Correct Answer: B

Rationale: The correct answer is B because volunteering to serve on a disaster response planning committee demonstrates awareness of current events affecting critical care nursing. By actively participating in planning for potential disasters, the nurse shows a proactive approach to staying informed and prepared for emergencies. This behavior indicates a commitment to staying up-to-date with the evolving landscape of critical care nursing. Choices A, C, and D are incorrect because: A: Participating in recruitment efforts may be important but does not directly demonstrate awareness of current events affecting critical care nursing. C: Adhering to basic nursing program content is necessary but does not show active engagement with current events in critical care nursing. D: Attending hospital-mandated in-services is valuable, but without seeking additional education or involvement in current events, it does not illustrate awareness of the changing critical care nursing environment.

Correct Answer: B

Rationale: The correct answer is B: azotemia. Azotemia refers to an increase in BUN and serum creatinine levels, indicating impaired kidney function. Oliguria (A) is a decrease in urine output, not specific to BUN and creatinine levels. 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.

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C is not the best option as using general search terms on search engines like Google or Yahoo may lead to unreliable or outdated information.

Correct Answer: A

Rationale: The correct answer is A because comparing measured pressures with other physiological parameters ensures accuracy and consistency. 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.

Correct Answer: C

Rationale: The correct answer is C because supervised and guided visits with the infant allow the client to bond with her baby in a safe and structured environment, promoting maternal-infant attachment while ensuring the safety and well-being of both. Restricting visitors who irritate the client (choice A) may increase feelings of isolation and distress. Full rooming-in for the infant and mother (choice B) may overwhelm the client with severe postpartum depression. Daily visits with her significant other (choice D) may not directly address the client's need for bonding with her infant.
