D is incorrect because obtaining the measurement during exhalation can affect the accuracy of the reading.

The term used to describe an increase in blood urea nitrogen (BUN) and serum creatinine is

Acute kidney injury (C) is a broader term encompassing various causes of kidney dysfunction, not specific to elevated BUN and creatinine. Prerenal disease (D) refers to conditions affecting blood flow to the kidneys, not directly related to elevated BUN and creatinine levels.
What is the main purpose of certification for critical care n ursing?
- A. To assure the consumer that critical nurses will not make a mistake.
- B. To help prepare the critical care nurse for graduate sch ool.

It demonstrates that the nurse has met certain standards and competencies in critical care practice. This certification ensures that the nurse is well-equipped to provide high-quality care to critically ill patients.
A: To assure the consumer that critical nurses will not make a mistake - This choice is incorrect because certification does not guarantee that nurses will not make mistakes. It focuses on validating knowledge and skills rather than infallibility.
B: To help prepare the critical care nurse for graduate school - This choice is incorrect as certification is more focused on practice readiness rather than academic preparation.
C: To assist in promoting magnet status for a facility - This choice is incorrect as magnet status relates more to the overall excellence and quality of nursing care in a facility, not individual certification.

They are best positioned to understand the patient's condition and treatment options. Personal beliefs (A) may not align with medical best practices. Family and friends' recommendations (B) may not be informed by medical knowledge. Wishes previously expressed by the patient (D) are important but may need to be interpreted in the context of the current medical situation, which healthcare professionals can provide.
A nurse who has been recently hired to manage the nursing staff of the ICU is concerned at the lack of evidence-based practice she sees among the staff. Which of the following would be the best step for her to take to promote incorporating evidence into clinical practice?
- A. Only hire nurses certified in critical care nursing.
- B. Leave copies of several different nursing journals in the nurses lounge.
- C. Demonstrate to the staff the best nursing-related search terms to use in Google orYahoo!
- D. Introduce the staff to the PubMed search engine and assign them topics to researchon it.
Correct Answer: D
Rationale: The correct answer is D because introducing the staff to the PubMed search engine and assigning them topics to research on it is the most effective way to promote evidence-based practice. PubMed is a reputable database that contains a vast collection of peer-reviewed articles and research studies, making it a reliable source for evidence. By assigning specific topics, the nurse can ensure that the staff is focusing on relevant and current information, fostering a deeper understanding of evidence-based practice.
Choice A is incorrect because certification in critical care nursing does not guarantee a commitment to evidence-based practice. Choice B is not as effective as it relies on passive exposure to journals rather than active engagement with specific research topics. Choice C is not the best option as using general search terms on search engines like Google or Yahoo may lead to unreliable or outdated information.
What nursing delivery of care provides the nurse to plan and direct care of a group of clients over a 24-hour period?
- A. Case management.
- B. Team nursing.
- C. Primary nursing.
- D. Functional nursing.
Correct Answer: C
Rationale: The correct answer is C: Primary nursing. Primary nursing is a care delivery model where one nurse is responsible for the total care of a group of clients over a 24-hour period. This promotes continuity of care, individualized attention, and better nurse-client relationships. In primary nursing, the nurse plans and directs care, coordinates with other healthcare team members, and serves as the main point of contact for the clients.
A: Case management involves coordinating care across different healthcare providers and services, not necessarily focusing on a specific group of clients over a 24-hour period.
B: Team nursing involves a team of healthcare providers working together to deliver care, rather than one nurse being responsible for a specific group of clients over a 24-hour period.
D: Functional nursing divides tasks among different healthcare team members based on their specific skills, which may not provide the same level of continuity and individualized care as primary nursing.
