The term used to describe an increase in blood urea nitrogen (BUN) and serum creatinine is
- A. oliguria.
- B. azotemia.
- C. acute kidney injury.
- D. prerenal disease.
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.

Continuous venovenous hemofiltration is used to
- A. remove fluids and solutes through the process of convection.
- B. remove plasma water in cases of volume overload.
- C. remove plasma water and solutes by adding dialysate.
- D. combine ultrafiltration, convection, and dialysis.
Correct Answer: A
Rationale: The correct answer is A because continuous venovenous hemofiltration (CVVH) primarily removes fluids and solutes through the process of convection. In CVVH, blood flows through a filter where hydrostatic pressure drives plasma water and solutes across a semipermeable membrane. This process mimics the natural filtration that occurs in the kidneys. Choice B is incorrect because CVVH does not specifically target plasma water only but also removes solutes. Choice C is incorrect because CVVH does not involve adding dialysate to remove plasma water and solutes. Choice D is incorrect because while CVVH may involve ultrafiltration and convection, it does not typically include dialysis as a primary mechanism for solute removal.
The nurse notes premature ventricular contractions (PVCs) while suctioning a patient’s endotracheal tube. Which action by the nurse is a priority?
- A. Decrease the suction pressure to 80 mm Hg.
- B. Document the dysrhythmia in the patient’s chart.
- C. Stop and ventilate the patient with 100% oxygen.
- D. Give antidysrhythmic medications per protocol.
Correct Answer: C
Rationale: The correct answer is C: Stop and ventilate the patient with 100% oxygen. This is the priority action because PVCs can lead to life-threatening arrhythmias and inadequate oxygenation. By stopping suctioning and providing 100% oxygen, the nurse ensures proper oxygenation and ventilation, which takes precedence over addressing the dysrhythmia itself. Decreasing suction pressure (choice A) may not address the underlying issue and could potentially harm the patient. Documenting the dysrhythmia (choice B) is important but not as urgent as ensuring adequate oxygenation. Giving antidysrhythmic medications (choice D) should be done under the direction of a healthcare provider and is not the first-line intervention in this situation.
The nurse manager recognizes which action as an effectiveab sirtbr.acotmeg/teys tf or promoting changes in practice?
- A. Asking the clinical nurse specialist to lead a journal clu b on open visitation after each nurse is tasked to read one research article about visitation.
- B. Discussing pros and cons of open visitation at the next staff meeting.
- C. Inviting the nurses with the most experience to develop a revised policy.
- D. Tasking the unit-based nurse practice council to invite volunteers to serve on the council to revise the current policy toward more liberaal bviribs.ciotamt/iteosnt .
Correct Answer: A
Rationale: The correct answer is A because it involves a structured approach to promoting changes in practice. By asking the clinical nurse specialist to lead a journal club on open visitation after each nurse reads a research article, it ensures that all nurses are informed and engaged in the topic. This approach promotes evidence-based practice and encourages active participation.
Option B is less effective as discussing pros and cons at a staff meeting may not ensure that all nurses have the necessary knowledge to make informed decisions. Option C may not consider diverse perspectives and may not involve all staff members equally. Option D involves a select group of volunteers and may not reflect the views of the entire team. Overall, option A is the most inclusive and educational approach to promoting changes in practice.
A patient declared brain dead is an organ donor. The following events occur: 1300 Diagnostic tests for brain death are completed. 1330 primary care provider reviews diagnostic test results and writes in the progress note that the patient is brain deaadb.i r1b.4co0m0/ tePsat tient is taken to the operating room for organ retrieval. 1800 All organs have b een retrieved for donation. The ventilator is discontinued. 1810 Cardiac monitor shows fla tline. What is the official time of death recorded in the medical record?
- A. 1300
- B. 1330
- C. 1400
- D. 1800
Correct Answer: E
Rationale: The correct answer is not provided, but based on the events described, the official time of death recorded in the medical record should be 1810 (Choice D). At this time, the cardiac monitor shows flatline, indicating the cessation of cardiac activity, which is the universally accepted point of declaring death.
Choice A (1300) is incorrect because that is when diagnostic tests for brain death were completed, but the patient was not officially declared dead at that time.
Choice B (1330) is incorrect as this is when the primary care provider reviewed the test results and documented brain death in the progress note, but the patient was not officially declared dead at this time either.
Choice C (1400) is incorrect as there is no significant event occurring at this time that signifies the patient's death.
Therefore, the most appropriate and official time of death recorded in the medical record would be 1810 when the cardiac monitor shows flatline.
A family member tells the nurse, 'I don’t know how I’m going to manage without my mother. She took care of everything for us.' Which response by the nurse is most appropriate?
- A. You will learn how to manage things gradually, and I can provide some resources to help you.
- B. It will be difficult at first, but time will help you adjust to her loss.
- C. Perhaps another family member can take over the responsibilities your mother managed.
- D. It sounds like you will need to seek professional counseling to cope with this loss.
Correct Answer: A
Rationale: The correct answer is A because it acknowledges the family member's feelings while offering support and resources for managing the situation gradually. By providing resources, the nurse empowers the family member to learn how to handle things independently over time. This approach promotes self-reliance and resilience.
Choice B focuses on time rather than active coping strategies, which may not address the family member's immediate needs. Choice C suggests shifting responsibilities to another family member without considering the emotional impact. Choice D jumps to the conclusion of needing professional counseling without exploring other potential solutions or support systems.
