Critical Care Nursing Exam Questions Questions
Question 1 of 5
Which nursing actions for the care of a dying patient can the nurse delegate to a licensed practical/vocational nurse (LPN/LVN) (select all that apply)?
Correct Answer: A
Rationale: The correct answer is A because providing postmortem care to a dying patient is a task that can be safely delegated to an LPN/LVN. This includes tasks such as preparing the body, cleaning, and positioning after death. LPNs/LVNs are trained and competent in performing these duties under the supervision of a registered nurse or physician. Choices B, C, and D are incorrect because they involve critical thinking, assessment, and teaching skills that are typically within the scope of practice of a registered nurse. Encouraging family members to talk with the patient, determining assessment frequency, and educating about signs of approaching death require a higher level of nursing judgment and expertise, which is beyond the scope of an LPN/LVN's role.
Question 2 of 5
What should a designated healthcare surrogate base healthcare decisions on?
Correct Answer: C
Rationale: The correct answer is C because the healthcare surrogate should base decisions on recommendations of the physician and healthcare team who have the expertise to provide medical advice. 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.
Question 3 of 5
The nurse manager recognizes which action as an effectiveab sirtbr.acotmeg/teys tf or promoting changes in practice?
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.
Question 4 of 5
The nurse is caring for a 70-kg patient in septic shock with a pulmonary artery catheter. Which hemodynamic value indicates an appropriate response to therapy aimed at enhancing oxygen delivery to the organs and tissues?
Correct Answer: C
Rationale: The correct answer is C: Mixed venous (SvO2) of 40%. In septic shock, improving oxygen delivery to tissues is vital. SvO2 reflects the balance between oxygen delivery and consumption. A value of 40% indicates adequate oxygen delivery to tissues. A: Arterial lactate level of 1.0 mEq/L - Although a low lactate level is good, it does not directly indicate improved oxygen delivery. B: Cardiac output of 2.5 L/min - Cardiac output should ideally increase to improve oxygen delivery, so 2.5 L/min is low for a 70-kg patient. D: Cardiac index of 1.5 L/min/m2 - Cardiac index is cardiac output adjusted for body surface area. 1.5 L/min/m2 is low and indicates inadequate cardiac function for a patient in septic shock.
Question 5 of 5
What is the main purpose of certification for critical care n ursing?
Correct Answer: D
Rationale: The correct answer is D: To validate a nurse�s knowledge of critical care nursing. Certification in critical care nursing validates a nurse's expertise and knowledge in this specialized area of nursing. 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.
