Critical Care Nursing Exam Questions Questions
Question 1 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 2 of 5
A patient is experiencing severe pain, despite receiving pain medication for the past 24 hours. The patients wife expresses concern about this to the nurse. Which response by the nurse would be most empowering to the patients family?
Correct Answer: C
Rationale: The correct answer is C because it empowers the family to take action by requesting a physician evaluation of the patient's pain control. This step is crucial in ensuring that the patient's pain is adequately managed. By involving the physician, the family can advocate for the patient's needs and potentially explore alternative pain management strategies. Choice A is incorrect because it dismisses the family's concerns and fails to address the need for further evaluation. Choice B may provide temporary relief but does not address the underlying issue of inadequate pain control. Choice D is incorrect as it suggests delaying action, which could lead to prolonged suffering for the patient.
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 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.
Question 5 of 5
To prevent any unwanted resuscitation after life-sustaininga btirrbe.acotmm/teenstt s have been withdrawn, the nurse should ensure that what intervention has been im plemented?
Correct Answer: A
Rationale: The correct answer is A because writing DNR orders before discontinuation of life-sustaining treatments ensures clear communication and legal documentation of the patient's wishes. Choice B is incorrect as family support is essential in end-of-life care. Choice C is incorrect as DNR orders should be established before withdrawing treatment. Choice D is incorrect as the DNR order should be in place before shift change for immediate implementation if needed.
