Critical Care Nursing Exam Questions Questions
Question 1 of 5
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?
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.
Question 2 of 5
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 3 of 5
The nurse is caring for a patient receiving continuous norepinephrine (Levophed) IV infusion. Which patient assessment finding indicates that the infusion rate may need to be adjusted?
Correct Answer: B
Rationale: The correct answer is B because a low Mean Arterial Pressure (MAP) indicates inadequate perfusion, which may require adjusting the norepinephrine infusion rate to increase blood pressure. A: A heart rate of 58 beats/minute is within a normal range and may not necessarily indicate a need for adjustment. C: Elevated Systemic Vascular Resistance (SVR) may be an expected response to norepinephrine and does not necessarily indicate a need for adjustment. D: A low Pulmonary Artery Wedge Pressure (PAWP) may indicate fluid volume deficit but does not directly relate to the need for adjusting norepinephrine infusion rate.
Question 4 of 5
The nurse is caring for 80-year-old patient who has been tr eated for gastrointestinal bleeding. The family has agreed to withhold or withdraw additional treatment. The patient has a written advance directive specifying requests. The directive notes that the patient wants food and fluid to be continued and to be made physically comfortable. Th e nurse anticipates that several orders may be written to comply with this request, including which of the following? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: "Do not resuscitate." In this scenario, the patient's advance directive specifies a desire for comfort measures and continuation of food and fluids. A DNR order aligns with this directive by respecting the patient's wish to avoid aggressive life-saving measures. This choice prioritizes the patient's autonomy and quality of life. Other options (B, C, D) are not aligned with the patient's wishes. Changing antibiotics or stopping blood transfusions may be unrelated to the patient's comfort or food/fluid preferences. Discontinuing tube feeding goes against the directive's request for food and fluid continuation.
Question 5 of 5
The nurse responds to a ventilator alarm and finds the patient lying in bed holding the endotracheal tube (ET). Which action should the nurse take next?
Correct Answer: D
Rationale: The correct action is D: Manually ventilate the patient with 100% oxygen. This is crucial to ensure adequate oxygenation and prevent hypoxia. Holding the ET tube can lead to extubation and airway compromise. Activating the rapid response team (A) may delay immediate intervention. Providing reassurance (B) is important but not the priority in this situation. Calling the health care provider (C) to reinsert the tube would also lead to a delay in providing essential respiratory support.
