Critical Care Nursing Exam Questions Questions
Question 1 of 9
Continuous venovenous hemofiltration is used to
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.
Question 2 of 9
The nurse is preparing to obtain a right atrial pressure (RA P/CVP) reading. What are the most appropriate nursing actions? (Select all that apply.)
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.
Question 3 of 9
Which statement is a likely response from someone who h as survived a stay in the critical care unit?
Correct Answer: A
Rationale: Rationale: Choice A is the correct answer because it reflects a positive attitude towards potential future treatments in the critical care unit and gratitude for being able to see family again. The survivor acknowledges the past experience but remains optimistic. Summary: - Choice B is incorrect as it shows a strong aversion to hospital care, indicating a preference for death over treatment. - Choice C is incorrect as it focuses on the family's reaction and not the survivor's personal experience or perspective. - Choice D is incorrect as it highlights a trivial aspect (eating) rather than reflecting on the ICU experience or future treatments.
Question 4 of 9
The nurse wishes to assess the quality of a patient’s pain. Which questions is appropriate to obtain this assessment if the patient is able to give a verbal response?
Correct Answer: B
Rationale: The correct answer is B because asking if the pain is sharp, dull, or crushing helps assess the quality of pain, providing specific information on the type of sensation felt. This is crucial for understanding the underlying cause and guiding appropriate treatment. A: Asking about pain being constant or intermittent addresses duration, not quality. C: Inquiring about what makes pain better or worse focuses on triggers, not quality. D: Asking when the pain started addresses onset time, not quality.
Question 5 of 9
The nurse is caring for a patient who is mechanically ventilated. The nurse understands that what statement should be considered when determining apapbrirob.pcormia/ttees tn ursing interventions?
Correct Answer: A
Rationale: The correct answer is A because communication with intubated patients is often challenging due to the presence of an artificial airway, which hinders speech. This understanding is crucial when determining appropriate nursing interventions to ensure effective patient care. Choice B is incorrect because different patients may require different modes of ventilation based on their specific condition, and controlled ventilation may not always be the preferred mode for all patients. Choice C is incorrect as patients with chronic obstructive pulmonary disease often have difficulty weaning from mechanical ventilation due to their underlying respiratory condition. Choice D is incorrect as wrist restraints are not applied to all patients on mechanical ventilation unless absolutely necessary for safety concerns, such as preventing self-extubation.
Question 6 of 9
A patient receiving palliative care for advanced cancer reports fatigue and loss of appetite. Which intervention should the nurse prioritize?
Correct Answer: C
Rationale: The correct answer is C: Provide rest periods to reduce fatigue. Prioritizing rest periods can help alleviate fatigue, a common symptom in patients with advanced cancer. Encouraging small, frequent meals (choice A) may not be effective if the patient has no appetite. Administering appetite stimulants (choice B) may not address the root cause of fatigue. Discussing parenteral nutrition (choice D) is not the priority as it does not directly address the fatigue and loss of appetite reported by the patient. Rest is essential for symptom management and overall well-being in palliative care.
Question 7 of 9
An Ethiopian man with AIDS has recently been admitted to the ICU with a case of pneumonia. The man is new to the U.S. and has no health insurance. He would likely be eligible for the states Medicaid coverage, but does not understand how to access this coverage. Which competency or competencies are most needed in this situation? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Advocacy and moral agency. In this scenario, the Ethiopian man with AIDS is in a vulnerable position due to lack of health insurance and understanding of Medicaid coverage. Advocacy skills are crucial to help him navigate the complex healthcare system and access the necessary resources. Moral agency involves advocating for the patient's rights and well-being, ensuring that he receives appropriate care despite his socioeconomic status. Clinical judgment, collaboration, and systems thinking are important competencies but not as directly relevant in this specific situation of advocating for the patient's access to Medicaid coverage.
Question 8 of 9
The nurse wishes to increase the use of evidence-based practice in the critical care unit where he works. What is a significant barrier to the implementation of evidence-based practice?
Correct Answer: C
Rationale: Rationale: The correct answer is C because lack of knowledge about literature searches hinders the ability to find and utilize evidence-based practice guidelines. Nurses need to be skilled in conducting literature searches to access relevant research. Choices A, B, and D are incorrect as they do not directly impede the implementation of evidence-based practice in the critical care unit.
Question 9 of 9
What nursing delivery of care provides the nurse to plan and direct care of a group of clients over a 24-hour period?
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.
